KNF LABOPORT N 96 mini diaphragm vacuum pump, chemical-resistant, speed-controlled, 7 l/min, 322806
Compact performance for the laboratory workstation: KNF LABOPORT ® N 96 The KNF LABOPORT ® N 96 redefines what a compact laboratory pump is capable of. With MPN 322806, you get a highly flexible system that has been specially developed for applications where space-saving design, chemical resistance and precise control are required. Despite its very small footprint, this mini diaphragm vacuum pump delivers impressive performance and is ideal for filtration, solid-phase extraction (SPE), the removal of liquid supernatants or as a fore-vacuum pump for turbomolecular pumps. Chemical resistance meets maintenance-free operation A key advantage of the N 96 is its choice of materials. The pump head is made of robust PPS (polyphenylene sulphide), the diaphragm is PTFE-coated and the valves are made of FKM. This combination makes the pump extremely resistant to aggressive gases and vapours. Unlike oil-lubricated rotary vane pumps, the diaphragm principle of the N 96 operates 100 per cent oil-free. For you, this means: no contamination of your samples by oil vapours, no disposal of waste oil and completely maintenance-free operation in day-to-day laboratory work. You can transfer, evacuate and compress samples accurately and cleanly. Integrated speed control for gentle processes The LABOPORT ® N 96 is not simply ‘On’ or ‘Off’. It features integrated speed control, which is operated intuitively via a rotary knob on the top. This allows you to adjust the flow rate continuously to suit your process – from gentle suction right through to full power. The visual status indicator is particularly innovative: the colour of the LED lighting on the rotary knobs changes depending on the operating status (e.g. standby, operation), so you can see immediately – even from a distance – what the pump is currently doing. Quiet, low-vibration and space-saving In modern laboratories, space is at a premium and noise is a nuisance. The N 96 scores highly in both respects: with its extremely compact design, it fits into any nook or directly into the fume cupboard without blocking valuable worktop space. Thanks to its advanced diaphragm technology and brushless DC motor, it also operates very quietly and with minimal vibration. This is easier on the user’s nerves and allows for concentrated work right next to the unit. Versatility in application and pressure Although primarily known as a vacuum pump (ultimate vacuum < 130 mbar abs.), the N 96 can also be used as a compressor, delivering a working overpressure of up to 2.5 bar. The flow rate of up to 7 litres per minute (at atmospheric pressure) ensures rapid results during filtration. The plug-in power supply with wide-range input allows for use worldwide. Detailed technical specifications Flow rate (max.): 7 l/min (0.42 m³/h) at atmospheric pressure Final vacuum: < 130 mbar (abs.)

Bürkle foot-operated solvent pump with outlet hose and tap, 5603-3000
The Bürkle solvent pump, featuring foot operation, a discharge hose and a shut-off valve, represents a high-purity, occupational safety-optimised system solution for the contamination-free transfer and filling of organic solvents, acids, alkalis and flammable liquids from drums and large containers. In industrial production facilities, chemical laboratories and pharmaceutical filling plants, handling highly volatile or flammable media places the highest demands on explosion protection and ergonomics. Through the consistent use of chemically inert materials such as stainless steel and PTFE (Teflon), the purity of the filled media is fully preserved. For laboratory managers, health and safety officers and procurement staff in the B2B sector, this foot-operated pump offers the highest level of process reliability, as it enables precise, drip-free dosing whilst keeping the operator’s hands free to hold the target vessel. Ergonomic foot operation for maximum occupational safety The mechanical system architecture is characterised by convenient foot operation via a separate, robust foot bar. Activating the pump with the foot builds up a transient overpressure in the container, which delivers the liquid gently and evenly upwards through the riser tube. This contact-free operation offers a decisive advantage in terms of occupational safety: the operator has both hands free to position measuring cylinders, flasks or canisters precisely beneath the spout. This effectively minimises accidental spillage or dangerous splashes of corrosive chemicals during daily field use. Material inertness for high-purity media All functional components of the drum pump that come into contact with samples and media are manufactured from materials of the very highest quality. The robust immersion tube and the media-carrying valves are made of high-purity type 1.4301 (AISI 304) stainless steel, whilst all seals and the flexible outlet hose are made of chemically unrivalled PTFE. This material-science specification guarantees universal resistance to highly aggressive organic solvents such as acetone, ethanol, methanol or toluene. As the pump is designed to be completely free of lubricants or plastics containing plasticisers, high-purity sample quality is permanently guaranteed without any cross-contamination from the materials. Gas-tight seal and controlled drainage of residual quantities The Bürkle solvent pump is securely and airtightly fixed in the container’s bunghole via a highly stable drum coupling. This gas-tight system seal reliably prevents harmful solvent vapours from entering the ambient air and the breathing zone of laboratory staff during the pumping process. The flexible, 1.2-metre-long PTFE outlet hose is fitted with a precision stainless steel shut-off valve. This valve allows for absolutely precise, drip-free dispensing of even the smallest volumes. Thanks to the infinitely variable height-adjustable drum thread, the pump’s immersion depth can be perfectly adapted to the specific container geometry, ensuring excellent drainage of residual quantities. Technical details Pump characteristics & kinematics Pump type: Solvent pump / drum pump with manual foot operation Flow rate: approx. 20 litres per minute (depending on the viscosity of the medium) Operating mode: Foot-operated via a separate foot bar with pressure hose Dosing: Precise control via manual stainless steel shut-off valve Materials Science & Media Compatibility Materials in contact with the medium: Stainless steel 1.4301 (AISI 304) and PTFE (Teflon) Sealing materials: Pure, chemically inert PTFE Lubricants: Manufactured entirely free of lubricants and plasticisers Chemical resistance: Optimised for high-purity solvents, alcohols, flammable liquids and low-viscosity chemicals Design & Dimensions Immersion depth (immersion tube length): 950 mm (continuously height-adjustable) Immersion tube diameter: 18 mm Outlet type: Flexible PTFE outlet hose with stainless steel tap Outlet hose length: 1.2 metres Standard container connection: Suitable for steel drums with M64x4 internal thread (drum coupling included) Health and safety & approvals Explosion protection: Suitable for flammable media when used in conjunction with an anti-static earthing kit Emission control: Gas-tight system seal against hazardous solvent vapours Scope of supply 1 x Bürkle solvent pump, foot-operated base unit (MPN: 5603-3000) 1 x flexible PTFE outlet hose (length 1.2 metres) with stainless steel shut-off valve 1 x foot pedal bar including air connection hose 1 x drum coupling for M64x4 steel drum thread 1 x operating instructions Custom requirements & accessories When dispensing highly flammable and combustible solvents (such as petrol, toluene or isopropanol), friction can generate dangerous electrostatic charges. To ensure explosion protection in accordance with strict health and safety guidelines, the use of a suitable anti-static kit is essential. Our range includes the original Bürkle anti-static kit (earthing cable with brass clamps), which safely dissipates electrostatic energy to earth in a way that is gentle on materials and ensures process reliability. For use with plastic drums, sheet metal containers or other containers, we also offer a comprehensive range of threaded adaptors (e.g. for Mauser threads, Tri-Sure or 2-inch coarse threads). Please make use of our technical procurement service to ensure the safe configuration of your hazardous materials workstation.
Bürkle Hand Pump for Solvents, V2A Stainless Steel, for Containers up to 60 L, 5603-1000
Anyone who scoops solvent from a 60-litre drum using a beaker or a jug risks splashes and direct skin contact with the liquid. The hand pump for solvents, on the other hand, operates on the principle of positive pressure: A pump ball forces air into the sealed drum; the resulting overpressure pushes the solvent out in a controlled manner through the fixed spout. This allows flammable solvents to be dispensed in measured quantities without having to tip the drum over or leave it open permanently.Operation without suctionUnlike a suction pump, the hand pump does not create a vacuum in the riser tube, but rather positive pressure inside the drum itself. The pump bulb is operated by hand; air flows through a tube into the drum, whilst the solvent rises separately to the spout. The shut-off valve at the end of the spout, made of stainless steel and PTFE, stops the flow immediately once the receiving container is full.For drums up to 60 l with a G2-inch threadThe pump fits containers with a G2-inch external thread and a capacity of up to approximately 60 l. The dip tube can be continuously adjusted to the actual depth of the drum; at full immersion depth, it extends up to 60 centimetres into the drum. With a flow rate of around 10 l per minute and a viscosity of up to 500 mPa·s, the pump is suitable for low- to medium-viscosity solvents. The 12-millimetre external diameter of the outlet fits standard funnels and canister openings, allowing the target container to be filled directly beneath the outlet elbow.Materials in contact with solventsAll parts in contact with the medium are made of 1.4301 (V2A) stainless steel and PTFE. Both materials are chemically resistant to organic solvents and aromatic compounds and can withstand regular cleaning after filling. Unlike a plastic pump, stainless steel does not swell when frequently exposed to more aggressive solvents and retains its fit, even after many filling cycles.Independent of mains power and compressed airThe hand pump requires neither a mains power connection nor a compressed air supply; it operates solely by means of the pump ball in the hand. This makes it ideal for workplaces where there is no compressed air network, such as in smaller workshops, for mobile operations or in storage areas away from the main infrastructure. Those who only open a drum occasionally can therefore manage without having to purchase a compressor.Safety when handling flammable liquidsBürkle expressly refers to the explosion protection guidelines for handling flammable, highly combustible liquids when using this pump: all parts must be earthed; in addition, the manufacturer recommends an anti-static kit. The product page does not specify a particular ATEX certification; the advice is intended as a recommendation for safe operation.If a different container or drive type is requiredFor tinplate canisters with bellows closures, the solvent pump for tinplate canisters is available as a hand pump of identical design, featuring a suitable adapter instead of a G2-inch thread. If both hands need to remain free, or if larger 220-litre drums are being used, the foot-operated solvent pump with spout is the more suitable choice. For small containers such as bottles or canisters up to 10 l with a GL45 thread, the Mini solvent pump is more suitable.Typical applicationsContamination-free dispensing of organic solvents and aromatic compounds from 60-litre drumsPrecise dispensing of flammable liquids in the laboratory, workshop or warehouseDecanting into smaller containers without tilting or opening the drumDrums with G2-inch threads in the chemical industry and in tradeTechnical detailsMaterialStainless steel 1.4301 (V2A), polytetrafluoroethylene (PTFE)Drive typemanually operatedPump typePressure pumpThreadG 2 inches, external threadFlow rate approx.10 l/minViscosity up to approx.500 mPa·sPipe diameter15 mmImmersion tube diameter15 mmLength of outlet bend185 mmOuter diameter of outlet12 mmMax. immersion depth60 cmFor containers up toapprox. 60 lScope of deliveryHand pump with fixed spout and shut-off valveService and procurementBusinesses with multiple drum sizes or container types often coordinate their order with the appropriate foot-operated or mini version, so that the right pump is to hand for every container.

IKA VACSTAR lite Starter Solution, diaphragm vacuum pump, including emission condenser, 2 mbar, 0010014496
Part of the IKA Specials Q4/2026, valid until 31 December 2026. The crossed-out price is IKA's recommended list price. Our promotional price is net.Compact, high-performance equipment for your laboratory: the IKA VACSTAR lite Starter Solution With the IKA VACSTAR lite Starter Solution (MPN 0010014496), you get a perfectly coordinated vacuum package that combines space-saving design, high suction power and environmental awareness. This 4-cylinder diaphragm vacuum pump has been developed to handle the demanding tasks of everyday life in a modern laboratory – whether as a partner for your rotary evaporator, for drying cabinets or for filtration tasks. For you, the ‘Starter Solution’ means: unpack, connect and start safely, as the essential safety emission capacitor (VSE 1) is already included in the scope of delivery. Small but mighty: performance in a minimal space The VACSTAR lite impresses with its award-winning, extremely compact design. With dimensions barely larger than a drinks bottle, this pump fits into even the smallest of nooks or directly inside a fume cupboard. But don’t be fooled by its size: with an impressive pumping speed of 22 l/min and an outstanding ultimate vacuum of 2 mbar, it’s right up there with the big players. This high pumping speed guarantees fast process times and efficient operation, even with low-boiling-point solvents. Protection for the laboratory and the environment: the safety emission condenser A highlight of this set is the included VSE 1 vacuum safety emission condenser. Vacuum pumps extract vapours that should often not simply be released into the room air. The VSE 1 reliably prevents solvent vapours from entering the laboratory atmosphere. This not only protects staff health from harmful emissions but also safeguards the environment. Furthermore, the condenser enables the effective recovery of valuable solvents, which reduces operating costs and promotes sustainable working practices. Chemical-resistant and low-maintenance As a dry diaphragm pump, the VACSTAR lite operates 100% oil-free. For you, this means: no tedious oil changes, no disposal of waste oil and no contamination of your samples by oil vapours. All parts in contact with the process fluid are made from high-quality, chemical-resistant materials (PTFE diaphragms, FKM valves, etc.). This makes the pump extremely resistant to aggressive chemicals and vapours, guaranteeing a long service life and low maintenance costs. Intuitive operation and process reliability The “lite” version focuses on the essentials: pure functionality. Operation is intuitive via a rotary knob, which allows you to continuously adjust the speed and thus the suction capacity. This enables the process to be started gently to prevent boiling delays, or ramped up to maximum performance. An integrated non-return valve also protects the system against backflow when the pump is switched off or in the event of a power cut.

IKA VACSTAR digital Vacuum Pump, Diaphragm Pump with Digital Speed Display, 22 l/min, 0020016236
The IKA VACSTAR digital (MPN 0020016236) is a dry 4-chamber diaphragm vacuum pump with digital speed display. Anyone who has so far operated a purely analogue pump without feedback on the current speed can see here at a glance which setting is currently in use, without depending on full automation. The VACSTAR digital is thus positioned between the purely manual VACSTAR lite and the VACSTAR control with integrated vacuum controller: more control than with a purely analogue pump, but without the additional cost of a permanently installed controller when it is not yet needed for the application in question. Digital display with simple turn-and-push operation The parameters are set with a turn-and-push knob, and an LED display shows the current speed in real time. The pumping speed of 22 l/min (1.32 m³/h) and an ultimate vacuum of 2 mbar reliably cover typical tasks such as rotary evaporators, drying ovens or filtrations. The speed range extends from 285 to 1200 revolutions per minute, regulated by an analogue speed-vacuum control with two-point control for stable, readily reproducible process behaviour. Prepared for later automation An analogue cable for connecting an external vacuum controller of type VC 10 is already included in the scope of delivery. Anyone who wants to run automated processes, for example a programmed distillation ramp, can extend the pump with the VC 10 at any time without having to buy an additional connecting cable and without having to replace the pump itself with another model. For the protection of laboratory air and the environment, the VSE 1 vacuum safety emission condenser is also recommended. It prevents solvent vapours from being released into the room air and can be retrofitted at any time if required. Chemically resistant and designed for continuous operation All parts in contact with the product are made of Al2O3, PTFE, FFPM, PPS and NBR, and the housing of coated die-cast aluminium and thermoplastic. As a dry-running pump, the VACSTAR digital works entirely without operating oil, so oil changes and the disposal of waste oil are eliminated and samples cannot be contaminated by oil vapours. This combination of materials makes the pump particularly resistant to aggressive solvents and ensures low-maintenance continuous operation in everyday laboratory work, even with daily changes between different solvents. Connection, format and operating values With dimensions of 150 x 375 x 370 millimetres and a weight of 11.5 kilograms, the VACSTAR digital is designed for a fixed place at the laboratory workstation, for example next to a rotary evaporator or drying oven. It is connected to 100 to 240 volts at 50 or 60 hertz with a device power consumption of 130 watts in operation and 3 watts in standby. Both an RS232 and a USB interface are available for connection to laboratory software, and the housing is classified IP 20. Robust design for daily laboratory use The lower housing made of coated die-cast aluminium in combination with thermoplastic components is designed for daily continuous use in the laboratory and withstands occasional solvent splashes without visible damage to the housing. The permissible ambient temperature of 5 to 40 degrees Celsius and a tolerated relative humidity of up to 80 percent at 31 degrees Celsius, decreasing linearly to a maximum of 50 percent at 40 degrees Celsius, make the pump suitable even for laboratories without continuous air conditioning. With a sound pressure level of 54 dB(A) at minimum pressure, operation next to the workstation remains pleasantly quiet. Typical applications As a digital intermediate step between manual operation and a fully integrated controller, the VACSTAR digital is particularly suitable for the following applications: Rotary evaporator operation with direct reading of the current speed instead of estimating from the scale on the knob Vacuum drying in drying ovens with a traceable speed setting that can be read on the display Vacuum filtration in the routine laboratory where digital control without full automation is already sufficient Laboratory workstations that are to be retrofitted later with a VC 10 vacuum controller for full automation Training and practical courses in which the digital speed display supports participants' understanding of the process Workstations with several users where a traceable speed setting is more important than estimating from a scale Technical details Pump type4-chamber diaphragm vacuum pump, dry Delivery rate max.

Bürkle Foot-operated Solvent Pump with Outlet Elbow, V2A Stainless Steel, for Drums up to 220 L, 5603-1100
When dispensing from a 220-litre steel drum, both hands are often needed: one holds the receiving container, whilst the other is supposed to guide the spout. The foot-operated solvent pump solves this problem by being activated via a foot pedal: the operator has both hands free for the container and does not need to touch the pump itself whilst the solvent flows through the fixed spout.Foot operation instead of a hand pumpInstead of a pump ball, the operator presses a pedal at the base of the pump. Each press forces air into the drum and builds up excess pressure, which pushes the solvent through the riser pipe to the outlet elbow. This completely frees up the hands and, during repeated filling over several minutes, is noticeably more comfortable than a hand pump that has to be held down continuously. Even with larger 220-litre drums, which require more strokes, the effort required is distributed more evenly when using the foot.For drums up to 220 l with a G2-inch threadThe pump is designed for steel drums with a G2-inch external thread and is suitable for containers up to around 220 l. The 21-millimetre-diameter dip tube can be continuously adjusted to the depth of the drum; at full immersion, it extends up to 95 centimetres into the drum. With a flow rate of around 20 l per minute and a viscosity of up to 500 mPa·s, it fills a container noticeably faster than the smaller hand pump for 60-litre drums.Fixed spout for stationary fillingThe 300-millimetre-long outlet elbow with shut-off valve is fixed in place and not flexible. This is ideal when the target container is positioned directly beneath or next to the pump, as the short, rigid path from the drum to the spout, with an outer diameter of 13 millimetres, allows for stable, easily controllable flow. If, on the other hand, a container needs to be filled that is further away, raised or positioned at an angle, the identically constructed foot-operated solvent pump with discharge hose and tap is the more suitable option: It has the same pump body and the same flow rate, but replaces the rigid elbow with a 1-metre-long, flexible hose fitted with its own shut-off tap.Materials and safety when handling flammable liquidsParts in contact with the medium are made of stainless steel 1.4301 (V2A) and PTFE, which are resistant to high-purity solvents. Bürkle also draws attention to the explosion protection guidelines for this pump: all parts must be earthed, and an anti-static kit is recommended for use with flammable liquids. The product page does not specify a specific ATEX certification number.Who will benefit from foot operationAnyone who fills containers from the same drum several times a day will quickly notice the difference compared to manual operation: with foot-operated control, one hand remains on the receiving container whilst the other can guide the spout or operate the shut-off valve without having to touch the pump itself. This also reduces direct hand contact with a potentially contaminated pump surface, an aspect that is particularly important when dealing with sensitive solvents.When a smaller or compressed-air-powered pump is requiredFor smaller 60-litre drums, the more compact manual pump for solvents is usually sufficient. If compressed air or inert gas is available and the immersion depth needs to remain adjustable between 60 and 95 centimetres, the solvent dispensing system with discharge elbow covers the same depth range with a complete system including a pressure regulator.Typical applicationsFilling high-purity solvents from 220-litre steel drumsWorkstations where both hands are needed to handle the target containerFrequent, repetitive filling over extended periodsDrums with G2-inch threads in laboratories, warehouses or production facilitiesTechnical detailsMaterialStainless steel 1.4301 (V2A), polytetrafluoroethylene (PTFE)Actuation typefoot-operatedPump typePressure pumpThreadG 2 inches, external threadFlow rate approx.20 l/minViscosity up to approx.500 mPa·sPipe diameter21 mmImmersion tube diameter21 mmLength of outlet bend300 mmOuter diameter of outlet13 mmMax. immersion depth95 cmFor containers up toapprox. 220 lScope of deliveryFoot-operated solvent pump with outlet elbowService and procurementThose who, in addition to stationary filling operations, occasionally need to fill containers located further away often order both the spout and the hose versions together, so that both situations are covered. LT Laborhandel can advise on choosing between the two versions, selecting the appropriate drum size and sourcing spare parts such as shut-off valves or foot pedals.
Bürkle Solvent Pump for Tinplate Canisters, V2A Stainless Steel, Bellows Seal Adapter, 5603-2000
In practice, tinplate canisters with bellows caps are often simply tipped over and emptied by hand, resulting in splashes and direct contact with the contents. The solvent pump for tin cans, on the other hand, fits a suitable threaded adapter directly onto the bellows cap and then operates like a standard hand pump based on the overpressure principle: The pump ball forces air into the canister; the excess pressure then forces the liquid out through the fixed spout.Adapter for the standard bellows capThe supplied threaded adapter, with a 35-millimetre, 2-thread internal thread, fits the bellows cap commonly used on tinplate canisters in industry. This eliminates the need for the risky manual pouring of hazardous substances; the canister remains stationary during filling, and the contents flow out in a controlled manner via the spout fitted with a shut-off valve. The adapter is screwed on once and remains attached to the canister for the duration of the transfer; afterwards, it can be removed just as easily as the original bellows cap.For canisters up to around 60 lThe pump is suitable for containers with a capacity of up to approximately 60 l; the 15-millimetre-diameter dip tube can be continuously adjusted to the depth of the canister, reaching a maximum immersion depth of 60 centimetres. With a flow rate of around 10 l per minute and a viscosity limit of up to 500 mPa·s, the performance matches that of the hand pump for drums with a G2-inch thread; only the connection itself is tailored to the canister cap.Why the adapter makes all the differenceCompared to drums with a G2-inch thread, tinplate canisters are a category of their own; the bellows cap cannot simply be converted to a standard thread. Without a suitable adapter, many businesses have no choice but to tip the canister, with all the associated risks of splashing and uncontrolled spillage. The supplied adapter bridges this gap without requiring any modifications to the canister itself, and can be removed again once filling is complete.Materials and safety when handling flammable liquidsParts in contact with the medium are made of 1.4301 (V2A) stainless steel and PTFE and are chemically resistant to organic solvents and aromatic compounds. Bürkle refers to the explosion protection guidelines when handling flammable, highly flammable liquids: all parts must be earthed; in addition, the manufacturer recommends an anti-static kit. The product page does not specify a specific ATEX certification number.If a different container is being usedFor drums with a G2-inch thread instead of a bellows seal, the identically constructed hand pump for solvents is the appropriate choice; for small containers with a GL45 connection up to 10 l, the Mini solvent pump is recommended. If, on the other hand, 220-litre steel drums need to be connected and both hands need to remain free, the foot-operated solvent pump - available in either an outlet elbow or hose version, meets this requirement.Independent of mains power and compressed airLike the other hand pumps in the range, this model requires neither a mains power connection nor a compressed air supply. This makes it particularly practical for businesses that only occasionally open tin cans, such as in smaller laboratories, workshops or storage areas without their own compressed air network. The threaded adapter can also be swapped between several canisters of the same closure type, meaning a single pump is sufficient for multiple containers.Typical applicationsContamination-free decanting from tinplate canisters with bellows closuresAvoiding the manual pouring of hazardous substancesExtraction of organic solvents and aromatic compounds in the laboratoryBusinesses that routinely source raw materials in tinplate canistersGoods-in and decanting stations where several cans with the same type of closure are in circulationTechnical detailsMaterialStainless steel 1.4301 (V2A), polytetrafluoroethylene (PTFE)Drive typemanually operatedPump typePressure pumpConnection typeThreaded, female threadConnection35 mm, 2-threadFlow rate approx.10 l/minViscosity up to approx.500 mPa·sPipe diameter15 mmImmersion tube diameter15 mmLength of outlet bend185 mmOuter diameter of outlet12 mmMax. immersion depth60 cmFor containers up toapprox. 60 lScope of deliverySolvent pump with fixed outlet elbow and shut-off valveThreaded adapter for tin cansService and procurementBusinesses that use both canisters with bellows closures and drums with G2-inch threads often order both pump versions together, so that the correct connection is available for every container.

Heidolph Hei-FLOW Core 600 Peristaltic Pump, 50 to 600 rpm, up to 4,151 Ml/min, 523-50060-00
Pumping larger volumes in a shorter time requires a drive with greater speed reserve than the 120 series offers. The Hei-FLOW Core 600 covers a speed range of 50 to 600 revolutions per minute and, with a single-channel pump head, achieves a flow rate of up to 4,151 millilitres per minute. Like all Hei-FLOW drives, it is supplied without a pump head; this is selected separately to suit the fluid being pumped.High flow rate for single-channel applicationsThe Core 600 is designed for use with single-channel pump heads, with flow rates ranging from 4.0 to 4,151 millilitres per minute. A switch reverses the flow direction, allowing the same unit to be used for both filling and emptying larger vessels. The Core 600 is not intended for multi-channel operation; the 120 series models are available for this purpose.Same drive technology, higher speedThe EC motor draws 100 watts and delivers the same power; it is digitally controlled with a control accuracy of ± 0.5 per cent according to the data sheet and a flow accuracy of ± 5 per cent. The unit is designed for continuous operation 24 hours a day, 7 days a week, and switches off automatically in the event of overheating. Weighing 7.1 kilograms, the Core 600 is slightly lighter than the 120 models in the range due to its more compact internal design; the dimensions of 166 by 225 by 256 millimetres (excluding the pump head) remain the same. This means the Core 600 can be swapped for a 120 model without requiring any additional space should a process suddenly demand higher throughput.Protection rating, noise level and connectionsProtection rating IP 54 in accordance with DIN EN 60529 and protection class 1 in accordance with EN 61140 comply with the standard for the entire Hei-FLOW range. The sound pressure level is below 55 dB(A) in accordance with IEC 61010, even at the higher speeds of the 600 series. The unit is powered by 110 to 240 volts at 50 or 60 hertz.Typical applicationsDecanting and transferring large volumes of liquidFilling and emptying of containers via reversible flowHigh-throughput processes with minimal space requirementsPilot-scale trials where the speed of the 120 series models is insufficientSelection guide: Core 600 or one of the 120 seriesThose who primarily handle smaller volumes or multiple channels in parallel are better served by the Hei-FLOW Core 120 or the Hei-FLOW Core 120 Multi; both cover 10 to 120 revolutions per minute. If the high flow rate of the 600 series is also to be controlled via an analogue interface or foot switch, the Hei-FLOW Expert 600 offers the same speed range with external connectivity. The Hei-FLOW Ultimate 600 is available for digital display, an RS232 interface and dosing functions at high throughput.Technical detailsDimensions (W x H x D)166 × 225 × 256 mm, excluding pump headWeight7.1 kg (excluding pump head)DriveEC motorSpeed range50 to 600 rpmSpeed controlDigitalSpeed displayAnalogueControl accuracy± 0.5 %Volume flow accuracy± 5 %Single-channel flow rate4.0 to 4,151 ml/minDirection of rotationclockwise / anti-clockwisePower consumption100 WMotor power100 WOperating modeContinuous operation 24 hours a day, 7 days a weekOverheating protectionYesRated voltage110 to 240 V, 50/60 HzProtection class (EN 60529)IP 54Protection class1 (EN 61140)Sound pressure level< 55 dB(A) (in accordance with IEC 61010)Scope of deliveryHei-FLOW Core 600 drive unit, order number 523-50060-00Operating instructions and Safety Guide as PDF downloadsThe pump head and tubing are not included in the Scope of delivery.

Bürkle, Mini solvent pump, 1.8 l/min, GL45 connection, #5603-4000
Mini Solvent Pump | Safe dispensing of small quantities The Mini Solvent Pump is an extremely high-quality hand pump for small containers such as bottles, canisters and containers up to approx. 10 litres. For the safe dispensing and dosing of solvents and highly flammable liquids. Simple principle – great results The hand pump operates on the overpressure principle. Pressing the pump ball builds up overpressure inside the container, which forces the liquid out. This ensures that only the hose, feed tube and spout come into contact with the liquid being dispensed. A pressure relief valve protects the solvent pump against excessive pressure build-up – for example, due to direct sunlight – ensuring safety. High-quality materials All parts of this hand pump that come into contact with the medium are made from high-quality, inert materials – PTFE and stainless steel (1.4301, 1.4404) – which are characterised by their excellent chemical resistance. The Mini solvent pump is therefore particularly well suited for use with high-purity liquids and highly flammable media, e.g. acetone, isopropanol, ethanol, methanol, etc. Filling in potentially explosive atmospheres The supplied earthing cable can be easily connected to the solvent pump via a spade connector; this dissipates electrostatic charges, allowing flammable media to be dispensed safely. Flexible in use The solvent pump can be used to fill from a wide variety of container sizes. The flexible PTFE hose, which draws the liquid from the container, can be cut to any length. This enables the container to be emptied completely, even in the case of bottles and canisters with a domed base. The hand pump has a standard GL 45 connection thread. However, with the appropriate thread adaptors (accessories), it can be easily adapted for use with containers featuring S 40, GL 38 or GL 32 thread sizes. Precise dispensing of the liquid The self-closing spout (with auto-stop function) on the Mini solvent pump enables absolutely precise dispensing, with no dripping whatsoever. Thanks to the simple dosing mechanism, even the smallest containers, such as test tubes, can be filled without any problems. A hose (internal Ø 6 mm) can be optionally attached to the spout, allowing safe filling even into containers situated further away. Perfectly balanced The Mini solvent pump is particularly compact and very well balanced, enabling tilt-free dispensing even from small containers. Robust and durable Thanks to its robust design and high-quality materials, the durable Mini solvent pump enables consistently safe and clean filling in the simplest and most convenient way. Ideal for 1–5 l containers GL 45 connection thread Parts in contact with the medium made from PTFE and stainless steel (1.4301, 1.4404) PTFE hose (6x8 mm), 0.4 m Includes 2 m earthing cable Adapters for S 40, GL 38 and GL 32 available as accessories Sterility: No

Bürkle, drum pump for concentrated acids/alkalis, 100 cm, 80 rpm, #5762-0200
Sulphuric acid, nitric acid, hydrofluoric acid and sodium hypochlorite corrode most plastics more severely than diluted acids. The drum pump for concentrated acids and alkalis is therefore of the same design as the drum pump for acids and alkalis, but has a pump body made of PVDF instead of polypropylene. Two immersion depths, 100 and 120 centimetres, are suitable for standard drums up to 220 litres.PVDF instead of polypropylene for highly corrosive mediaPolyvinylidene fluoride (PVDF) is more chemically resistant than polypropylene and makes the pump suitable for media that would, over time, corrode a pump made entirely of PP. Bürkle cites sulphuric acid, nitric acid, hydrofluoric acid and sodium hypochlorite as typical applications. This version is also expressly unsuitable for hydrochloric acid; chemical resistance must be checked before use by referring to the manufacturer’s resistance list.Electric centrifugal pump with a slightly lower flow rateAt around 80 litres per minute, the flow rate is just below that of the PP version at 85 litres per minute; the difference is due to the PVDF pump body. The 2-metre-long outlet hose and the 41-millimetre-thick immersion tube are standard features of the drum pump series.Two immersion depths for standard drumsThe 100-centimetre version and the 120-centimetre version differ solely in their immersion depth; all other technical specifications are identical for both. The immersion tube can be adjusted continuously to the actual drum depth.When the standard version is sufficientFor low-viscosity acids such as phosphoric acid, chromic acid or battery acid, where polypropylene offers sufficient chemical resistance, the drum pump for acids and alkalis is the more cost-effective choice with a slightly higher flow rate. The PVDF version is worthwhile where more concentrated or aggressive media are used.Thread and connectionLike the PP version, this pump also uses a G 1¼-inch thread for the drum connection, rather than the G 2-inch thread commonly found on other Bürkle drum pumps. It is therefore worth checking the existing drum connection before ordering to ensure the pump fits without the need for an additional adapter. The yellow colour scheme is identical for both versions in the series and allows for quick visual differentiation from the other drum pump series on the shelf.Chemical protection for operations and staffConcentrated acids and sodium hypochlorite are among the media where material failure in the pump can quickly pose a hazard to staff and the surrounding area. The PVDF pump body reduces this risk compared to a PP version, but does not replace the standard personal protective equipment or the other guidelines for handling the relevant hazardous substances in the workplace.Compatibility list as the final point of referenceEven within the group of highly corrosive acids and alkalis, there are differences in concentration that determine the actual material resistance. Before using a pump with a new medium for the first time, it is therefore advisable to consult the manufacturer’s compatibility list to avoid misjudgements between acids that sound similar but differ in their chemical corrosiveness.Electric drive for continuous pumpingEven in the concentrated version, the centrifugal pump’s electric motor runs continuously as long as the medium is flowing, rather than delivering individual strokes as with a hand pump. This is particularly suitable for businesses that regularly transfer larger quantities of a specific concentrated acid or alkali between a drum and a process vessel.Typical applicationsTransferring highly corrosive acids such as sulphuric, nitric or hydrofluoric acidDecanting sodium hypochlorite and similarly corrosive alkalisLarger transfer volumes from standard drums of up to 220 litresOperations where polypropylene is not chemically suitable as a pump materialTechnical detailsConnection typeDrum connectionThreadG 1 1/4 inch, external threadFlow rate approx.80 l/minViscosity up to approx.500 mPa·sImmersion tube Ø41 mmColouryellowLength of outlet hose2 mFor containers up toapprox. 220 lDrive typeelectricPump typeCentrifugal pumpImmersion depth adjustmentInfinitely adjustableMaterialPolyvinylidene fluoride (PVDF), polypropylene (PP)Overview of variantsItem numberMax. immersion depth5762-0200100 cm5762-0201120 cmScope of deliveryDrum pump for concentrated acids/alkalis at the selected immersion depthRegulatory informationThe drum pump for concentrated acids/alkalis is an electrical appliance within the meaning of the ElektroG. Information on returns can be found under ‘Environment and Disposal’.Service and procurementFor low-viscosity, less corrosive acids, the drum pump for acids and alkalis with a PP pump body is often sufficient. For smaller quantities without a mains power supply, the Ultrarein PTFE drum pump is a manually operated alternative. LT Laborhandel stocks both immersion depths separately and can advise on the appropriate choice based on the medium to be transferred.
IKA VACSTAR control Diaphragm Vacuum Pump with Integrated Controller, 22 l/min, 0020109375
The IKA VACSTAR control (MPN 0020109375) is a dry, oil-free 4-chamber diaphragm vacuum pump with a factory-integrated vacuum controller. Anyone who has so far operated a separate pump and an additional vacuum controller side by side saves bench space and wiring effort with this 1:1 concept: the control electronics are already in the pump housing, and it is operated via a detachable display that can also be read and operated directly at the fume hood. For recurring distillation routines, for example on a rotary evaporator in routine operation, the separate wiring and calibration of an external controller for each setup is no longer necessary, which makes it easier to switch between several workstations in the laboratory. Integrated controller instead of a separate vacuum regulator The pumping capacity of 22 l/min (1.32 m³/h) and an ultimate vacuum of 2 mbar reliably cover typical tasks such as rotary evaporators, drying ovens or vacuum filtrations. The speed range extends from 285 to 1200 revolutions per minute, regulated by a ceramic Al2O3 vacuum sensor. Unlike with a plain diaphragm pump, the question of which external controller is suitable no longer arises, because the pump and control unit are already matched to each other. WiCo remote control for operation under the fume hood The TFT display of the WiCo remote control can be detached from the pump and placed separately, for example directly at the fume hood window, while the pump itself stands underneath or beside it and therefore does not have to be operated constantly through the front window. Several operating modes can be selected via the menu: automatic operation with boiling point detection and a stored solvent library, manual operation at a fixed speed, and separate pump-down and cleaning functions. The automatic boiling point detection helps to avoid bumping and to protect samples from loss through pumping down too quickly, especially with low-boiling solvents. Chemically resistant and designed for continuous operation The PTFE diaphragms and chemically resistant materials in the media path make the VACSTAR control robust against aggressive solvent vapours. An integrated valve cleaning function removes solvent residues from the system and thereby extends the service life of the diaphragms, without the pump having to be dismantled for manual cleaning. For the protection of laboratory air and the environment, the VSE 1 emission condenser can be connected afterwards, so that solvent vapours do not enter the room air unfiltered. As the pump works as a dry-running pump, oil changes are also eliminated, and with them the risk of oil vapours coming into contact with the sample. Connection and format for fixed laboratory workstations With dimensions of 270 x 435 x 500 millimetres and a weight of 14 kilograms, the VACSTAR control is designed for a fixed place at the workstation, for example directly under the fume hood bench, rather than for frequent transport between workstations. Data connection is via USB and RS232, for example for process documentation with laboratory software. The housing is classified IP 20, the device power consumption is 140 watts in operation and 1.5 watts in standby, and the pump is connected to 100 to 240 volts at 50 or 60 hertz, which allows worldwide use without a separate voltage converter. Reproducible processes thanks to automatic boiling point detection The stored solvent library automatically recognises common solvents from their boiling behaviour and adjusts the vacuum accordingly, instead of the target speed having to be readjusted manually. This reduces the variation between individual distillations and makes it easier to hand a process over to changing laboratory staff, because the parameters can be documented and repeated on the device. In combination with the USB or RS232 connection to laboratory software, the complete course of the process can also be logged, which means a noticeable time saving compared with a manually kept process file, especially in quality-assured environments with batch documentation. Typical applications As a 1:1 vacuum solution with integrated controller, the VACSTAR control is particularly suitable for the following applications: Automated distillations on the rotary evaporator with boiling point detection, also with changing solvents Vacuum drying in drying ovens with reproducible, documented process parameters Vacuum filtration where documented, repeatable process control is also required Laboratory workstations with limited space where a separate vacuum controller does not fit Process documentation via USB or RS232 in quality-assured laboratory environments Fixed vacuum workstations where several users are to run the same process reproducibly Technical details Pump type4-chamber diaphragm vacuum pump, dry, with integrated controller Pumping speed max.22 l/min (1.32 m³/h) Ultimate pressure2 mbar Inlet pressure1 to 1030 mbar Speed range285 to 1200 rpm Number of cylinders4 Connection diameter suction/pressure side8 mm Vacuum sensorCeramic (Al2O3) Controller / operationIntegrated, detachable WiCo display with touch operation Operating modesAutomatic with boiling point detection, manual operation, pump-down and cleaning function InterfacesUSB, RS232 Protection class according to DIN EN 60529IP 20 Dimensions (W x H x D)270 x 435 x 500 mm Weight14 kg Voltage / frequency100 to 240 V, 50/60 Hz Device power consumption140 W (standby 1.5 W) Scope of delivery 1 x IKA VACSTAR control Vacuum Pump with Integrated Controller 1 x WiCo remote control WH11 (detachable control unit) 1 x power supply OS 1.0 for the WiCo remote control 1 x vacuum hose (1 m) 1 x USB cable (USB-A to Micro-B, 2 m) 1 x USB cable (USB-A to USB-B) 1 x screwdriver Individual requirements & procurement service For additional protection of laboratory air and the environment, the VSE 1 emission condenser can be retrofitted, as can a Woulff bottle to protect the pump from liquid surges or suitable connecting hoses for your rotary evaporator.

Bürkle, EnergyOne mains-powered drum pump with spout, 50 cm, #5900-2050
At a fixed dispensing station where small quantities of cleaning agent or diluted acid are repeatedly drawn from canisters throughout the day, one thing is paramount: the pump must not stop because the battery has run flat. The EnergyOne is the mains-powered version of the centrifugal pump for small quantities; connected via a 230 V mains adaptor, it is ready for continuous use without any charging time.Mains operation without charging breaksPower is supplied via a 230 V mains adaptor. International plug adaptors for the EU, UK, US and AU are included, ensuring the pump is ready for immediate use even at locations with different plug types. There is no charging time whatsoever, unlike with the battery-powered model; the pump runs as long as it is connected to the mains.When mains operation is worthwhileAt a fixed workstation with a socket within reach, the EnergyOne eliminates any need to worry about the battery charge level. Particularly during frequent, closely spaced filling operations throughout the day, this brings greater peace of mind to the workflow than having to change the battery in between.Same drive system as the AccuOneThe pump unit and drive of the EnergyOne are identical in construction to those of the battery-powered AccuOne; the mains adaptor and battery can be interchanged between the two devices. If you need to use the pump in different locations without a power socket – for example, in another part of the building – the AccuOne is the better choice.Performance data for small volumesAs with the AccuOne, the flow rate ranges from 0 to around 12 l/min at a delivery head of approximately 4 mWS. The 25 mm diameter immersion tube can be adjusted continuously; the outlet elbow has an external diameter of 16 mm and a length of 203 mm. The pump is suitable for low-viscosity to aqueous acids, alkalis, chemicals and cleaning agents up to approximately 200 mPas.Materials for aggressive mediaAs with the AccuOne, the parts in contact with the medium are made of polypropylene (PP), polytetrafluoroethylene (PTFE) and Hastelloy 2.4610 (AISI Alloy C-4). The IP 20 protection rating is designed for indoor use.Three immersion depths for different containersThe version with a 50 cm immersion depth is suitable for containers up to approximately 30 litres. The 70 cm version is suitable for containers up to approximately 60 litres, whilst the 100 cm version is suitable for drums up to approximately 220 litres.Permanent installation at the filling stationAs there is no need to change or charge a battery, the EnergyOne is particularly suitable for a fixed installation at a filling or dosing station where the pump is used several times a day. The international plug adaptors make installation straightforward even at locations outside Germany.Contents of the package and connectionThe scope of delivery includes the pump unit, the drive, the mains adaptor with plug, three plug adaptors and the fixed outlet elbow. Once connected to the mains socket, the pump is ready for use without any further preparation; there is no need to charge or replace a battery.Protection class and operating environmentThe IP 20 protection rating indicates that the pump is designed for indoor use, without any special protection against water jets or dust from outside. This is sufficient for use in warehouses and laboratories with a normal indoor environment.Typical applicationsFixed filling and dosing stations with a permanent mains connectionDecanting and transferring small quantities of acids, alkalis, chemicals and cleaning agentsUse abroad thanks to plug adaptors for the EU, UK, US and AUSmall quantities in laboratory settingsTechnical detailsPump typeCentrifugal pumpDrive typeElectric (mains), 230 VFlow rate0 to 12 l/minHead approx.4 mWSViscosity up to approx.200 mPa·sImmersion tube diameter25 mm, infinitely adjustableSpout typeSpout, 203 mm, external Ø 16 mmPlugEU, UK, US, AUProtection classIP 20Materials (in contact with the medium)Polypropylene (PP), polytetrafluoroethylene (PTFE), Hastelloy 2.4610ColourgreyOverview of variantsItem numberMax. immersion depthFor tanks up to5900-205050 cmapprox. 30 litres5900–207070 cmapprox. 60 litres5900-2100100 cmapprox. 220 litresContents of deliveryPump unitDriveMains adaptor with plug3x plug adaptorsFixed outlet elbowRegulatory informationThe EnergyOne is an electrical appliance within the meaning of the ElektroG.

Bürkle, dispensing system for solvent outlet elbow, 60 cm, #5603-5001
To transfer solvents from a steel drum or canister, a system is required that does not involve handling the liquid in the open. The solvent transfer system with an outlet elbow operates using compressed air or an inert gas such as nitrogen. The gas pressure forces the liquid upwards through the dip tube and through the fixed outlet elbow into the receiving container. Two immersion depths, 60 and 95 centimetres, cater for canisters and standard drums up to 220 litres.Compressed air or inert gas instead of a motorInstead of an electric or manually operated drive, the system uses pure compressed air or an inert gas. This also makes it suitable for high-purity liquids, where a motor-driven pump would be undesirable. A supplied pressure regulator adjusts the delivery pressure; the flow rate is around 10 litres per minute, and the viscosity of the medium may be up to approximately 500 mPa·s. Three adaptors for the pressure supply (G 1/4 inch) included in the scope of delivery cater for different compressors and gas cylinders.Fixed outlet elbow for a fixed workstationThe outlet elbow is rigidly mounted and is suitable when the receiving container is positioned directly beneath or next to the drum, for example when filling laboratory bottles at a fixed workstation. According to Bürkle, the outlet elbow and outlet hose are interchangeable, meaning that the same basic system can be retrofitted with a flexible hose if required.Two immersion depths for different container sizesThe 60-centimetre version is designed for canisters and smaller drums up to approximately 60 litres; the dip tube has a diameter of 15 millimetres. The 95-centimetre version, with a 21-millimetre immersion tube diameter, is suitable for standard 220-litre drums. In both cases, the immersion tube can be continuously adjusted to the actual drum depth, ensuring that it does not rest on the drum base and that the final residual quantity cannot be reached.Safety when handling flammable solventsBürkle expressly points out that the pump and pressure regulator must be earthed and that an anti-static kit must also be used when decanting flammable or highly flammable solvents. The system can be used with UN containers and drums with a test pressure of at least 150 kPa. A grounding cable for the pressure regulator unit is included in the scope of delivery, as is a transport stand that keeps the system stable even when not positioned directly next to the drum.Compact system with accessories for mobile useThe transport stand supplied holds the pressure regulator unit and connecting hose together when the system is moved between different drums or workstations. Two protective plugs seal the connections during transport or when the system is not in use, preventing any medium from dripping out or dirt from entering. Bürkle also marks the system with a pictogram indicating suitability for food contact, without specifically referring to a particular standard such as EU 1935/2004. It is therefore advisable to consult the manufacturer for final approval in food-contact applications.Typical areas of applicationDecanting solvents from drums and canisters into smaller containersDirect dispensing at the point of use in laboratories or chemical productionFilling of high-purity liquids without a motorised pumpUse with UN containers and drums from a test pressure of 150 kPaTechnical detailsConnection typeDrum screw connectionThreadG 2 inch, external threadFlow rate approx.10 l/minViscosity up to approx.500 mPa·sOutlet typeElbow outletDrive typepneumatic (compressed air or inert gas)Pump typePositive displacement pumpAdjust immersion depthInfinitely adjustableMaterialV2A stainless steel (1.4301), PTFE inner parts of the immersion tubeOverview of variantsItem numberMax. immersion depthFor vessels up toImmersion tube ØLength of outlet bendOuter outlet diameter5603-500160 cmapprox. 60 l15 mm185 mm12 mm5603-500395 cmapprox. 220 l21 mm280 mm13 mmContentsSolvent pump with outlet elbowPressure regulator unitTransport stand2x protective plugsEarthing cable for pressure regulatorConnecting hoseKey for pressure supply3x pressure supply adaptors (G 1/4 inch)Service and procurementThe appropriate immersion depth depends on the drum size at the workplace. For smaller canisters up to 10 litres with a GL45 connection, the Mini solvent pump is often the more practical choice; for simple manual operation without a compressed air connection, the manual solvent pump is recommended. When dealing with particularly pure media in a manually operated version, the Ultrarein PTFE drum pump is more suitable. LT Laborhandel stocks both versions of the dispensing system separately and can advise on selecting the appropriate immersion depth and pressure supply.
Bürkle, Petro electric drum pump, with standard dispensing nozzle, #5780-0040
A depot that regularly transfers diesel from a 200-litre drum into vehicles or EL heating oil into a tank needs a pump that does not have to be operated manually every time it is used. The Petro electric drum pump does exactly that: it dispenses diesel, EL heating oil, undiluted radiator antifreeze and other liquids classified as hazard class AIII (VbF) via a dispensing nozzle, powered by a 230 V mains socket.Over-lift protection against leaksAn integrated anti-lift protection system interrupts the flow if the hose is damaged or breaks off, thereby preventing fuel from leaking uncontrollably. This is an essential safety feature for daily use on vehicles and machinery.Standard or automatic dispensing nozzleThe pump is available with two types of nozzle. The standard nozzle is switched off manually and delivers a flow rate of around 38 l/min. The self-shutting-off automatic nozzle stops automatically as soon as the target tank is full – which is practical for frequent refuelling without constant supervision – and has a flow rate of around 32 l/min. Which variant is more suitable depends on whether a person is supervising the refuelling process throughout or is carrying out other tasks at the same time.Reach and connectionWith a submersion depth of 160 cm, the pump can reach the bottom of a 220-litre drum. The 4-metre-long outlet hose bridges the distance to the receiving container, whilst the suction head is approximately 2 metres water column. The connection is via an M 64x4 external thread, suitable for standard drum openings.Not suitable for liquids containing waterThe pump is expressly not suitable for liquids containing water or diluted liquids. Anyone who needs to transfer aqueous media as well as fuels will require a second, suitable pump unit for this purpose.Flow meter as an accessoryFor businesses wishing to document dispensed volumes, an electronic flow meter with totaliser and calibration facility is available as an accessory. The meter is uncalibrated and is therefore suitable for internal volume monitoring, but not for billing purposes subject to legal metrological requirements.Use in everyday workshop operationsWhether refuelling construction machinery in the yard, topping up EL heating oil in the fuel storage room or transferring radiator antifreeze in the workshop: the pump remains mounted on its stand and is immediately ready for use via the dispensing nozzle, without having to fetch a separate unit for every task.Electric drive instead of a hand-operated pumpCompared to a hand-operated pump, the electric drive eliminates the need for repeated manual pumping – a noticeable difference, particularly when refuelling several times a day. The operator simply holds the nozzle; the pump itself handles the delivery via the electric motor.Threaded connection instead of hose connectionThe connection via the M 64x4 external thread sits securely on the drum and prevents slipping during operation, unlike a simple push-fit connection. The thread fits standard 200-litre drums, such as those commonly used for diesel and EL heating oil.Limitations of useThe pump is the right choice for fuels and mineral oils, but it is expressly not suitable for acids, alkalis or other chemicals. Anyone transferring both types of medium in the same facility will need two separate pumps to ensure that no residual medium enters the other application.Typical applicationsRefuelling vehicles and machinery with diesel from a storage drumTransferring EL heating oil into tanksPumping undiluted radiator antifreezeDepots, workshops and warehouses with regular fuel handlingTechnical detailsPump typeCentrifugal pumpDrive typeelectric, 230 VMax. immersion depth160 cmLength of outlet hose4 mSuction height approx.2 mWSConnection typeThread, M 64x4 external threadFor tanks up toapprox. 220 litresColourgreyOverview of variantsItem numberFuel nozzleFlow rate approx.5780-0040Standard (manual)38 l/min5780-0041Automatic (self-shutting)32 l/minContentsPetro electric drum pump with the selected dispensing nozzleThe electronic flow meter is not included and must be ordered separately.Regulatory informationThe Petro electric drum pump is an electrical appliance within the meaning of the ElektroG.

Bürkle Gas-tight PP Barrel Pump, 2 X 3/4-inch Threaded Adaptors, Telescopic Immersion Tube 40 to 67 cm, 5610-1040
Two 3/4-inch threaded adaptors with lock nuts distinguish the Bürkle 5610-1040 barrel pump from its sister model: the hose connection on the dispensing container is securely screwed in place. The pump itself is a hand-operated reciprocating piston pump made of PP with a gas vent line, which delivers 220 ml per stroke. The telescopic tube extends continuously to a depth of between 40 and 67 cm into the container, and the outlet hose is 1.2 m long.Tightly screwed connection with 3/4-inch adaptorsThe adaptors with lock nuts are designed for openings from 28 mm; a universal plug for openings from 34 to 70 mm is included for the original container. This variant is useful if you do not want the hose connection on the container to consist of a plug. Those who prefer the flexibility to switch between different opening sizes should take a look at the 5610-1030 drum pump with a variable universal plug.Gas and liquid linesGas recirculation takes place via the gas recirculation line; the gas and liquid lines each have a shut-off valve. Bürkle intends the pump for the low-odour transfer of volatile, strong-smelling or harmful liquids, such as strongly odourous substances like ammonia, as well as acids and alkalis. For acids and alkalis, the resistance of the materials PP, PE and PVC is crucial; the outlet hose is made of soft PVC.Displacement volume and dip tubeThe pump dispenses 220 ml per stroke. The dip tube has a diameter of 32 mm, whilst the tube above it is 22 mm in diameter. As the telescopic tube can be extended continuously from 40 to 67 cm, the pump is suitable for drums and canisters of various heights. The handle is attached to the piston.Not suitable for flammable liquidsThe instructions for use explicitly exclude the filling of flammable liquids. The material is non-conductive. For handling acids, alkalis or liquids harmful to health, the SafetyBox 2507-9000 from Bürkle is available, complete with safety goggles and protective gloves.Operating limitationsPumping is carried out manually; continuous operation is not intended. The permissible temperature range is 0 to 40 °C, and the unit is for indoor use only. Contaminated fluids are not permitted, and the pump is not dishwasher-safe. When the piston is extended, it requires space above the container plus 20 cm. No maintenance is required.Typical applicationsThe 5610-1040 is suitable for tasks where the filling container is connected via a screw-on hose connection:Decanting strongly odourous substances such as ammoniaFilling with volatile or hazardous liquids in laboratories, production facilities and warehousesAcids and alkalis from drums and canisters, provided PP, PE and PVC are compatiblePermanently screwed hose connection to the filling container (3/4 inch)Technical detailsConnection optionsTwo 3/4-inch threaded adaptors with lock nuts for the filling container (openings from 28 mm), universal plugs 34 to 70 mm for the original containerPump typeReciprocating piston pump, hand-operated, not suitable for continuous useFlow rate220 ml per strokeTube diameter22 mmImmersion tube diameter32 mmImmersion depth40 to 67 cm, infinitely adjustableOutlet1.2 m outlet hose with shut-off valveGas returnGas supply line, gas and liquid lines, each with a shut-off valveMaterialsPP, PE, PVCColourgrey/blueOperating temperature0 to 40 °CLimitationsNot suitable for flammable liquids, for indoor use only, not suitable for contaminated media, not dishwasher-safePackaging unit1 pieceScope of deliveryGas-tight PP drum pump with infinitely extendable telescopic dip tube (40 to 67 cm) and reciprocating piston with handle1.2 m outlet hose with shut-off valveGas supply line with shut-off valvePlug for the original containerTwo 3/4-inch threaded adaptors with lock nuts for the dispensing containerInstructions for useFrequently asked questionsIs the pump approved for use with flammable liquids?

Bürkle, AirJet Mini diaphragm vacuum pump/compressor, EPDM, #5625-2000
A laboratory that requires a brief period of negative pressure for filtration, followed shortly afterwards by a slight positive pressure for a small dosing line, often relies on two separate units. The AirJet Mini handles both tasks with a single, compact diaphragm pump. It pumps, compresses and evacuates completely oil-free, without altering or contaminating the pumped medium.Dry-running and oil-freeThe diaphragm operates dry; there is no oil bath whatsoever, unlike in conventional rotary vane pumps. As a result, the air or gas being pumped does not pick up any traces of oil, and the pump itself does not require an oil change. The housing is made of polyphenylene sulphide (PPS), a chemically resistant high-performance plastic that remains stable even with frequent contact with neutral to slightly aggressive gases and vapours.Vacuum pump and compressor in a single unitDepending on which side of the pump is connected, the AirJet Mini operates as either a vacuum pump or a compressor. Via the suction side, it evacuates containers or filtration set-ups; via the discharge side, it delivers and compresses air or gas for dosing and purging tasks. A second unit for the other function is not required.Two diaphragm materials for different mediaThe diaphragm is available in two versions. The version with an EPDM diaphragm is intended for general use with neutral gases and vapours; it has a flow rate of around 6 l/min. The PTFE-coated diaphragm is suitable for slightly aggressive or corrosive gases and vapours; its flow rate is slightly lower at around 5 l/min. The appropriate version depends on the medium being handled, not on the required flow rate.Compact design for the laboratory workbenchMeasuring 164 mm in length, 90 mm in width and 141 mm in height, the AirJet Mini can still find a place even on a well-equipped laboratory workbench. It is connected via a 4 mm hose nozzle, compatible with standard laboratory hose materials.Low-maintenance operationAs no oil is involved, the typical maintenance steps required for an oil-lubricated pump are eliminated: no oil changes, no checking of the oil level, and no disposal of waste oil. This significantly reduces maintenance requirements over the pump’s service life, particularly when the pump switches between vacuum and pressure operation several times a day.What tasks is the AirJet Mini suitable for?It is typically used wherever small volumes of air or gas need to be moved without oil or other contaminants entering the system. This applies equally to evacuating a desiccator as it does to aerating a dosing line, where a clean, dry medium is essential.Selecting the right diaphragmFor neutral gases and vapours, the EPDM diaphragm is the obvious choice, as it covers most standard applications. Where slightly aggressive or corrosive gases and vapours are involved – for example, near chemical storage areas or during cleaning processes – the PTFE-coated diaphragm is the more resistant option. Where in doubt, the deciding factor is chemical resistance to the specific medium, not the slight difference in flow rate between the two versions.Connection to existing laboratory set-upsThe 4 mm hose nozzle allows the AirJet Mini to be connected to existing set-ups using standard laboratory hoses, such as a filter funnel, a desiccator or a small dosing line. It is possible to switch between the suction and pressure sides using the same hose connection without having to modify the unit.Typical applicationsEvacuating containers and filtration set-upsConveying and compressing air for dosing and flushing linesHandling neutral to slightly aggressive or corrosive gases and vapoursLaboratory workstations with varying requirements for negative and positive pressureTechnical detailsConnection typeHose nozzleConnection diameter4 mmLength164 mmWidth90 mmHeight141 mmDrive typeelectricHousing materialPolyphenylene sulphide (PPS)Overview of variantsItem numberDiaphragmFlow rate approx.5625-2000EPDM6 l/min5625-2001PTFE5 l/minScope of deliveryAirJet Mini diaphragm vacuum pump/compressor in the selected diaphragm versionRegulatory informationThe AirJet Mini is an electrical appliance within the meaning of the ElektroG. Information on the return of end-of-life equipment can be found under ‘Environment and Disposal’.Service and procurementWhich diaphragm version is suitable for a particular medium depends on its chemical composition. LT Laborhandel supplies both variants of the AirJet Mini individually and, if required, can also advise on combining them with other Bürkle pumps – for example, if the same facility needs to transfer not only gases but also liquids from canisters or drums, using, for instance, the mains-powered electric laboratory pump or the battery-operated drum pumps from the AccuOne range for small quantities. If you have any queries regarding the appropriate diaphragm or the configuration of multiple Bürkle pumps, please contact LT Laborhandel for assistance.
IKA MVP 10 basic Vacuum Pump, Oil-Free Diaphragm Pump, IP 54, 0003980000
The IKA MVP 10 basic (MPN 0003980000) is a compact, oil-free diaphragm vacuum pump for straightforward laboratory use. Without a display, without digital interfaces and without a controller, the unit concentrates on pure function: reliably generating vacuum, robustly built and easy to maintain. This makes the MVP 10 basic a pragmatic choice for workstations where a simple vacuum source is needed without control software or a process log behind it, for example as a second or third pump for less critical secondary tasks alongside a precisely controlled main setup. Two-stage pump with solid delivery rate The two-stage, two-cylinder diaphragm pump reaches a maximum delivery rate of 1.7 cubic metres per hour (28.3 litres per minute). The ultimate pressure is 7 mbar without gas ballast and 15 mbar with the gas ballast valve activated. The gas ballast valve is particularly helpful when moist or solvent-containing vapours arise during pumping, as it prevents them from condensing in the pump and attacking the diaphragms in the long term. The permissible inlet pressure ranges from 7 to 1050 mbar, so the pump is suitable both for initial evacuation and for maintaining an existing vacuum. Chemical resistance through PTFE components throughout All parts in contact with gas are made of PTFE or PTFE compounds, which makes the MVP 10 basic particularly resistant to aggressive chemicals. Combined with the dry, oil-free design, oil changes and the disposal of waste oil are eliminated entirely, and at the same time the risk of sample contamination by oil vapours drops to zero. The flat, compact design and the construction built for durability ensure a high ease of servicing in everyday laboratory work, so that maintenance can generally be carried out quickly and without special tools. Protection class IP 54 for harsh operating conditions With protection class IP 54 according to DIN EN 60529, the MVP 10 basic is dust-proof and splash-proof and is therefore more robustly designed than many comparable laboratory vacuum pumps without this classification, for example the VACSTAR series with only IP 20. This also makes it interesting for locations where liquids are occasionally handled or the ambient air is not dust-free, for example in pilot plants or workshop laboratories. The permissible ambient temperature is between 10 and 40 degrees Celsius at a maximum permissible relative humidity of 80 percent, which also allows use in rooms that are less strictly air-conditioned. Compact format for fixed workstations With dimensions of 245 x 155 x 320 millimetres and a weight of 11.5 kilograms, the MVP 10 basic takes up little space and can also be moved between several workstations if required. The connection is made via 10 millimetre hose nozzles on the suction and pressure side, and the speed is constant at 1380 revolutions per minute in 50 hertz operation and 1680 revolutions per minute at 60 hertz, without any need for manual speed control. The pump is connected to 230 volts at 50 or 60 hertz with a device power consumption of 180 watts. Deliberate omission of display and interfaces Unlike the VACSTAR series, the MVP 10 basic deliberately dispenses with a display, digital interfaces and a vacuum controller. This reduces not only the purchase price but also the number of potential sources of error and wearing parts that would have to be replaced in the event of service. For applications that do not require finely regulated, documented process control but simply need a reliable vacuum, this is a deliberate and sensible compromise in favour of robustness, easy maintenance and a clearly calculable purchase. Typical applications As a robust, easy-to-operate entry-level pump without additional electronics, the MVP 10 basic is particularly suitable for the following applications: Simple vacuum filtrations in the routine laboratory where a finely regulated, digitally traceable ultimate vacuum depth is not required Suction and evacuation in pilot plants or workshop laboratories with a rougher, less air-conditioned ambient climate Support of desiccators and simple drying setups in routine operation Fixed workstations with several users where a reliable, robust vacuum source without its own user interface is sufficient Teaching laboratories where a robust, easy-to-explain pump with no significant operating effort is required Technical details Pump type2-cylinder diaphragm vacuum pump, dry, two-stage Delivery rate max.

Bürkle, AccuOne battery-powered drum pump with spout, 50 cm 5900-1050
Anyone who needs to draw cleaning solutions or diluted acids several times a day from different containers – often in places where there is no nearby power socket – will benefit from a cordless pump. The AccuOne is a battery-powered centrifugal pump for small volumes, designed to deliver low-viscosity to aqueous acids, alkalis, chemicals and cleaning agents up to approximately 200 mPas, without the need for a power socket.Lithium-ion battery with no memory effectThe battery is lightweight, powerful and has no memory effect, so recharging it mid-use does not reduce its subsequent runtime. An auto-stop function protects against deep discharge. According to Bürkle, a full charge is sufficient for a flow rate of around 1,500 litres, with a charging time of approximately 4 hours. The plugs are designed for use in the EU and the UK.Hybrid system with mains power supplyThe AccuOne’s drive and pump unit can also be operated using a mains power supply. The identically constructed EnergyOne, which runs on mains power, is available as a standalone product from LT Laborhandel; the battery and mains power supply are interchangeable. Those who mainly use the pump at a fixed workstation with a mains socket and do not wish to wait for the battery to charge are often better served by the EnergyOne.Performance data for small volumesThe flow rate ranges from 0 to around 12 l/min, whilst the head is approximately 4 mWS. The 25 mm diameter immersion tube can be continuously adjusted in terms of immersion depth and fits through container openings from 25 mm. The connection is via a drum coupling; the outlet elbow has an external diameter of 16 mm and a length of 203 mm. The IP 20 protection rating is designed for indoor use.Materials for aggressive mediaThe parts in contact with the medium are made of polypropylene (PP), polytetrafluoroethylene (PTFE) and Hastelloy 2.4610 (AISI Alloy C-4), three materials with high chemical resistance. Before use with a specific medium, however, it is still worth consulting a chemical resistance table, as Bürkle itself recommends on the product page.Three immersion depths for different containersThe shortest version, with a 50 cm immersion depth, is suitable for containers up to approximately 30 litres. The medium version, with a 70 cm immersion depth, is suitable for containers up to approximately 60 litres, whilst the longest version, with a 100 cm immersion depth, is suitable for drums up to approximately 220 litres.Mobile use without a power cableAs it has no mains cable, the pump can be taken between different locations – for example, if several canisters need to be emptied in different storage areas in the course of a morning. The lithium-ion battery can be swapped for a charged spare battery in just a few simple steps.Contents of the pack and initial set-upThe scope of delivery includes the pump unit, drive unit, battery, charger with plug, a plug adapter set and the fixed outlet elbow. Before first use, charge the battery using the supplied charger; the pump is then ready for immediate use.Protection rating and operating environmentThe IP 20 protection rating indicates that the pump is designed for indoor use, without any special protection against water jets or dust from outside. This is sufficient for use in warehouses and laboratories with a normal indoor environment.Typical applicationsDecanting and transferring small quantities of acids, alkalis, chemicals and cleaning agentsMobile use at different workstations without a nearby power socketRegular filling of containers with narrow openingsSmall quantities in laboratory settingsTechnical detailsPump typeCentrifugal pumpDrive typeElectric (battery-powered)Flow rate0 to 12 l/minHead approx.4 mWSViscosity up to approx.200 mPa·sImmersion tube diameter25 mm, infinitely adjustableFor openings from25 mmConnection typeBarrel screw connectionOutlet typeSpout, 203 mm, 16 mm external diameterBattery charging time approx.4 hoursPlugEU, UKProtection classIP 20Materials (in contact with the medium)Polypropylene (PP), polytetrafluoroethylene (PTFE), Hastelloy 2.4610ColourgreyOverview of variantsItem numberMax. immersion depthFor tanks up to5900-105050 cmapprox. 30 litres5900–107070 cmapprox. 60 litres5900-1100100 cmapprox. 220 litresContents of deliveryPump unitDriveBatteryCharger with plugPlug adapterFixed outlet elbowRegulatory informationThe AccuOne is an electrical appliance within the meaning of the ElektroG.

Bürkle, gas-tight V2A drum pump with hose, depth 91 cm, #5611-0090
It is difficult to transfer outgassing or strongly odourous substances using an open drum pump without odours or vapours escaping. The V2A gas-tight drum pump returns the displaced vapours to the original container via a vapour recovery system using the vapour recirculation method, rather than releasing them into the workspace. The pump body is made of V2A stainless steel and PTFE; two immersion depths of 57 and 91 centimetres cater for drums up to 220 litres.Gas recirculation using the gas swing methodWhen filling the receiving vessel, the inflowing liquid displaces air and vapours from the container. The Gas-Tight V2A Drum Pump returns these vapours to the original container via a vapour recirculation line, rather than releasing them into the surrounding environment. This reduces workplace exposure to solvent vapours and protects against odour nuisance in the case of strongly odourous media.Two ball valves for a hermetically sealed systemA shut-off system comprising two ball valves hermetically seals the flow paths when the pump is not in operation. In combination with the universal adapter, which fits container openings from 16 to 49 millimetres, the system can be connected to various types of drums and canisters without vapours escaping from the connection.V2A stainless steel instead of plasticWhilst the structurally identical ‘Gasdicht’ drum pump in PP design is sufficient for media compatible with plastic, the V2A version made of 1.4301 stainless steel with PTFE internal parts offers greater mechanical robustness and is also suitable for media that would corrode plastic. However, Bürkle expressly warns against using the pump with acetone or similarly dehydrating solvents.Safety and earthingWhen handling flammable, highly flammable liquids, Bürkle states that explosion protection guidelines must be observed; all parts must be earthed and an anti-static kit must also be used. The immersion depth can be continuously adjusted to the actual drum depth for both sizes.Two sizes for different drumsThe 57-centimetre version is designed for smaller drums up to approximately 60 litres and delivers around 330 millilitres per stroke. The 91-centimetre version is suitable for standard 220-litre drums and delivers significantly more per pump stroke – around 540 millilitres – because the longer dip tube covers a greater distance. The same universal adapter is used for both sizes, so changing the drum size does not require an additional adapter.Differences compared to the open drum pumps in the rangeMost other drum pumps in the range, such as the Ultrarein PTFE drum pump, release vapours into the surrounding environment during dispensing, which is not a problem for odourless or non-critical media. Only when odour nuisance, health and safety or emission regulations come into play is the additional cost of a gas-tight system with vapour recovery justified. For media where neither vapour recirculation nor stainless steel is required, a simpler design is often sufficient.Maintenance of ball valves and sealsThe two ball valves and the seals on the adapter connections are the points where a gas-tight system is most likely to fail. Regular checks for leaks, particularly after switching between different container openings, ensure that the gas recirculation system remains reliable and prevents vapours from escaping unnoticed into the environment.Typical areas of applicationDecanting outgassing or strong-odour media in laboratories, production facilities and warehousesBusinesses prioritising emission control and health and safety at the decanting stationConnection to various container openings ranging from 16 to 49 millimetresDecanting from smaller and larger drums, depending on the selected immersion depthTechnical detailsConnection typeDrum couplingThreadG 2 inches, external threadViscosity up to approx.500 mPa·sImmersion tube diameter32 mmColoursilverOuter diameter of spout15 mmLength of outlet hose1 mSpout typeSpout hoseFor openings16 to 49 mm (universal adapter)Operating methodManually operatedPump typeReciprocating piston pumpSpecial featuresGas recirculation via gas recirculation line, 2 ball valvesMaterialV2A stainless steel (1.4301), polytetrafluoroethylene (PTFE)Overview of variantsItem numberMax. immersion depthFlow rate approx.For tanks up to5611-109057 cm330 ml/strokeapprox. 60 l5611-009091 cm540 ml per strokeapprox. 220 lContentsGas-tight stainless steel drum pump with outlet hose at the selected immersion depthService and procurementIf a plastic-compatible medium is sufficient, the gas-tight PP drum pump is the lighter and more cost-effective alternative, operating on the same principle. For high-purity media without gas recirculation, the ultra-pure PTFE drum pump is more suitable. LT Laborhandel stocks both immersion depths separately and can advise on the selection based on the drum size and the medium to be transferred.
Bürkle, Ultrarein PTFE drum pump with spout, 40 cm, #5606-0400
Acids, alkalis and other media that corrode polypropylene or PVC require a pump made from an even more resistant material. The Ultrarein PTFE drum pump with outlet elbow is a hand-operated reciprocating piston pump whose parts in contact with the medium are made entirely of PTFE and FEP; it is highly chemically resistant and also suitable for ultra-pure liquids. Three immersion depths ranging from 40 to 95 centimetres cater for canisters and drums up to 220 litres.PTFE and FEP materials for aggressive mediaAccording to Bürkle, PTFE and FEP resist almost all aggressive chemicals with the exception of elemental fluorine, even in applications where polypropylene or PVC would be corroded. This makes the pump a suitable option for acids and alkalis as well as for high-purity liquids in analytical applications, where metal or plastic abrasion from the pump could contaminate the sample.Hand-operated reciprocating piston pump without compressed air connectionUnlike the compressed-air-operated sampling system for solvents, this drum pump does not require a compressor or gas cylinder. A single pump stroke of the handle is sufficient to deliver the medium through the 32-millimetre-thick immersion tube, at a rate of between 180 and 400 millilitres per stroke, depending on the size. This means the pump can also be used where there is no compressed air supply.Fixed spout for the workplaceThe 170-millimetre-long outlet elbow is rigidly mounted and is suitable for applications where the receiving vessel is positioned directly beneath the outlet. All valves in the pump body are made from solid PTFE or PVDF. For those who wish to fill a vessel located further away using a flexible connection, the structurally identical drum pump with hose and shut-off valve offers a suitable alternative; here, an additional tap at the end of the hose also ensures drip-free shut-off after filling.Three immersion depths, three flow ratesThe shortest version, with a 40-centimetre immersion depth, is designed for canisters of up to approximately 30 litres and delivers around 180 millilitres per stroke. The medium size, with a 60-centimetre immersion depth, is suitable for containers of up to 60 litres, delivering approximately 270 millilitres per stroke. The longest version, with a 95-centimetre immersion depth, is suitable for standard 220-litre drums and delivers around 400 millilitres per stroke; the immersion tube can be infinitely adjusted to the drum depth on all three sizes.Equally suitable for analytical work and chemical handlingIn analytical applications, the most important consideration is that no metal or plastic abrasion enters the sample. In chemical dispensing, on the other hand, resistance to aggressive media over many filling cycles is key. The Ultrarein PTFE drum pump meets both requirements with the same PTFE/FEP pump body, eliminating the need to source different materials for different applications. Simply changing the size is sufficient to scale up from small laboratory containers to standard drums.Cleaning and ReuseThe PTFE pump body can be flushed relatively easily between two different media, as the material itself absorbs hardly any residues. This is an advantage over pumps made of polypropylene or PVC, where some media remain on the surface and may continue to have an effect during the next use. Nevertheless, when switching between significantly different chemicals, it is advisable to use a separate pump for each type of medium to ensure that carry-over is completely ruled out.Typical applicationsFilling with acids and alkalis that would corrode polypropylene or PVCDecanting of high-purity liquids in analytical work and sample preparationUse at workstations without a compressed air supplyDecanting from small to large containers, depending on the selected immersion depthTechnical detailsImmersion tube diameter32 mmOuter outlet diameter12 mmLength of outlet bend170 mmSpout typeOutlet elbowViscosity up to approx.500 mPa·sColourwhiteDrive typemanually operatedPump typeReciprocating piston pumpAdjust immersion depthcontinuously adjustableMaterialPolytetrafluoroethylene (PTFE), Fluoroethylene-propylene (FEP)Overview of variantsItem numberMax. immersion depthFlow rate approx.For tanks up to5606-040040 cm180 ml/strokeapprox. 30 l5606-060060 cm270 ml/strokeapprox. 60 l5606-100095 cm400 ml per strokeapprox. 220 lContentsUltrapure PTFE drum pump with outlet elbow at the selected immersion depthService and procurementFor corrosive media in larger quantities and with an electric drive, the drum pump for acids and alkalis is suitable for flow rates of up to 85 litres per minute.
