WTW SenTix 41 analogue pH electrode, integrated temperature sensor, 103635
The WTW SenTix 41 analogue pH electrode is a tried-and-tested electrochemical system solution for reliable, low-maintenance pH measurement in routine laboratory applications, educational institutions and field measurements. Designed for use with classic analogue pH meters from the WTW inoLab and Profiline series, this high-quality electrode offers precise signal transmission and extremely simple handling. For daily monitoring measurements in aqueous media, wastewater samples or environmental investigations, the focus is on straightforward, rapid deployment – which this robust combination probe guarantees whilst being gentle on materials and ensuring process reliability. Traditional analogue technology and integrated temperature compensation The mechatronic system architecture of the SenTix 41 is based on reliable, analogue signal transmission. The measured potential is transmitted via a shielded fixed cable directly to the analogue input stage of the pH meter. A key functional feature is the NTC 30 kOhm temperature sensor integrated into the sensor head. This sensor measures the sample temperature simultaneously with the pH value, enabling the connected meter to perform automatic temperature compensation in real time. This reliably eliminates thermodynamically induced measurement errors caused by fluctuating ambient temperatures, without the need to immerse a separate temperature sensor in the sample. Low-maintenance gel electrolyte and mechanical breakage protection The material design is consistently optimised for durability and minimal maintenance in everyday laboratory use. The electrode is fitted with a chemically resistant and extremely break-resistant POM plastic shaft. This shaft encloses the sensitive glass membrane like a mechanical protective cage and prevents damage in the event of falls or contact with vessel walls. A maintenance-free gel electrolyte, combined with a tried-and-tested fibre diaphragm, serves as the reference system. This sealed system permanently eliminates the need for the tedious refilling of liquid KCl solution and significantly reduces the risk of diaphragm blockages in multi-user operations. Universal connectivity and ergonomic laboratory use To ensure seamless integration into equipment, the SenTix 41 features a permanently attached 1-metre cable terminated in tried-and-tested standard connectors. The pH channel is connected via a standard DIN plug, whilst the integrated temperature sensor is connected via a 4 mm banana plug.

IKA C-MAG HS 7 magnetic stirrer package with heating, glass-ceramic base plate, including ETS-D5, 0010016454
The IKA C-MAG HS 7 Package magnetic stirrer with integrated heating represents a highly advanced, thermomechanical system solution for the precise mixing, heating and controlled temperature regulation of liquids in chemical, pharmaceutical and university laboratories. Designed as a high-performance complete system, this setup is validated for continuous stirring tasks up to a volume of 10 litres (based on water). For demanding thermal syntheses, the digestion of aggressive media or sample preparation, the precise interplay between high thermal energy input and a completely chemical-resistant work surface is the primary criterion for guaranteeing reliable experimental procedures that are gentle on the material and ensure process reliability. Highly chemically resistant glass-ceramic heating plate and powerful drive The process engineering foundation of the unit is the square heating plate (180 x 180 mm) made from seamless, high-quality glass-ceramic. This choice of material ensures unrivalled chemical resilience against extremely aggressive acids, alkalis and high-purity solvents. Furthermore, the non-porous glass surface enables gentle, residue-free cleaning. With a powerful heating output of 1,000 watts, the system achieves extremely short heat-up times to a plate temperature of 500 degrees Celsius. The integrated motor covers a wide speed range from 100 to 1,500 revolutions per minute and, thanks to strong magnetic coupling, reliably keeps the magnetic stir bar on track even with more viscous solutions. Precise temperature control via the integrated ETS-D5 contact thermometer The standout feature of the “Package” version is the IKA ETS-D5 electronic contact thermometer included as standard. The precision sensor is connected directly to the magnetic stirrer’s electronics via the integrated DIN 12878 socket. The sensor is immersed gently into the sample medium and reports the actual temperature in real time. This mechatronic control loop enables highly precise temperature control directly within the liquid, with outstanding control accuracy of ±0.5 K. Thermodynamic overshoots and unwanted overheating of sensitive samples are thus effectively eliminated during day-to-day field use. Ergonomic housing design and uncompromising health and safety The structural safety of the C-MAG HS 7 complies with strict GLP guidelines for long-term laboratory operation. The user interface features a raised control panel, which reliably protects the underlying electronics and displays from dripping or spilled liquids. An easy-to-read digital LED display accurately shows the set target temperature, whilst a digital error code mode immediately visualises any malfunctions. The integrated ‘Hot Top’ warning indicator ensures maximum occupational safety: a visual signal flashes for as long as the plate surface is heated to over 50 degrees Celsius – even after the unit has been switched off completely. A fixed safety cut-off at 550 degrees Celsius also prevents thermal damage to the heating mat.

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.

IKA C-MAG HS 7 control, magnetic stirrer with heating, ceramic hotplate, 0020002694
Thermodynamic infrared transmission and amorphous ceramic matrix The introduction of extremely high thermal energy into chemical reaction systems requires material architectures that are thermophysically resistant to massive temperature gradients. The IKA C-MAG HS 7 control utilises a monolithic base plate made of glass-hard, amorphous industrial ceramic (180 x 180 mm). This microstructured ceramic plate is not only characterised by absolute chemical inertness towards highly corrosive acids, halogens and bases, but also acts as an excellent infrared transmitter. With a massive heating capacity of 1,000 watts, the system generates surface temperatures of up to 500 °C. The thermal energy is not primarily transferred via pure heat conduction, but is coupled deep into the glass matrix of the reaction vessel with a high proportion of infrared radiation. This minimises thermodynamic latency and enables extremely rapid heating rates for high-boiling-point solvents or melt digestion. Electromagnetic kinematics and rheological trend metrology The physical mixing of structurally viscous fluids up to a macroscopic volume of 20 litres requires a constant, slip-free torque. The system generates a strong alternating electromagnetic field that continuously synchronises the stirring rod within the medium at speeds of 50 to 1,500 revolutions per minute. The electronic motor control compensates for rheological resistance in real time. A fundamental analytical function of this cybernetic model is the measurement of the relative torque trend. The system measures the electromagnetic phase shift induced by changes in the fluid’s viscosity during molecular polymerisation, cross-linking or crystallisation processes, and displays this vector change directly on the high-resolution LCD display. System cybernetics and hardened interface architecture To protect the electronic control unit in toxic or highly corrosive laboratory environments, the entire user interface is isolated behind a monolithic, chemically resistant sheet of real glass (hardened glass). Thermodynamic control within the medium is achieved via a PID cascade control system directly coupled to the supplied PT 1000 temperature sensor, thereby physically eliminating thermal overshoot. An independent, hardware-based safety circuit (continuously adjustable from 100 to 650 °C) and the IKA SmartTemp ® optical warning system guarantee absolute occupational health and safety by warning of latent infrared residual heat from the ceramic matrix, even after the primary power supply has been disconnected. Technical Details Thermodynamics & Heating Technology Heating power: 1000 W Heating temperature range: room temperature to 500 °C Base material: Amorphous industrial ceramic (monolithic) Base dimensions: 180 x 180 mm Heating rate control: Anticipatory PID control (with external PT 1000) Heating plate setting and display resolution: 5 K Setting and display resolution for the medium (via probe): 1 K Temperature control accuracy (with PT 1000 in the fluid): ± 0.5 K Heating rate (1 litre of H₂O in H 1500): 5 K/min Metrology & Control Engineering Viscosity measurement: Relative torque trend measurement (Torque Trend) Timer function: Integrated, cybernetically controllable Temperature sensor interface: PT 1000 (DIN) for ETS-D5 / ETS-D6 or direct connection Sensor failure detection: Error 5 (Sensor in Medium Detection) Cybernetic interface: High-contrast LCD beneath tempered real glass Kinematics & Mechanics Speed range: 50 – 1,500 rpm Motor power input / output: 9 W (mechanical transmission) Speed deviation (under rated load): ± 2 % Maximum stirring volume (based on H₂O): 20 litres Maximum stir bar length: 80 mm (minimum 30 mm) Reversible direction of rotation: Yes, programmable interval operation Safety & environmental conditions Hardware safety circuit: Adjustable from 100 to 650 °C Residual heat indicator: IKA SmartTemp ® (Hot Top Indicator) Permissible ambient temperature range: 5 – 40 °C Permissible relative humidity: max. 80 % Protection class (according to DIN EN 60529): IP 21 Infrastructure, Electrical & Connectivity System dimensions (W x H x D): 220 x 88 x 354 mm Weight: 4.0 kg Voltage / Frequency: 220 – 230 V / 50/60 Hz Power consumption: 1020 W (standby: 2 W) Data interfaces: USB and RS 232 (for firmware updates and LIMS/labworldsoft ® connection) Scope of delivery 1 x IKA C-MAG HS 7 control magnetic stirrer 1 x PT 1000.80 temperature probe (stainless steel) 1 x IKAFLON ® magnetic stirring bar 1 x USB cable and mains lead (Important note: Support rods and sleeves for vertically securing the PT-1000 probe at the centre of the flow vortex are not included in the scope of delivery!) Customised requirements & accessories The C-MAG HS 7 control is a high-performance thermodynamic instrument that achieves its control precision solely through the exact positioning of the sensor system. To complete the PID control loop, the supplied PT-1000 probe must be positioned freely within the liquid phase. For this purpose, vertical locking using an IKA support rod (H 16 V) and cross-shaped sleeve (H 44) is essential. If the probe comes into contact with the hot vessel wall, this would distort the cybernetic control loop. For highly corrosive media that attack stainless steel, we recommend switching to the glass-sheathed PT 1000.70 probe. Please contact our procurement service at any time for the thermodynamically correct configuration.

IKA T 25 digital LR disperser, for laboratory reactors, 2000 ml, 0020008820
Fluid dynamics precision in closed reactor systems In chemical process engineering, the synthesis of nanoparticles and the production of complex pharmaceutical emulsions, the scale-up from the laboratory to the pilot phase requires absolute control over phase distribution. Conventional, open dispersion processes in beakers inevitably lead to the ingress of atmospheric oxygen (oxidation) due to vortex formation and to the uncontrolled loss of volatile organic compounds (VOCs). The IKA T 25 digital LR disperser (the abbreviation “LR” stands for laboratory reactor) is specifically designed for high-precision high-shear dispersion in hermetically sealed, temperature-controlled and evacuated reactor systems. Powered by a robust 800-watt high-performance motor, this drive unit handles process-relevant volumes ranging from 1 to 2,000 millilitres (based on the physical viscosity of water). The unit thus bridges the critical process engineering gap between initial formulation development on a millilitre scale and simulated industrial production. Thermodynamics and cavitation in the rotor-stator principle The breakdown of stubborn agglomerates and the disruption of viscous liquid droplets (emulsification) requires the massive, localised application of kinetic energy. The T 25 digital LR operates with a continuously and electronically adjustable speed range from 600 up to a staggering 25,000 revolutions per minute. In combination with the specific IKA dispersing tools, immense circumferential speeds of over 22 metres per second are generated at the outer edge of the rotor. The radial acceleration of the media into the extremely narrow shear gap between the rotating element and the stationary stator generates immense hydrodynamic shear forces, high-frequency pressure fluctuations and physical cavitation effects. Particles and droplets are broken down into microscopic primary sizes in the low micrometre range within milliseconds. The thermal energy inevitably generated by molecular friction can be dissipated in a controlled manner in a professional reactor system via external cooling jackets, in order to protect thermolabile analytes from denaturation. Vacuum compatibility and specific reactor geometry The key design difference between the T 25 digital LR and conventional laboratory homogenisers is its physical and geometric system integration. The unit is mechanically engineered to be precisely coupled with IKA’s specialised KD-LR (laboratory reactor) dispersion tools. These specialised tool shafts feature high-quality, high-vacuum-compatible mechanical seals made of FFPM and PTFE. In this configuration, the drive enables high-speed dispersion under a system vacuum of up to 50 mbar. Evacuating the reactor whilst active dispersion is taking place prevents the formation of disruptive aerosols and foam in media containing surfactants, completely rules out the oxidative degradation of active pharmaceutical ingredients (APIs) and guarantees the production of absolutely bubble-free, highly viscous gels or creams. Furthermore, the LR tools are designed with an extended length to penetrate deep into the reaction vessels (such as the LR 1000) and fully capture even minimal dead volumes at the bottom of the reactor. Scalability and rheological behaviour of multiphase systems A fundamental problem in the dispersion of non-Newtonian fluids is the change in rheological properties under sustained shear stress (structural viscosity). Thanks to its precise energy input, the IKA T 25 digital LR enables the exact investigation of these phenomena directly within the reactor. During the production of solid suspensions, the stator breaks down the electrostatic van der Waals forces responsible for agglomeration. In liquid-liquid systems, the turbulent flow prevents the coalescence of droplets until added emulsifiers physically stabilise the interfacial tension. Digital process control and electronic safety mechanisms To ensure complete reproducibility in a regulated environment (GLP/GMP), the T 25 digital LR is equipped with an LED display for continuous monitoring of the actual speed. An integrated microprocessor continuously adjusts the power output. If the viscosity of the medium increases due to polymerisation setting in during the reaction, the electronics maintain the speed absolutely constant despite the growing hydrodynamic resistance. To protect the hardware, the drive features multi-stage overload protection. Should the rotor become suddenly blocked in the shear gap, a physical current limiter intervenes immediately, switching off the motor and issuing an error code. This prevents thermal damage to the motor windings and guarantees the longevity of the laboratory infrastructure. Technical details Product type: High-shear disperser for laboratory reactors Volume range (H₂O): 1 – 2,000 ml Motor power (input/output): 800 W / 500 W Speed range: 600 – 25,000 rpm (electronically continuously variable) Speed display: Digital (LED) Max. permissible viscosity of the medium: 5,000 mPa·s Noise level (without dispersing tool): 75 dB(A) Operating principle: Rotor-stator technology (high shear forces / cavitation) Vacuum compatibility: The system is designed for vacuum operation when used in combination with KD-LR tools Process reliability: Electronic speed control maintains a constant speed despite changes in viscosity Motor protection: Electronic overload protection and current limiting with error code output Permissible duty cycle: 100% (continuous operation) Dimensions (W x H x D): 87 x 271 x 106 mm Arm length / arm diameter: 160 mm / 13 mm Weight: 2.5 kg Protection class (to DIN EN 60529): IP 20 Permissible ambient temperature: 5 – 40 °C Contents 1 x IKA T 25 digital LR drive unit (800 W, for laboratory reactors) 1 x mains lead for IT equipment 1 x Comprehensive operating instructions (Important note: The essential KD-LR series dispersing tool, stands and the laboratory reactor itself are not included in the scope of delivery!) Individual requirements & accessories The T 25 digital LR is a drive motor only. To operate the system in your laboratory reactor (such as the IKA LR 1000), you must have a suitable dispersing tool designed for a physical vacuum seal (for example, the IKA S 25 KD - LR - 25 G). For a safe and vibration-free setup, you will also need a stand solution, unless the unit is mounted directly onto the reactor stand. Please contact our procurement service at any time for a fluid-dynamically precise design of your rotor-stator geometry and its integration into your reactor system.
IKA S 18 N - 19 G Dispersing tool, coarse, PTFE bearings, 10 – 1,500 ml, L004640
Robust and efficient: the coarse dispersion tool for your T 18 The IKA S 18 N - 19 G (MPN L004640) is the standard tool for coarse dispersion tasks with the popular drive units of the IKA T 18 series (e.g. T 18 digital ULTRA-TURRAX ®). This high-quality stainless steel tool covers a wide volume range from 10 ml to 1,500 ml (H₂O), making it the ideal choice for day-to-day sample preparation involving rapid grinding and mixing. Toothed geometry (“G”) for optimal grinding The letter “G” in the model designation stands for “coarse”. Unlike fine-tooth tools, the stator of this model features a coarse-toothed geometry with wider slots. This makes the S 18 N – 19 G the perfect choice for: Pre-grinding: Rapid breaking up of solid sample components in liquids. Coarse suspensions: Mixing in pigments or fillers. Viscous media: Processing of samples that would be too viscous for finer tools or could cause them to become blocked. It operates extremely efficiently and ensures homogeneous distribution in the shortest possible time. Durable PTFE bearing (“N”) The rotor shaft is mounted in a high-quality PTFE (Teflon) bearing. This choice of material (“N”) offers crucial advantages in everyday laboratory use: PTFE is chemically almost inert. This means you can use the tool without hesitation with aggressive solvents, acids and alkalis without the bearing being damaged. Important application note: PTFE bearings rely on the medium for lubrication and cooling. The instrument must therefore not be allowed to run dry, as the frictional heat would otherwise destroy the bearing. Hygiene and material quality Manufactured from electropolished stainless steel (AISI 316L), the tool meets the highest hygiene standards. It is robust, corrosion-resistant and durable. For applications in the medical or microbiological fields, the S 18 N - 19 G can be easily dismantled and fully sterilised – whether by chemical disinfection, hot air or in an autoclave (wet sterilisation). This guarantees germ-free processes and prevents cross-contamination between different sample batches. Technical data Compatible drive: IKA T 18 digital ULTRA-TURRAX ® Working range (H₂O): 10 – 1,500 ml Stator diameter: 19 mm Rotor diameter: 12.7 mm Design: G = Coarse Bearing: N = PTFE bearing Material (in contact with the medium): Stainless steel (AISI 316L), PTFE Max. temperature: 180 °C Generator gap: 0.5 mm Immersion depth: 35 – 170 mm Sterilisation: All methods (fully autoclavable) Contents 1 x IKA dispersing tool S 18 N - 19 G (Drive unit not included) Individual requirements & accessories Do you need a tool for even finer emulsions?

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.

Memmert SN55 Hot-Air Steriliser (53 l, natural convection), up to +250 °C
The Memmert SN55 is a hot-air steriliser classified as a Class IIb medical device, which has been specially developed for the safe sterilisation of medical instruments and containers using dry heat. Unlike models with forced air circulation, the SN55 (S=Steriliser, N=Natural convection) operates using natural convection. The absence of a fan eliminates the risk of fine particles or germs being dispersed throughout the interior by air turbulence – a crucial factor when handling critical loads. Validatable process reliability The most critical parameter in sterilisation is not the duration of the programme, but the dwell time at the setpoint temperature. The SN55 features the essential SetpointWAIT function: the process time only begins to run once the setpoint temperature has actually been reached at all measurement points inside the chamber. This prevents the heating phase from being incorrectly counted as sterilisation time and guarantees the reproducibility of cycles in accordance with medical standards. Hygienic Design & Heating Concept The interior is made of deep-drawn, stainless steel (grade 1.4301) and is particularly easy to clean thanks to its large radii. Memmert employs all-round heating: the heating elements are protected within fins on all four sides of the interior. This ensures excellent temperature uniformity and direct heat transfer to the items being sterilised, even without a fan. The unit is controlled via the intuitive “SingleDISPLAY” (TFT colour graphic display), which precisely regulates parameters such as temperature and flap position. Technical details Internal chamber volume: 53 l Temperature range: +5 °C above room temperature to +250 °C Convection type: Natural convection (no fan) Medical device: Class IIb (in accordance with MDD 93/42/EEC) Internal dimensions (W x H x D): 400 x 400 x 330 mm Housing dimensions (W x H x D): 585 x 784 x 514 mm Max. total load: 80 kg Max. load per shelf: 20 kg Control system: SingleDISPLAY (PID microprocessor) Temperature sensor: 1 Pt100 (DIN Class A) Power consumption: approx. 2000 W (at 230 V) Protection class according to DIN EN 60529: IP 20 Scope of delivery Memmert SN55 hot-air steriliser 1x stainless steel wire rack (electropolished) Factory calibration certificate (at +160 °C) Operating instructions Customised requirements & procurement service Do you require the “TwinDISPLAY” version (SN55plus) for complex ramp programming, or additional wire racks to maximise the loading area? We can also configure your unit with side feed-throughs for external sensors or assist you with qualification (IQ/OQ).

Memmert SF260 Hot-Air Steriliser, 256 L, Class IIb medical device
Reliable sterilisation for hospitals, medical practices and laboratories The Memmert SF260 hot-air steriliser is a Class IIb medical device (in accordance with MDD 93/42/EEC) designed for the sterilisation of medical materials using dry heat at atmospheric pressure. With an internal capacity of 256 litres and a temperature range of +20 °C to +250 °C, the unit is suitable for hospitals, medical practices and laboratories that need to sterilise large quantities of instruments and containers reliably and with full documentation. Precise temperature control with SetpointWAIT A Pt100 sensor using the 4-wire measurement method (DIN Class A) measures the temperature with an accuracy of ±0.1 °C up to 99.9 °C and ±0.5 °C from 100 °C onwards. The SetpointWAIT function only starts the sterilisation time once the setpoint temperature has actually been reached – ensuring validatable, reproducible cycles. An electronically controlled turbine circulates the air in adjustable 10 per cent increments, whilst electronically controlled fresh air and exhaust air dampers ensure controlled air exchange. Robust construction and safety The interior is made of stainless steel with deep-drawn ribbing and is heated on all four sides; the fully insulated stainless steel door locks via a two-point compression lock. For safety, the unit monitors the temperature electronically and additionally via a mechanical temperature limiter (DIN 12880 Class 1), which triggers at around 20 °C above the maximum temperature. An integrated self-diagnostic system automatically detects faults. Operation, interfaces and documentation The SF260 is controlled via the ControlCOCKPIT SingleDISPLAY: an adaptive digital PID microprocessor controller with a high-resolution TFT colour graphic display and a digital timer (1 minute to 99 days). Log data can be read out and archived via the Ethernet interface or using a USB stick with AtmoCOCKPIT software – the programme sequence remains stored even after a power cut. This significantly simplifies documentation for quality management.
