IKA VACSTAR control diaphragm vacuum pump with controller, 0020109375
High-performance 1:1 solution for the laboratory bench The IKA VACSTAR control is a dry 4-chamber diaphragm vacuum pump, specially developed for space-saving and efficient laboratory set-ups. With a pumping speed of 22 l/min and a final vacuum of 2 mbar, it offers sufficient power for typical applications such as rotary evaporators, drying ovens or vacuum filtration. The key advantage: you do not need a separate vacuum controller. The control unit is integrated directly into the pump and regulates the speed as required. This saves space on the bench and drastically reduces the amount of cabling required. Intuitive control and process reliability The detachable display (WiCo) allows for convenient remote operation, for example when the pump is positioned under a fume cupboard. Use the intuitive menu to select the appropriate operating mode: from the fully automatic boiling-point detection mode, which controls processes safely and unattended, through to manual operation and special pumping or cleaning functions. This guarantees maximum reproducibility and protects your valuable samples from delayed boiling or loss. Durability and environmental protection The PTFE diaphragms and chemical-resistant materials make the VACSTAR control extremely robust against aggressive solvent vapours. To protect the environment and the indoor air in the laboratory, the VSE 1 safety emission condenser can be retrofitted as an option. The pump also operates very quietly and with minimal vibration, which noticeably improves working conditions in the laboratory.

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.) Operating pressure: 2.5 bar Pump head material: PPS (polyphenylene sulphide) Diaphragm material: PTFE-coated Valve material: FKM Hose connection: For hoses with an ID of 6 mm Permissible fluid and ambient temperature: +5 °C to +40 °C Voltage: 100–240 V, 50/60 Hz (wide-range power supply) Protection rating: IP 40 Dimensions (W x H x D): 75 x 119 x 156 mm Weight: 1.3 kg Special features: Speed-controllable, status LED, chemical-resistant Contents 1 x KNF LABOPORT ® N 96 diaphragm vacuum pump 1 x mains adaptor (multi-plug) Operating instructions Custom requirements & accessories Do you need suitable vacuum hoses, fine-adjustment valves or suction bottles for your filtration setup?

IKA VACSTAR lite Starter Solution, diaphragm vacuum pump, including emission condenser, 2 mbar, 0010014496
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.
