KNF LABOPORT N 96, very compact, chemical-resistant diaphragm vacuum pump with manual speed control, 322806

For those who have limited space on their lab bench but still need a reliable, chemical-resistant vacuum source, the KNF LABOPORT N 96 is a highly compact, oil-free diaphragm vacuum pump. Weighing just 1.3 kg and measuring 75 x 119 x 156 mm, it fits next to almost any workstation and can be precisely adjusted to the specific application via the manual speed control, for example for filtration, liquid aspiration or solid-phase extraction (SPE).

Very compact and lightweight

Measuring just 75 x 119 x 156 mm (W x H x D) and weighing 1.3 kg, the N 96 is the most compact pump in our LABOPORT range. Its small footprint makes it a practical addition to workstations where there is no room for larger vacuum pumps, such as directly next to a filtration unit or an SPE setup.

Chemical-resistant materials, tailored to the design

The pump head is made of PPS (polyphenylene sulphide), the diaphragm is PTFE-coated, and the valves are made of FKM. This combination of materials differs from that of the larger LABOPORT-N pumps (which feature a TFM PTFE pump head and FFPM valves), but is designed specifically for the compact design of the N 96 and its intended applications.

Manual, stepless speed control

The N 96’s flow rate can be continuously adjusted to suit the specific application via the manual speed control. According to the manufacturer, this ensures exceptional ease of use in day-to-day laboratory work and enables precise vacuum control, for example when gently filtering sensitive samples.

Up to 2.5 bar operating pressure, not just vacuum

In addition to a maximum ultimate vacuum of 130 mbar (abs.), the N 96 also achieves an operating pressure of up to 2.5 bar (rel.). This means it can be used not only for evacuation but also, where required, for pumping under slight overpressure, a difference from the larger LABOPORT-N pumps, which are primarily designed for vacuum operation.

Mains-powered via an external plug-in power supply

The pump itself operates at 24 V DC and is powered via an external plug-in power supply with a wide-range input (100 to 240 V AC, 50/60 Hz); it does not have a built-in battery. The power consumption is 19 W; the pump’s operating current is 0.9 A, whilst that of the power supply unit is 0.4 A (230 V AC) or 0.7 A (100 V AC). The protection class is IP40. Permissible media and ambient temperatures range from +5 to +40 °C.

Maintenance-free and 100 % oil-free

According to the manufacturer, the N 96 operates maintenance-free and is 100 % oil-free. There is no need for regular oil changes, and there is no risk of oil mist entering the gases being pumped or the laboratory air, an advantage wherever contamination-free conditions are required, such as during sample preparation for analysis.

Gas connection and accessories

The gas connection is a 1/8 NPT fitting; the supplied hose connector has an internal diameter of 6 mm and is made of PP. A column mounting bracket is available for wall mounting if required, along with a spare parts kit and a power supply set for replacement purposes.

Suitable for confined spaces

As the N 96 is powered by an external plug-in power supply, the pump housing itself remains particularly compact, an advantage wherever shelves, fume hoods or workstations are already densely occupied. The column mount also allows for space-saving installation away from the worktop, for example on a stand or a wall within easy reach of the workstation.

Typical applications

• Filtration
• Liquid aspiration
• Solid-phase extraction (SPE)

For example, the N 96 can be placed right next to an SPE cartridge stand, where it provides the necessary vacuum for sample purification in a space-saving manner, without the need for a separate, bulky pump setup.

Need a higher flow rate? The larger LABOPORT series

If the flow rate of 7 l/min is insufficient for a larger application, or if there is an additional need to collect liquids and condensate or to recover solvents, we offer the larger LABOPORT series: the pure diaphragm vacuum pump N 820 G / N 840 G (20 and 34 l/min respectively), the SR 820 G / SR 840 G vacuum pump system with two separator bottles, and the SH 820 G / SH 840 G vacuum pump system with a separator and high-performance condenser for solvent recovery.
