Nevis Desktop C

Mini Nitrogen Generator for Laboratory Applications.

Utilising Pressure Swing Adsorption technology the Apex Nevis Desktop provides ideal performance, efficiency and reliability in the smallest foot print in the market! High purity nitrogen is delivered as and when required. The Nevis Desktop can be supplied with an integral compressor for true stand-alone operation.


The small size of the generator allows it to be easily accommodated on top of a workbench. The Nevis Desktop provides flexibility to match your system requirements. We can customise the purity, flow rate and delivery pressure to suit your specifications.

The Nevis Desktop Laboratory Generator produces flows of up to 200cc/min of high purity nitrogen, whilst having the smallest footprint of any nitrogen generator on the market. 


Easily install it on a workbench or in a small space. You receive an uninterrupted supply of high-purity nitrogen whenever you need it, and you never have to pay for bottled gas again.

Flow Rates
Whilst the Nevis Desktop is designed to provide high purity Nitrogen at its optimal flow rate it can be set up to provide higher flow rates at greatly reduced purity levels as indicated here:

Nevis Desktop is the smallest footprint of any nitrogen generator on the market, able to deliver the benefits of an on-site gas generator in a compact package. APEX nitrogen generator range uses a Pressure Swing Adsorption (PSA) technology for superior performance and reliability. Many gas generators use membrane filters which demand a constant replacement and decrease life expectancy. Our nitrogen generators use Carbon Molecular Sieve (CMS) technology consistently outlasting membrane filters and minimising maintenance.


By converting air into high-purity nitrogen, the Nevis desktop generator provides a constant supply of nitrogen suitable for laboratory use. The generator is only 48 centimetres high and 18 centimetres wide. Boost productivity in your laboratory by installing the generator on a workbench or desktop in the best position for your employees.

An on-site nitrogen generator provides several benefits over bottled gas:

  • Save money: You never have to pay for bottled nitrogen again.

  • Save space: A nitrogen generator requires less space than storing gas cylinders.

  • Improve workplace safety: Employees don’t have to move heavy gas cylinders, nor do you have to store high-pressure tanks.

  • Reduce delays: You don’t have to wait for deliveries of bottled gas.


  • Lensing Medium

  • Gas Chromatography

  • IVF

  • Fast Gas Chromatography

  • Flame Ionisation Detection (FID)

  • Ionisation (API-ms)

  • Photonics

  • Any other application requiring low flow rates of high purity nitrogen



All Apex units are supplied with our standard 1 year warranty. Accompanied with our on-going care and servicing facilities Apex provides the highest quality peace of mind.

How it works:


Air either from an external source or from the integral compressor enters the generator via a 0.01-micron filter [1] that removes contaminants and bulk moisture via an integrated auto drain. When the control system assesses that more nitrogen is required, solenoid valve [2] is opened and the pressure is allowed to build in the column [4] containing Carbon Molecular Sieve (CMS) and a residue moisture catcher [3]. This sieve adsorbs the oxygen and leaves the dry nitrogen free to flow into the reservoir [7]. After this point, the Nitrogen is allowed to flow to the application via another 0.01-micron filter [8] and pressure and flow regulators [9].
