Nevis Desktop High Flow

Small Nitrogen Generator for High Flow and Lower Purity Applications.

The Nevis Desktop High Flow Laboratory Generator is from the Apex Microgen2 series and is one of the smallest footprint Nitrogen generators available in the world.


This model produces flows of up to 1 L/min of lower purity nitrogen (Apex class 95% as low purity), 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 nitrogen whenever you need it, and you never have to pay for bottled gas again.

The generator is only 48 centimeters high and 18 centimeters wide for a better comparison the above video uses a regular size can (330ml) to indicate the size.


Boost productivity and safety in your laboratory by installing the generator on a workbench, desktop, or in a cupboard in the best position for your employees.

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

  • Fast Gas Chromatography

  • Flame Ionisation Detection (FID)

  • Ionisation (API-ms)

  • Photonics

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