WD-12 Water Bath Nitrogen Concentrator
Description of the nitrogen concentrator
The instrument consists of a base and stand assembly, sample holder and gas distribution system. Test tubes are held in place by a spring-loaded sample holder and support tray. Each position is numbered. The gas passes through an adjustable flow meter to the distribution manifold. Flexible tubing leads to valve-tube assemblies at each position. Depending on the test-tube size and solvent volume they can be individually raised or lowered to the correct height. Needles blow gas onto the surface of the solution resulting in rapid evaporation of the solvent. All materials used are laboratory quality and can withstand contact with organic solvents. The round, stainless steel water bath is thermostatically controlled and will accurately maintain water temperature from ambient temperature to 99°C.
Features of the nitrogen concentrator 1. LED display, 12 positions2. Copact size takes minimal hood space3. Water bath provides gentl heat4. Circular stand turns so each sample is accessible from the front5. Accommodates samples in test tubes 10 to 29mm diameter, Volumes from 1 ml to 50 ml5.
