Description

Sample Concentrator Water Bath Nitrogen Blowing Ambient 5~99 Centigrade WD-12
WD-12 Sample Concentration 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
℃
