Sample concentrator

Description

Sample concentrator - SD**2 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 dry bath is thermostatically controlled and will accurately maintain water temperature from ambient temperature to **0℃. The heating medium is Alumina ball. Features 1. LED display, *2 positions 2. Copact size takes minimal hood space 3. Dry bath (heating medium: Alumina ball ) provides gentl heat 4. Circular stand turns so each sample is accessible from the front 5. Accommodates samples in test tubes *0 to *9mm diameter, Volumes from 1 ml to *0 ml 5. A gas flow meter with valve, controls and indicates gas consumption 6. A needle valve adjusts gas flow at each position 7. Stainless steel **0mm- gauge needles standard 8. All metal parts are made of stainless steel, nickel chromed brass or anodized aluminum 9. Plastic parts are laboratory grade and will withstand contact with common organic solvents ***** setting range: Ambient temperature ~ **0 ℃ ***** control accuracy: ±1℃
