Automatic sample preparation system VacPrep

for the laboratory

The VacPrep features six degassing stations, and a choice of vacuum or gas flow preparation on each of the six stations. The VacPrep™ 061 offers two methods for removing contaminants. In addition to flowing gas, it provides vacuum to prepare samples by heating and evacuation. This combination allows you to choose the preparation method that is best suited to your material or application. The VacPrep features six degassing stations, and a choice of vacuum or gas flow preparation on each of the six stations. Needle valves are also provided allowing you to introduce the flowing gas or vacuum slowly to prevent fluidization of samples. Specifications Sample Tubes: Up to 3.0-cm (1 3/16-in.) OD bulbs with 1/4-, 3/8-, or 1/2-in., 9mm, 12mm OD stems. Heating Block: Temperature: 10 ºC above ambient to 400 ºC Temperature Accuracy: ±10 ºC Electrical Voltage: 100, 120, 220, 240 VAC r10% Power: 250 VA maximum Frequency: 50/60 Hz Environment Temperature: 10 to 35 ºC operating; 0 to 50 ºC non-operating Humidity: Up to 90% relative, non-condensing Gases Used: Helium, nitrogen, argon, or any other pure gas that does not adsorb at room temperature. Flow Rate (flowing gas preparation): Up to 50 cm3/min. Vacuum System A vacuum source achieving better than 20 µmHg at the instrument inlet, and having a device to reduce oil vapor backstreaming is recommended. The vacuum system must also have an anti-suckback valve to prevent oil from flowing into the VacPrep should there be a power failure.
