The VacPrep features six degassing stations, and a choice of vacuum or gas flow preparation on each of the six stations.
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.
Temperature: 10 ºC above ambient to 400 ºC
Temperature Accuracy: ±10 ºC
Voltage: 100, 120, 220, 240 VAC r10%
Power: 250 VA maximum
Frequency: 50/60 Hz
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.
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.
