Product descriptions and specifications from vendor:
SpeedVac
SC210A Concentrator
PTFE coated chamber provides long lasting durability against harsh solvents
Automatic bleeder valve automatically provides vacuum at the beginning of a run and bleeds chamber to atmospheric pressure at the end of a run
Radiant cover maximizes evaporation/sublimation rates (optional)
VAT4104
Refrigerated Vapor Traps
RVT-series Refrigerated Vapor Traps are reliable, easy-to-use, compact benchtop
traps for solvent vapor condensation and collection. Mechanically
refrigerated vapor traps replace dry ice/methanol traps, and are the easiest, most
practical, and safest way to protect high-vacuum, rotary vane oil pumps in a
vacuum system.
Solvents are removed from samples during vacuum evaporation with a SpeedVac®
Concentrator or during rotary evaporation and are collected in the CFC-free
Refrigerated Vapor Trap. Solvent vapors pass into a Glass Insert Trap or Glass
Condensation Flask and condense on its walls. This prevents the vapors from
reaching and potentially damaging the oil-sealed vacuum pump. When used in
conjunction with the Thermo VaporNet® controller, RVT-series traps provide levels
of solvent recovery equal to the most elaborate liquid nitrogen traps.
The three models differ in trap chamber capacity and in approximate operating
temperature as follows:
Approximate
Trap Chamber Capacity Operating Temperature
RVT100 1 Liter -50 °C
RVT400 4 Liter -50 °C
RVT4104 4 Liter -104 °C
All three are controlled simply by an on/off (I/O) switch. The RVT4104 additionally
displays the trap temperature, and can control power to a vacuum pump through
an auxiliary power outlet. Using this outlet provides an extra measure of
protection for your pump. The RVT4104 employs a cascade (dual compressor)
refrigeration system to achieve its low operating temperatures. The RVT100 and
RVT400 have a single-stage refrigeration system.
Welch 8925 A Pump
The Welch 8925 DirecTorr Direct Drive High Vacuum is a durable vacuum pump with a superior vapor handling capability.
