White Dwarf - High Performance Annular Cold Trap (Glycol Version)

Using our Teflon coated alloy & finned condenser technology, we have increased cold trapping potential & performance.

• Our alloy is 16 times more thermally conductive than stainless steel, and 200 times more conductive than glass--this allows the condensing surface to maintain colder and more consistent temperatures.
• Finned design increases the total surface area, when compared to typical annular style cold traps.
• Specialized hydrophobic PTFE sintering process sheds condensate easily and provides an increased number of nucleation sites--which assist in converting vapors to liquids.
• Our food-grade chemically-inert surfaces, ensure your condensate remains preserved, pure, and unadulterated.

Design

Since the trap is internally baffled, having the inlet & outlet in-line is, in this case, an advantage.

In the White Dwarf, the vapor flow travels into the shell making immediate contact with the cold condenser surface head on, then down and through half of the condenser fins, through the suspended condensate container, then back upwards across the other half of the condenser fins, before finally exiting through the exhaust port.

This method results in maximum condenser contact and increased residence times in the trap (about double that of offset ports), all while still maintaining low impedance!  

DID YOU KNOW?

In other cold trap designs, the condensate pools at the base of the outer shell where it absorbs heat, which often causes the condensate to re-vaporize and pass through & back out of the trap (loss), or be re-condensed back to a liquid (reflux). These factors occupy cold trap resources, and are detrimental to cold trap performance.

By suspending the majority of the condensate above the shell base, the White Dwarf minimizes heat transfer between the condensate and the shell.
