-40℃ Cold Trap CT-40PDF DownloadShare With:
Cold Trap is used to capture water vapor and harmful gases emission from vacuum drying oven and pressure reduced concentration device, improving efficiency of vacuum system, extending life-span of vacuum pump.
The newly re-designed -40℃ Cold Trap CT-40 has a much smaller footprint, but at the same time, offering you the same cooling power, 1.5X reservoir and 1.6X trap capacity. New updated hose barb ports provide you safer and easier vacuum tubing connection and removal.
●1.5X more reservoir and 1.6X more trap capacity compare to its predecessor.
●No dry ice or liquid nitrogen needed.
● All steel housing for durability.
●Small footprint, built-in swivel casters for mobility.
●Plug and play, no assembly required.
●It can be used in drying system for capacitor, battery pole and battery cell.
●It also can be used as pre-freezing bath and low temperature bath.
●Digital display for better control of the bath temperature, which makes it easier to start the vacuum pump at right time.
●Stainless steel 304 liquid bath can be used to do water or ethanol cooling experiments. If equipped with glass condenser, it also can be used to deal with acid or organic solvents.
●Designed with drain valve for easy discharge of collected liquid.
In vacuum applications, a cold trap is a device that condenses all vapors except the permanent gases into a liquid or solid. The most common objective is to prrevent vapors being evacuated from an experiment from entering a vacuum pump where they would condense and contaminate it. Paticularly large cold traps are necessary when removing large amounts of liquid as in freeze drying.
Pumps that use oil eigher as their working fluid (diffusion pumps), or as their lubricant (mechanical rotary pumps), are often the sources of contamination in vacuum systems. Placing a cold trap at the mouth of such a pump greatly lowers the risk that oil vapors will back stream into the cavity.
Care should be taken when using a cold trap not to cendense liquid oygen (a light blue liquid) into the cold trap. Liquid oxygen is potentially explosive, and this is especially true if the trap has been used to trap solvent. Liquid oxygen can be condensed into a cold trap if a pump has sucked air through the trap when the trap is very cold.
