Description
This listing is for a Ai refurbished T80 -60°C cold trap with two 300mL glass traps and 3 month warranty.
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 prevent vapors being evacuated from an experiment from
entering a vacuum pump where they would condense and contaminate it.
Particularly large cold traps are necessary when removing large amounts
of liquid as in freeze drying.
Pumps
that use oil either 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 condense liquid oxygen (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.
Ai T80 -60°C cold trap features
- No dry ice or liquid nitrogen needed
- All steel housing for durability
- Small footprint
- Plug and play, no assembly required
