Low temperature trap
Freeze trap

VA-250F
Product Code:0029108-000

Fundamental device for centrifugal condensation in terms of efficiency and safety. Three models with different capacity and cooling temperature.



Main Application

As trap of centrifugal condenser (VC-36R/ 96R/ 96W)
As backup cryo-chamber or simple lyophilizer [specialized type]
As water bath for low temperature circulation [specialized type]

Features

Direct cooling system where cooling capacity become trap temperature


Inside chamber with visible cooling coil
This machine has cooling coil inside cooling chamber and can trap vapor more surely than indirect cooling system where cooling coil is outside chamber (means inside device) especially when trapping directly to cooling chamber because cooling capacity become trap temperature without loss.


Direct trap of water and alcohol, use glass condenser for other solvents

Put lid with nozzle (option) on cooling chamber for trapping vapor direct into chamber. Merit of direct trap is temperature of cooling is become trap temperature and can get large volume though it I s limited for water and alcohol since solvent directly touch the device. For trapping other solvents, put glass condenser (option) into chamber.


A: vacuum pump
B: Cooling chamber (use as gas phase)
Use under decompress with lid with nozzle.
C: Trap efficiency is high because vapor hit most effective cooling part of cooling coil. It is especially effective for alcohol and use of high vacuum pump.
D: vacuum pump
It is allowed to connect centrifugal condenser in case tube can be clog by clotting from water.
E: Cooling chamber (use as liquid phase)
Fill with e.g. methanol (beware of fire) and we recommend safer HFE.
F: Vapor is aggregate on cool glass condenser wall and is trapped. It is used for organic solvent and acidic or alkaline solvent which may corrode device materials. Please examine vacuum considering trap temperature as cooling temperature +10ºC.
