Water Jackets

A water jackets can be used to control the temperature of a low pressure column. After a column is suspended inside a water jacket, heated or cooled water can be circulated around the column to control it's temperature. This is most useful when your separation is temperature dependent or when you are processing a thermally unstable material.

Water Jackets are available for all standard Spectra/Chrom® columns longer than 10 cm whose diameter is 5 cm or less. These water jackets slide over the column and permit control of the column temperature with the use of a recirculating water bath.

In order to prevent the column from slipping through the water jacket, we recommend the use of a water jacket support ring. This ring clamps to the upper end plate and prevents it from slipping though the water jacket. Because of the size of the endplates no ring is required on 0.6 cm and 0.9 cm diameter columns. Part numbers for these rings are 124326 (1.5 cm), 124328 (2.5 cm) and 124330 (5.0 cm).

These water jackets of made of borosilicate glass. The hose barbs accept 1/4" to 5/16" ID flexible tubing, preferably silicone or vinyl. Suitable tubing is available from Spectrum as part number 123790 (silicone) or 123786 (vinyl).

In normal use the water is circulated from the bottom of the column toward the top. The top exit port should not be restricted and should flow freely toward a drain or the recirculator tank. Take care that an air bubble does not restrict the water flow at the exit of the hose barb. These water jackets are not designed to be pressurized. They can be used from 0 to 80°C.
