Water Jackets

Some chromatographic interactions can be affected by temperature. A water jacket allows you to control the column temperature using a recirculating water bath. The water jacket can be used to raise or lower the temperature to match your application, but the temperature should be kept between 0 and 80°C. For best you should also control the temperature of the fluid being pumped into the column.

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.
