Needle Seal Purging Needle

A variety of lengths of the stainless steel sparging needles are available for the S.I.S. Purge & Trap system. All needles are constructed from stainless steel capillary tubing, 0.50 mm O.D. Approximately 10 mm from the flat end a metal hub is attached for the seating and sealing of the needle in the fitting on the S.I.S. liquid purge head. The 5.0 ml sample tubes use the 16.0 cm long needles, and the 25.0 ml sample tubes use the 22.5 cm long needles. In addition the 11.5 cm long needles can be used with standard 12 mm x 75 mm long disposable Pyrex glass test tubes. Additional sizes listed are for use with other sample vials, flasks or specific requirements. Other sizes are available on special request.

Stainless Steel Metal Frit Spargers for the Purge & Trap System

For the most efficient sparging of liquid samples

Sparge Tip Sparge Needle

The stainless steel metal frit spargers have been designed for use with the S.I.S. purge and trap system. They consist of a 1/16" O.D. stainless steel capillary tube attached to a 5.0 micron porous stainless steel frit. This provides for a tiny bubble sparger to efficiently sparge the volatiles from liquid samples. Two sparger lengths are available. The 16 cm length is for use with the S.I.S. 5.0 ml sample tubes and the 22.5 cm length is for use with the S.I.S. 25.0 ml sample tubes.

The capillary tube is held in place in the adaptor fitting with standard 1/16" graphite or graphitized / vespel ferrules.
