Glassware and Accessories

Distillation glassware is available for the following analytes:

• ammonia
• cyanide
• fluoride
• phenol
• sulfide, total
• sulfide, acid-soluble

The cyanide, fluoride, and both sulfide, a 10-position gas/vaccum distribution manifold is required. In addition, all the flexible tubing is provided as well as a comprenhensive methods manual.

Digestion
A set of 20 digestion tubes calibrated to 250 ml.

Stand
The stand holds the tubes during the digestion process, dilution, washing, and transfer. Specifically designed side plates snap onto the stand to minimize temperature fluctuatins from air drafts during digestion.

Retainer Plate
The retainer plate locks the tubes in position in the rack allowing the entire assembly to be turned upside down to facilitate cleaning.
