Accessories

Glassware and Accessories 

Each SmartDigest 40/20 is supplied with a complete set (customer's choice) of one (1) of the following thick-walled digestion tubes that are calibrated for

75 ml. SmartDigest 40 (40 tubes)
100 ml. SmartDigest 40 (40 tubes)
250 ml. SmartDigest 20 (20 tubes)

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 fluctuations 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.
