Buchi glassware design
All original Buchi digestion glassparts are made of high temperature and chemical resistant borosili- •
cate glass.
Acid fumes generated during digestion accumulate in the suction module
•
The fumes must be safely withdrawn from the suction module via one or more hoses to a Scrubber •
(e.g. Scrubber B-414) or via water jet pump into a sink or sufficient suction flow.
3rd party glassware
The quality of the material is an essential part of the safety concept of the SpeedDigester K-439. For
the special rack (order no. 11055440), the following qualified vendors offer sample tubes of sufficient
quality grade to withstand the temperatures and the aggressive chemical digestion agents:
