PYREX®, borosilicate glass arsenic determination apparatus designed for the estimation of arsenic and antimony.

Supplier: BUCHI

The KjelDigester provides fast and safe digestion of up to 20 samples simultaneously.

Supplier: BEHR

In the behrotest® nitrogen station, solvent is evaporated under ambient temperature conditions by using a mild nitrogen flow. A distributor leads the nitrogen flow through two individually adjustable tubes into the Kuderna-Danish flasks. Thus the two samples reduce simulataneously.

Supplier: BUCHI

Digestion of protein samples with sulphuric acid and catalyst requires prolonged periods of heating and is traditionally carried out in block heaters. The SpeedDigester design features IR heating that provides fast preheating and cool down. The models described below provide a range of flexible options with different levels of sophistication and control.
