Long Live, High Quality: Perfluorinated PTFE Digestion Vessels

Digestion vessels made of isostatically compressed TFM-PTFE last several years without deteriorating in quality while at the same time the containers are characterised by their low cost compared to those made of other materials. For this reason they are therefore the preferred vessels for use in modern laboratories.
