behr "K" blocks with high-quality non-corrosive block casing made of stainless steel are optimally suited for nitrogen determination if the user is working with standards that allow for traditional block digestion systems, yet not infrared rapid digestion units.

Caution: For other acid digestions, such as for phosphate determination, it is absolutely necessary that the gases are first neutralized in a behrotest® extraction system (behrosog 3 or SIMVAC) before they enter the hood. The behrotest® micro digestion blocks make only use of 100 ml vessels, the macro series 500 ml vessels. 250 ml vessels are used for behrotest® standard digestion blocks.
