Description
SR5 behrotest round-bottom digestion vessel is a 400 ml glassware component designed for use with K-blocks in Kjeldahl and related digestion workflows. The round-bottom geometry promotes uniform heat transfer during acid digestion and sample mineralisation, supporting reproducible preparation of analytical samples. With a working volume of 400 ml, the vessel suits typical laboratory digestion loads while remaining compatible with block systems specified for K-block formats. Supplied as a single piece, it integrates into existing digestion equipment setups used for nitrogen determination and comparable wet-chemical procedures. This digestion vessel from manufacturer Behr is intended for laboratories that standardise on behrotest K-block accessories and require matching round-bottom glassware. Categories linked to Kjeldahl digestion apparatus underline its role in sample preparation rather than general storage. Clear identification as the SR5 type helps maintain consistent glassware inventories across multi-position digestion blocks, ensuring correct fit and reliable thermal contact during heating cycles in routine analytical practice.

Questions about SR5 behrotest round bottom vessel 400 ml for K- blocks
What is this article?
SR5 behrotest round bottom vessel 400 ml for K- blocks is the article on this page. Luminix Health distributes Behr for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Matériel de laboratoire.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
