BD50 & BD28 Digestion Block


Digestion Block for Kjeldahl Digestion
BD50 & BD28 Digestion Block
Digestion Block SystemThe SEAL Analytical Digestion Block is your key to successful kjeldahl digestions. The BD50 Digestion Block automates acid digestions for up to 50 laboratory samples simultaneously. It is ideal for Total Nitrogen (TKN) and Phosphorous (TP) digestion. The SEAL Analytical Digestion Block uses a microprocessor to precisely control digestion conditions guaranteeing reproducible digestions, completely unattended even overnight. A Digestion Block will relieve staff from long digestion processes and prepare samples for analysis in advance of your workday, significantly improving laboratory productivity. The solid high-grade aluminium block, encased in a stainless steel housing, ensures an acid resistant and very low maintenance block digester. Users can control temperatures, program digestion methods, pause steps and detect errors through the separate, programmable, acid resistant Controller. The addition of a Block Digester to your laboratory will reduce manual handling, improve safety, increase productivity and improve the quality of your digestions irrespective of the operator or the batch. The SEAL Analytical Digestion Block is used for a variety of applications including TKN and TP digestions on, environmental, food, pharmacy, chemistry and biochemistry samples.
