BD50 & BD28 Digestion Block

The 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.

• Small footprint, allows bench top placement and saves fume hood space
• Automates the digestion process and frees up laboratory personnel
• Reliable and repeatable automation with every sample treated exactly the same
• No cross contamination
• No direct contact with sample or vial
• Even heating of every sample
• Time saving features such as overnight digestions and standby "warm" feature to rapidly bring samples up to digestion temperature
• Suitable for EPA approved methods
• Durable- constructed to reliably run in the harsh digestion environment it operates in
• Real-time reporting and sample tracking
• Intuitive & completely customizable software
• Commonly used methods are pre-loaded

DEENA ll is Ideal For:

• Reliable metals digestions
• Reliable Total Phosphorous and Nitrogen digestions

SmartBlock ll- Graphite Heating Block

For Trace Metal Digestions SOILS - SLUDGES - DRINKING WATER - WASTEWATER

SmartBlock ll Advantages

• Fast, even heating of both the sides and base of digestion tubes
