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.

DEENA ll- For Safe, Reliable Sample Preparation & Metals Digestion

The DEENA ll is manufactured by SEAL Analytical. DEENA is part of the SEAL Sample preparation group of products that automate  chemical addition, sample preparation and digestion systems used in the analysis of mercury and metals in environmental laboratories. With DEENA you not only automate the steps involved in sample preparation you also eliminate the manual dispensing of corrosive acids and other dangerous reagents. (SEAL DEENA is branded Thomas Cain in Asia)

DEENA II is a sample digestion system that fully automates the digestion process ensuring each sample is treated exactly the same, safeguarding against human error.

DEENA II will:

  • Accurately dispense small volumes of reagents into sample tubes
  • Mix thoroughly
  • Apply heat
  • Fill to volume after digestion is completed

DEENA II Digestion System Advantages

  • Safer digestions with the elimination of manual dispensing of corrosive acid and other dangerous reagents
  • 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


SmartBlock Graphite Heating BlockSmartBlock ll is a graphite heating block that will simultaneously digest up to 60 samples and it will do it faster, simpler and safer than digestions carried out using traditional laboratory equipment. The robust construction, small footprint and economical pricing makes it ideal for small laboratories or those with limited space looking for simpler and safer digestions.

The SmartBlock ll is designed to address common digestion safety issues as well as significantly improve laboratory productivity.

SmartBlock ll Advantages

  • Fast, even heating of both the sides and base of digestion tubes
  • Heating from ambient to 180o
  • Excellent temperature stability eliminating the need to move individual digestion tubes to a more favorable position
  • Solid graphite heating block with rugged teflon coating eliminating corrosion and sample contamination
  • Chemically inert and heat resistant digestion tubes
  • Graduated, single use, flat bottom digestion tubes not only optimise heat transfer, they eliminate the need for digestion beakers, volumetric flasks, storage containers, graduated cylinders etc
  • Minimised heat transfer to surrounding workspace
  • Designed to significantly reduce required sample volume, chemicals used, digestion time and power consumption
  • Built-in safety features to protect samples and operators
  • Simple to use
  • Reproducible results
