Environmental Express Manual HotBlocks

Simplify and Improve Metals Prep in Your Laboratory

For 25 years Environmental Express HotBlocks® have been the answer for laboratories seeking faster, cleaner, more cost-effective methods of performing metals digestions. Environmental Express are continually expanding their line of metals digestion products in an effort to meet the growing needs of the environmental laboratory community. 

Superior Design and Materials Consistently Provide Reliable Results

HotBlocks® come in a variety of configurations to meet the needs of your laboratory. From the smallest to the most complex all blocks are crafted from the finest materials and designed with the rigors of the laboratory environment in mind. All HotBlocks® are made from PTFE-coated graphite and other non-metallic materials virtually eliminating corrosion and the sample contamination that corrosion may cause.

• The heater mat in each block provides uniform heat distribution to all samples throughout the digestion process. Heat surrounds the digestion vessels completely, requiring less energy and radiating less heat than acid digestion with hot plates.


• All blocks are capable of maintaining a setpoint of ±0.1°C and provide sample consistency of ±1.5°C. Temperature stability allows all samples being digested to evaporate at a similar rate, providing more uniform recoveries and preventing the opportunity for cross contamination.


• All blocks are protected by the SafeSample® alarm feature. In the unlikely event of a runaway temperature situation, an audible alarm sounds and electrical power to the heater mat is interrupted.
