Hach DRB200-1: high-performance dry block thermostat for laboratory digestion
The Hach DRB200-1 is designed to meet the needs of laboratories requiring reliable and controlled digestion prior to the analysis of key parameters. This model is specially adapted for 16 mm cuvettes and can accommodate 9 cuvettes and 2 reaction vessels simultaneously. Its compact and robust design allows it to fit easily on a workbench while ensuring optimal safety thanks to effective insulation and an overheating protection device.
It is easy to use thanks to a large, easy-to-read display and single-key operation for standard digestions. Pre-set programmes cover a wide range of common analyses, but the temperature and time can also be freely configured for specific requirements, offering welcome flexibility in the laboratory.
Versatility and compatibility with multiple applications
The DRB200-1 is compatible with various analytical parameters, including chemical oxygen demand (COD), total nitrogen, total phosphorus, heavy metals (lead, cadmium, copper, iron, nickel, zinc), total chromium, total organic carbon (TOC) and trihalomethanes. With heating capabilities ranging from 37°C to 150°C and an adjustable time range of 1 to 480 minutes, it can be adapted to many protocols. Predefined programmes facilitate quick preparation, while the ability to programme specific conditions allows for complete customisation for non-standard methods.
This versatility makes it an essential tool for environmental laboratories, industrial facilities, research centres and academic institutions that regularly perform analyses requiring a prior digestion step.
Reliability, safety and ease of use
The temperature stability of the DRB200-1 (±1 °C) guarantees reproducible results and compliance with EN, ISO and EPA standard methods. Rapid temperature rise – reaching 150 °C in just 10 minutes – optimises processing time. Two transparent lids protect against splashes while allowing samples to be viewed during heating.
To enhance user safety, the device is equipped with an integrated overheating protection system, and its insulated outer casing reduces the risk of accidental burns. Its intuitive operation, combined with a clear and easy-to-read display, simplifies daily operations even for inexperienced personnel.
Combining precision, safety and ease of use, the DRB200-1 is a reliable choice for any analytical routine involving thermal digestion steps.
