Are you struggling with inconsistent sample digestion or slow, cumbersome heating methods that bottleneck your water analysis workflow? Achieving precise, reproducible digestion is critical for accurate COD, nutrient, and metals analysis, yet traditional hot plates and baths can introduce variability and safety risks. The Hach DRB200 Digital Reactor Block is engineered to solve these exact challenges, providing a controlled, reliable, and efficient heating platform for your most demanding sample preparation protocols. This robust digital reactor block standardizes the digestion process, ensuring your results are dependable, batch after batch, while streamlining your laboratory workflow.

Why Choose the DRB200 Digital Reactor Block? Solving Inconsistency, Safety & Efficiency Challenges

Achieve flawless sample preparation with intelligent features that directly address common analytical laboratory pain points.

• Eliminate Inconsistent Digestion for Reliable Analytical Data: Fluctuating temperatures and uneven heating lead to variable results. This precision laboratory reactor offers unmatched process control with a temperature range of 37°C to 165°C adjustable in 1°C increments. Its rapid heating technology brings the block from 20°C to 150°C in under 10 minutes, ensuring every vial in the 15-position block experiences identical, stable conditions for highly reproducible digestion efficiency.

• Ensure Operator and Sample Protection at All Times: Open heating elements and hot surfaces pose burn risks and contamination hazards. The DRB200 digestion block is engineered with multiple layers of safety, including a fully insulated heater block, integrated temperature safeguards, and locking, transparent lids that deter premature opening and contain potential splashes. An end-of-run audible alarm with automatic shutdown prevents over-digestion, protecting both the user and sample integrity.

• Accelerate Workflow with Intuitive, One-Key Operation: Complicated programming wastes valuable time. The DRB200 COD reactor features unique one-key operation with pre-loaded programs for standard Hach digestion procedures (COD, TOC, Test 'N Tube). It also stores up to three user-defined methods for specialized protocols, significantly reducing training time and the potential for operational errors.

• Maximize Versatility and Conserve Bench Space: Why purchase multiple heaters for different vial sizes? This single, compact unit accommodates both 16 mm vials (for COD, TOC) and 20 mm vials (for metals preparation), making it a versatile hub for sample preparation. This consolidates multiple heating needs into one reliable instrument, optimizing valuable bench space.
