Thermo Scientific 4 Block Digital Drybath

Thermo Scientific 4-Block Digital Dry Bath / Touchscreen Block Heater (88870003)

The Thermo Scientific 4-Block Digital Dry Bath (88870003) is a high-capacity, precision laboratory block heater engineered for uniform thermal incubation of biological samples across a wide range of vessel formats. Featuring a modular aluminum heating chamber that accommodates up to four interchangeable modular block inserts, this system provides exceptional temperature accuracy, stability, and uniformity from ambient plus 5 degrees C up to 130 degrees C. Controlled via an intuitive digital touch-pad interface with an LED display, the 88870003 allows precise temperature adjustments in 0.1 degree C increments and features an integrated digital timer (up to 99 hours, 59 minutes). Built with a built-in temperature sensing probe and an optional external RTD temperature sensor interface, this dry bath is an essential benchtop system for high-throughput sample preparation, enzyme reactions, nucleic acid denaturation, and immunoassays.

Technical Performance & Structural Attributes

• High-Capacity 4-Block Modular Chamber: Holds up to four interchangeable anodized aluminum blocks to accommodate microcentrifuge tubes, PCR plates, test tubes, or 96-well plates simultaneously.
• Microprocessor Digital Temperature Control: Delivers precise heating control with dual digital displays showing real-time actual temperature and user setpoint parameters.
• High Temperature Uniformity & Stability: Anodized aluminum heating chamber and close-tolerance heating elements ensure consistent heat distribution ($\pm 0.2$ degrees C uniformity at 37 degrees C) across all block positions.
• Integrated PID Digital Timer & Alarms: Programmable countdown timer with audible completion signal enables precise incubation duration management from 1 minute up to 99 hours and 59 minutes.
• External Temperature Probe Interface: Compatible with external PT100 RTD sensor probes for direct, real-time monitoring of sample fluid temperatures inside the vessel.
