VWR Digital Dry Bath Dual Block Heater

VWR Advanced Digital Dry Bath Dual Block Heater (75838-282)

The VWR 75838-282 Advanced Digital Dry Block Heater is a high-precision, microprocessor-controlled laboratory thermal platform designed for a broad spectrum of temperature-critical assay procedures. Configured to accommodate two modular, interchangeable aluminum heating blocks, this compact instrument delivers uniform and repeatable temperature environments. Its advanced digital electronics optimize the unit for enzyme reactions, sample incubation, immunoassays, DNA denaturation, and general culture melting protocols requiring strict temperature stability.

Technical Performance & Design

• Microprocessor PID Temperature Regulation: Driven by an intelligent internal PID control algorithm that delivers exceptional temperature stability of ±0.1°C and optimal cross-block temperature uniformity.
• Dual-Block Layout Efficiency: The 2-block layout maximizes multi-sample throughput within an economical laboratory footprint, permitting operators to mix and match varied tube adapter sizes side by side.
• Integrated Touchpad Controls with Dual Displays: Features an intuitive, low-profile touchpad control interface with separate, easy-to-read LED digital displays for monitoring both temperature and time metrics simultaneously.
• External Temperature Probe Interface: Built-in electronic socket supports an optional external RTD temperature probe kit (such as VWR 11301-112), enabling the unit to regulate heating based on the actual fluid temperature inside a sample vial.

Key Benefits & Applications

• High-Wattage Rapid Heating: Engineered with internal cartridge heaters that ramp the block platform to target temperatures rapidly, minimizing wait times during high-throughput workflow preparations.
• User Safety Interlocks: Equipped with a prominent visual "Hot" warning indicator light that remains illuminated whenever the block platform surface temperature rises above 40°C, protecting laboratory staff from contact burns.
• Onboard Calibration Mode: Features an accessible single-point calibration interface, allowing quality assurance managers to align digital readouts directly with certified reference thermometers for GLP/GMP standard tracking.
• Rugged Laboratory Longevity: Encased in a powder-coated, chemical-resistant steel housing with a heavy-duty anodized aluminum block well to isolate heating circuits from accidental sample spillage.

Used, tested to be in great working condition.
