Ohaus Dry Bath Heat Block 5 x 50 ml Conical Tube Rack

OHAUS Modular Dry Block Heater Insert, 5 x 50 mL Conical Centrifuge Tubes (30400168)

The OHAUS 5 x 50 mL Conical Centrifuge Tube Modular Block (30400168) is a high-precision, solid anodized aluminum dry bath insert engineered for uniform heating, temperature retention, and sample stability. Designed for seamless integration into OHAUS HB Series Dry Block Heaters and Incubating Cooling Orbital Shakers, this single-module block securely accommodates up to five standard 50 mL conical bottom centrifuge tubes. Machined with high-precision wells to maximize tube-to-wall surface contact, the block minimizes thermal resistance and ensures rapid, reproducible heat distribution across all samples. Outfitted with an integrated thermometer well for independent temperature validation, this modular accessory provides reliable performance across a broad spectrum of molecular biology, clinical diagnostic, and analytical workflows.

Technical Performance & Structural Attributes

• Solid Anodized Aluminum Construction: Crafted from high-density aluminum with an anodized finish that resists chemical exposure, rust, and surface corrosion during high-temperature incubations.
• Precision-Machined Tube Wells: Deep 29 mm diameter wells contoured to close tube-to-wall tolerances, ensuring efficient thermal conductivity and uniform heat retention.
• Integrated Thermometer Well: Features a dedicated vertical monitoring bore for external temperature sensors, RTD probes, or stem thermometers to verify actual sample block temperatures.
• Modular Interchangability: Standard single-block footprint allows tool-free insertion and removal from multi-block heating units for quick assay reconfiguration.
