Designed for seamless integration into OHAUS HB Series Dry Block Heaters and Incubating Cooling Orbital Shakers, this single-module block securely holds up to 12 standard 12 mm outer diameter tubes (such as 12 mm blood collection tubes, test tubes, or 1.5 mL\/2.0 mL microcentrifuge tubes). Machined with deep, precision-contoured wells to maximize surface contact with tube walls, this insert minimizes thermal resistance and guarantees consistent heat distribution across all positions. Outfitted with an integrated thermometer well for independent temperature validation, this modular block is an essential consumable accessory for clinical chemistry, molecular biology, and routine diagnostic testing.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Structural Attributes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSolid Anodized Aluminum Construction: Manufactured from high-density, aircraft-grade aluminum with an anodized surface that resists chemical spills, rust, and surface degradation during high-temperature incubations.\u003c\/li\u003e\n\u003cli\u003ePrecision-Machined Tube Wells: Deep 12.7 mm diameter wells contoured to tight tolerances, delivering optimal conduction and uniform heat transfer across all sample positions.\u003c\/li\u003e\n\u003cli\u003eIntegrated Thermometer Well: Features a dedicated vertical monitoring bore for external temperature sensors, RTD probes, or stem thermometers to verify actual sample block temperatures.\u003c\/li\u003e\n\u003cli\u003eModular Tool-Free Interchangability: Standard single-block footprint allows easy placement and removal from multi-block heating units for quick assay reconfigurations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCatalog \/ Part Number: 30400172\u003c\/li\u003e\n\u003cli\u003ePrimary Manufacturer: OHAUS Corporation\u003c\/li\u003e\n\u003cli\u003eSample Vessel Compatibility: 12 mm Outer Diameter Tubes (12 mm test tubes, culture tubes, blood collection tubes)\u003c\/li\u003e\n\u003cli\u003eCapacity \/ Number of Wells: 12 Wells\u003c\/li\u003e\n\u003cli\u003eWell Diameter: 12.7 mm (0.50 in)\u003c\/li\u003e\n\u003cli\u003eWell Depth: 47.6 mm (1.88 in)\u003c\/li\u003e\n\u003cli\u003eBlock Dimensions (L x W x H): 3.75 x 3.0 x 2.0 inches (9.5 x 7.6 x 5.1 cm)\u003c\/li\u003e\n\u003cli\u003eMaterial Composition: Anodized Aluminum\u003c\/li\u003e\n\u003cli\u003eSystem Compatibility: OHAUS HB Series Dry Block Heaters (1, 2, 4, and 6-block models) and Incubating Cooling Orbital Shakers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eClinical \u0026amp; Diagnostic Assays: Ideal for incubation of 12 mm blood tubes, coagulation testing, serum incubation, and enzyme-linked assays.\u003c\/li\u003e\n\u003cli\u003eMolecular Biology \u0026amp; Nucleic Acid Prep: Provides uniform heating for sample incubation, enzyme inactivation, restriction digests, and ligation reactions.\u003c\/li\u003e\n\u003cli\u003eIsothermal Heating Safety: Eliminates the mess, evaporation risks, and water-borne contamination hazards associated with traditional liquid water baths.\u003c\/li\u003e\n\u003cli\u003eHigh Heat Retention: Dense aluminum alloy acts as a thermal mass, maintaining stable temperature levels even during brief transfers between benchtop instruments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eAll product names, logos, and brands are property of their respective owners.
