Boehringer Ingelheim Steel Rack for Microcentrifuge Tubes 36 Place 10.5 mm Dia.

The Boehringer Ingelheim 500091 is a heavy-duty 36-place microcentrifuge tube rack constructed from high-grade stainless steel, designed for superior durability and chemical resistance in demanding laboratory environments. Unlike plastic alternatives, the steel construction of this rack ensures it can withstand extreme temperature fluctuations, making it ideal for use in ultra-low temperature freezers, water baths, or for repeated sterilization cycles in an autoclave. The rack is configured in a compact grid to hold up to 36 individual tubes, providing an organized footprint for high-throughput sample processing or storage.

Technically, each of the 36 wells features a 10.5 mm diameter, which is precision-sized to accommodate standard 1.5 mL and 2.0 mL microcentrifuge tubes (Eppendorf-style). The wells are typically designed with a "stepped" or "open-bottom" geometry to ensure that tubes sit securely without wobbling, while allowing for maximum surface area contact with cooling or heating media. This rack is particularly valued in molecular biology and clinical research workflows where sample integrity is paramount and the risk of plastic degradation or rack buoyancy in water baths must be eliminated. The polished steel surface is non-porous and easy to decontaminate, meeting the stringent hygiene requirements of diagnostic and pharmaceutical laboratories.

Used; excellent condition.
