Used Sanwa Chemical test tube rack holds 50 tubes of 16.5mm diameter, ideal for laboratory sample organization.
This Sanwa Chemical Test Tube Rack model 447 is designed for secure holding of up to 50 laboratory test tubes with a diameter of 16.5 mm each. Commonly utilized in biotechnology labs, clinical diagnostics, and molecular biology for organizing samples during procedures such as bioprocessing and gene editing, this rack facilitates efficient sample processing and storage. Being a used laboratory accessory sold as-is, the rack may have limitations in functionality compared to new units; verification prior to use is recommended. The test tube rack’s durable design supports standard tube diameters used in molecular diagnostics workflows and is ideal for labs requiring organized containment of multiple samples simultaneously.
