Racks are ideal for use below 4°C (39.2°F)

Note: Autoclavable, but repeated autoclaving may reduce mechanical strength.

They are made of transparent, rustproof, and corrosion-resistant polycarbonate. Holes are keyed with numbers and letters for easy identification. Wide spacing allows convenient insertion and removal of tubes. Racks stack when empty for convenient storage. Will not float in water baths.
