Tubes and rack are autoclavable at 121°C (2 bar), acc. DIN EN 285 (cover mat/strip, TPE, not autoclavable). Tubes, racks and lids can withstand temperatures as low as -80°C. The seal of the tubes is pressure tested and there is a stable connection between the mounting plate and the racks, making these stackable racks well suited for use with robots and automated systems. Coded tubes (A1-H12) and rack sides are suitable for barcode labels. Ideal for use with robots and other automated dispensing systems.
