Your valuable probes are in good hands with the centrifuge tubes from TPP!
Features of the TPP centrifuge tubes surpass ordinary tubes. They are:
manufactured with highest grade of raw material fulfilling requirements of USP Class VI
white writing circle, affixed on the screw cap, for easy labeling with any writing instrument
caps that cannot be over-tightened
gas and aerosol tight cap
graduations all the way down to 0.1 ml / 0.5 ml respectively
convenient racks available that are autoclavable and are collapsible for storage when not in use
The TPP centrifuge tubes are manufactured on automatic transport units. This guarantees that the products are carefully moved to the next work station within the manufacturing line quick and without unnecessary contamination risk.
Sub-operations such as printing, on-screwing of closure caps or tests for tightness are then performed in clean-room conditions.
