Micro Centrifuge Tubes are small-volume laboratory tubes used for sample preparation, centrifugation, storage and routine liquid handling. This range includes non-sterile polypropylene tubes with conical-bottom and round-bottom formats for different laboratory workflows.
The conical-bottom design helps direct suspended material towards the lower end of the tube during compatible centrifugation, while round-bottom tubes provide a smooth internal profile for general sample handling and mixing. Users should confirm tube capacity, rotor and adapter compatibility, maximum permitted RCF and sample requirements before use.
These tubes are manufactured from polypropylene. ISO 19069-2 specifies methods used to determine the properties of polypropylene moulding and extrusion materials, while ASTM D4101 provides a classification system for polypropylene materials used in moulding and extrusion. Chemical compatibility should always be checked against the actual reagent and operating conditions, with ASTM D543 providing recognised procedures for evaluating the resistance of plastics to chemical reagents.
As these products are identified as non-sterile, they should not be used where a sterile tube is specifically required unless they undergo a separately validated sterilisation process. For LabChoice Australia customers, Micro Centrifuge Tubes provide practical polypropylene options for research, education, quality control and routine small-volume sample processing.
