Micro Pestles
Micro pestles are used for grinding and homogenising small biological or chemical samples directly within micro tubes. Their compact design ensures efficient sample disruption and preparation.
Made from durable, chemical-resistant plastic, micro pestles are suitable for single-use or repeated laboratory applications.
Australian laboratories depend on micro pestles for consistent and effective small-scale sample processing in research and teaching environments.

Micro Pestles are small polypropylene grinding tools used for manual sample grinding, crushing, and homogenising in microcentrifuge tubes. This pack includes autoclavable micro polypropylene pestles for 1.5 mL and 0.5 mL tubes, making them practical for small-volume sample preparation in teaching laboratories, research benches, biology labs, and routine preparation areas.
The compact pestle shape allows users to work directly inside compatible microtubes, helping reduce sample transfer steps and minimise material loss during preparation. These pestles are useful for soft tissue disruption, pellet resuspension, small sample grinding, and general microtube-based preparation where a simple manual homogenising tool is preferred.
Polypropylene construction provides a lightweight, durable, and chemical-resistant option for everyday laboratory handling. The autoclavable format supports reuse where suitable cleaning and sterilisation procedures are followed according to the laboratory’s method and the manufacturer’s instructions. Users should always confirm compatibility with the sample type, tube size, chemical exposure, and sterilisation conditions before use.
For best results, the pestle should be matched to the correct tube size and used with controlled pressure to avoid damaging the tube or losing sample material. After use, pestles should be cleaned, inspected for wear or contamination, and handled according to the laboratory’s sample preparation and hygiene procedure.
For material and quality reference, ASTM D4101 covers polypropylene materials for moulding and extrusion applications, while ASTM D543 is relevant to evaluating plastic resistance to chemical reagents. ISO 17665-1 provides sterilisation guidance for moist heat processes, which may be relevant where autoclaving procedures are used. These references support the material, chemical resistance, and sterilisation context only, and should not be used as product-specific compliance claims unless supported by manufacturer documentation.
For LabChoice Australia customers, Micro Pestles provide a practical small-volume sample preparation accessory for Australian laboratories, schools, universities, research facilities, and preparation rooms needing autoclavable polypropylene pestles for 1.5 mL and 0.5 mL microtube workflows.
