Inoculating loops with needles - Polystyrene (PS)

Sterilised, for semi-quantitative determination of bacteria from biological liquids or for transferring individual colonies. Easily disposed of after use by autoclaving or incineration. This means maximum security for the laboratory with no risk of infection, since the need for heat sterilisation is eliminated. The loops are made to very tight tolerances. Recalibration may however be required in individual cases due to the different media and the pick-up and smearing technique.
