Rainin Classic Pipette

Rainin Classic pipettes are calibrated using Rainin tips. Performance to published specifications is guaranteed only when Rainin tips are used. Graduation marks on each Rainin tip are useful for quick volume checks.

Rainin pipettes and tips are designed together as a pipetting system. Molded from premium-grade virgin polypropylene, all Rainin tips are BioClean and totally inert, so you can be assured of the best pipetting results.

To mount a universal-fit pipette tip, press the shaft into the end of the tip with light force. The tip will seal properly on the shaft with minimal force — do not use more force than is required.

• Tips must seal properly on the shaft to assure an air-tight seal and avoid leaks or poor accuracy.
• Tips must be soft and flexible so that the shaft is not scratched or worn prematurely.
• Tips must be free from microscopic flash and particulates.
• The tip orifice must be the correct size, and orifice size and geometry must be consistent from tip to tip. Otherwise, accuracy and precision will be affected.
• Interior and exterior surfaces must be clear, smooth, and hydrophobic to avoid retention of liquid. Too much retention results in poor accuracy and reproducibility.

Genuine Rainin tips easily pass these requirements. Rainin cannot accept responsibility for poor performance resulting from the use of tips by other manufacturers.
