As the majority of pipettes are variable volume how can you ensure that a pipette is linear across it’s specification range by testing only one volume?
Always ask what level of service you are getting for your money. A. If you apply grease to the internal parts of a pipette, it will need to be removed with a solvent for cleaning during servicing. The amount of grease re-applied may vary and could alter the calibration of the pipette. Dry-seal pipettes maintained in the correct way, should never require grease to be applied. They can be cleaned and seals and O-rings replaced without altering the calibration. Anachem always replaces these critical dry-seal parts during servicing to maintain high levels of accuracy and precision. Other service agencies who do not use quality spare parts or who wish to reduce costs, rather than replacing parts, may use grease to obtain an air-tight seal. Grease may harbour contaminants within the pipette, introduced through aerosols or when pipetting volatile liquids. These are retained in the grease and may advance corrosion of internal pipette parts such as pistons. Such damage may increase costs as add
