  • General Troubleshooting – Liquid Leak Test Testing & 12 Point Pipette Inspection

    Liquid Leak Test

    A simple liquid leak test will help determine if a pipette sealing system (i.e. piston, seal, shaft, o-ring, and tip) is working as it should, and may uncover hidden problems not seen to the naked eye.

    12 Point Pipette Inspection

    The information provided in the table below will help identify pipette parts and components that could require replacement or be causing underlying concerns that may not be seen to the naked eye. Routine pipette inspection checks (at least monthly) will aid in keeping your pipettes performing optimally.

    Note: The picture below is a RAININ Pipet-Lite. For most parts, it will provide visual clarity and guide for different manufacturer pipette models in the market. Inspection of the seal, o-ring, piston assembly, and shaft may require that the pipette calibration be re-verified after a minimum equilibration period of 1- hour has passed. The equilibration period is needed to allow the pipette to conform, contract, and adapt back to ambient laboratory temperature.

  • Electronic Pipette Error Message

    Electronic Pipette Error Message

    All motorized electronic pipettes have an onboard program to control the performance of each pipetting action. An error message on the display means that the pipette has not been able to perform the attempted action properly. It could be due to an unfit component, like the tip, or the incorrect action of the operator.  In any event, the display will show “Error” and “Press Ent”. All that the user needs to do is to clear the message and reset the pipette. The procedure to clear the error and reset is either on the display, such as “rst”, or in the manufacturer user manual.

    In most cases, clearing the electronic pipette error message and resetting the pipette will fix the issue.  However, if something has gone wrong with the printed circuit board or the motor, it can be only replaced by the manufacturer due to the need of propriety software only the manufacturer has access to.

  • Repairing Pipette Controllers

    There are many brands of pipette controllers with names such as Pipet-Aid, FastPette, Accu-jet pro, S1 Pipet Filler, Easypet, etc.  These are simple instruments with two functions: aspiration and dispensing.  How much sample to take-up or push-out is controlled by your finger and there is no calibration adjustments on these units. The glass or plastic pipette tube has graduated marks imprinted on them for the direct aspiration, dispensing, and transferring of liquids. There is no need to calibrate these units.

    The top three issues that these instruments face are:
    Clogged filter: 

    Pipette controllers all use a special filter designed to block any liquid.  If a user holds the trigger longer than needed and the sample aspirates beyond the capacity of the pipette tube, the filter shuts the entrance off to prevent the sample from entering the mechanical chamber and damage the instrument. Install a new filter to solve this problem.

    Dead battery:

    Replace the battery if it will not recharge or hold a charge. Use the manufacturer’s wall power supply for best results and battery life.

    Dislocated internal tubing / hoses:

    Trauma to the controller, such as a fall, can cause one or more of the internal tubing ends to become dislodged. Hoses are also susceptible to cracking. These issues are indicated when the instrument appears working when the trigger is pulled, but no sample is aspirated. This repair should be entrusted to a service person to ensure proper evaluation and reassembly.
