Cleaning And Decontamination - VWR International VWR 10 Instruction Manual

How to lubricate the piston (except VWR10)
Use only VWR lubricant (delivered inside the pipette box).
Squeeze a small quantity from the tube onto a clean, lintless cloth. Use the cloth to transfer the
lubricant to the piston. Ensure that the piston is evenly lubricated and that you wipe away any
excess – remember only a fine film of lubricant is required (over the entire piston).
Maintenance operation for multichannel models
For multichannel models, the lower part should not be disassembled: only the Push-button, the
connecting nut and the tip-ejector can be replaced.
 Changing the tip-ejector
To remove the tip-ejector, keep both ejector locks depressed. Pull the tip-ejector down.
To refit the tip-ejector, gently re-insert the tip-ejector vertically into the rails of the ejector support.
Pull lightly on the tip-ejector to check the position.

CLEANING AND DECONTAMINATION

VWR Electronic Pipette is designed so that the parts normally in contact with contaminants can
easily be cleaned and decontaminated.
If you use chemical solutions for decontamination or detergents for cleaning, other than those
specified below, you should check with your supplier that the solution or detergent is safe for use
with one of the following materials: PP (Polypropylene), PBT (Polybutylene Terephthalate), PC
(Polycarbonate), POM (Polyoxymethylene), PVDF (Polyvinylidene Fluoride), PEI (Polyetherimide)
and stainless steel.
Cleaning
The pipette must be cleaned, as described below, before it is decontaminated. For cleaning
VWR Electronic Pipette you may use a simple soap solution, Ethanol or Isopropanol or broad
spectrum disinfectants.
Single channel models
- External
1/ Remove the tip-ejector for cleaning (refer to chapter 13).
2/ Replace the elastomer plug to protect battery charging port.
3/ Wipe the entire pipette with a soft-cloth or lint-free tissue impregnated with soap solution, to
remove all dirty marks. If the pipette is very dirty, a brush with soft plastic bristles may be used.
Use alcohol (ethanol or isopropanol) to clean
