White Horse Scientific has announced improvements to the Capp 1000 microlitre pipettes.
The pipettes have a new tip base with a hydrophobic filter and the piston is made from stainless steel rather than aluminium.
The company said the changes would help to improve the chemical resistance of the Capp pipette and prolong its life.
Each new 1000 microlitre Capp pipette will now be supplied with the new tip base and samples of filters.
