Custom Logo PP Plastic Transfer Pipettes 0.2-10ml Graduated Pasteur Pipettes

To aspirate, gently squeeze the elastic bulb to expel air, insert the precision tip into the liquid, and slowly release the bulb. This creates a vacuum that draws the liquid into the barrel up to the desired volume marking. Avoid releasing the bulb too quickly to prevent splashing or overfilling.

Position the pipette tip over the target vessel at a slight angle. Slowly and steadily squeeze the bulb to push the plunger down, releasing the liquid drop by drop or in a stream. For complete emptying, compress the bulb fully until all liquid is expelled.

Yes, the smooth internal bore design facilitates the flow of slightly viscous liquids. However, for highly viscous samples, a wider-bore pipette or positive displacement pipette may be more efficient. Our graduated pipettes work well for most standard aqueous and organic solutions.

Plastic Pasteur pipettes offer superior safety (no breakage), convenience (no cleaning required), and cost-effectiveness. They eliminate the risk of glass shards contaminating samples and reduce labor costs associated with washing and sterilizing glassware.
