Make sure you read about and test both our classic pipettor families:

The pipette is made of medical grade plastic, which will flex and not damage the Petri dish
We have tested EZ-Tip® with the commonly-used denudation pipettors with a 0.9 outer diameter. EZ-Tip® is intended as a high quality replacement for other brands.
EZ-Tip® pipette tips and all popular pipette tips with a 0.9mm outer diameter.
The EZ-Grip® may eventually require a replacement plunger wire and ‘O’ rings after extended use. These can be ordered from RI. One set is supplied with the unit.
Supplied with the EZ-Grip®is a M2.5 hex key tool that is needed to loosen and replace the plunger wire. No tools are required to replace the seal.
We believe we use higher quality component parts to minimise maintenance requirements.
It is compatible with handles with a 4mm inner diameter. However, a EZ-Squeeze™ handle is supplied as required.
It is compatible with pipettes with a 1.5mm outer diameter with a bulb with a 4mm outer diameter.
As a single-use system, EZ-Strip® minimises the risk of cross-contamination, which is of paramount importance in assisted reproduction.
RI has an environmental policy and it limits waste as much as possible. Clinics may consider that the benefits of minimising the risk of cross-contamination outweigh environmental concerns of additional packaging of a single-use item.
The pipette is made of medical grade plastic, which will flex and not damage the Petri dish.
Once a multipack is opened the sterility of each unit is compromised. With individual packaging, the sterility of each EZ-Strip® is guaranteed.
