Premium Denudation and Transfer Pipette

EZ-Tip is a premium quality plastic tip for oocyte denudation or oocyte and embryo handling.

Our close-tolerance plastic tips are flexible, with smooth edges and consistent geometries.

The EZ-Tip can be easily extracted from its packaging and loaded into the pipettor.

The 0.9mm outside diameter fits the EZ-Grip and is compatible with all popular denudation and transfer pipettors.

“We have been using the EZ-Tip now for over a year. We have found them to be comfortable and easy to use whilst providing the fine control required for the safe handling of oocytes and embryos. The different diameters are well suited to all the stages of the IVF/ICSI process, from oocyte denudation to blastocyst transfer. ”

Bulb Pipette Denudation and Handling System

EZ-Squeeze™ is a pipette and bulb system for oocyte denudation or oocyte and embryo handling, designed for use with a handle accessory.

The pre-assembled  EZ-Squeeze™ pipette is fitted with an aspiration bulb, creating a reliable seal, which is not always guaranteed with customer assembled systems.  This time-saving combined unit enables a faster set-up and the flexible, shatter-proof medical grade plastic pipette does not scratch Petri dishes, as fragile glass pipettes are prone to do.

EZ-Squeeze™ pipettes are supplied sterile in individually sealed packs with clear, large print and colour coded size information.  The autoclavable EZ-Squeeze™ handle, supplied separately, is designed to offer precision, ease of handling and a comfortable working position.

“We have been purchasing the EZ-Squeeze tips from RI since 2011, the tips allow precise control and secure handling during all lab procedures. We have found the RI supply chain to work flawlessly, from order placement to after sales service – even at very short notice.”

Paul Edward Wilson, Head of Embryology and Andrology, Bristol Centre for Reproductive Medicine, UK

Single-Use Denudation and Handling System

EZ-Strip is a unique registered design, developed for maintaining the most exacting laboratory sterility standards.The EZ-Strip minimises any risk of cross contamination through the use of a complete sterile unit.

Systems using reusable devices or handles cannot make the same guarantees. The EZ-Strip pipette is made of medical grade plastic which will flex and not damage the Petri dish.

Available in nine sizes, including a long version which is ideal for the handling of oocyte in tubes. The shelf life of EZ-Strip is three years.

“At CARE Fertility, we moved over to the EZ range over 12 months ago and our 30 embryologists adapted easily to them. The key reason that we switched over to them was in order to minimise scratching of dishes by glass pipettes. The range is broad and the service and support by RI is very reliable.”

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.
