Availability
These products are available for sale in Europe, the USA, Canada and Australia, as well as selected countries in the rest of the world.
The EZ-Range of denudation and handling devices is mouse embryo assay (MEA) and Limulus amoebocyte lysate (LAL) tested and made from flexible and shatter-proof medical-grade plastic, designed to avoid scratching Petri dishes (as fragile glass pipettes are prone to do).
All products are rigorously checked for quality, ensuring consistent geometries, close tolerances, and smooth edges, and are sterilized in compliance with ISO 11137 standard for gamma irradiation.
Good to know
The use of EZ-Tips, EZ-Strips or EZ-Squeeze tips for denudation of the oocyte helps to minimize the duration of exposure to additional chemicals such as the hyaluronidase enzyme.1,2
The use of the EZ-Tips, EZ-Strips or EZ-Squeeze tips may help facilitate improved fertilization rates by aiding the mechanical removal of the cumulus-corona radiata complex from around the oocyte, improving oocyte visibility for the user, and allowing injection of spermatozoa during ICSI procedures without the cumulus cells blocking the ICSI needle.1,2
General questions about the EZ-Range™ portfolio
The EZ-Range portfolio includes both traditional pipetting (EZ-Grip, EZ-Tip), bulb pipetting (EZ-Squeeze) and a complete sterile single-use unit (EZ-Strip) to fulfill most ART laboratories’ demands.
EZ-Grip has a blow-out capacity to remove the remaining liquid in the tip, which can reduce the risk of oocytes and embryos getting stuck in the pipette tip. EZ-Squeeze and EZ-Strip are both bulb pipettors with a closed tip system, and EZ-Strip additionally is a complete sterile single-use unit, which reduces the risk of cross-contamination between patient samples, for example high viral impact patients. Tip vials and blister packs are color marked which will reduce the risk of using a tip diameter which is too small for the purpose, posing mechanical stress to the oocyte or embryo.
EZ-Range is designed for denudation of oocytes in preparation for ICSI and IVF techniques. The EZ-Range devices can also be used for handling or moving oocytes and embryos from one container to another, for example between drops in a dish, between dishes or moving to a vitrification carrier. The devices are also approved to handle biopsied material for PGT, such as polar bodies, blastomeres and trophectoderm cells.
EZ-Grip™ Pipettor
- Easy and quick tip assembly: simply push the tip onto the plunger wire – no need to unscrew the collet
- Straightforward ergonomic design – comfortable to use for long periods
- Smooth plunger for precise control
- Requires minimal maintenance
- Cleanliness: The equipment can undergo ultrasonic cleaning and be sterilized using an autoclave
- Blow-out capacity to remove the remaining liquid in the tip
Tip size indicator
Manual indicator dial may be used as a reminder of the size of the EZ-Tip fitted (or left blank if preferred)
This can be beneficial during oocyte denudation when multiple size diameters might be used
Volume adjustment
Adjust the volume according to the procedural need, for example large volumes for oocyte denudation and small volumes for vitrification or tubing of cells. One turn equates to approximately 0.2µL.
Comfort Grip (optional)
Ergonomic accessory which helps reduce the strain caused by repetitive pipetting and enables pipette free standing.
Cleanliness

Maintenance Made Easy
If a pipettor is not properly maintained, it may create workflow disruptions and frustration.
With our maintenance video the process of caring for your EZ-Grip device is simplified, making maintenance straightforward and accessible for all users. You can also read this in the Instructions for Use provided with the product.
The EZ-Grip may eventually require a replacement plunger wire and seals after extended use. These can be ordered as separate repair kits. One set is supplied with the unit. Please see the above maintenance video.
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 seals.
EZ-Squeeze™ Pipette
EZ-Squeeze™ Tips
- Save time – pre-assembled with bulb for faster set-up,
ensuring a reliable seal - Individually packed for sterility
- Shelf life of five years
- Color coded – for easy identification
EZ-Squeeze™ Handle
Designed to offer precision aspiration and ease of handling
Designed for a comfortable working position, allowing the hand to rest on the working surface
It is compatible with handles with a 4mm inner diameter for the bulb.
EZ-Strip® Pipette
EZ-Strip is a unique design, developed for maintaining the most exacting laboratory sterility standards.
The EZ-Strip is a complete sterile unit for denudation and handling which reduces the risk of cross contamination.1
Systems using reusable devices or handles cannot make the same guarantees.
- One complete sterile unit – designed as a pipettor handle and pipette in one to reduce the risk of cross-contamination between patient samples
- Bulb pipetting – for precise volume control
- Color-coded – for easy identification
- Test tube lid forms the pipettor handle. The lid can be used to close the unit again after use
- Designed for a comfortable working position, allowing the hand to rest on the working surface
As a single-use system, EZ-Strip™ minimizes the risk of cross-contamination which is of paramount importance in assisted reproduction.
Clinics may consider that the benefits of minimizing the risk of cross-contamination outweigh the environmental concerns of additional packaging of a single-use item.
The pipette tip 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 maintained.
