RI Biopsy Micropipettes
RI Biopsy micropipettes (B) are used to remove tissue from embryos or oocytes for pre-implantation genetic diagnosis (PGD).
RI offers these micropipettes in three profiles – flat, non-spiked or spiked.
Available in a range of ID sizes suitable for a variety of biopsies including polar body (usually 14µm ID), blastomere and trophectoderm biopsies (usually between 20-40µm ID).
Each biopsy micropipette is fire polished to minimise damage to the cell membrane.
RI Assisted Hatching Micropipettes
RI assisted hatching micropipettes (AH) are used to direct acidic solution (acid tyrodes) onto the zona pellucida to thin the zona or create a hole to enable the embryo to hatch.
RI Injection Micropipettes
RI ICSI injection micropipettes can be used to immobilise, then inject spermatozoa into the cytoplasm of an oocyte during ICSI and intracytoplasmic morphologically-selected sperm injection (IMSI).
Our ICSI injection micropipettes are designed for the smoothest control of sperm injection and cytoplasm suction, and to minimise damage to the oocyte. Multiple sperm can be loaded and injected.
Injection micropipettes from RI are available with a spike (SI) or without a spike (NI) and in 2 different glass thicknesses – 1µm (standard) or 0.9µm (thin – T code).
For human ART, the larger 8µm ID injection micropipette is ideal for collecting sperm from a testicular tissue sample prior to ICSI and is only available in thin (T code) glass.
RI Zona Dissection Micropipettes
RI zona dissection micropipettes (MD) are used to mechanically cut an opening in the zona pellucida of an oocyte or embryo to enable assisted hatching and biopsy. The micropipette is designed with a sharp tip and a strong taper section for easy control and precise manipulation.
RI Holding Micropipettes
These micropipettes are designed for anchoring the oocyte or embryo during ICSI or other micromanipuation procedures.A smooth fire polished tip cradles the cells gently and securely. 32µm large holding micropipettes are available with a 30° and 35° bend angle.
