Research Microtools

Stem Cell microtools are used to transfer embryonic stem cells into blastocysts. They come in five sizes: 15-17μm I.D., 17-19m I.D., 19-21μm I.D., 22-24m I.D., and 24-26m I.D. The smaller sizes are typically used for stem cells of human origin while the larger stem cell micropipets are used for stem cells of mouse origin. Both have a bevel with a short, sharp spike. Other diameters are available by ordering a customized Stem Cell micropipet and specifying the desired diameter size.

Stem Cell micropipets may be ordered straight or with an angle. Angle choices are 15, 20 25, 30, 35, 40 and 45. Standard Stem Cell micropipets are bent 0.5mm from the tip of the pipet, however, you may order a customized Stem Cell micropipet angled 1mm, 1.5mm or 2.0mm from the tip.

Piezo drill micropipets are made to fit the piezo-based micromanipulator. They are often used for ICSI in mice or for the creation of transgenic animals. These are made with a blunt opening and come with any inner diameter between 5m and 20m (I.D.).

They are bent 6mm from the tip and may be ordered straight or with a 15 or 25 angle. When ordering, please specify sterile or non-sterile. Other angles are available by ordering a customized Piezo drill micropipet and including your specifications.
