Cook® Precision Micro-Injection Pipettes

Used for the intracytoplasmic single-sperm injection of oocytes.

Pipettes specifically designed for precision sperm control with well-defined bevels to aid zona pellucida puncture. These pipettes are supplied in two main groups: the Classic "1" and the Precision "3" series. The Precision "3" series pipettes have parallel walls to better control sperm movements, while a stiff, spiked tip facilitates easy insertion through the zona pellucida. A longer bevel length provides more precise injection.
