Abstract
A device for aspirating sample media into a pipette for use in a micro-manipulation procedure includes a ring member having an opening sized for receiving a digit of an operator, and an aspirating bulb engaged with the ring member. The aspirating bulb has an open end sized for receiving an end of the pipette, and includes a compressible chamber capable of creating a suction force suitable for aspirating the sample media into the pipette. The aspirating bulb is oriented along the ring member such that the chamber is compressible by a digit on the same hand of the operator as the digit receivable in the ring member.
