Title: Cell sediment swab - made of cellulose wadding inside specified plastic membrane bag esp. narrow weave nylon fibres membrane
IPC: C12M1/26
Filed: 1989-07-27
Abstract: A transfer swab for the cell sediment sepd. in a centrifugal tube is a spherical bulb at the end of a glass tube and consists of a porous membrane.  This exerts a suction on the residual liq. in the cell sediment after the decantation of the settled liq. The pores of the membrane are impermeable for the cell components; the membrane is pref. a narrow weave of nylon fibres in the shape of a bag. In an embodiment, the cell sediment (15) at the bottom end (12) of a centrifugal tube (11) is picked up by a glass tube (18) with a bag (5), made of a nylon membrane (19) and filled with cellulose wadding (6) to act as a suction chamber. The glass tube is inserted with slight turning movements (16) to extract the residual liq.; the sediment will adhere to the bag for easy extn. ADVANTAGE - This picks up and transfers cell sediment without damage from the bottom of a centrifugal tube independent of the skill of the operator.
