Cloning cylinders, made of glass, light brown(tinted). Individual colonies of transfected cells can be isolated and picked from a plate containing many clones. Isolated clones can be dissociated and passaged free from surrounding cells or pulsed with 50 to 100 µl growth medium which can be analyzed for secreted products. The sterile cloning cylinders are greased on one end to allow the cylinder to seal to the plate. Cells are then dissociated within the cylinder, resuspeneded, and transferred to a new vessel as a pure colony.

• Sterlized by electron-beam irradiation
• Display a brown tint after being sterlised at the appropriate dosage level
