 This is the transfer cap only, shaker flasks are sold separately

Nest Scientific aseptic transfer caps allow for the convenient transfer of liquid in and out of Erlenmeyer flasks which greatly reduces the risk of contamination. The cap comes with pre-assembled tubing, connectors and gas exchange filters for convenience. 

The multifunction caps offer additional parts to improve on the simpler bi-directional design:

• The cap features a built in hydrophobic membrane for enhanced gas exchange. This means the shaker flask can be place directly into an incubator, no need to change vessels.
• The external transfer tube features a T-junction with a one way Luer lock sampling valve. This allows small samples to be removed for testing. It also solves the problem of liquid remaining in the tubing after use. Simply attach a Luer lock syringe and draw off the excess liquid. 
• A larger, barbed hydrophobic filter that can be attached to a vacuum or pump source.
