Aseptic Disconnector

Short Description:

LePure Biotech’s aseptic disconnector can quickly achieve aseptic disconnection and ensure system sterility at both ends of the tubing. It is used in combination with an aseptic disconnecting ring. Sterility is achieved by preventing the entrance of external microorganisms during disconnection and effectively protecting the liquid from the external environment without needing tubing sealers or tubing clamps.
