ProSeal™ is a family of Closed System Transfer Devices (CSTD) that mechanically prohibits environmental contaminants from entering the system and the escape of drug aerosols from the system, thereby minimizing operator and patient exposure to drug aerosols during compounding and patient drug administration.


ProSeal™ CSTD seals the contents and opens a fluid path through an embedded needle only when the assembly is connected to a ProSeal™ CSTD component. Contents are never exposed and there is no residue after administration.
ProSeal™ CSTD is compliant to NIOSH Requirements to reduce the risk of exposure to hazardous drugs.
ProSeal™ Injection Site and all its corresponding interface membranes exhibit 100% efficiency in achieving a dry connection in the communicating surfaces in a fluid transfer.
Microbial Ingress testing verifies container closure integrity for product sterility. ProSeal™ CSTD reliably prevents microbial ingress of at least 168 hours (7 days).
The ProSeal™ Vial Adaptor ensures pressure equalization when connected to a drug vial.
This prevents the generation of fine aerosols that could expose the environment, patients, and healthcare professionals to hazardous drugs, which may occur due to pressure differences.
Our comprehensive range of CSTD accessories elevate safety standards for healthcare professionals and patients alike.

ProSeal™ is a family of closed system transfer devices (CSTD) designed to ensure safe transfer of drugs. ProSeal™ CSTDs guarantee 100% operator and patient safety from pharmacy compounding to patient administration.

Toxiseal™ Vial Adaptor ensures the safe transfer of drugs by preventing drug aerosols from escaping and prohibits environmental contaminants from entering the system.
