PhaSeal Closed System Transfer Devices

PhaSeal is the closed system transfer device (CSTD) that set the standard for safe handling of hazardous drugs in oncology pharmacies and infusion settings. Developed to protect pharmacists, nurses, and clinicians from exposure to cytotoxic and other hazardous medications, the PhaSeal system creates a mechanically and airtight barrier during compounding, transport, and administration.

If you're evaluating CSTDs for USP <800> compliance, the question usually comes down to how well a system contains vapor, aerosol, and liquid at every connection point. PhaSeal uses a double-membrane, needle-based design that keeps drug and air pathways fully enclosed—no venting to the surrounding air, no leakage at connection or disconnection. That "dry connection" approach is why many hazardous drug safety programs standardize on it.

Where PhaSeal Fits in a Hazardous Drug Workflow

A complete PhaSeal setup spans the full path of a hazardous drug: a protector locks onto the drug vial, an injector or luer-lock adapter connects to the syringe, and connectors bridge to IV bags and administration sets. Because each component mates only with the others, the closed pathway is maintained from reconstitution in the pharmacy hood through bedside administration and disposal. Facilities typically stock the components that match their most common drug volumes and delivery methods.

Buyers in this category are usually building toward compliance and staff protection rather than a single purchase, so it helps to think in terms of the full system—vial access, syringe transfer, and infusion connection—rather than individual parts. Matching component compatibility and vial-neck sizes to your formulary avoids gaps in containment.
