Made from either nickel plated brass or stainless steel, Cadence Science® metal stopcocks are precision-machined, individually lapped, and carefully mated to maintain pressure characteristics
All stopcocks are pressure resistant to 45 psi except the high pressure variants which are resistant up to 290 psi (20 bars). The spring clip stopcocks are designed to hold the key in position under proper sealing pressure and do not require a screwdriver in cleaning operations. Standard luer tapers include Female Luer Lock (FLL), Male Luer Lock (MLL), and Male Luer (ML).
