Increase fluid flow with our large-bore (Larger Lumen) connectors. A standard luer has a restriction of about 0.095 inch
(2.4 mm). Qosina large-bore connectors have a minimum ID of 0.138 inch (3.5 mm), 50% larger than the standard luer.
Our large-bore connectors are designed to bond into 0.197 inch (5 mm) ID tubing. Up to 5 times the flow rate of a luer.
For more viscous fluids, we also offer extra large-bore connectors to bond into 0.236 inch (6 mm) ID tubing.
With a 0.165 inch (4.2 mm) minimum ID, the flow rate is up to sixteen times that of a standard luer.
Super large-bore connectors have a 0.28 inch (7.1 mm) minimum ID designed to bond onto or into 0.315 inch (8 mm) ID
or OD tubing, allowing for an even faster flow.
Poiseuille’s Law:
The volume of a fluid flowing through a tube varies as the fourth power of the diameter of the tubing, or, V=D

, other things
being equal. The following formula determines rate of flow:
High-Flow Large-Bore Connectors permit faster delivery of viscous fluids and minimize risk of
connection errors between incompatible fluid systems
