Graduated, single-use syringe locks – only from Tulip.
Unlike other Syringe Snapper Locks the Tulip Johnnie Snap™ does not need the the plunger to be pulled all the way out before it activates, allowing for a more controlled negative pressure.
These syringe snap locks fit into the plunger flanges of the syringe. As the plunger is pulled out the lock snaps open on the barrel lip holding the syringe under vacuum.
Supplied in a box of 10 units , the Johnnie Snap is available for both 20cc and 60cc syringes and fits both Monoject and BD syringes.
