For single use
Box of 5

The patented GEMS™ Johnnie Snap syringe locks for 60 cc and 20 cc are designed to maintain a vacuum at various pressure levels, from low to high. Thanks to a newly designed piston clamp, this lock forms a single unit with the piston, allowing vacuum to be built up effortlessly. The Johnnie Snap provides a stepwise, low-pressure vacuum with 2 locking positions for 20-cc syringes and 3 locking positions for 60-cc syringes.
