Design Changes

Nordson MEDICAL has recently made design enhancements to our PharmaLok™ line of tube clamps. The changes not only improve performance, but they also make end-user interaction more consistent across the product line.

A guide was inserted into the tube clamps to control how the two halves close on tubing. Although it didn't impact shutoff operation, prior to the change, the upper and lower halves could shift slightly. Now, they remain lined up when closed.
