Real-World Testing: Putting Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 250 to the Test
First Use Experience
My first test of the Kimble/Kontes KIMAX Dispensing Burets, Straight Bore PTFE Stopcock, Kimble Chase 17080F 250 was at my workbench, preparing a cleaning solution for my firearms.
