A sample loop is a defined length of tubing and fittings configured to match the angle of the injection valve ports. A sample is loaded and held in the loop until injection is triggered, either automatically or manually. Stainless steel loops are supplied with unswaged fittings, so the tube can be completely bottomed in the injection port before the ferrule is swaged. The loop volumes are nominal.

Compatible with injection valve models 7725, 7725i, PR/EV700-100, PR/EV703-100, and MX Module
