Our high quality, Stainless Steel Sample Loops are specifically designed for valve models 8125/8126. They have burr-free, square-cut ends to ensure a flush connection to valve ports and are supplied with unswaged fittings. The two ends of the loop must be completely bottomed in the injector ports before the ferrule is swaged onto the loop. These loops are available in volumes 5µL,10µL, 20µL and 50µL.
