/£ Kn Never lose or denature a gel filtration sample again. L D C / C h e m i n e r t Teflon couplings, tube end fittings, adapters and connectors permit you to neatly mate various sizes of t u b i n g and connect Teflon to glass or plastic fittings. Finger tightened connections are all that are necessary to make a chemically inert, leak-free liquid transfer system at pressures to 500 psi. L D C / C h e m i n e r t glass and Teflon columns further ensure that samples will be pure w h e n eluted. Chemically inert sample injectors and pulse-free C M P pumps, w i t h zero dead v o l u m e f l o w passages, perfectly layer precise q u a n tities of sample at the t o p of the c o l u m n for m a x i m u m t h r n n p h n u t in m i n i m u m timp t h r o u g h p u t in m i n i m u m time.
