The smooth, non-reactive internal bore of the PEEKsil Injection Loop by SGE reduces sample carry-over and sample rinse times. Another advantage of PEEKsil Injection Loops is reduced sample loss due to shear or adsorption. Maximum operating pressures are 3000psi for 10µL, and 20µL loops. Compatible with most valves, such as Rheodyne and Valco.
