Brand: SP Scienceware
Features:
- Tetrahydrofuran (THF) which is widely used as a mobile phase for GPC, attacks the CTFE components
- Viton O-rings of the standard CHROMWARE systems
- THF-resistant version of the five valve integrated system are shown below
Wilmad-LabGlass
Details: These CHROMWARE five valve cap systems include a five valve cap to facilitate recycling in the mobile phase. Direct membrane filtration into the mobile phase reservoir avoids transfer losses and contamination by airborne particulates. Gas tight ETFE valves effectively contain helium within the reservoir, therefore, dry, deoxygenated mobile phases are maintained for chromatographic separations. 1/4" -28 flangeless fittings allow for easy connection to pumps or other system components. Tetrahydrofuran (THF), which is widely used as a mobile phase for GPC, attacks the Viton O-rings of the standard CHROMWARE. The only changes required to make an economy system THF-resistant are replace the standard inlet filters with all-stainless-steel inlet filters (BP-1916-621), and the Viton O-ring at the base of the three hole cap with a size 216 Kalrez O-ring (BP-1240-026).
