Valco Replacement Rotor for 4 Port C4WE Type Valves
- Rotor Material: Valcon E
- Maximum Pressure: 400 PSI Gas
- Maximum Temperature: 225C
- Typical Product Lead Time: 3-4 weeks
Valcon E: A polyaryletherketone/PTFE composite, the E material receives wide GC use in what had previously been a problematic gap between the optimum temperature ranges of P and T, and in HPLC applications where the temperature requirement is higher than what can be handled by the H material and where a lower pressure limit can be tolerated. (Standard specs are 400 psi at 225?C, but higher pressure ratings are possible at reduced temperatures.) However, this polymer cannot be used in prolonged contact with high concentrations of sulfuric and nitric acids, DMSO, THF, or liquid methylene chloride.
