SFC Chromatography Solution – JASCO SCF-VCH-BP | 6-Valve Change Unit Series
Where This Product Is Used
The JASCO SCF-VCH-BP TAB22A-4/PURF2-LF 6-Valve Change Unit is a precision flow-path switching component engineered for Supercritical Fluid Chromatography (SFC) and Supercritical Fluid Extraction (SFE) systems. It is deployed in environments where rapid, reproducible column or solvent switching is critical to throughput and analytical accuracy.
- Pharmaceutical R&D labs – chiral separation, impurity profiling, and method development
- Natural product extraction – CO₂-based extraction of cannabinoids, terpenes, and botanical compounds
- Food & beverage QC – fat-soluble vitamin and lipid analysis under supercritical conditions
- Environmental testing labs – trace contaminant screening with minimal solvent waste
- Chemical synthesis support – online reaction monitoring in flow chemistry setups
- Academic & government research – high-pressure fluid system studies requiring multi-column configurations

Why Engineers Specify This Model
- Zero dead-volume switching – the TAB22A-4 actuator delivers repeatable, leak-free valve actuation at SFC operating pressures (up to 400 bar)
- PURF2-LF seal chemistry – low-friction PTFE formulation resists CO₂ swelling and organic modifier degradation, extending service intervals
- Drop-in OEM compatibility – direct replacement for JASCO SFC-4000 series without system reconfiguration
- Validated sub-assemblies – 2L81-000001-14 and 2L81-050039-41 are factory-matched and tested as a unit
- Ultra-low power draw – 396 µW standby rating supports 24/7 automated lab operation without thermal interference
- Traceable catalog references – dual catalog codes (4022.454.71615 / 5517D-C19) simplify procurement across global JASCO distributors

Application-Specific FAQ
Q: Is this unit compatible with the JASCO SFC-4000 series?
A: Yes. The SCF-VCH-BP is the OEM valve change unit for the SFC-4000 platform. Confirm your system’s back-pressure regulator configuration before ordering.
Q: Can the PURF2-LF seals handle methanol/ethanol co-solvents?
A: Yes. PURF2-LF is rated for common SFC modifiers including MeOH, EtOH, IPA, and ACN at standard SFC operating temperatures (30–60 °C).
Q: What is the expected service life of the valve seals?
A: Under normal SFC operating conditions (≤300 bar, ≤60 °C), PURF2-LF seals typically achieve 50,000–100,000 actuation cycles before replacement is recommended.
Q: Do you supply the 2L81-000001-14 and 2L81-050039-41 sub-assemblies separately?
A: Yes, subject to availability. Contact us with your specific sub-assembly requirement.
Q: Is a calibration certificate included?
A: A factory test certificate is included. Third-party calibration can be arranged upon request for ISO 17025 environments.
