What Is StabiliX™ — and Why It Matters
- Dual‑stage, moulded design for consistency and durability: According to the company, StabiliX™ is engineered to provide “stress‑free operation with consistency, reliability, and long life for any degassing application where dissolved gases and bubbles are problematic.”
- Compatible with a wide range of degassers: The pump works with both modern film‑based degassing chambers and traditional membrane/tubular designs, and is fully retrofittable — including to Biotech Fluidics’s full range of inline degassers (the DEGASi® family).
- Analytical and preparative scale available: The analytical-scale version is suited for standard degassing chambers and typical fluids, while the preparative-scale version is designed to handle high vapor loads — useful when dealing with high flow-rate degassing chambers or solvents with low vapor pressure that can cause increased solvent pervaporation.
- Flexible mounting: Pumps are offered in both bottom‑ and side‑mounted configurations, giving labs and instrument builders flexibility when integrating into existing fluidic systems.
Technical Highlights at a Glance
- Wetted path materials include 316 stainless steel, PTFE, PEEK, glass-filled PPS, EPDM, and borosilicate glass — making the pump compatible with a broad range of solvents and buffers.
- Vacuum performance (closed-loop):
- Analytical pump: ~50 mmHg vacuum at ~60 rpm with ~3 SCCM air flow.
- Preparative pump: ~80 mmHg vacuum at ~80 rpm with ~3 SCCM air flow.
- Continuous purge ensures that the pump head remains free of solvent vapour, and built-in anti-backflow valves prevent vacuum loss even in case of power failure.
- Compliance with current regulations: The StabiliX™ pumps are claimed to conform to RoHS and REACH directives.
Why Lab Managers Should Consider Upgrading to StabiliX™
If you currently rely on inline degassers — for example for HPLC mobile phases, flow chemistry, or sample preparation — upgrading to StabiliX™ can bring several operational benefits:
- Long-term reliability: The dual-stage, stepper‑motor driven design minimizes wear, noise, heat generation, and vacuum hysteresis — all of which contribute to extended pump lifetime and stable degassing over time.
- Better solvent compatibility and safety: The inert wetted path and robust materials ensure safe operation even with organic solvents and challenging mixtures — important for labs working with diverse chemistries.
- Flexibility in workflows: With both analytical and preparative versions — and bottom or side mounting — StabiliX™ can be integrated into new systems or retrofitted into existing ones, giving you flexibility depending on scale and configuration.
- Reduced maintenance headaches: The continuous vacuum control, purge design, and anti-backflow valves reduce the need for frequent pump changes or troubleshooting, saving you time and downtime.
Integration with DEGASi® Inline Degassers — A Full Degassing Solution
StabiliX™ is designed to work seamlessly with the full family of Biotech Fluidics’s inline degassers (DEGASi®), which use a gas-permeable membrane plus constant vacuum control to extract dissolved gases from fluid streams.
This compatibility makes it easier for labs to standardize on a degassing platform — whether they work at microliter per minute flows or high preparative flow rates. The upgrade path is also facilitated by an online “vacuum pump replacement finder” for replacing obsolete pumps and control boards, even from other brands.
Conclusion
For labs that depend on precise fluid handling — be it chromatography, flow chemistry, or automated sample prep — the new StabiliX™ vacuum pump from Biotech Fluidics represents a significant step forward in ensuring stable, long-term degassing performance. Its durability, flexible configuration options, and compatibility with the broad DEGASi® degasser range make it a strong choice for both new instrument designs and retrofits.
