VACUUBRAND® VACUU·PURE 10C Dry Screw Vacuum Pump

Overview

The VACUUBRAND® VACUU·PURE 10C is a chemically resistant, oil-free dry screw vacuum pump engineered for demanding laboratory and pilot-scale applications requiring absolute hydrocarbon-free vacuum generation across the rough to medium vacuum range (atmospheric pressure down to 0.005 mbar). Unlike conventional oil-lubricated or diaphragm pumps, the VACUU·PURE 10C employs a non-contacting, dynamically balanced twin-screw architecture with precisely machined, PEEK-encapsulated rotors and stator housing. This design eliminates mechanical wear, oil contamination, and carbon-based outgassing—ensuring process integrity in sensitive chemical synthesis, solvent recovery, glovebox evacuation, and vacuum drying of moisture- and oxygen-sensitive compounds. Its ability to handle condensable vapors—including aggressive solvents and corrosive gases—without gas ballast, cold traps, or intermediate condensation stages makes it uniquely suited for continuous, maintenance-light operation in regulated environments.

Key Features

• True oil-free operation with zero hydrocarbon carryover—certified compliant with ISO 8573-1 Class 0 for compressed air purity, directly transferable to vacuum system cleanliness requirements.
• Chemically inert wetted surfaces: All gas-path components—including rotor shafts, stator bore, and inlet/outlet manifolds—are fully encapsulated in high-performance polyetheretherketone (PEEK), providing exceptional resistance to halogenated solvents, strong acids, bases, and reactive vapors.
• Non-contacting screw technology ensures zero wear under normal operating conditions, delivering stable performance over >20,000 hours without scheduled replacement of rotating parts.
• Integrated regeneration mode enables rapid post-process drying of internal surfaces via controlled backflow of dry nitrogen or ambient air—reducing turnaround time between batches and minimizing residual solvent retention.
• No gas ballast required: Capable of pumping up to 100% saturated solvent vapor loads at elevated inlet pressures (up to 500 mbar) without performance degradation or increased noise, eliminating the efficiency penalty typical of gas-ballasted diaphragm or scroll pumps.
• Compact footprint and low-vibration operation: Engineered for benchtop integration into fume hoods, gloveboxes, and automated vacuum systems without structural reinforcement or acoustic shielding.

Sample Compatibility & Compliance

The VACUU·PURE 10C is validated for use with volatile organic compounds (e.g., THF, DCM, acetone, DMF), corrosive gases (e.g., HCl, Cl₂, SO₂, NH₃), and reactive intermediates encountered in pharmaceutical process development and materials science. Its PEEK-sealed architecture meets ASTM D4541 (adhesion testing) and ISO 14644-1 Class 5 cleanroom compatibility when installed with appropriate filtration. For regulated QC/QA laboratories, the pump supports audit-ready operation under GLP and GMP frameworks: its deterministic performance profile, absence of consumables (e.g., oil changes, membrane replacements), and traceable operational parameters (via optional analog/digital I/O) facilitate 21 CFR Part 11–compliant data logging when integrated with validated SCADA or LIMS platforms.

Software & Data Management

While the base VACUU·PURE 10C operates as a stand-alone unit with manual on/off control and status LED indicators, optional analog voltage (0–10 V) and digital RS-485 Modbus RTU interfaces enable seamless integration into centralized vacuum management systems. These interfaces support real-time monitoring of motor current draw (proxy for load condition), runtime accumulation, and thermal status—enabling predictive maintenance scheduling and batch-level vacuum log generation. When paired with VACUUBRAND’s VACUU·VIEW software (sold separately), users gain access to trend analysis, alarm configuration, and exportable CSV reports aligned with ALCOA+ data integrity principles.

Applications

• High-purity vacuum drying of APIs and battery electrode slurries where residual hydrocarbons or metal ions must be excluded.
• Front-stage pumping for turbomolecular or cryogenic high-vacuum systems—eliminating oil backstreaming risks during bake-out or vent cycles.
• Continuous solvent removal in rotary evaporation and short-path distillation setups handling thermally labile or polymerizable feedstocks.
• Evacuation of Schlenk lines and inert-atmosphere gloveboxes processing air-sensitive organometallics or perovskite precursors.
• Industrial R&D scale-up of thin-film deposition processes requiring stable, particle-free vacuum below 10⁻² mbar.
• Environmental testing chambers simulating low-humidity, high-vacuum storage conditions for aerospace-grade composites.

FAQ

Does the VACUU·PURE 10C require routine oil changes or filter replacements?

No—its dry screw mechanism contains no lubricating oil, seals, or consumable membranes. Only periodic inspection of inlet particulate filters (if installed upstream) is recommended.
Can it be used as a backing pump for turbomolecular pumps?

Yes—its ultimate vacuum of 0.005 mbar and stable pumping speed above 10⁻¹ mbar make it suitable as a clean, oil-free forepump for TMUs requiring <1×10⁻⁴ mbar base pressure.
Is PEEK encapsulation sufficient for HF or fluorine gas exposure?

PEEK offers broad chemical resistance but is not rated for anhydrous hydrogen fluoride or elemental fluorine. Consult VACUUBRAND’s chemical compatibility matrix for specific concentration/temperature limits.
How does regeneration mode function?

Upon shutdown, the controller reverses flow direction briefly while introducing dry purge gas—evaporating condensed volatiles from rotor surfaces and preventing polymerization or salt deposition.
What electrical safety certifications does it hold?

The unit complies with IEC 61000-6-3 (EMC emission), IEC 61000-6-2 (immunity), and carries CE, UKCA, and EAC markings for laboratory use in EU, UK, and Eurasian Economic Union markets.
