Pribolab EQ5010-2 High-Performance Oil-Free Vacuum Pump

Overview

The Pribolab EQ5010-2 is a compact, oil-free diaphragm vacuum pump engineered for precision and reliability in analytical laboratory environments—particularly those supporting regulated food safety testing workflows. Unlike rotary vane or scroll pumps, this unit operates on positive displacement via an elastomeric diaphragm actuated by a low-noise, brushless DC motor. Its design eliminates lubricant contamination risk, ensuring inert gas handling and compatibility with solvent-laden vapors commonly encountered during sample preparation for mycotoxin analysis (e.g., acetonitrile-, methanol-, or toluene-based extractions). With an ultimate vacuum level of 0.0085 MPa (8.5 mbar), the EQ5010-2 delivers sufficient suction head for applications including vacuum filtration, solid-phase extraction (SPE) manifold operation, vacuum concentration of eluates, and degassing of mobile phase solvents prior to HPLC or LC-MS analysis. Its stable, pulse-dampened flow profile supports reproducible loading across multi-well immunaffinity columns (e.g., Aflatoxin B1/G1/B2/G2, Zearalenone, or Ochratoxin A IACs) without column channeling or resin compaction.

Key Features

• Oil-free diaphragm technology ensures zero hydrocarbon carryover—critical for trace-level mycotoxin quantification where background interference must be minimized.
• Adjustable pumping speed via integrated electronic control enables fine-tuned vacuum pressure modulation, optimizing flow rates for diverse SPE cartridges (e.g., PuriToxSR series) and IACs without compromising binding efficiency or recovery.
• Low power consumption (20 W) and thermally managed motor design support continuous unattended operation during high-throughput sample batches—consistent with GLP-compliant laboratory practices.
• Compact footprint (245 × 135 × 245 mm) and lightweight construction (3.2 kg) allow flexible benchtop integration, including placement beneath fume hoods or inside analytical instrument enclosures.
• Chemically resistant wetted materials (EPDM diaphragm, PTFE valves, stainless steel housing) provide long-term stability when exposed to common organic solvents used in mycotoxin cleanup (e.g., acetonitrile, methanol, acetone, ethyl acetate).

Sample Compatibility & Compliance

The EQ5010-2 is routinely deployed in laboratories performing AOAC Official Method® and ISO/IEC 17025-accredited analyses for regulated mycotoxins—including aflatoxins (B1, B2, G1, G2, M1, M2), ochratoxin A, zearalenone, deoxynivalenol (DON), fumonisins (B1, B2), T-2/HT-2 toxins, and patulin. Its vacuum performance aligns with method requirements for vacuum-assisted sample loading in multi-toxin purification workflows (e.g., PuriToxSR M160, T220, F120 columns), where consistent 15–25 kPa differential pressure ensures complete eluate transfer while preserving column integrity. The pump meets CE safety directives (2014/30/EU EMC, 2014/35/EU LVD) and complies with RoHS 2011/65/EU restrictions on hazardous substances. While not intrinsically rated for explosive atmospheres, its non-sparking motor and absence of oil make it suitable for use in standard analytical labs handling Class I, Division 2 solvent vapors under NFPA 30 and local fire codes.

Software & Data Management

As a standalone mechanical device, the EQ5010-2 does not incorporate embedded firmware or digital connectivity. However, its operational parameters—including runtime, pressure setpoints, and duty cycle—are fully compatible with external lab data management systems via analog 0–10 V or 4–20 mA vacuum transducer interfaces (optional add-on). When integrated into automated SPE workstations or vacuum manifold systems, it supports audit-trail generation per FDA 21 CFR Part 11 requirements when paired with validated electronic lab notebooks (ELNs) or LIMS platforms. No proprietary software is required; calibration and maintenance logs may be recorded manually or imported into existing QA/QC documentation frameworks aligned with ISO/IEC 17025 Clause 7.7 and GLP Principles.

Applications

• Vacuum-assisted loading of immunaffinity columns (IACs) for aflatoxin, zearalenone, and ochratoxin A in grain, feed, and dairy matrices.
• Parallel processing of PuriToxSR multi-toxin cleanup columns (M160, T220, O130) during LC-MS/MS method validation studies.
• Degassing of HPLC mobile phases containing acetonitrile/water or methanol/water blends to prevent bubble formation in UHPLC systems.
• Concentration of purified mycotoxin extracts using nitrogen-assisted vacuum concentrators (e.g., TurboVap®-compatible setups).
• Supporting ELISA plate washing steps requiring controlled vacuum aspiration across 96-well plates in high-volume screening labs.

FAQ

Is the EQ5010-2 suitable for continuous operation in 24/7 analytical labs?

Yes—the brushless DC motor and thermal protection circuit enable uninterrupted duty cycles up to 8 hours per session, provided ambient temperature remains below 35°C and ventilation is adequate.
Can this pump handle corrosive vapors from acid digestion or halogenated solvents?

No. While chemically resistant to common polar organics (acetonitrile, methanol, acetone), it is not rated for hydrochloric, nitric, or chloroform vapors. Use only with solvents listed in the PTFE/EPDM compatibility chart.
Does the adjustable pumping speed affect ultimate vacuum performance?

No. Speed adjustment modulates flow rate only; ultimate vacuum (0.0085 MPa) remains constant across all settings, verified per ISO 21360-1:2020 calibration protocols.
What maintenance intervals are recommended for routine GLP compliance?

Diaphragm and valve replacement every 6,000 operating hours or annually—whichever occurs first—with full service log entry per ISO/IEC 17025 Clause 6.4.2.
Is the pump compatible with third-party vacuum manifolds used for IAC processing?

Yes. Standard 8 mm barbed or 1/4″ NPT inlet/outlet ports ensure seamless integration with commercially available SPE vacuum manifolds (e.g., Supelco, Thermo Fisher, Waters).
