ILMVAC WOB-L Vacuum Piston Pump 2562C-50

Overview

The ILMVAC WOB-L Vacuum Piston Pump 2562C-50 is a compact, oil-free reciprocating piston vacuum pump engineered for precision laboratory applications requiring clean, contamination-free vacuum generation. Unlike rotary vane or diaphragm pumps, the WOB-L design employs a patented oscillating piston mechanism with PTFE-coated sealing elements and self-lubricating bearings—enabling true dry operation without lubricants, hydrocarbons, or maintenance-intensive oil changes. This architecture ensures consistent ultimate vacuum performance down to 12 mbar (absolute), making it suitable for degassing solvents, vacuum filtration, sample preparation under reduced pressure, and low-vacuum drying processes. Its robust cast-aluminum housing, vibration-damped mounting, and thermally stable motor winding support continuous duty cycles at ambient temperatures up to 40 °C, while maintaining acoustic emissions below 52 dB(A)—a critical factor in shared lab environments where noise-sensitive instrumentation or personnel comfort is prioritized.

Key Features

• Oil-free dry-running reciprocating piston mechanism with PTFE-sealed oscillating piston and ceramic-coated cylinder bore for long-term seal integrity and zero hydrocarbon outgassing
• Integrated analog vacuum/pressure gauge with dual-scale readout (mbar and psi) for real-time process monitoring without external sensors
• Built-in adjustable vacuum regulator valve enabling precise control of suction pressure across the operational range (12–1000 mbar)
• Factory-installed buffer bottle with sintered stainless-steel inlet filter to prevent particulate ingress and condensate backflow
• Compact footprint (381 × 254 × 254 mm) and lightweight construction (7.5 kg) facilitating benchtop deployment, mobile cart integration, or field use in QA/QC labs
• Thermally protected 250 W asynchronous motor with IP54-rated enclosure, compliant with IEC 60034-1 and EN 60034-30 efficiency standards
• Standard 7 mm male BSP exhaust port compatible with flexible silicone or fluoropolymer tubing; optional G1/4″ adapter kit available

Sample Compatibility & Compliance

The 2562C-50 is chemically compatible with common laboratory vapors including water, ethanol, acetone, ethyl acetate, and low-concentration organic solvents—provided condensable loads remain within the buffer bottle’s thermal capacity (≤ 50 mL/h liquid equivalent). It is not rated for corrosive gases (e.g., HCl, Cl₂, NH₃), halogenated solvents (e.g., chloroform, DCM), or explosive atmospheres. The pump meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. While not intrinsically safe, its design supports integration into GLP-compliant workflows when paired with validated vacuum manifolds and documented calibration procedures per ISO/IEC 17025. No oil vapor carryover eliminates risk of sample contamination—a key requirement for analytical sample prep prior to GC, HPLC, or mass spectrometry analysis.

Software & Data Management

As a standalone mechanical vacuum source, the 2562C-50 does not incorporate digital controllers or embedded firmware. However, its analog vacuum gauge output (0–1000 mbar linear scale) is compatible with third-party data acquisition systems via optional 4–20 mA or 0–10 V transducer modules (sold separately). When integrated into automated vacuum manifolds, it supports audit-trail-capable logging when used with FDA 21 CFR Part 11–compliant SCADA platforms. Routine verification of ultimate vacuum performance can be performed using calibrated capacitance manometers traceable to NIST standards, with documented calibration intervals recommended every 12 months or after 2000 operating hours.

Applications

• Vacuum-assisted filtration of aqueous and organic solutions using Buchner or Hirsch funnels
• Removal of dissolved gases from HPLC mobile phases and calibration standards
• Low-temperature solvent evaporation in rotary evaporator secondary traps
• Pre-conditioning of desiccators and glove boxes prior to inert gas purging
• Support vacuum for small-scale lyophilization pilot runs (primary drying only)
• Gas sampling and blank preparation in environmental and pharmaceutical QC laboratories

FAQ

Is the 2562C-50 suitable for high-vacuum applications?

No—it is designed for rough vacuum service (12–1000 mbar); for pressures below 1 mbar, a secondary pump (e.g., turbomolecular or diffusion pump) is required.
Can it handle solvent vapors continuously?

Yes, provided condensables are trapped upstream and total liquid load remains ≤ 50 mL/h; prolonged exposure to high-boiling-point solvents may accelerate seal wear.
Does it require periodic oil changes?

No—its dry-running design eliminates all lubrication requirements; only visual inspection of the buffer bottle and inlet filter is recommended before each use.
What is the expected service life under continuous operation?

With proper ventilation and ambient temperature control ( 15,000 hours MTBF based on ILMVAC’s accelerated lifetime testing per DIN EN 60068-2-64.
Is a calibration certificate included with shipment?

A factory-verified ultimate vacuum test report (at 23 °C, 50% RH) is supplied; NIST-traceable calibration certificates are available upon request with additional lead time.
