IKA VACSTAR digital Digital Vacuum Pump

Overview

The IKA VACSTAR digital is a high-performance, oil-free diaphragm vacuum pump engineered for precision and reliability in demanding laboratory environments. Based on a four-stage diaphragm architecture, it delivers stable, pulse-free vacuum generation across low-vacuum applications—typically ranging from atmospheric pressure down to ≤ 2 mbar absolute. Its core design eliminates lubricating oils, ensuring contamination-free operation critical for solvent evaporation, rotary evaporation, filtration, freeze drying, and vacuum distillation workflows. The pump employs PTFE-coated or fully PTFE-composite diaphragms and gas-path components, granting exceptional resistance to aggressive organic solvents, acids, and bases—making it suitable for chemistry, pharmaceutical, and analytical laboratories where chemical compatibility and long-term durability are non-negotiable. Unlike single- or dual-stage alternatives, the four-stage configuration enables higher compression ratios and improved ultimate vacuum performance while maintaining low noise emission (54 dB(A)) and compact footprint (W 150 × H 375 × D 370 mm).

Key Features

• Four-stage diaphragm pump architecture for enhanced vacuum stability and deeper ultimate vacuum (≤ 2 mbar)
• Infinitely variable speed control (285–1200 rpm) via intuitive rotary encoder, with real-time LED digital rpm display
• Oil-free, dry-running operation ensures zero hydrocarbon contamination and eliminates maintenance associated with oil changes or mist separation
• Chemically inert gas path: PTFE diaphragms, valves, and internal surfaces compatible with acetone, chloroform, methanol, HCl, and other corrosive vapors
• Integrated USB interface enables direct communication with IKA’s Labworldsoft software for remote parameter setting, data logging, and protocol-driven operation
• Built-in analog output port (0–10 V) and included analog control cable support seamless integration with the optional VC10 Lite vacuum controller for closed-loop pressure regulation
• Optional VSE1 secondary cold trap enhances solvent recovery efficiency and reduces emissions—critical for GLP-compliant labs handling hazardous or regulated substances
• Low-noise design (54 dB(A)) and compact vertical form factor optimize benchtop space without compromising thermal management or service access

Sample Compatibility & Compliance

The VACSTAR digital is validated for continuous operation with volatile organic compounds (VOCs), aqueous solutions, and mildly acidic/basic vapors under standard ambient conditions (5–40 °C, non-condensing). Its PTFE-based construction complies with ISO 8573-1 Class 0 (oil-free air) requirements for contaminant-free vacuum generation. While not certified to ATEX or IECEx standards for explosive atmospheres, its design aligns with general laboratory safety best practices outlined in ANSI Z9.5 and EU Directive 2006/42/EC (Machinery Directive). For regulated environments, the pump supports audit-ready operation when paired with Labworldsoft’s 21 CFR Part 11-compliant software modules (with electronic signatures and full audit trail functionality). It meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU).

Software & Data Management

The integrated USB interface allows native communication with IKA Labworldsoft—a modular, Windows-based platform supporting multi-device orchestration. Users can configure ramp profiles, set target vacuum levels, log rpm and runtime data at user-defined intervals (down to 1-second resolution), and export CSV-formatted reports for QA documentation. When connected to the VC10 Lite controller, Labworldsoft enables dynamic pressure feedback loops, enabling adaptive speed modulation based on system load—essential for reproducible rotary evaporation or controlled drying cycles. All software operations generate timestamped, immutable logs compliant with GLP and GMP documentation standards. Firmware updates are delivered via secure HTTPS download through IKA’s official support portal.

Applications

• Routine and preparative rotary evaporation of heat-sensitive compounds
• Vacuum-assisted filtration (e.g., Büchner, sintered glass, membrane filtration)
• Freeze drying (lyophilization) pre-evacuation and primary drying stages
• Gas sampling and inert atmosphere purging in glove boxes or Schlenk lines
• Thin-film deposition and vacuum desiccation of hygroscopic materials
• Environmental analysis workflows requiring VOC-trap integration (e.g., EPA Method 502.2, 8021B)
• QC/QA labs performing USP or compliant sterilization validation studies

FAQ

Is the VACSTAR digital suitable for use with aggressive solvents such as THF or concentrated nitric acid?
Yes—the entire wetted path, including diaphragms, valves, and chamber surfaces, is constructed from chemically resistant PTFE or PTFE composites, validated for intermittent exposure to common organic solvents and diluted mineral acids. Continuous exposure to hot, fuming nitric acid is not recommended.
Can the pump be operated continuously for 24/7 applications?
It is rated for continuous duty under specified ambient conditions (5–40 °C) and load profiles consistent with ≤ 2 mbar ultimate vacuum. Thermal protection circuitry automatically interrupts operation if internal temperature exceeds safe thresholds.
Does the USB interface support third-party SCADA or LabVIEW integration?
IKA provides an open ASCII command protocol over USB virtual COM port; LabVIEW drivers and Python SDKs are available upon request from technical support.
What maintenance is required during the 3-year warranty period?
No scheduled maintenance is required. Diaphragm replacement is only necessary after ≥ 10,000 hours of cumulative operation or if vacuum performance degrades below specification—typically beyond 3–5 years under normal lab use.
Is the VSE1 secondary condenser unit required for compliance with local environmental regulations?
While not universally mandated, the VSE1 significantly reduces solvent emissions and supports adherence to OSHA PELs, EU REACH SVHC reporting, and institutional EH&S policies governing VOC release in enclosed laboratory spaces.
