IKA VACSTAR lite Variable-Speed Diaphragm Vacuum Pump

Overview

The IKA VACSTAR lite is a compact, variable-speed, oil-free diaphragm vacuum pump engineered for precision-controlled vacuum generation in modern analytical and preparative laboratory workflows. Designed around a brushless DC motor and electronically regulated speed control, it delivers stable, pulse-free suction across a wide operational range—from rough vacuum down to 9 mbar ultimate pressure—without requiring oil lubrication or gas ballast. Its core architecture leverages corrosion-resistant wetted materials including anodized aluminum oxide (Al₂O₃), chemically inert PTFE, high-performance FFKM elastomers, polyphenylsulfone (PPS), and nitrile rubber (NBR), ensuring long-term compatibility with aggressive solvents, acids, and organic vapors commonly encountered in rotary evaporation, filtration, distillation, and vacuum drying applications. The pump operates silently at ≤54 dB(A) under typical low-vacuum conditions, minimizing acoustic disturbance in shared lab environments.

Key Features

• Compact footprint (115 × 292 × 280 mm) enables installation behind benchtop instruments—including rotary evaporators and vacuum ovens—optimizing fume hood space without compromising accessibility.
• Variable-speed control (285–1100 rpm) allows real-time adjustment of vacuum level and flow rate to match process requirements, improving solvent recovery efficiency and reducing bumping during sensitive evaporation steps.
• Integrated USB-C interface and analog input support bidirectional communication with compatible controllers (e.g., IKA VC 10 lite), enabling synchronized operation with vacuum regulators and recirculating chillers for fully automated pressure ramping and endpoint detection.
• Automatic self-cleaning cycle—triggered via controller integration—evacuates residual solvent vapors from internal chambers and diaphragm housings, significantly extending service intervals and maintaining consistent pumping performance over time.
• Robust cast-aluminum housing with thermoplastic polymer coating provides mechanical stability, thermal dissipation, and resistance to incidental chemical splashes; IP20-rated enclosure ensures safe operation in standard laboratory ambient conditions (5–40 °C, ≤80% RH).

Sample Compatibility & Compliance

The VACSTAR lite is suitable for use with aqueous, polar, and moderately aggressive organic media—including acetone, ethanol, ethyl acetate, dichloromethane, and dilute mineral acids—provided vapor concentrations remain within the pump’s specified inlet pressure range (10–1030 mbar). Its material construction complies with EU Directive 2011/65/EU (RoHS) and meets essential safety requirements per EN 61010-1:2010 for electrical equipment used in laboratory settings. While not certified for explosive atmospheres (ATEX), its oil-free design eliminates ignition risk associated with hydrocarbon-lubricated systems. For GxP-regulated environments, the pump supports audit-ready workflows when paired with IKA’s VC 10 lite controller, which logs operational parameters—including speed, runtime, and vacuum setpoints—with timestamped records compliant with FDA 21 CFR Part 11 principles (when deployed on validated IT infrastructure).

Software & Data Management

The VACSTAR lite itself does not include onboard software but functions as a programmable peripheral within IKA’s Labworldsoft ecosystem. When connected to a VC 10 lite vacuum controller or third-party systems via USB-C or 0–10 V analog signal, it accepts setpoint commands and reports real-time status (speed, temperature, fault codes). All communication adheres to IKA’s open ASCII-based protocol, facilitating integration into LIMS or ELN platforms through standard serial-to-USB or OPC UA gateways. Data logging—performed externally by the controller—includes vacuum trajectory, pump runtime, cleaning cycles, and error events, supporting traceability for ISO/IEC 17025 or GLP audits.

Applications

• Routine solvent removal in rotary evaporation (RotaVap) under controlled vacuum gradients
• Vacuum-assisted gravity and pressure filtration of biological or chemical suspensions
• Short-path and fractional distillation requiring stable sub-atmospheric pressure
• Drying of heat-sensitive samples in vacuum desiccators or ovens
• Supporting vacuum manifold systems for parallel sample concentration or lyophilization pre-treatment
• Gas scavenging and inert atmosphere purging in Schlenk-line adjacent setups

FAQ

Is the VACSTAR lite suitable for continuous 24/7 operation?
Yes—its brushless DC motor, thermally optimized housing, and sealed diaphragm assembly are rated for uninterrupted duty cycles under nominal load conditions (≤70% max speed, ambient ≤30 °C).
Can it handle water vapor or condensable vapors without damage?
It tolerates intermittent exposure to water vapor when used with cold traps or condensers upstream; however, sustained pumping of saturated steam or high-humidity gases may accelerate diaphragm fatigue and is not recommended.
Does it require periodic oil changes or lubrication?
No—it is a fully oil-free system; no maintenance beyond occasional external cleaning and inspection of inlet/outlet fittings is required.
What vacuum controllers are compatible?
Officially supported controllers include the IKA VC 10 lite and RV 10 digital; analog-compatible third-party controllers with 0–10 V output and TTL-level USB-C handshake capability may also be integrated.
Is firmware upgradable in the field?
Firmware updates are delivered exclusively through IKA-certified service centers and require proprietary diagnostic hardware; end users cannot perform self-upgrades.
