IKA VACSTAR control Controlled Vacuum Pump

Overview

The IKA VACSTAR control is a precision-engineered, four-stage diaphragm vacuum pump designed for reliable, oil-free operation in demanding laboratory environments. Utilizing a PTFE-coated multi-chamber diaphragm architecture, it delivers consistent vacuum performance across low-vacuum applications—including rotary evaporation, vacuum filtration, solvent removal, and degassing—without introducing hydrocarbon contamination or requiring lubrication maintenance. Its core operating principle relies on synchronous oscillation of chemically inert PTFE diaphragms driven by a brushless DC motor with integrated frequency-controlled speed regulation (285–1200 rpm), enabling precise dynamic response to process load changes. The pump achieves an ultimate vacuum of ≤ 2 mbar and maintains a stable pumping speed of 22 L/min (1.32 m³/h) under typical laboratory conditions (23 °C, 1013 mbar ambient pressure), making it suitable for applications governed by ASTM E1510 (standard practice for rotary evaporation), ISO 2719 (flash point determination), and USP (vacuum drying procedures).

Key Features

• Four-stage diaphragm design with PTFE-coated membranes and gas-path components—ensuring high chemical resistance to acids, bases, halogenated solvents, and organic vapors
• Integrated vacuum controller with intuitive front-panel interface and wireless remote control—enabling both manual setpoint adjustment and automated vacuum ramping profiles
• Infinitely variable speed drive (285–1200 rpm) with real-time LED digital display—supporting adaptive vacuum regulation based on solvent vapor pressure and system conductance
• Oil-free, dry-running operation—eliminating risk of oil backstreaming, reducing maintenance intervals, and complying with ISO 8573-1 Class 0 air purity requirements for vacuum systems
• USB interface compatible with IKA LabworldSoft software—facilitating remote monitoring, data logging, script-based automation, and audit-ready event tracking per FDA 21 CFR Part 11 requirements
• Low-noise operation at 54 dB(A) —optimized for shared lab spaces and continuous unattended use
• Modular port configuration with standardized 8 mm barbed inlet/outlet connections—compatible with common vacuum tubing, cold traps (e.g., VSE 1 secondary condenser), and vacuum manifolds

Sample Compatibility & Compliance

The VACSTAR control is validated for use with a broad spectrum of volatile and semi-volatile compounds, including acetone, methanol, ethyl acetate, dichloromethane, and tetrahydrofuran. Its PTFE-wetted path ensures compatibility with aggressive reagents encountered in pharmaceutical synthesis, environmental sample preparation, and polymer characterization workflows. The system meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. It conforms to RoHS 2011/65/EU restrictions on hazardous substances and supports GLP-compliant documentation when used with LabworldSoft’s electronic signature and audit trail functions.

Software & Data Management

LabworldSoft software provides full bidirectional communication via USB, enabling real-time vacuum setpoint programming, RPM modulation scheduling, runtime logging (timestamped vacuum values, motor speed, temperature warnings), and export of CSV-formatted datasets for LIMS integration. All parameter changes and operational events are recorded with user ID, timestamp, and reason code—fulfilling traceability requirements for ISO/IEC 17025-accredited laboratories and GMP-regulated QC environments. Firmware updates are delivered through the same interface, ensuring long-term compliance with evolving cybersecurity and data integrity standards.

Applications

• Controlled solvent removal in rotary evaporators (e.g., Buchi R-300, IKA RV 10) with automatic pressure compensation during boiling point shifts
• Vacuum-assisted gravity and pressure filtration of corrosive or heat-sensitive suspensions
• Deaeration of resin mixtures, adhesives, and composite precursors prior to casting or curing
• Pre-concentration of aqueous extracts in environmental analysis (EPA Method 525.3)
• Lyophilization pre-chamber evacuation and shelf cooling support in pilot-scale freeze dryers
• Gas purging and inert atmosphere establishment in Schlenk-line setups

FAQ

What vacuum range is the VACSTAR control rated for, and how is stability maintained across varying loads?
It operates in the rough vacuum range (1000–2 mbar) with closed-loop feedback from its integrated pressure sensor; the controller dynamically adjusts motor speed to maintain ±0.3 mbar setpoint accuracy under fluctuating system conductance.
Can the pump be integrated into automated workflows using third-party lab management systems?
Yes—via LabworldSoft’s OPC UA-compatible API or direct serial/USB command protocol (SCPI-style), enabling interoperability with LabVantage, Thermo Fisher SampleManager, and custom Python-based orchestration scripts.
Is the VACSTAR control suitable for continuous 24/7 operation in production QC labs?
Rated for continuous duty at ambient temperatures up to 40 °C; thermal overload protection and intelligent fan control ensure sustained reliability over extended cycles, validated per IEC 60034-1 service factor testing.
How does the optional VSE 1 secondary condenser interface with the pump?
It connects inline between the vacuum source and application apparatus using standard 8 mm vacuum tubing; its dual-stage Peltier-cooled trap achieves >95% solvent recovery efficiency for low-boiling-point organics, minimizing emissions and supporting ISO 14001 environmental compliance.
What documentation is provided for regulatory submissions?
Factory calibration certificate (traceable to NIST), Declaration of Conformity, electrical safety test report (EN 61010-1), and software validation package (IQ/OQ templates) are included with each unit.
