Overview
The IKA VACSTAR control is a high-precision, oil-free diaphragm vacuum pump engineered for reproducible, chemically resistant operation in demanding laboratory environments. Based on a four-stage diaphragm architecture with PTFE-coated membranes and ceramic Al₂O₃ pressure sensing technology, it delivers stable vacuum generation across a broad operational range (1–1030 mbar). Its core measurement principle relies on positive displacement via elastomeric diaphragm oscillation—eliminating oil contamination risks while ensuring compatibility with aggressive solvents including acetone, chloroform, ethyl acetate, and acetonitrile. Designed for integration into vacuum-controlled workflows such as rotary evaporation, filtration, freeze drying, and solvent removal, the VACSTAR control operates with minimal maintenance due to its corrosion-resistant wetted path and sealed motor assembly. Its modular design supports both standalone use and networked deployment within GLP/GMP-compliant laboratories.
Key Features
- Four-stage diaphragm pumping system for enhanced vacuum stability and reduced pulsation
- Integrated ceramic Al₂O₃ absolute pressure sensor with ±1 mbar accuracy and full-scale range from 1 to 1030 mbar
- TFT graphical display with real-time pressure readout in selectable units (mbar, hPa, Torr, mmHg)
- Multi-mode control: manual, automatic, % output, and programmable sequence modes via front-panel rotary knob or remote interface
- Dual-port condensation management: inlet cold trap (VSE 1 compatible) and integrated outlet condensate coil for volatile solvent recovery
- RS232 and USB connectivity for instrument control, data logging, and compliance with FDA 21 CFR Part 11 audit trail requirements
- Low-power standby mode (1.5 W) and energy-efficient 140 W motor operating at 100–240 V AC, 50/60 Hz
- IP20-rated cast aluminum housing with thermoplastic polymer coating for mechanical robustness and ESD-safe handling
Sample Compatibility & Compliance
The VACSTAR control is validated for continuous operation with organic solvents, aqueous solutions, and mildly acidic or basic vapors. All fluid-contact materials—including PTFE diaphragms, FPM valves, PPS housings, and Al₂O₃ sensor elements—meet ISO 10993 biocompatibility guidelines and are resistant to hydrolysis and oxidative degradation. It complies with DIN EN 60529 (IP20), CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), and RoHS 2011/65/EU. When paired with IKA’s VC 10 vacuum controller or third-party systems supporting Modbus RTU over RS232, it supports automated method execution aligned with ASTM E2656 (Standard Practice for Vacuum Distillation) and USP (Vacuum Measurement).
Software & Data Management
The pump supports bidirectional communication via ASCII-based serial protocol over RS232 or virtual COM port over USB. Raw pressure data, runtime logs, and mode transitions can be streamed in real time to LIMS or ELN platforms. Firmware includes built-in timestamped event logging (start/stop, mode changes, error codes) with configurable retention intervals—enabling full traceability per GLP Annex 11 and GMP Annex 11 requirements. Optional IKA Labworld software provides graphical trend analysis, alarm threshold configuration, and export to CSV/PDF for regulatory submissions.
Applications
- Routine and preparative rotary evaporation of heat-sensitive compounds under controlled vacuum gradients
- Vacuum-assisted gravity and pressure filtration of fine particulates in pharmaceutical QC labs
- Concentration of biological extracts without thermal degradation
- Boiling point determination using integrated vapor pressure correlation algorithms
- Automated multi-step solvent removal protocols in parallel synthesis workstations
- Environmental sample preparation requiring VOC containment and recovery compliance (EPA Method 502.2)
FAQ
Is the VACSTAR control suitable for corrosive acid vapors such as HCl or HF?
No. While PTFE and Al₂O₃ offer broad chemical resistance, hydrofluoric acid and concentrated hydrochloric acid at elevated temperatures may compromise valve seals and sensor integrity. Use only with solvents listed in IKA’s Material Compatibility Guide.
Can the pump operate continuously for 24/7 applications?
Yes—when ambient temperature remains within 5–40 °C and relative humidity ≤80 % RH, with adequate ventilation. Continuous duty cycle is supported by thermal overload protection and brushless motor design.
Does it meet FDA 21 CFR Part 11 requirements for electronic records?
Yes, when used with validated software (e.g., IKA Labworld v3.2+) that enforces user authentication, audit trails, and electronic signatures.
What vacuum accessories are required for optimal solvent recovery?
We recommend pairing with the optional VSE 1 secondary cold trap and an inline particulate filter (IKA part no. 302000) to maximize condensate capture and extend diaphragm service life.
How is calibration performed and how often is it needed?
The ceramic pressure sensor is factory-calibrated and requires no routine recalibration. Verification against a NIST-traceable reference manometer is recommended annually or after exposure to >1000 mbar overpressure events.
