IKA VACSTAR 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. Utilizing a four-stage diaphragm chamber architecture, it delivers consistent vacuum generation without lubricating oils—eliminating risk of sample contamination and enabling safe handling of chemically aggressive vapors. Its core operating principle relies on synchronized reciprocating motion of chemically resistant PTFE-coated diaphragms, driven by a brushless motor with integrated speed feedback. This design ensures stable flow rates across variable backpressure conditions and supports applications requiring clean, dry, and hydrocarbon-free vacuum down to 2 mbar. The pump is particularly suited for rotary evaporation, vacuum filtration, freeze drying, degassing, and solvent recovery workflows where chemical compatibility, low maintenance, and regulatory compliance are critical.

Key Features

• Four-stage diaphragm system for enhanced suction efficiency and improved ultimate vacuum performance (2 mbar)
• Digital LED display with real-time monitoring of rotational speed (rpm), enabling precise process control and repeatability
• Adjustable speed range from 285 to 1200 rpm via intuitive rotary encoder—optimizes vacuum level and flow rate per application demand
• Chemically inert wetted materials including PTFE, FFKM (FFPM), Al₂O₃, PPS, and NBR—ensuring long-term resistance to acids, bases, solvents, and halogenated compounds
• Integrated RS232 and USB interfaces for seamless integration into automated lab systems and remote parameter logging
• Multi-mode operation: manual, auto, %-based vacuum setpoint control, and programmable multi-step sequences for unattended operation
• Low-noise design (54 dB(A) at low vacuum) and compact footprint (150 × 375 × 370 mm) suitable for benchtop deployment in shared or space-constrained laboratories
• Energy-efficient operation with only 3 W standby power consumption and full-load input of 130 W

Sample Compatibility & Compliance

The VACSTAR digital is designed for use with a broad spectrum of volatile and corrosive media common in synthetic chemistry, pharmaceutical development, and analytical sample preparation. Its PTFE diaphragms and FFKM valve seals provide exceptional resistance to acetone, dichloromethane, methanol, THF, acetonitrile, and concentrated mineral acids—making it compatible with most standard organic and aqueous solvent systems. The pump meets DIN EN 60529 (IP20) for electrical safety and indoor use, and conforms to IEC 61000-6-3 (EMC emission standards). When paired with optional accessories such as the VC10 vacuum controller or VSE1 secondary condenser, the system supports GLP-compliant documentation workflows and aligns with USP guidance for analytical instrument qualification. Its oil-free operation satisfies ISO 8573-1 Class 0 requirements for compressed air purity—extending relevance to controlled environments where hydrocarbon contamination must be avoided.

Software & Data Management

The built-in RS232 and USB ports support bidirectional communication with third-party software platforms (e.g., LabVIEW, MATLAB, or custom LIMS integrations) and IKA’s proprietary Labworldsoft suite. Users can log vacuum profiles, speed settings, runtime duration, and error events with timestamped records. Audit-trail functionality—including user ID tagging and change history—is available when configured with validated software modules compliant with FDA 21 CFR Part 11 requirements. Firmware updates are delivered via USB stick, ensuring long-term adaptability to evolving regulatory expectations and operational needs.

Applications

• Rotary evaporation under controlled vacuum for heat-sensitive compound isolation
• Vacuum-assisted filtration of aggressive filtrates in pharmaceutical QC labs
• Pre-concentration and solvent removal in environmental sample analysis (e.g., EPA Method 502.2)
• Freeze-drying cycle support in biopharmaceutical formulation development
• Inert atmosphere purging prior to Schlenk-line or glovebox transfer
• Gas-phase extraction and headspace analysis sample preparation
• Integration into automated synthesis platforms requiring programmable vacuum sequencing

FAQ

What vacuum level can the VACSTAR digital achieve without gas ballast?
It reaches an ultimate pressure of 2 mbar under standard ambient conditions (23 °C, 50 % RH) with no gas ballast activated.
Is the pump suitable for continuous duty operation?
Yes—it is rated for continuous operation within the specified ambient temperature (5–40 °C) and humidity limits (≤80 % RH, non-condensing).
Can the pump be controlled remotely via computer?
Yes—via RS232 or USB using ASCII command protocol; full parameter readout and setpoint adjustment are supported.
Which accessories are required for automated vacuum regulation?
The VC10 vacuum controller (sold separately) connects directly using the included analog cable; no additional interface hardware is needed.
Does the pump require routine maintenance beyond diaphragm replacement?
No scheduled lubrication or oil changes are necessary; periodic inspection of inlet filters and diaphragm integrity is recommended per IKA’s maintenance schedule (typically every 6–12 months depending on usage intensity).
