IKA VC 10 lite Vacuum Controller

Overview

The IKA VC 10 lite Vacuum Controller is an engineered solution for precise, repeatable, and safe vacuum regulation in academic, pharmaceutical, and industrial laboratory environments. Designed specifically for integration with IKA’s VACSTAR digital vacuum pump systems, the VC 10 lite operates on a closed-loop control architecture that dynamically adjusts pump speed via electronic frequency modulation—ensuring stable setpoint maintenance across variable load conditions (e.g., solvent boiling, filter cake formation, or desiccation kinetics). Unlike basic on/off vacuum switches, this controller employs a ceramic Al₂O₃ capacitive pressure sensor with absolute measurement capability (1–1100 mbar), delivering real-time feedback with ±1 mbar accuracy and 1 mbar resolution. Its core function is not merely pressure reduction but intelligent process management: it regulates vacuum intensity to match evolving system demands while minimizing solvent loss, thermal stress, and bumping risk—critical for sensitive applications such as rotary evaporation, vacuum filtration, lyophilization pre-treatment, and controlled drying of hygroscopic or thermolabile compounds.

Key Features

• Integrated ceramic Al₂O₃ pressure sensor with absolute measurement range from 1 to 1100 mbar and ±1 mbar uncertainty—certified for long-term stability under continuous operation.
• Dedicated VENT key with programmable inert gas purge logic (N₂ or Ar) to safely release vacuum and prevent sample oxidation or foaming during critical endpoint transitions.
• Self-cleaning algorithm automatically cycles the vent valve at predefined intervals to mitigate condensate accumulation and maintain sealing integrity—extending service life without manual intervention.
• 10-user-programmable vacuum protocols, each supporting up to 10 pressure/time segments; ideal for multi-stage processes like gradient drying or sequential solvent removal.
• Chiller control interface (24 V DC, 1 A output) enables synchronized cooling of condensers (e.g., VSE 1 secondary cold trap), improving solvent recovery efficiency by up to 40% compared to passive condensation.
• TFT display with four selectable pressure units (mbar, hPa, mmHg, Torr) and graphical real-time trend visualization—including pressure vs. time curves and protocol progress indicators.
• Built-in vacuum leakage test function performs automated integrity verification prior to process initiation—supporting GLP-compliant documentation requirements.

Sample Compatibility & Compliance

The VC 10 lite is compatible with all IKA VACSTAR digital vacuum pumps (e.g., VAC 200, VAC 300) and supports direct connection to glassware systems rated for vacuum use (DIN/ISO 2768-mK tolerances). Wetted materials—Al₂O₃ sensor diaphragm, PTFE-sealed valves, FPM O-rings, and PPS housing—ensure chemical resistance to common organic solvents (acetone, ethanol, ethyl acetate), mild acids, and bases within the specified 5–40 °C operating temperature range. The device complies with EU directives 2014/30/EU (EMC) and 2011/65/EU (RoHS), carries CE marking, and meets IP20 ingress protection per DIN EN 60529. While not inherently 21 CFR Part 11 compliant, its audit-ready features—including timestamped protocol execution logs, USB/RS232 data export, and chiller synchronization—facilitate integration into validated workflows under GMP/GLP frameworks when paired with labworldsoft® software.

Software & Data Management

The VC 10 lite communicates natively with IKA’s labworldsoft® platform via USB (USB-A to Micro-B, 2 m cable included) or RS232. This enables remote monitoring, parameter configuration, and full data logging—including pressure traces, program step timestamps, chiller status, and leakage test results. All exported data are stored in CSV format for traceability and third-party analysis (e.g., MATLAB, Python pandas). The controller stores up to 10 user-defined programs locally; no cloud dependency is required for standalone operation. Firmware updates are delivered via USB stick, ensuring offline maintainability in regulated environments where network isolation is mandated.

Applications

• Rotary evaporation: Precise vacuum ramping prevents bumping during low-boiling solvent removal; integrated VENT key enables safe flask venting before rotation stop.
• Vacuum-assisted filtration: Maintains optimal ΔP across membrane clogging cycles, improving throughput consistency in HPLC sample prep or cell culture harvest.
• Controlled drying of APIs and excipients: Multi-step programs replicate ICH Q5C stability study conditions (e.g., 25 °C/40% RH → 40 °C/75% RH) under defined vacuum profiles.
• Distillation under reduced pressure: Synchronized chiller control ensures condenser efficiency at sub-ambient temperatures, reducing solvent emissions and energy consumption.
• Material science sample preparation: Stable vacuum environment for degassing polymer precursors or preparing porous metal-organic frameworks (MOFs) without structural collapse.

FAQ

Can the VC 10 lite operate independently without a VACSTAR pump?
No—it is designed exclusively for use with IKA VACSTAR digital vacuum pumps and requires the proprietary control cable for motor speed modulation.
Is the pressure sensor calibrated traceable to NIST or DAkkS standards?
The ceramic Al₂O₃ sensor is factory-calibrated; optional DAkkS-accredited calibration certificates are available upon request (order code: CAL-VC10LITE-D).

Does the device support analog (0–10 V) or 4–20 mA external control inputs?
No—only digital communication via USB or RS232 is supported; no analog I/O interfaces are provided.

What is the maximum allowable ambient temperature for continuous operation?
40 °C, with relative humidity ≤80 % non-condensing, per EN 61010-1 safety specifications.

Can labworldsoft® generate PDF reports compliant with 21 CFR Part 11?
labworldsoft® v4.5+ supports electronic signatures, audit trails, and role-based access control—enabling Part 11 compliance when deployed on validated Windows Server infrastructure with appropriate IT governance.
