Overview
The WIGGENS BioVac 240 Portable Liquid Aspiration System is an engineered solution for safe, reliable, and aseptic liquid removal in bioscience laboratories. Designed around a maintenance-free, oil-free diaphragm vacuum pump, the system eliminates the risk of oil contamination, reduces long-term operational costs, and ensures consistent vacuum performance across repeated use cycles. Its core function—bio-suction—is optimized for post-culture workflows, including spent media removal from cell culture flasks, T-plates, and bioreactors, as well as general laboratory waste fluid aspiration under laminar flow hoods or biosafety cabinets. The BioVac 240 operates on a closed-loop aspiration principle: vacuum is generated by the diaphragm pump, transmitted through sterilizable tubing and a 0.2 µm hydrophobic PTFE disc filter, and applied to the sample via interchangeable suction tips. This architecture maintains sterility integrity while preventing cross-contamination between samples and protecting the pump from liquid ingress.
Key Features
- Maintenance-free oil-free diaphragm vacuum pump with thermal overload protection and extended service life
- Dual-stage overflow protection: integrated float valve in the 3000 mL autoclavable polycarbonate waste bottle + upstream 0.2 µm PTFE membrane filter
- Foot-operated switch for hands-free control—critical during aseptic procedures requiring glove integrity and workflow continuity
- Compact, portable chassis (54 × 26 × 35 cm; 12 kg) with reinforced carrying handle and non-slip rubber feet for stable placement on benchtops or inside biosafety cabinets
- Full autoclave compatibility: waste bottle, filter housing, and all wetted PTFE and silicone components withstand standard steam sterilization (121 °C, 20 min, 1 bar)
- Low-noise operation (<52 dB(A) at 1 m), enabling use in shared lab environments without acoustic disturbance
Sample Compatibility & Compliance
The BioVac 240 is validated for aspiration of aqueous biological fluids—including DMEM, RPMI-1640, PBS, trypsin-EDTA solutions, and clarified cell lysates—without degradation of vacuum stability or filter clogging. Its 0.2 µm PTFE filter meets ISO 8573-1 Class 2 particulate purity requirements for sterile gas pathways and provides effective barrier protection against aerosolized microorganisms per EN 14683:2019 Annex A. The system supports GLP-compliant documentation when paired with electronic logbooks, and its design aligns with core principles of USP for apparatus used in sterile processing. All materials in contact with liquids comply with USP Class VI biocompatibility testing, and the polycarbonate waste bottle is certified free of leachable bisphenol-A (BPA-free).
Software & Data Management
The BioVac 240 is a standalone hardware system with no embedded firmware or digital interface. It requires no software installation, driver configuration, or network connectivity—ensuring operational simplicity, cybersecurity resilience, and full compatibility with ISO/IEC 17025-accredited laboratory IT policies. Vacuum level and flow rate are fixed by mechanical design and do not require calibration traceability; however, users may validate performance using calibrated pressure gauges (e.g., ASTM E2877-22 compliant) and volumetric flow meters prior to critical applications. Audit trails for sterilization cycles must be maintained manually per institutional SOPs, consistent with FDA 21 CFR Part 11 expectations for equipment used in regulated bioprocessing environments.
Applications
- Spent medium aspiration from adherent and suspension cell cultures during passaging and harvesting
- Routine removal of supernatants following centrifugation or sedimentation steps
- Debris and wash buffer aspiration in histology and immunostaining workflows
- Safe aspiration of low-viscosity reagents and buffers within laminar flow hoods and Class II biosafety cabinets
- Supporting GMP-aligned cleanroom operations where oil-free vacuum sources are mandated per EU GMP Annex 1 (2022)
FAQ
Is the BioVac 240 suitable for aspiration of viscous or protein-rich solutions?
The system is optimized for low-to-medium viscosity aqueous fluids (≤10 mPa·s). For highly viscous or particulate-laden samples, pre-filtration through a 5 µm mesh or use of larger-diameter tubing is recommended to maintain flow stability.
Can the 0.2 µm PTFE filter be reused after autoclaving?
Yes—the hydrophobic PTFE disc filter is rated for ≥20 autoclave cycles at 121 °C without loss of pore integrity or bubble point performance, provided it is thoroughly dried before reuse.
Does the BioVac 240 meet IEC 61000-6-3 electromagnetic compatibility standards?
Yes—the diaphragm pump and control circuitry conform to IEC 61000-6-3 (2019) for industrial environment radiated emissions and IEC 61000-6-2 for electrostatic discharge immunity.
What is the expected service life of the vacuum pump under continuous daily use?
Rated for >15,000 hours of operation with no scheduled maintenance, assuming ambient temperatures ≤35 °C and relative humidity <80% non-condensing.
Are replacement parts and accessories available through global distribution channels?
Yes—WIGGENS-certified spare parts (including PTFE filters, foot switches, and aspiration kits) carry harmonized EU CE marking and are distributed via ISO 13485-certified partners in North America, EMEA, and APAC regions.
