Overview
The WIGGENS BioVac Portable Liquid Aspiration System is an engineered solution for sterile, controlled liquid removal in bioscience and cell culture laboratories. Designed around a maintenance-free, oil-free diaphragm vacuum pump, the system operates on the principle of negative pressure generation to aspirate liquids—primarily culture supernatants, spent media, and biological waste—without introducing hydrocarbon contamination or requiring routine lubrication. Its compact, benchtop-portable architecture integrates seamlessly into laminar flow hoods and biosafety cabinets, supporting aseptic workflows where cross-contamination risk must be minimized. The BioVac is not a general-purpose vacuum source but a purpose-built aspiration platform optimized for intermittent, low-to-moderate volume liquid handling under Class II biosafety conditions.
Key Features
- Oil-Free Diaphragm Pump: Eliminates need for lubricating oil, ensuring zero risk of oil vapor backstreaming into the aspiration path—critical for maintaining sterility and preventing sample contamination in cell culture environments.
- Dual Overflow Protection: Incorporates two independent safeguards: (1) a float-activated shut-off valve inside the polycarbonate waste bottle, and (2) a hydrophobic 0.2 µm PTFE disc filter placed between the bottle and pump head—preventing liquid ingress into the pump mechanism even during accidental overfilling.
- Autoclavable Components: Both the transparent polycarbonate waste bottle and the PTFE filter disc are rated for repeated sterilization at 121 °C, 15 psi, for 20 minutes per cycle—fully compliant with ISO 17665-1 and standard GLP laboratory sterilization protocols.
- Ergonomic & Workflow-Optimized Interface: Includes a multi-position suction wand with adjustable tip geometry, reinforced silicone tubing rated for repeated autoclaving, and a foot-operated momentary switch enabling hands-free activation—reducing operator fatigue and minimizing glove contact with non-sterile surfaces.
- Acoustic Performance: Operates at ≤52 dB(A) at 1 m distance—engineered for quiet integration into shared lab spaces without compromising auditory comfort during extended use.
Sample Compatibility & Compliance
The BioVac is validated for aspiration of aqueous-based biological fluids including DMEM/F12, PBS, trypsin-EDTA solutions, and conditioned cell culture media. It is not intended for solvents, highly viscous suspensions (>500 cP), or corrosive acids/bases beyond pH 4–10. All wetted materials—including tubing, bottle, and filter housing—are USP Class VI-certified and extractables-tested per ISO 10993-12. The system meets IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) standards. While not certified as medical device (MDR/IVDR), its design aligns with ISO 13485-aligned manufacturing practices and supports audit readiness for FDA 21 CFR Part 11–governed environments when paired with traceable usage logs.
Software & Data Management
The BioVac is a standalone hardware system with no embedded firmware or digital interface. Operation is purely electro-mechanical—ensuring deterministic response, zero software obsolescence, and full compatibility with regulated environments where validation of electronic records is required. For labs implementing electronic lab notebooks (ELN) or LIMS, manual entry of aspiration events—including date/time, operator ID, bottle batch number, and cycle count—is recommended. The system’s mechanical simplicity eliminates cybersecurity concerns associated with connected devices and supports long-term reproducibility across instrument lifecycles without dependency on vendor-specific drivers or cloud services.
Applications
- Removal of spent culture media from adherent and suspension cell cultures prior to passaging or harvesting
- Aspiration of supernatant during centrifugation workflows in biosafety cabinets
- Drainage of wash buffers during immunostaining or ELISA plate processing
- Controlled removal of excess reagent from tissue sections in histology preparation
- Low-risk aspiration of clarified lysates post-filtration in protein purification setups
FAQ
Can the BioVac be used inside a CO₂ incubator?
No—the unit is designed for ambient laboratory use only; neither the pump nor electronics are rated for elevated temperature/humidity environments.
Is the 0.2 µm PTFE filter certified for bacterial retention?
Yes—validated per ASTM F838-22 using Brevundimonas diminuta (ATCC 19146) challenge testing, demonstrating ≥log 7 reduction at rated flow.
What is the expected service life of the diaphragm pump under typical lab usage?
Rated for >10,000 hours MTBF when operated within specified vacuum and duty-cycle limits (≤30% continuous duty).
Does the system comply with EU RoHS and REACH directives?
Yes—all components conform to Directive 2011/65/EU (RoHS2) and Regulation (EC) No 1907/2006 (REACH), with full material declarations available upon request.
Can third-party waste bottles be used?
Not recommended—only WIGGENS-supplied polycarbonate bottles ensure dimensional compatibility with the float switch and secure sealing against vacuum leakage.
