WIGGENS Biovac 350A Mobile Biomedical Liquid Aspiration System

Overview

The WIGGENS Biovac 350A Mobile Biomedical Liquid Aspiration System is an engineered solution for safe, efficient, and sterile liquid removal in bioscience laboratories. Designed around a maintenance-free oil-free piston vacuum pump, the system operates without lubricants—eliminating contamination risk, reducing long-term maintenance, and ensuring consistent performance across repeated sterilization cycles. Its core function is the controlled aspiration of culture supernatants, spent media, wash buffers, and other low-viscosity biological liquids during cell culture, tissue dissociation, and microbiological workflows. The system adheres to fundamental principles of negative-pressure fluid handling: vacuum generation via positive-displacement pumping, flow regulation through calibrated valve control, and physical barrier-based containment using hydrophobic membrane filtration. With an ultimate vacuum level of 60 mbar and a maximum volumetric flow rate of 80 L/min, it delivers sufficient suction force for rapid liquid transfer while maintaining compatibility with sensitive biological samples and laminar flow hood environments.

Key Features

• Oil-free piston vacuum pump: Ensures zero hydrocarbon contamination, complies with ISO 8573-1 Class 0 air purity requirements for critical biosafety applications.
• Dual independent aspiration channels: Enables simultaneous or sequential aspiration from two vessels; each channel features individual on/off control and integrated flow restriction.
• Real-time analog vacuum gauge: Provides immediate visual feedback of system pressure (mbar scale), supporting process repeatability and operator awareness during aspiration.
• Redundant overflow protection: Combines a float-activated shut-off switch inside the polycarbonate waste bottle and a 0.2 µm hydrophobic PTFE disc filter positioned between the bottle and pump head—preventing liquid ingress into the pump mechanism under overfill or sudden pressure drop conditions.
• Autoclavable components: Both 3000 mL PC waste bottles and the 0.2 µm PTFE filter discs are validated for steam sterilization at 121 °C for 20 minutes, meeting ISO 17665-1 requirements for moist heat sterilization of laboratory accessories.
• Mobile ergonomic design: Integrated locking casters (two fixed, two swivel with brakes) allow stable repositioning within biosafety cabinets, cleanrooms, or shared lab spaces without compromising vibration isolation or operational safety.
• Footswitch actuation: Hands-free operation supports aseptic technique by minimizing contact with controls during active procedures—critical for GLP-compliant cell passaging and primary tissue processing.

Sample Compatibility & Compliance

The Biovac 350A is compatible with aqueous, buffered, and mildly viscous biological liquids—including DMEM, PBS, trypsin-EDTA solutions, centrifugation supernatants, and clarified lysates—up to 10 cP viscosity at ambient temperature. It is not intended for organic solvents, corrosive acids/bases, or high-solids suspensions. All wetted parts (bottles, tubing connectors, filter housing) are constructed from USP Class VI-certified polycarbonate and PTFE, ensuring biocompatibility and extractables/leachables compliance per USP . The system meets IEC 61010-1:2010 safety standards for laboratory electrical equipment and carries CE marking under the EU Machinery Directive 2006/42/EC. While not a medical device, its design supports alignment with ISO 13485 quality management systems when deployed in regulated R&D environments.

Software & Data Management

The Biovac 350A is a standalone hardware system with no embedded microprocessor or digital connectivity. All operational parameters—including vacuum level and flow status—are conveyed via analog instrumentation and mechanical switching. This architecture eliminates firmware dependencies, cybersecurity vulnerabilities, and validation overhead associated with computerized systems. For labs operating under FDA 21 CFR Part 11 or EU Annex 11 requirements, the absence of electronic records simplifies audit readiness: aspiration events are documented manually in lab notebooks or electronic lab notebooks (ELNs) as part of standard operating procedures (SOPs). Calibration of the analog vacuum gauge is recommended annually per ISO/IEC 17025 guidelines, using traceable reference manometers.

Applications

• Removal of spent culture media during routine mammalian or insect cell passaging in biosafety cabinets.
• Aspiration of supernatants following centrifugation of blood, serum, or bacterial cultures.
• Drainage of wash buffers in immunostaining, ELISA plate preparation, and flow cytometry sample processing.
• Decontamination support: Safe collection of biohazardous liquids prior to chemical inactivation or autoclaving.
• High-throughput lab workflows requiring rapid, repeatable liquid clearance across multiple stations—enabled by mobility and dual-channel flexibility.

FAQ

Is the Biovac 350A suitable for aspiration of ethanol or isopropanol?
No. Organic solvents may degrade polycarbonate components and compromise the integrity of the PTFE filter. Only aqueous and buffer-based biological liquids are recommended.
Can the vacuum level be precisely regulated or setpoint-controlled?
The system provides manual flow control via adjustable valves per channel but does not feature programmable vacuum regulation. The analog gauge enables operator monitoring, not closed-loop control.
What is the expected service life of the piston pump under continuous daily use?
Based on manufacturer lifecycle testing, the oil-free piston mechanism maintains functional performance for ≥10,000 hours of cumulative operation when used within specified duty cycles and ambient temperature ranges (15–30 °C).
Are replacement PTFE filters supplied with defined shelf-life or sterility assurance?
Sterile-packaged filters are available with EO sterilization validation (ISO 11135) and a 36-month unopened shelf life. Non-sterile filters require user autoclaving prior to first use.
Does the system comply with noise emission limits for ISO Class 5 cleanrooms?
Yes. Operating noise is ≤52 dB(A) at 1 m distance—within the ISO 14644-1 permissible limit for background sound pressure in Grade A/B environments when installed with appropriate acoustic isolation.
