ROCKER BioVac 330B Vacuum Filtration System

Overview

The ROCKER BioVac 330B Vacuum Filtration System is an integrated, laboratory-grade solution engineered for high-throughput microbial enumeration and sterile liquid clarification in regulated life science environments. Based on the principle of negative-pressure-driven membrane filtration, the system enables rapid, consistent separation of microorganisms from aqueous samples—including water, beverages, pharmaceutical buffers, and culture media—by drawing fluid through a defined-pore-size membrane under controlled vacuum. Its architecture centers on a robust, fully autoclavable 3-channel filtration manifold constructed entirely from medical-grade SUS316 stainless steel, ensuring long-term resistance to corrosive reagents, repeated thermal sterilization cycles, and mechanical wear. Coupled with an oil-free Rocker 400 vacuum pump delivering stable −85 kPa suction and 25 L/min free-air flow, the BioVac 330B eliminates hydrocarbon contamination risks while maintaining low noise (<50 dB(A)) and minimal heat generation—critical for extended operation in biosafety cabinets or laminar flow hoods.

Key Features

• Triple-channel SUS316 stainless steel filtration manifold with patented M381450 rotary-lock coupling mechanism—enabling tool-free, leak-tight assembly and disassembly in under 5 seconds per unit.
• Full-system compatibility with standard 47 mm diameter membranes (e.g., Pall GN-6 mixed cellulose ester, 0.45 µm pore size), validated per ASTM D1293 and ISO 9308-1 for total coliform and E. coli detection.
• Integrated Dragon 100 electronic ignition Bunsen burner for rapid, repeatable flame sterilization of filtration funnels and forceps—eliminating manual gas valve adjustments and pilot-light hazards.
• 3000 mL polycarbonate waste bottle with integrated anti-splash baffle and dual-port venting; rated for continuous use at −85 kPa with chemical resistance to ethanol, isopropanol, dilute acids/bases, and common disinfectants.
• Pre-assembled high-pressure silicone tubing (2 × 1 m, 6 mm ID) with reinforced barb fittings—designed for fatigue resistance over ≥5,000 vacuum cycles without cracking or delamination.
• Two-year comprehensive parts warranty covering pump diaphragm, manifold gaskets, electronic igniter PCB, and all factory-installed seals—aligned with ISO 13485 service documentation requirements.

Sample Compatibility & Compliance

The BioVac 330B supports filtration of volumes ranging from 10 mL to 2,000 mL per channel, accommodating turbid suspensions, viscous biological fluids (e.g., milk, serum, fermentation broths), and low-particulate process streams. All wetted components comply with USP Class VI biocompatibility standards and are non-pyrogenic after autoclaving at 121 °C for 20 minutes. The system meets critical regulatory expectations for microbiological testing workflows: it facilitates adherence to FDA Bacteriological Analytical Manual (BAM) Chapter 4 (Membrane Filtration Method), APHA Standard Methods 9222B, and EU Pharmacopoeia 2.6.28. Its traceable component lot numbers, serialized pump units, and documented calibration intervals support audit readiness under GLP and GMP frameworks—including 21 CFR Part 11 data integrity considerations when paired with ROCKER’s optional LogView Pro software.

Software & Data Management

While the BioVac 330B operates as a standalone hardware platform, its modular design allows seamless integration into digital lab infrastructure. When used with the optional LogView Pro PC application (v3.2+), users can log vacuum pressure trends, pump runtime hours, sterilization event timestamps, and filter batch identifiers—generating PDF reports compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate). All electronic records include operator ID, date/time stamps, and cryptographic hash verification to satisfy FDA 21 CFR Part 11 electronic signature requirements. Firmware updates are delivered via secure HTTPS with SHA-256 signature validation.

Applications

• Quantitative microbial analysis of potable water, wastewater, and environmental samples per EPA Method 1603 and ISO 9308-1.
• Sterility testing of injectables, ophthalmic solutions, and cell culture media in compliance with USP and Ph. Eur. 5.1.1.
• Clarification of crude lysates, antibody harvests, and viral vector supernatants prior to downstream chromatography or ultracentrifugation.
• Routine QC filtration in biomanufacturing cleanrooms where hydrocarbon-free vacuum sources are mandated by ISO 14644-1 Class 5/7 specifications.
• Educational microbiology labs requiring durable, flame-sterilizable equipment aligned with ABET-accredited curriculum standards.

FAQ

Is the BioVac 330B suitable for filtering organic solvents such as acetone or chloroform?
No. The polycarbonate waste bottle and silicone tubing are incompatible with halogenated and ketonic solvents. For such applications, ROCKER recommends the BioVac 330S variant with PTFE-lined components.
Can the SUS316 filtration manifold be sterilized using ethylene oxide (EtO)?
Yes—full EtO sterilization (55 °C, 60% RH, 600 mg/L, 3 hours) is validated per ISO 11135. Residual gas desorption protocols must follow manufacturer-recommended aeration times.
What maintenance is required for the Rocker 400 vacuum pump?
The diaphragm pump requires no oil changes. Annual inspection of inlet filters and replacement of the diaphragm every 12,000 operating hours (or ~24 months at 8 hrs/day) is recommended per ISO 5388 maintenance schedules.
Does the system include membrane holder certification for pharmacopeial methods?
Yes—each BioVac 331 manifold carries a Certificate of Conformance stating compliance with USP particulate matter testing requirements for filter holder geometry and flow path integrity.
How is user training provided for GLP-compliant operation?
ROCKER offers on-site or virtual SOP development workshops, including blank run documentation templates, calibration checklists, and deviation reporting forms aligned with Annex 11 and ICH-GCP guidelines.
