ROCKER BioVac 321 Triple-Position Aluminum Vacuum Filtration Manifold

Overview

The ROCKER BioVac 321 is a precision-engineered triple-position vacuum filtration manifold designed for reproducible, operator-controlled liquid separation in life science and analytical laboratories. Built on the principle of controlled negative pressure-driven membrane filtration, the BioVac 321 enables simultaneous or sequential processing of up to three samples using standard filter assemblies secured via #8 rubber stoppers. Its modular architecture supports both qualitative and quantitative filtration protocols—including microbial enumeration (e.g., membrane filtration per ISO 7218 or ASTM D5465), particulate removal from reagents, clarification of cell lysates, and pre-filtration prior to HPLC or mass spectrometry analysis. Unlike plastic manifolds subject to creep deformation under vacuum or thermal stress, the BioVac 321’s anodized aluminum body ensures dimensional stability across repeated autoclaving cycles and maintains consistent sealing integrity at operating pressures up to –95 kPa.

Key Features

• Triple independent vacuum control: Each of the three filtration ports is equipped with a dedicated plated copper valve, enabling selective activation without cross-port pressure interference—critical for differential sample processing or staggered timing in high-throughput workflows.
• Autoclavable construction: Fully compatible with standard steam sterilization (121°C, 20 minutes, 100 kPa gauge pressure), supporting aseptic filtration in microbiology, pharmaceutical QC, and cell therapy labs operating under ISO 13485 or FDA 21 CFR Part 11–aligned environments.
• Universal stopper interface: Standard #8 rubber stopper compatibility ensures seamless integration with commercially available filtration funnels (e.g., Nalgene™, Corning®, Whatman™) ranging from 25 mm to 142 mm diameter, eliminating proprietary adapter dependencies.
• Corrosion-resistant materials: Anodized aluminum body provides Class II anodization (per MIL-A-8625 Type II), while electroplated copper valves and fittings resist oxidation during exposure to alcohols, dilute acids, and buffered saline solutions commonly used in life science applications.
• Ergonomic handling: Lightweight design (approx. 1.8 kg) with integrated anodized aluminum handle facilitates safe transport between laminar flow hoods, biosafety cabinets, and cold rooms without compromising structural rigidity.

Sample Compatibility & Compliance

The BioVac 321 supports filtration of aqueous buffers, ethanol/water mixtures, phosphate-buffered saline (PBS), nutrient broths, and low-viscosity organic solvents (e.g., ethyl acetate, acetone) when paired with chemically resistant membranes (e.g., PVDF, PTFE, or mixed cellulose ester). It is routinely deployed in compliance-critical settings—including USP sterility testing, EPA Method 1603 for E. coli detection, and ISO 6222 for total coliform enumeration. The device itself does not require calibration but is validated as part of end-user system qualification; its passive mechanical design eliminates electronic components that would necessitate 21 CFR Part 11 audit trails. Documentation packages include material certifications (RoHS, REACH) and autoclave cycle validation guidance for IQ/OQ execution.

Software & Data Management

As a purely mechanical vacuum manifold, the BioVac 321 operates without embedded electronics, firmware, or software dependencies. This analog architecture eliminates cybersecurity risks, firmware update overhead, and software validation burdens—making it ideal for regulated environments where ALCOA+ data integrity principles are enforced. Laboratory records generated using the BioVac 321 (e.g., filter lot numbers, operator IDs, time stamps, and colony counts) are maintained externally in LIMS or paper-based logbooks, fully traceable under GLP and GMP frameworks. Optional accessories—including vacuum gauges, inline moisture traps, and HEPA-filtered exhaust adapters—can be integrated without altering core functionality or compliance posture.

Applications

• Microbial quality control: Membrane filtration of water, beverages, and pharmaceutical raw materials per ISO 9308-1, USP , or Ph. Eur. 2.6.27.
• Bioprocess monitoring: Clarification of fermentation broths, harvest supernatants, and purification intermediates prior to chromatography or ultrafiltration.
• Environmental testing: Field-deployable filtration of surface water, wastewater effluents, and groundwater samples under EPA-approved methods.
• Academic research: Routine buffer exchange, precipitate recovery, and sterile filtration in molecular biology, immunology, and toxicology laboratories.
• Quality assurance labs: High-reproducibility filtration for reference standard preparation and particulate matter testing in injectables (USP ).

FAQ

Can the BioVac 321 be used with aggressive solvents such as chloroform or concentrated nitric acid?
No. While compatible with common laboratory solvents (e.g., ethanol, isopropanol, acetone), the anodized aluminum body and plated copper components are not chemically resistant to strong oxidizers or halogenated hydrocarbons. Consult the ROCKER Chemical Compatibility Guide before use.
Is the #8 stopper interface standardized across all major funnel manufacturers?
Yes. The #8 designation conforms to ANSI/ASTM D3951-22 dimensional specifications and is adopted by Nalgene, Corning, Pall, and Sartorius for 47 mm and 90 mm funnels.
Does the 2-year warranty cover labor or only replacement parts?
The warranty covers free replacement of defective parts only. On-site service or labor charges are not included but may be arranged separately through authorized ROCKER service partners.
Can I retrofit the BioVac 321 with a digital vacuum controller or pressure sensor?
Not directly—the manifold lacks threaded ports or electrical interfaces for OEM integration. However, third-party vacuum regulators or analog pressure gauges can be installed upstream in the vacuum line without affecting manifold performance or warranty terms.
What is the maximum recommended vacuum level for continuous operation?
For optimal seal longevity and valve actuation consistency, sustained operation should remain below –95 kPa (≈ 200 mbar absolute). Intermittent exposure to deeper vacuums (e.g., –98 kPa) is permissible but not advised for >10-minute durations.
