ROCKER Biovac240 Cell Culture Vacuum Aspiration System

Overview

The ROCKER Biovac240 Cell Culture Vacuum Aspiration System is an oil-free, piston-driven vacuum pump engineered for reliable, contamination-free liquid aspiration in sensitive biological workflows. Designed specifically for cell culture laboratories, it operates on the principle of positive displacement to generate stable vacuum pressure without introducing hydrocarbon vapors or particulate residues—eliminating risks of sample cross-contamination or downstream interference in sterile environments. Its robust architecture delivers consistent performance at a nominal ultimate vacuum of 53 mbar and a maximum volumetric flow rate of 38 L/min, enabling rapid removal of spent media, trypsin solutions, supernatants, and other aqueous waste streams from culture vessels, flasks, and multiwell plates. The system’s fixed-voltage configuration (220 V / 50 Hz) ensures compatibility with standard laboratory power infrastructure across Asia-Pacific regions, while its compact footprint (530 × 240 × 350 mm) supports integration into biosafety cabinets, laminar flow hoods, and benchtop workflows without compromising ergonomics or accessibility.

Key Features

• Oil-free piston pump design eliminates lubricant degradation, oil mist emission, and routine maintenance requirements—ensuring long-term operational stability and compliance with ISO 14644-1 Class 5 cleanroom-compatible practices.
• Dual anti-spill protection: integrated float valve in the 3000 mL polycarbonate waste bottle + a hydrophobic 0.2 µm PTFE disc filter positioned between the bottle and pump head—preventing liquid ingress into the motor assembly under overfill or transient pressure conditions.
• Autoclavable components: all primary liquid-contact parts—including the waste reservoir, single-tip holders (150 mm), and optional stainless-steel tip adapters—are rated for repeated sterilization at 121°C for 20 minutes per ISO 17665-1, supporting GLP/GMP-aligned aseptic protocols.
• Integrated thermal overload protection automatically interrupts operation when internal temperature exceeds safe thresholds, preserving pump longevity and reducing unplanned downtime.
• Low-noise operation (<62 dB(A) at 1 m) minimizes acoustic disturbance in shared laboratory spaces and enhances user comfort during extended aspiration sessions.

Sample Compatibility & Compliance

The Biovac240 is validated for use with aqueous, low-viscosity biological fluids including DMEM/F12, PBS, trypsin-EDTA, serum-containing media, and conditioned supernatants. It is not intended for solvents, corrosive acids/bases, or viscous suspensions exceeding 100 mPa·s. All electrical and mechanical subsystems conform to EN 61000-6-3 (EMC Emission) and EN 61000-6-2 (EMC Immunity) standards. CE marking certifies compliance with the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not FDA 510(k)-cleared, its design aligns with USP recommendations for non-invasive liquid handling equipment used in pharmaceutical R&D settings.

Software & Data Management

The Biovac240 operates as a standalone analog device with no embedded firmware, touchscreen interface, or digital connectivity. This architecture ensures deterministic response time, zero firmware update dependencies, and immunity to cybersecurity vulnerabilities—making it suitable for regulated environments where validation simplicity and audit trail transparency are prioritized over feature-rich automation. All functional parameters (vacuum level, flow rate, duty cycle) remain manually observable via calibrated analog gauges and acoustic feedback cues. For labs requiring electronic recordkeeping, external vacuum loggers or PLC-integrated pressure transducers may be interfaced via standard 4–20 mA or 0–10 V analog outputs (available upon request with OEM integration kit).

Applications

• Routine aspiration of spent growth media during subculturing of adherent mammalian cell lines (e.g., HEK293, CHO, A549).
• Removal of supernatant post-centrifugation in suspension culture workflows.
• Drainage of wash buffers during immunostaining, ELISA plate processing, or flow cytometry sample preparation.
• Supporting sterile filtration setup priming and membrane rinsing in upstream bioprocessing labs.
• Assisting in aspiration-based tissue dissociation protocols where controlled, gentle vacuum is critical to preserve cell viability.

FAQ

Is the Biovac240 compatible with vacuum tubing larger than 5 mm inner diameter?
No—the system is optimized for 5 mm (3/16″) ID tubing; using larger diameters may compromise vacuum integrity and reduce achievable flow rates.
Can the PTFE filter be replaced in-house?
Yes—the 0.2 µm hydrophobic PTFE disc filter is a field-replaceable consumable (part number: 199100-77); replacement intervals depend on usage frequency and fluid composition.
Does the waste bottle include volume gradations?
Yes—the 3000 mL polycarbonate bottle features molded, autoclavable scale markings at 500 mL increments for visual volume monitoring.
What is the expected service life of the piston pump under continuous operation?
Rated for ≥10,000 hours of cumulative runtime with periodic inspection of sealing rings every 2,000 hours; typical lab usage (≤4 hrs/day) yields >5 years of reliable performance.
Are replacement tips and adapters available in non-sterile packaging for cost-sensitive applications?
Yes—ROCKER offers bulk-packaged POM and stainless-steel tip assemblies without pre-sterilization; end-users may validate their own sterilization cycles per internal SOPs.
