Overview
The HUXI HVAC-1LS Desktop Waste Liquid Collector is an engineered solution for low-volume, intermittent liquid waste aspiration in controlled laboratory environments. Designed around a compact, self-contained vacuum generation system, it operates on the principle of positive displacement diaphragm pumping—delivering stable, pulse-free suction across its specified vacuum range. Unlike centralized vacuum systems, the HVAC-1LS eliminates dependency on facility infrastructure, enabling deployment in biosafety cabinets, laminar flow hoods, cleanrooms, and mobile lab setups where space, portability, and electrical flexibility are critical constraints. Its modular architecture separates the vacuum pump unit from the collection vessel, allowing independent positioning of the 1 L bottle—ideal for ergonomic placement adjacent to workstations without compromising stability or accessibility.
Key Features
- Compact footprint (127 × 144 × 244 mm) and ultra-lightweight design (0.5 kg) optimize benchtop real estate—particularly suited for ISO Class 5–7 clean benches and confined analytical workspaces.
- Dual-power operation: supports either regulated DC 12 V / 1.0 A input or three standard AA alkaline batteries, ensuring uninterrupted functionality during power outages or field use.
- Precision vacuum control within a calibrated 600 mbar range enables reproducible aspiration across diverse liquid viscosities and surface tensions—critical for sensitive cell culture media removal or enzymatic assay cleanup.
- Integrated hydrophobic PTFE membrane filter (0.2 µm pore size) prevents aerosol ingress into the pump mechanism, extending service life and maintaining operational integrity under repeated sterilization cycles.
- One-touch activation with tactile feedback switch minimizes procedural steps—reducing operator fatigue and cross-contamination risk during high-frequency aspiration tasks.
- Acoustically optimized pump assembly achieves ≤53 dB(A) noise emission—compliant with WHO-recommended ambient noise limits for quiet laboratory zones.
Sample Compatibility & Compliance
The HVAC-1LS is compatible with aqueous buffers, saline solutions, diluted acids/bases (pH 2–12), ethanol/water mixtures, and cell culture supernatants. It is not rated for organic solvents (e.g., chloroform, acetone), halogenated compounds, or highly viscous fluids (>50 mPa·s at 25 °C). The standard 1 L polypropylene collection bottle is autoclavable at 121 °C / 15 psi for 20 minutes; optional 500 mL bottles are certified for repeated steam sterilization per ISO 17665-1. All wetted components comply with USP Class VI biocompatibility standards. Device construction adheres to IEC 61010-1:2010 safety requirements for laboratory electrical equipment.
Software & Data Management
As a manually operated, non-networked device, the HVAC-1LS does not incorporate embedded firmware, data logging, or digital interfaces. Its design prioritizes mechanical reliability and regulatory simplicity—making it suitable for GLP-compliant environments where audit trails are maintained via manual logbooks or LIMS-integrated workflow documentation. No software validation (e.g., FDA 21 CFR Part 11) is required, reducing qualification burden in QC/QA laboratories operating under ISO/IEC 17025 or GMP Annex 1 frameworks.
Applications
- Routine aspiration of spent media during mammalian cell passaging in biosafety cabinets.
- Removal of wash buffers following ELISA plate rinsing or Western blot membrane processing.
- Controlled decanting of supernatants in centrifugation workflows without disturbing pellet integrity.
- Low-risk vacuum filtration using optional filtration flasks for particulate removal from clarified lysates or chromatography fractions.
- Point-of-use waste capture in teaching labs, clinical pathology units, and rapid diagnostic testing stations where infrastructure scalability is limited.
FAQ
Can the HVAC-1LS be used with organic solvents such as ethanol or isopropanol?
Yes—dilute ethanol (<30% v/v) and isopropanol (<20% v/v) in aqueous solution are compatible. Pure or concentrated organic solvents will degrade the diaphragm seal and are strictly prohibited.
Is the hydrophobic filter replaceable, and what is its service life?
Yes—the 0.2 µm PTFE filter cartridge is user-replaceable (part no. HVAC-FIL-02). Under typical usage (≤200 mL aspirated per session, 5 sessions/day), expected lifetime exceeds 6 months before pressure drop exceeds 15% of initial value.
Does the device support continuous operation?
It is rated for duty cycles up to 15 minutes ON / 5 minutes OFF to prevent thermal overload of the DC motor. Extended continuous use may reduce pump longevity and void warranty coverage.
What sterilization methods are validated for the 500 mL collection bottle?
Autoclaving at 121 °C, 15 psi, 20 minutes is fully validated. Ethylene oxide (EtO) and gamma irradiation are not recommended due to potential polymer embrittlement.
How is calibration verified for vacuum output?
Vacuum accuracy is factory-verified using traceable digital manometers (NIST-traceable, ±1.5 mbar uncertainty). End users may perform functional verification using a calibrated handheld vacuum gauge connected to the aspiration port.
