Guangzhou Jingying VF600 Six-Channel Direct-Discharge Vacuum Filtration System

Overview

The Guangzhou Jingying VF600 is a six-channel direct-discharge vacuum filtration system engineered for high-throughput, contamination-controlled sample preparation in analytical, environmental, food, and pharmaceutical laboratories. Unlike traditional Buchner funnel or multi-bottle vacuum setups, the VF600 employs a proprietary direct-discharge architecture—eliminating intermediate collection flasks and routing filtrate directly into a centralized waste reservoir. This design minimizes cross-contamination risk, reduces setup time, and enhances workflow continuity during batch processing of aqueous or low-viscosity organic extracts. Its operation is based on regulated negative pressure generation via an integrated diaphragm vacuum pump, delivering stable suction across all six independent channels. The system is optimized for standardized gravimetric, spectrophotometric, or chromatographic pre-analysis steps—including suspended solids quantification (e.g., ASTM D5907), total dissolved solids (TDS) isolation, particulate matter recovery from water samples (ISO 5667-12), and lipid extraction support per AOAC 991.36 or Soxhlet-compatible workflows.

Key Features

• Six independently controllable filter heads arranged in a compact single-row configuration—enabling parallel processing of up to six samples or selective activation of individual channels.
• Direct-discharge filtration path: filtrate flows continuously from disposable cups into a sealed waste container without intermediate glassware, reducing breakage risk and labor-intensive cleaning.
• Pre-assembled 500 mL disposable filtration cup kits featuring fast-flow hydrophilic or hydrophobic membranes (e.g., mixed cellulose ester, PTFE, or PVDF)—compatible with standard 47 mm or 50 mm disc membranes.
• Integrated LCD control panel with programmable timer (0–99 min), audible end-of-cycle alarm, and real-time status indicators for vacuum stability and channel activity.
• Acoustically damped diaphragm pump assembly achieving ≤60 dB(A) under operational load—suitable for shared lab environments requiring low ambient noise.
• Ergonomic cup base design incorporating a recessed membrane seating groove and protective lid for sterile handling; eliminates manual membrane placement errors and exposure to aerosols.
• Robust ABS housing with reinforced structural ribs and non-slip rubber feet—designed for long-term continuous operation (24/7 duty cycle rated).

Sample Compatibility & Compliance

The VF600 accommodates a broad range of liquid matrices including surface water, wastewater, digestates, cell culture supernatants, food homogenates, and solvent-based lipid extracts. All wetted components—including cup bodies, gaskets, and membrane supports—are chemically resistant to common laboratory solvents (e.g., acetone, chloroform, hexane, ethanol, and dilute acids/bases). The system supports method validation under GLP and GMP frameworks through consistent flow rate reproducibility (CV <3% across channels at fixed vacuum) and traceable parameter logging when paired with optional external data acquisition modules. While not intrinsically certified for hazardous area use, its electrical design complies with GB 4793.1–2019 (equivalent to IEC 61010-1) for safety in laboratory equipment.

Software & Data Management

The VF600 operates as a standalone instrument with embedded firmware controlling timing, vacuum regulation, and alarm logic. No proprietary software is required for basic operation. However, analog output (0–5 V) and digital relay signals are provided for integration into LIMS or SCADA systems—supporting automated start/stop triggers, vacuum monitoring, and cycle completion notifications. Audit trails can be maintained externally using timestamped loggers; for FDA 21 CFR Part 11 compliance, third-party electronic lab notebook (ELN) platforms may capture operator ID, run parameters, and completion timestamps via serial or USB interface adapters (sold separately).

Applications

• Environmental testing: Total suspended solids (TSS) determination per EPA Method 160.2 and ISO 11923.
• Food & agriculture: Crude fat extraction support (pre-filtration of ether extracts prior to gravimetric analysis), milk fat clarification, and juice particulate removal.
• Pharmaceutical QC: Clarification of dissolution media, filter integrity testing (pre-test rinsing), and sterile filtration validation prep.
• Research labs: High-volume cell pellet washing, nanoparticle recovery, and microplastic isolation from water samples (per CEN/TS 17594).
• Quality control: Routine filtration of reagent solutions, buffer clarification, and HPLC mobile phase preparation.

FAQ

Can the VF600 be used with corrosive solvents such as concentrated HCl or NaOH?
Yes—when equipped with chemically resistant membranes (e.g., PTFE or PVDF) and fluoropolymer-coated cup assemblies (optional upgrade); standard cups are rated for pH 2–12 and intermittent exposure to common organics.
Is vacuum level adjustable per channel?
No—vacuum is uniformly distributed across all six channels via a manifold; however, individual channel on/off control allows differential throughput management.
What maintenance is required for the integrated vacuum pump?
The diaphragm pump is oil-free and requires only periodic inspection of inlet filters and replacement of diaphragms every 12–18 months under continuous use—no lubrication or calibration needed.
Are replacement filtration cups supplied with membrane pre-installed?
Yes—disposable cup kits include sterilized, pre-mounted 47 mm membranes; alternative pore sizes (0.22 µm, 0.45 µm, 1.2 µm) and material types are available as configurable options.
Does the system meet CE or UL certification requirements?
The VF600 conforms to GB standards applicable to Class I laboratory equipment; CE marking is available upon request with EU Representative designation and EMC testing reports (EN 61326-1).
