Foxx EZwaste™ Vacuum Waste Collection System

Overview

The Foxx EZwaste™ Vacuum Waste Collection System is an engineered solution for safe, compliant, and ergonomically optimized liquid waste management in analytical and preparative laboratory environments. Designed specifically for integration with high-performance liquid chromatography (HPLC), ultra-high-performance liquid chromatography (UHPLC), and other solvent-intensive instrumentation, the system operates under controlled vacuum aspiration to transport spent mobile phases and rinse solvents into chemically resistant HDPE collection vessels. Its core architecture adheres to fundamental principles of closed-system vacuum transfer—minimizing operator exposure, preventing atmospheric contamination, and ensuring consistent flow dynamics across variable viscosity and volatility profiles. Unlike open-bucket or gravity-fed alternatives, the EZwaste™ system maintains positive containment integrity throughout operation, supporting institutional adherence to OSHA 29 CFR 1910.1200 (Hazard Communication), EPA 40 CFR Part 262 (Hazardous Waste Determination), and laboratory-specific chemical hygiene plans.

Key Features

• Chemically inert high-density polyethylene (HDPE) EZGrip™ collection bottles available in five standard capacities: 2.5 L, 4 L, 5 L, 10 L, and 20 L—each featuring integrated ergonomic grips and wall-mounted stability ribs.
• Dual 83B VersaCap® sealing system: one open-cap configuration for continuous waste intake; one sealed-cap variant for secure transport and off-line disposal—enabling cap exchange without disconnection of waste tubing.
• Six standardized 3.2 mm (1/8″ OD) waste line ports with compression-style tube fittings, ensuring leak-tight connections across common PTFE, Tygon®, and stainless-steel fluid paths.
• Dedicated 1/4″ NPT port for integration with activated carbon emission filters (included), designed to adsorb volatile organic compounds (VOCs) including acetonitrile, methanol, THF, and chlorinated solvents at typical HPLC exhaust concentrations.
• 90° angled adapter included for vertical mounting compatibility with fume hoods, benchtop enclosures, or under-cabinet storage configurations—reducing footprint while preserving accessibility.
• Replaceable sulfurized EPDM gaskets rated for extended service life in contact with aggressive organic solvents, offering superior resistance compared to standard nitrile or silicone elastomers.
• Pre-installed filter housing with integral pressure-relief venting to prevent filter saturation-induced backpressure buildup during extended runs.

Sample Compatibility & Compliance

The EZwaste™ system is validated for use with aqueous, polar aprotic, and moderately nonpolar solvent systems commonly employed in reversed-phase, normal-phase, and ion-pairing chromatographic workflows. It is not intended for use with strong oxidizers (e.g., concentrated nitric acid), halogenated hydrocarbons above 60°C, or highly reactive alkyl lithium reagents. All components comply with FDA 21 CFR §177.1520 (HDPE food-contact compliance), UL 94 HB flammability rating, and RoHS Directive 2011/65/EU. The carbon filter meets ASTM D5228–18 standards for activated carbon iodine number and butane activity testing. System documentation supports GLP-compliant recordkeeping when paired with Foxx’s optional audit-trail-enabled vacuum controller modules (sold separately).

Software & Data Management

The EZwaste™ is a hardware-only passive collection platform and does not incorporate embedded firmware, onboard sensors, or digital connectivity. However, it is fully interoperable with third-party vacuum monitoring systems—including those from KNF, VACUUBRAND, and Agilent—that provide real-time pressure logging, runtime tracking, and maintenance alerts. When deployed alongside Foxx’s EzControl™ vacuum manifold controllers (optional), users gain access to event-stamped operational logs, filter replacement reminders, and CSV-exportable usage histories compatible with LIMS integration via OPC UA or Modbus TCP protocols. All mechanical interfaces conform to ISO 8573-1 Class 4 purity specifications for compressed air/vacuum lines.

Applications

• Centralized waste capture from multi-channel HPLC/UHPLC systems in QC/QA laboratories operating under cGMP (21 CFR Part 211) and ISO/IEC 17025 frameworks.
• Safe containment of acidic or basic mobile phase fractions during method development and column cleaning procedures.
• Reduction of ambient VOC exposure in shared analytical suites—particularly where ventilation infrastructure is limited or HVAC recirculation is employed.
• Transport and interim storage of collected waste prior to off-site hazardous waste manifesting per RCRA Subtitle C requirements.
• Integration into automated sample preparation workcells utilizing robotic liquid handlers and fraction collectors.

FAQ

What solvent types are compatible with the EZwaste™ system?

Acetonitrile, methanol, ethanol, isopropanol, tetrahydrofuran, dichloromethane, ethyl acetate, and aqueous buffers up to pH 12 are routinely used. Avoid concentrated mineral acids, sodium hypochlorite, and peroxide-forming ethers.
How often must the carbon filter be replaced?

Filter service life depends on total solvent volume, volatility profile, and average vapor pressure. Under typical HPLC conditions (1–2 mL/min flow, 60% ACN/water), replacement is recommended every 3–6 months or after 200 L of total waste volume.
Can multiple HPLC systems feed into a single EZwaste™ bottle?

Yes—up to six independent waste lines may be connected simultaneously using the six 1/8″ OD ports. Flow balancing is achieved via individual inline needle valves (not included) to prevent cross-contamination or siphoning.
Is the system suitable for radioactive or biohazardous waste?

No. The EZwaste™ is designed exclusively for chemical waste. Radioactive or biological waste requires dedicated containment systems meeting NRC or CDC biosafety level (BSL-2/3) specifications.
Does Foxx provide validation documentation for GxP environments?

Yes—IQ/OQ protocols, material certifications (USP Class VI, FDA-compliant HDPE), and filter performance test reports are available upon request for regulated installations.
