EURPING Q620 Laboratory Bottle Washer

Overview

The EURPING Q620 Laboratory Bottle Washer is an integrated, fully automated cleaning and rinsing system engineered for high-throughput, reproducible decontamination of glassware, plastic containers, and other reusable labware in regulated research, quality control, and clinical laboratory environments. Utilizing thermally controlled aqueous cleaning cycles—comprising pre-rinse, alkaline/acidic detergent wash, intermediate rinse, final hot-water rinse, and optional thermal drying—the Q620 delivers consistent, validated cleaning performance aligned with ISO 15883-1 (washer-disinfectors for medical devices) and GLP/GMP-relevant hygiene standards. Its 163 L stainless steel chamber accommodates up to 24 standard 1-L volumetric flasks or equivalent mixed loads, supporting batch processing without manual repositioning. Designed for standalone operation, the unit requires only standard water supply (with optional softener integration), power input (230 V / 50 Hz), and floor-level drainage—no external steam, compressed air, or auxiliary plumbing is necessary.

Key Features

• Chamber constructed from passivated 316L stainless steel (interior) and 304 stainless steel (exterior), ensuring long-term resistance to aggressive acidic and alkaline detergents, chlorinated solutions, and repeated thermal cycling.
• Integrated detergent storage: two internal 5 L reservoirs accommodate separate acidic and alkaline formulations, minimizing cross-contamination risk and eliminating external dispensing hardware.
• High-capacity recirculation system: 400 L/min main circulation pump generates uniform spray pressure across all rack positions; adjustable nozzle orientation ensures complete coverage of complex geometries (e.g., narrow-neck bottles, graduated cylinders).
• Microprocessor-based control system with full-color capacitive touchscreen interface; 18 pre-programmed cycles (including USP compliant methods for pharmaceutical glassware) and 79 user-configurable protocols with editable temperature profiles, dwell times, detergent dosing sequences, and rinse counts.
• Dual safety architecture: electromagnetic door lock + mechanical interlock prevents chamber access during active heating or pressurized rinse phases; real-time temperature monitoring triggers automatic shutdown if >85 °C is detected.
• Comprehensive fluid management: built-in flowmeter, liquid level sensor, conductivity-based detergent concentration feedback, salt-level monitoring for integrated softener, and low-detergent alert with audible/visual notification.

Sample Compatibility & Compliance

The Q620 accommodates a broad range of laboratory vessels—including borosilicate glassware (volumetric flasks, pipettes, burettes, culture tubes), polypropylene and polycarbonate containers, stainless steel tools, and silicone tubing—without deformation or surface degradation. All wash programs are compatible with common laboratory-grade detergents (e.g., Alconox®, Liquinox®, Hellmanex®) and meet ASTM E2574-22 requirements for cleaning validation documentation. The system supports audit-ready operation under FDA 21 CFR Part 11 when paired with compliant data logging software: electronic signatures, time-stamped cycle records, parameter deviation alerts, and immutable export of CSV-formatted logs via RS232 serial interface.

Software & Data Management

Cycle execution data—including start/stop timestamps, actual vs. setpoint temperatures, detergent dosage volumes, flow rates, and door lock status—are recorded in non-volatile memory. The RS232 port enables direct connection to dot-matrix printers for hard-copy cycle reports or integration with LIMS/LabWare platforms using ASCII protocol. All records include unique cycle IDs, operator login credentials (via optional PIN authentication), and checksum-verified integrity fields. Data retention spans ≥10,000 cycles; archived logs can be exported without proprietary software, facilitating third-party review and regulatory inspection readiness.

Applications

• Pharmaceutical QC labs: residue removal from HPLC vials, dissolution apparatus parts, and stability study containers per ICH Q5C guidelines.
• Clinical diagnostics: decontamination of specimen collection tubes and centrifuge buckets prior to reuse under CLIA-certified workflows.
• Environmental testing labs: cleaning of EPA Method 500/600-series sample bottles to prevent carryover in trace metal or organic contaminant analysis.
• Academic research cores: high-volume turnover of teaching lab glassware with repeatable, instructor-defined cleaning protocols.
• Biotech process development: sanitization of single-use bioreactor accessories and buffer preparation vessels between batches.

FAQ

Does the Q620 support validation documentation required for GMP environments?
Yes—cycle parameters are logged with millisecond timestamp resolution, and all deviations trigger automatic flagging. When configured with optional audit-trail software, it meets FDA 21 CFR Part 11 and EU Annex 11 requirements.
Can the unit operate with hard municipal water?
It includes an integrated softener with salt-level sensing and low-salt alarm; bypassing softening is not recommended for sustained operation due to scale accumulation risk in heaters and nozzles.
Is remote monitoring or Ethernet connectivity available?
The standard configuration includes RS232 only; Ethernet or Wi-Fi modules are available as factory-installed options (Q620-ETH variant) with Modbus TCP or HTTP API support.
What maintenance intervals are recommended?
Daily: filter cleaning and visual inspection of spray arms. Quarterly: descaling of heat exchanger and calibration verification of temperature sensors. Annually: full pump and valve assembly inspection per EURPING Service Bulletin SB-Q620-2023.
Are replacement racks and custom fixtures available?
Yes—EURPING offers OEM-designed racks for specific vessel types (e.g., NMR tubes, microcentrifuge tubes, filtration flasks) and provides CAD-based custom fixture design services upon request.
