Esco ELGW Series Fully Automatic Laboratory Glassware Washer

Overview

The Esco ELGW Series Fully Automatic Laboratory Glassware Washer is an engineered solution for high-throughput, reproducible cleaning and thermal disinfection of laboratory glassware and plasticware in regulated and non-regulated environments. Based on the principle of validated thermal cleaning—combining precisely controlled high-temperature water circulation (up to 99 °C), high-pressure spray dynamics (800 L/min flow rate), and chemically optimized cleaning agents—the system delivers consistent removal of organic residues, particulates, and microbiological contaminants. Designed for compliance-critical workflows, it supports routine cleaning of volumetric flasks, pipettes, test tubes, HPLC vials, and other standard labware without manual intervention. Its dual-chamber architecture (200 L and 220 L variants) accommodates large batch loads while maintaining uniform exposure to cleaning media across all rack positions. The washer operates under fully automated sequences—from fill, pre-rinse, detergent dosing, main wash, intermediate rinse, final rinse with conductivity-monitored ultrapure water, thermal disinfection, and HEPA-filtered hot-air drying—ensuring process repeatability and audit readiness.

Key Features

• 316L stainless steel chamber and dual-layer rotating spray arms engineered for corrosion resistance and complete 360° coverage—eliminating blind spots during cleaning cycles.
• SMARTSENSE microprocessor control system with a 7-inch full-color touchscreen interface, supporting both English and Chinese languages, intuitive navigation, and real-time cycle status monitoring.
• 15 factory-preset wash programs compliant with common industry protocols (e.g., ISO 15883-1, ASTM E2457), plus up to 100 user-defined programs with adjustable temperature, time, pressure, and chemical dosing profiles.
• Three-level password-protected access control (Operator, Supervisor, Administrator) enabling role-based system configuration, parameter locking, and secure audit trail management.
• Integrated conductivity sensor for final rinse water quality verification—optionally configurable to halt cycle completion if resistivity falls below user-specified thresholds (e.g., ≥10 MΩ·cm).
• HEPA-filtered hot-air drying system with adjustable temperature (ambient to 120 °C), minimizing recontamination risk and ensuring rapid, residue-free drying of heat-stable items.
• Emergency stop button with hardware-level circuit interruption, power-loss memory function, and automatic resume capability after brief outages.

Sample Compatibility & Compliance

The ELGW series is validated for cleaning a broad spectrum of laboratory consumables, including borosilicate glassware (volumetric flasks, burettes, beakers), polypropylene and polycarbonate plasticware (pipette tips, centrifuge tubes), stainless steel tools, and HPLC autosampler vials. It meets mechanical and thermal performance criteria outlined in ISO 15883-1 (washer-disinfectors for medical devices) and aligns with general laboratory equipment validation practices per ICH Q5A, USP , and EU GMP Annex 15. While not intended for sterile processing or clinical device reprocessing, its programmable parameters and data logging capabilities support IQ/OQ/PQ documentation for GLP and GMP-aligned laboratories. All units are CE-marked and comply with IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) standards.

Software & Data Management

Data integrity is maintained through embedded USB export functionality, enabling traceable download of cycle logs—including start/stop timestamps, temperature/pressure profiles, detergent usage, conductivity readings, and operator ID. Each log entry is digitally signed and time-stamped, supporting 21 CFR Part 11 compliance when integrated with validated laboratory information management systems (LIMS). Optional printer connectivity allows hard-copy record generation for immediate review. Firmware updates are performed via secure USB upload, preserving configuration integrity and version history. Cycle data can be mapped to internal SOP identifiers, facilitating root cause analysis during deviation investigations.

Applications

This washer serves pharmaceutical QC/QA labs performing residual solvent or active pharmaceutical ingredient (API) carryover validation; biotechnology facilities requiring endotoxin-free glassware for cell culture preparation; food safety testing laboratories adhering to AOAC or ISO/IEC 17025 accreditation requirements; academic research cores managing shared instrumentation; and municipal water treatment labs handling heavy-metal or nutrient analysis glassware. Its flexibility supports both routine daily cleaning and method-specific decontamination (e.g., RNase/DNase removal, pesticide residue elimination) through customizable thermal and chemical parameters.

FAQ

Is the ELGW washer suitable for cleaning silicone or rubber components?
No—silicone tubing, rubber stoppers, and similar elastomeric materials are not recommended due to potential degradation at elevated temperatures and exposure to alkaline detergents.
Can the system be integrated into a central building management system (BMS)?
Yes—dry-contact relay outputs and Modbus RTU (RS-485) communication ports are available as optional configurations for remote status monitoring and alarm integration.
What validation documentation is provided with the unit?
Each shipment includes Factory Acceptance Test (FAT) reports, electrical safety certification, material certificates for 316L stainless steel, and a blank IQ/OQ protocol template aligned with ISO/IEC 17025 and ASTM E2500 guidelines.
Does the washer meet environmental sustainability standards?
It features adaptive water heating control, low-flow rinse optimization, and programmable idle-mode power reduction—contributing to reduced utility consumption per cycle compared to legacy batch washers.
Is remote diagnostics supported?
Remote firmware troubleshooting and parameter diagnostics are available via secured Ethernet connection under Esco’s authorized service agreement, subject to customer network policy approval.
