Steelco LAB 600D Laboratory Bottle Washer and Thermal Disinfector

Overview

The Steelco LAB 600D is a CE-marked, fully automated laboratory bottle washer and thermal disinfector engineered for high-reproducibility cleaning, rinsing, thermal disinfection (≥93 °C), and HEPA-filtered hot-air drying of glassware and reusable labware. Designed in accordance with the stringent requirements of EN ISO 15883-1 and -2 for washer-disinfectors used in healthcare and laboratory environments, the LAB 600D employs a validated thermodynamic process cycle—comprising pre-wash, main wash, intermediate rinse, final rinse, thermal disinfection, and controlled drying—to ensure microbiological safety and residue-free surfaces. Its chamber architecture, constructed entirely from electropolished AISI 316L stainless steel with seamless, welded-free corners and sloped floor geometry, eliminates crevices where biofilm or particulate residues may accumulate—critical for GLP/GMP-aligned laboratories requiring traceability and contamination control.

Key Features

• Triple-source water inlet system (cold, hot, and deionized) enables optimized cycle timing and energy efficiency by selecting the appropriate feed temperature per phase;
• Dual PT1000 platinum resistance temperature sensors—one for real-time display, one for closed-loop disinfection temperature control—ensuring compliance with EN ISO 15883-defined thermal validation thresholds;
• Four programmable peristaltic detergent dosing pumps (2 standard, expandable to 4) calibrated for precise delivery of alkaline and acidic formulations per manufacturer specifications or internal SOPs;
• Three-tier adjustable basket rack system: upper rack height configurable to 140 mm or 210 mm; lower rack accommodates vessels up to 170 mm height; total usable basket volume: 170 L within a 200 L chamber;
• Integrated steam condenser eliminates need for external venting, reducing installation footprint and enabling safe operation in non-ducted lab spaces;
• Double-insulated door with thermal break reduces surface temperature and acoustic emission (<56 dB[A]) while minimizing heat loss during extended cycles;
• Self-diagnostic firmware with audible alarm and on-screen fault code display (e.g., low water level, pump failure, temperature deviation) supports rapid root-cause identification and service intervention;
• RS232 serial interface enables full cycle parameter logging, remote program upload/download, and integration with lab-wide data management systems—including audit trail generation compliant with FDA 21 CFR Part 11 when paired with validated software platforms.

Sample Compatibility & Compliance

The LAB 600D accommodates a comprehensive range of reusable laboratory vessels—including borosilicate glass test tubes, serological pipettes, Petri dishes, Erlenmeyer flasks, volumetric flasks, beakers, and custom-shaped apparatus—without mechanical abrasion or thermal shock. Its open-basket design and uniform spray arm distribution (with adjustable nozzle orientation) ensure complete wetting and turbulent flow across complex geometries. All operational parameters—including dwell times, temperature profiles, detergent concentration, and airflow velocity—are fully programmable and lockable to meet ISO/IEC 17025 method validation requirements. The system is certified to EN 61010-1 (electrical safety), EN 61010-2-040 (particular safety for laboratory equipment), and EN 61326 (EMC), ensuring robust electromagnetic compatibility in shared instrumentation environments.

Software & Data Management

Equipped with an intuitive LED-based human-machine interface (HMI), the LAB 600D stores up to 40 cleaning programs—20 factory-default and 20 user-defined—with editable setpoints for temperature, duration, pump activation, and drying parameters. Cycle execution is logged with timestamps, actual vs. setpoint values, and error flags. Via RS232, raw logs can be exported to CSV or integrated into LIMS or ELN platforms. When deployed with Steelco’s optional validation-ready software suite, the unit supports electronic signatures, user access levels (operator, supervisor, administrator), and immutable audit trails—meeting GLP, GMP, and ISO 13485 documentation expectations for regulated pharmaceutical and clinical research labs.

Applications

The LAB 600D serves as a critical infrastructure component in quality control laboratories (QC), analytical development units, biopharmaceutical manufacturing cleanrooms, academic core facilities, and contract research organizations (CROs). It replaces manual washing for applications demanding strict repeatability—such as HPLC vial preparation, cell culture flask reconditioning, or residual solvent removal prior to GC-MS analysis. Its validated thermal disinfection step satisfies USP sterility assurance requirements for non-sterile compounding areas and supports risk-based approaches to contamination control under ICH Q5C and Q9 frameworks. In environmental and food safety labs, it ensures consistent removal of organic matrix interferences prior to elemental analysis by ICP-MS or AAS.

FAQ

Does the LAB 600D comply with FDA or EU regulatory standards for use in GxP environments?
Yes—the device meets EN ISO 15883-1/-2 for washer-disinfectors and includes hardware and interface features (RS232, audit-ready logging, user-level access control) that support qualification (IQ/OQ/PQ) and alignment with FDA 21 CFR Part 11, EU Annex 11, and ISO 13485 requirements.
Can the machine be validated for specific cleaning protocols?
Absolutely—Steelco provides validation documentation packages, including DQ templates, FAT/SAT protocols, and cycle development guidance. Users may perform residue testing (e.g., TOC, conductivity, protein assay) and generate validation reports per ASTM E3085 or PDA TR35.
What maintenance intervals are recommended?
Daily visual inspection of filters and door gasket; weekly cleaning of the three-stage stainless steel filter assembly; quarterly calibration verification of PT1000 sensors and detergent pump output; annual preventive maintenance by certified Steelco service engineers.
Is deionized water mandatory for final rinse?
Not mandatory—but strongly recommended for applications sensitive to ionic residue (e.g., trace metal analysis, electrochemical cell preparation); the triple-inlet architecture allows automatic selection based on programmed phase logic.
How is drying performance verified?
HEPA-filtered air flow rate and temperature uniformity across the chamber are mapped during OQ using calibrated thermal probes; drying efficacy is confirmed via moisture-sensitive indicators or gravimetric residual water testing per ISO 15883-5 Annex C.
