Steelco LAB 610D Laboratory Bottle Washer and Thermal Disinfector

Overview

The Steelco LAB 610D is a CE-certified, Class B laboratory bottle washer and thermal disinfector engineered for reproducible, traceable, and validated cleaning of glassware and reusable labware in regulated environments. Designed according to the principles of thermodynamic cycle control and fluid-dynamic rinsing efficacy, it operates on a fully automated, programmable sequence comprising pre-wash, main wash, intermediate rinse, final rinse, thermal disinfection (at ≥93 °C for ≥5 minutes, compliant with EN ISO 15883-1/-2), and HEPA-filtered hot-air drying. Its core architecture integrates process-critical hardware—including dual independent PT1000 platinum resistance thermometers, precision peristaltic dosing pumps, and a three-stage stainless steel filtration system—to ensure consistent thermal profiles, detergent concentration accuracy, and mechanical removal of particulate and organic residues. The unit is intended for use in GLP, GMP, and ISO 17025-accredited laboratories where cleaning validation, audit readiness, and personnel safety are non-negotiable requirements.

Key Features

• AISI 316L mirror-finished stainless steel chamber (250 L volume) with seamless, weld-free sloped bottom and rounded internal corners—minimizing residue retention and enabling full CIP-compatible cleanability.
• Dual high-accuracy PT1000 temperature sensors: one for real-time display and process monitoring, the other dedicated to closed-loop disinfection temperature control at 93 °C ±1 °C.
• Four-tier basket rack system with height-adjustable middle shelf (configurable for 60/160 mm or 130/230 mm vessel clearance), supporting standardized and custom labware up to 540 × 590 × 780 mm internal chamber dimensions.
• RS232 serial interface enabling bidirectional program upload/download, real-time cycle parameter logging, fault diagnostics, and optional thermal printer integration for permanent record generation.
• HEPA-class (H13) filtered drying system with adjustable air temperature (20–140 °C), ensuring low-bioburden, particle-free drying without condensation or recontamination.
• Integrated steam condenser eliminating need for external venting—reducing installation complexity and facility HVAC load.
• Triple-stage stainless steel filtration (coarse/mid/fine mesh) protecting circulation pump and extending service intervals under high-soil-load conditions.
• Acoustic insulation and dual-layer door construction achieving ≤57.5 dB(A) operational noise—suitable for shared laboratory spaces.

Sample Compatibility & Compliance

The LAB 610D accommodates standard and irregular labware including volumetric flasks, Erlenmeyer flasks, beakers, graduated cylinders, Petri dishes, pipettes, test tubes, and culture bottles—provided dimensional constraints are observed (max. height per shelf as specified). It supports connection to cold water, hot water (≤60 °C), and deionized water supplies, enabling optimized multi-source fill strategies that reduce cycle time and energy consumption. All operational parameters—including temperature profiles, dwell times, detergent dosage, and airflow rates—are fully programmable and auditable. The system meets essential safety and performance standards: EN ISO 15883-1/-2 (for washer-disinfectors), EN 61010-1 (electrical safety), EN 61010-2-040 (particular requirements for laboratory equipment), EN 61326 (EMC), and relevant EU Machinery and Low Voltage Directives. Optional IQ/OQ documentation packages are available to support qualification under FDA 21 CFR Part 11 and EU Annex 15 guidelines.

Software & Data Management

The embedded microprocessor controller provides intuitive operation via a backlit LCD interface with multilingual menu navigation. It stores up to 40 programs: 20 factory-configured cycles (e.g., “Glassware Heavy Soil”, “Plasticware Low-Temp”, “Sterile Media Vessels”) and 20 user-defined protocols. Each program defines precise setpoints for fill volume, temperature ramp rate, hold duration, pump speed, and drying profile. All cycle executions generate timestamped logs—including start/stop time, actual temperatures, detergent dispense volume, fault codes, and operator ID (if connected to networked access control). RS232 output supports integration with LIMS or electronic lab notebooks (ELN) for ALCOA+ data integrity compliance. Audit trail functionality records all parameter modifications, user logins, and alarm events—enabling full traceability during regulatory inspections.

Applications

The LAB 610D serves critical cleaning and disinfection workflows across pharmaceutical QC/QA labs, biotechnology R&D facilities, clinical diagnostic centers, food safety testing laboratories, and academic research institutes. Typical applications include preparation of glassware for HPLC/GC sample introduction, sterilization of media containers prior to autoclaving, decontamination of biosafety level 2 (BSL-2) labware after microbial handling, and routine cleaning of volumetric equipment requiring metrological traceability. Its validated thermal disinfection step satisfies requirements for non-sterile but microbiologically controlled processing environments—particularly where chemical disinfectants are incompatible with downstream analytical methods or material compatibility is constrained.

FAQ

Does the LAB 610D meet FDA or EU GMP cleaning validation requirements?
Yes—when operated with documented IQ/OQ protocols, calibrated sensors, and validated cleaning cycles, it supports compliance with FDA 21 CFR Part 11, EU GMP Annex 15, and ISO 13485 cleaning validation frameworks.
Can the machine be integrated into a central water supply system?
Yes—it accepts simultaneous connections to cold water, pre-heated water (≤60 °C), and deionized water lines, allowing dynamic source selection per phase to optimize energy use and rinse efficiency.
What maintenance intervals are recommended for the filtration system and pumps?
The triple stainless steel filter requires manual cleaning after every 10–15 cycles under typical lab loading; the peristaltic pumps undergo preventive replacement every 12 months or 2,000 operating hours, whichever occurs first.
Is remote monitoring or Ethernet connectivity supported?
Standard RS232 enables local PC-based monitoring; optional RS485 or Ethernet modules (with Modbus TCP or OPC UA support) are available for enterprise-level integration.
How is temperature uniformity verified across the chamber during disinfection?
Temperature mapping studies using calibrated thermocouples (per ISO 15883-2 Annex C) are required during qualification; the dual PT1000 sensor architecture ensures redundancy and cross-verification of thermal performance.
