Overview
The Miele PG 8536 Professional Laboratory Glassware Washer is a CE-certified, fully automated cleaning and thermal disinfection system engineered for high-throughput, regulated laboratory environments. It operates on the principle of controlled spray-arm circulation combined with precisely regulated temperature profiles, detergent dosing, and multi-stage rinse cycles—including final ultra-pure water rinses—to achieve reproducible removal of organic residues, proteins, nucleic acids, and particulate contaminants from reusable labware. Designed in accordance with DIN EN ISO 15883-1 (washer-disinfectors for medical devices) and aligned with key requirements of CLSI EP21-A, ASTM E2577 (Standard Practice for Validation of Cleaning Processes), and EU Regulation (EC) No 1935/2004 for materials in contact with foodstuffs, the PG 8536 delivers validated cleaning efficacy suitable for GLP, GMP, and ISO/IEC 17025-accredited laboratories.
Key Features
- Stainless steel 316L chamber (175 L capacity) with reinforced door seal and pressure-tight locking mechanism for safe operation at elevated temperatures up to 93 °C
- Programmable multi-step cycle architecture: pre-wash, main wash (with enzymatic or alkaline detergent), intermediate rinse, thermal disinfection phase (≥80 °C for ≥1 min), final rinse with deionized or purified water, and forced-air drying
- Dual-dose detergent reservoir (5 L + 10 L configuration) enabling automatic, gravimetrically calibrated dispensing per cycle—minimizing human error and chemical overuse
- Integrated temperature, conductivity, and turbidity sensors providing real-time process monitoring and cycle traceability
- Touchscreen HMI with password-protected user levels (Operator, Technician, Administrator) and built-in audit trail compliant with FDA 21 CFR Part 11 requirements
- Energy-optimized heat recovery system reducing total power consumption by up to 25% compared to conventional lab washers
Sample Compatibility & Compliance
The PG 8536 accommodates standard laboratory glassware including volumetric flasks (up to 2 L), conical flasks (up to 1 L), graduated cylinders, pipettes (including serological and volumetric), Petri dishes, culture tubes, and borosilicate glass test tubes. Racks are configurable for high-density loading without compromising spray coverage. All program parameters—including dwell time, temperature ramp rate, detergent concentration, and rinse volume—are adjustable within validated operating ranges to meet application-specific cleaning validation protocols. The system supports IQ/OQ/PQ documentation packages and is compatible with third-party validation software for full lifecycle compliance management under ISO 13485, ISO 9001, and GxP frameworks.
Software & Data Management
Miele LabControl™ software (v3.2+) provides centralized remote monitoring, cycle scheduling, and electronic record archiving. Each completed cycle generates a timestamped PDF report containing start/stop times, peak temperature, conductivity readings, detergent usage, and pass/fail status against predefined acceptance criteria. Data export formats include CSV, XML, and PDF/A-2 for long-term archival. Audit logs retain all user actions—including parameter changes, login/logout events, and alarm acknowledgments—for minimum 12 months. Optional integration with LIMS via HL7 or REST API enables automatic transfer of cleaning metadata to sample tracking workflows.
Applications
- Pre-analytical preparation of glassware for HPLC, GC-MS, and ICP-MS analysis where trace metal contamination must be minimized
- Decontamination of biosafety level 2 (BSL-2) labware following exposure to pathogenic microorganisms or recombinant DNA constructs
- Routine cleaning of volumetric equipment in pharmaceutical QC labs requiring USP analytical instrument qualification
- Thermal disinfection of reusable pipette tips and centrifuge tubes in molecular biology core facilities
- Validation-supporting cleaning processes in clinical diagnostics labs subject to CAP/CLIA accreditation standards
FAQ
Does the PG 8536 support validation according to ASTM E2577?
Yes—the system includes programmable cycle variables, sensor-based verification points, and electronic record generation required for cleaning process validation per ASTM E2577 Annex A2.
Can purified water be used for the final rinse?
Yes—integrated inlet connections accept deionized, distilled, or filtered water up to 0.1 µS/cm conductivity; optional inline UV sterilization module available.
Is service documentation available in English?
All technical manuals, spare parts catalogs, and IQ/OQ templates are provided in English and updated quarterly via Miele’s secure customer portal.
What safety certifications does the unit hold?
CE-marked per Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU; additionally certified to UL 61010-1 and CSA C22.2 No. 61010-1 for North American installations.
How often does the detergent reservoir require refilling?
Based on average usage (12–15 cycles/day), the 10 L reservoir typically requires replenishment every 5–7 working days; low-level alerts are displayed on the HMI and logged in the audit trail.
