Miele PG8504 Laboratory Bottle Washer

Overview

The Miele PG8504 Laboratory Bottle Washer is a fully automated, closed-loop cleaning system engineered for precision, reproducibility, and regulatory compliance in demanding analytical and quality control laboratories. Designed according to the principles of validated thermal cleaning dynamics, it employs controlled water circulation, precisely regulated temperature ramping (up to 70 °C), and programmable detergent dosing to remove organic residues, particulates, and trace contaminants from glassware, plasticware, ceramic vessels, and reusable labware—including volumetric flasks, pipettes, centrifuge tubes, reaction vessels, and sampling bottles. Unlike manual washing or generic dishwashers, the PG8504 operates under documented, repeatable cycles that eliminate operator variability and minimize human exposure to hazardous solvents or biohazards—supporting occupational safety (OSHA/NIOSH guidelines) and aligning with ISO 15883-1 for washer-disinfectors used in laboratory settings.

Key Features

• 175-liter stainless-steel chamber with seamless, laser-welded interior surfaces—engineered to prevent microbial harborage and ensure cleanability per ISO 13485 and FDA guidance on equipment design.
• Multi-stage filtration system including 5-µm pre-filtration, activated carbon polishing, and optional ultrafiltration modules to maintain rinse water purity and prevent redeposition of particles.
• Programmable cleaning protocols with up to 12 user-defined cycles; each cycle logs temperature profiles, pump pressure, conductivity, and detergent concentration for audit readiness.
• Integrated detergent and neutralizer dosing pumps with gravimetric calibration capability—compatible with Miele-certified low-foaming, residue-free alkaline and acidic formulations.
• Ergonomic loading configuration with adjustable rack systems (standard and custom) supporting simultaneous processing of heterogeneous vessel types without cross-contamination.
• Energy- and water-efficient architecture: average water consumption ≤ 12 L/cycle; heat recovery module reduces thermal load on HVAC infrastructure.

Sample Compatibility & Compliance

The PG8504 accommodates a broad spectrum of laboratory containers—from narrow-neck borosilicate glassware (e.g., NMR tubes, HPLC vials) to large-volume carboys and filtration assemblies. Its mechanical action combines optimized spray arm geometry (360° rotating nozzles) with variable pressure delivery (0.2–0.6 bar) to ensure complete wetting and particle removal—even from complex geometries such as serological pipettes or fritted funnels. The system meets key international standards for laboratory reprocessing, including ISO 15883-1 (washer-disinfectors), EN 61000-6-3 (EMC), and IEC 61010-1 (safety requirements for electrical equipment). Optional IQ/OQ documentation packages support GLP, GMP, and ISO/IEC 17025 accreditation workflows, while built-in cycle validation tools assist in meeting USP , ASTM E2573, and EU Annex 1 requirements for sterile and non-sterile preparation environments.

Software & Data Management

Equipped with Miele LabControl™ v4.2 firmware, the PG8504 provides full-cycle digital traceability via an intuitive touchscreen interface with multilingual support (English, German, French, Spanish). All operational parameters—including time stamps, temperature curves, conductivity readings, and error logs—are stored internally for ≥12 months and exportable via USB or Ethernet (TCP/IP) to LIMS or ELN platforms. Audit trail functionality complies with FDA 21 CFR Part 11 requirements through role-based access control (three-tier user permissions), electronic signatures, and immutable data logging. Optional remote monitoring via Miele Cloud Connect enables real-time status alerts and predictive maintenance scheduling based on usage analytics.

Applications

The PG8504 serves critical functions across pharmaceutical QC labs (USP method validation, residual solvent removal), clinical diagnostics (pre-analytical sample tube decontamination), environmental testing (EPA Method 500-series glassware cleaning), and academic research facilities requiring trace-metal-free preparation (ICP-MS, AAS). It is routinely deployed in cleanrooms (ISO Class 5–8), biosafety level 2+ labs handling low-to-moderate risk agents, and contract research organizations performing method transfer studies where cleaning validation is integral to analytical method robustness.

FAQ

Does the PG8504 support cleaning validation per FDA or ISO standards?
Yes—Miele provides IQ/OQ documentation templates, cycle development services, and thermocouple mapping kits aligned with ASTM E2573 and ISO 15883-2 for performance qualification.
Can it process plastic labware without deformation?
Yes—temperature ramping profiles and low-pressure rinse phases are configurable to accommodate polypropylene, polycarbonate, and PTFE components without warping or leaching.
Is third-party detergent compatibility supported?
Only Miele-certified detergents are validated for use; non-certified formulations may compromise filtration integrity, corrosion resistance, or residue limits.
What maintenance intervals are recommended?
Daily filter cleaning, quarterly descaling (using Miele Descale Plus), and annual service by Miele-certified technicians—tracked automatically via the onboard maintenance scheduler.
How does it integrate with existing lab informatics systems?
Via standard OPC UA or HL7 interfaces, or through CSV/XML exports compatible with major LIMS (e.g., LabWare, Thermo Fisher SampleManager, Veeva Vault).
