Miele SlimLine PLW 7111 Laboratory Bottle Washer

Overview

The Miele SlimLine PLW 7111 is a high-performance, CE-compliant laboratory bottle washer engineered for precision cleaning and thermal disinfection of reusable glassware, plastic containers, and modular labware in regulated research, quality control, and clinical laboratory environments. Designed according to DIN EN ISO 15883-1 and validated against DIN EN ISO 15883-4 standards for washer-disinfectors, the PLW 7111 employs a closed-loop, multi-stage wash cycle—including pre-rinse, alkaline detergent wash, intermediate rinse, thermal disinfection (≥90 °C hold for ≥1 minute), final rinse with deionized water, and forced-air drying—to ensure consistent removal of organic residues, particulates, and microbiological contaminants. Its compact 650 mm cabinet width enables seamless integration into narrow laboratory alcoves or under-bench configurations without compromising chamber volume (316 L) or load capacity—capable of processing up to 50 L of mixed-volume bottles per cycle.

Key Features

• Ultra-Slim Footprint: 650 mm width and 1965 mm height allow installation in space-constrained labs while maintaining full-size chamber volume and ergonomic loading height.
• EasyLoad™ Modular Basket System: Interchangeable basket configurations—including tall-bottle racks, beaker trays, pipette holder inserts, and customizable grid panels—support heterogeneous loads (e.g., volumetric flasks, centrifuge tubes, reagent bottles) without requiring tool-based adjustments.
• Full-Glass Front Panel with Status-Responsive LED Illumination: Transparent door provides real-time visual monitoring; integrated cavity lighting shifts color dynamically—blue during active washing, green upon cycle completion, red for fault conditions—enabling immediate operational status recognition without interface interaction.
• Thermal Disinfection Validation Ready: Built-in PT100 temperature sensors at multiple chamber zones (bottom, mid, top) log time-temperature profiles compliant with EN ISO 15883-4 Annex A for process verification and audit readiness.
• Chemical Dosing Precision: Dual-dose peristaltic pumps deliver programmable volumes of neutral, alkaline, and acidic detergents with ±2% volumetric accuracy, minimizing carryover and optimizing detergent economy.
• Robust Stainless Steel Construction: AISI 316L inner chamber, double-walled insulated housing, and IP54-rated electrical components ensure long-term corrosion resistance and compliance with GLP/GMP facility requirements.

Sample Compatibility & Compliance

The PLW 7111 accommodates standard and custom laboratory vessels up to 50 L in volume, including borosilicate glass bottles (e.g., Duran®, Kimax®), polypropylene carboys, stainless steel containers, and autoclavable plasticware rated for repeated thermal cycling. It supports validation protocols aligned with ISO 13485 (for medical device manufacturing), USP (sterile processing), and FDA 21 CFR Part 11 when paired with optional Miele LabConnect™ software (see Software & Data Management). All wash programs meet DIN EN ISO 15883-1 mechanical and thermal efficacy criteria, and the unit carries CE marking under the EU Medical Device Regulation (MDR) Annex VIII Class Ir classification for washer-disinfectors used in non-implantable device reprocessing.

Software & Data Management

Equipped with Miele’s LabControl™ touchscreen HMI (7″ capacitive display), the PLW 7111 offers 20 factory-programmed and 10 user-definable cycles, each with adjustable parameters (temperature ramp rates, dwell times, spray pressure, final rinse conductivity thresholds). Optional LabConnect™ software enables networked remote monitoring, electronic batch record generation, and secure data export (CSV/PDF) with embedded digital signatures. When configured with audit trail and electronic signature modules, the system satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures, supporting traceability across GxP environments. Cycle logs include timestamped temperature curves, detergent dosing events, door open/close history, and error diagnostics—all stored locally for ≥12 months.

Applications

• Preparation of trace-metal-free glassware for ICP-MS and AAS analysis
• Residue removal from HPLC vials, GC autosampler vials, and reaction flasks prior to reuse
• Thermal disinfection of reusable media bottles and buffer containers in cell culture facilities
• Cleaning validation support for pharmaceutical QC laboratories operating under EU GMP Annex 15
• High-throughput decontamination of sample collection bottles in environmental testing labs (EPA Method 500 series)
• Standardized cleaning of volumetric glassware in metrology and reference material production labs

FAQ
