STIER C3000/C300CD Laboratory Glassware Washer

Overview

The STIER C3000 and C300CD are fully automated laboratory glassware washers engineered for reproducible, traceable, and validation-ready cleaning of critical labware in mid-to-large-scale research, quality control, and regulated manufacturing environments. Based on validated thermal and chemical cleaning principles—combining precisely controlled water temperature cycles (up to 93°C), programmable multi-stage rinse protocols, and detergent dosing via peristaltic pumps—the system delivers consistent removal of organic residues, particulates, and bioburden from a wide range of vessel geometries. Unlike manual or semi-automated methods, the C3000 series implements closed-loop process control with real-time monitoring of key parameters including fill level, temperature ramp profiles, conductivity during final rinses, and detergent delivery accuracy—ensuring compliance with ISO 15883-1 (washer-disinfectors for medical devices) and supporting alignment with GLP, GMP, and FDA 21 CFR Part 11 requirements when paired with optional audit-trail-capable software.

Key Features

• 185-liter stainless steel chamber constructed from corrosion-resistant 316 stainless steel, with 304 stainless steel exterior featuring anti-fingerprint surface treatment for durability and cleanroom compatibility.
• Dual-voltage power architecture (3N AC 380 V / AC 220 V, 50 Hz) enables flexible installation across diverse facility electrical infrastructures without external transformers.
• Integrated soft water generator and steam condenser eliminate scale formation and reduce ambient humidity—critical for stable performance in high-throughput labs.
• Residual-heat drying eliminates dedicated heating elements during the drying phase, reducing energy consumption while maintaining thermal stability and minimizing thermal stress on sensitive glassware.
• Standard built-in detergent level sensor and precision peristaltic dispensing pump ensure repeatable chemical dosing across cycles, supporting method transfer and SOP adherence.
• Noise emission limited to ≤70 dBA at 1 m distance, meeting occupational safety standards for continuous operation in shared laboratory spaces.

Sample Compatibility & Compliance

The C3000 accommodates up to three independently configurable rack levels, enabling simultaneous processing of heterogeneous labware loads: Level 1 supports large-format vessels (volumetric flasks ≥2 L, wide-mouth bottles, beakers ≥1 L); Level 2 handles standard analytical glassware (volumetric flasks 10–1000 mL, screw-cap vials, autosampler vials, graduated cylinders); Level 3 is optimized for flatware and small instruments (Petri dishes, culture plate lids, forceps, scissors, pipette tips trays). All cycles comply with EN ISO 15883-1 Annex C for washer-disinfector performance verification and support IQ/OQ/PQ documentation packages. Optional conductivity sensors and HEPA filtration modules extend functionality for applications requiring endotoxin-free rinsing or ISO Class 5–7 cleanroom integration.

Software & Data Management

The C3000 features an embedded PLC-based controller with intuitive touch interface, storing up to 20 customizable wash programs with adjustable parameters (pre-wash duration, main wash temperature/duration, number/temperature of intermediate and final rinses, drying time). Cycle logs—including start/end timestamps, temperature curves, detergent volume dispensed, and fault codes—are retained onboard for ≥10,000 cycles. When equipped with the optional Ethernet module and STIER LabControl™ software, the system provides full electronic recordkeeping, user access management, digital signature capability, and 21 CFR Part 11-compliant audit trails—including operator ID, parameter changes, and cycle execution status—for regulatory submissions and internal quality audits.

Applications

This washer serves laboratories engaged in pharmaceutical development (API synthesis, formulation QC), clinical diagnostics (clinical chemistry, microbiology), environmental testing (EPA Method 500-series sample prep), food safety (AOAC-certified residue analysis), and academic research requiring high-integrity cleaning prior to ICP-MS, HPLC, or cell culture workflows. Its ability to process volumetric glassware without distortion, remove trace detergent residues verified by conductivity monitoring, and maintain thermal uniformity across the entire chamber makes it suitable for cleaning labware used in USP Analytical Instrument Qualification and ASTM E2878-13 validation frameworks.

FAQ

What types of laboratory glassware can be cleaned in one cycle?
The C3000 supports mixed-load configurations across three rack levels—allowing volumetric flasks, beakers, Petri dishes, and surgical instruments to be processed simultaneously without cross-contamination risk.
Is validation support documentation available?
Yes—STIER provides IQ/OQ templates, calibration certificates for integrated sensors, and technical files aligned with ISO 15883-1 and EU MDR Annex I essential requirements.
Can the system be integrated into a centralized lab automation network?
With optional Ethernet connectivity and Modbus TCP protocol support, the C3000 interfaces with LIMS and MES platforms for automated job dispatch and status reporting.
What maintenance intervals are recommended?
Routine inspection every 6 months includes softener resin replacement, steam condenser descaling, and detergent pump calibration—detailed in the bilingual (EN/CN) service manual provided with shipment.
