CREATRUST CTLW-120P / CTLW-200P Fully Automated Laboratory Glassware Washer with Integrated Pure Water System

Overview

The CREATRUST CTLW-120P and CTLW-200P are fully integrated, benchtop-to-floor-standing laboratory glassware washers engineered for high-reproducibility cleaning, thermal disinfection, and on-demand pure water generation in a single, self-contained unit. Unlike conventional bottle washers requiring external purified water supply or softening infrastructure, these models incorporate an in-line reverse osmosis (RO) and activated carbon filtration system—designed to produce GB/T 6682–2008 Grade III compliant water (conductivity <5 µS/cm) directly from municipal tap feed. The system operates on a closed-loop principle: tap water undergoes pretreatment, RO membrane filtration, and final polishing before being used in both pre-rinse and final rinse cycles. Thermal disinfection is achieved via programmable hot-water circulation (up to 93°C) followed by forced convection drying using recirculated, HEPA-filtered hot air. This architecture eliminates dependency on third-party water systems, reduces facility footprint, and ensures consistent water quality traceability across wash cycles—critical for GLP-compliant laboratories and QC environments where residue control and validation integrity are mandatory.

Key Features

• On-board pure water generation system with real-time conductivity monitoring (displayed on integrated touchscreen interface), eliminating need for external DI/RO units or salt-based softeners.
• Modular pure water subsystem with standardized consumables (pre-filters, RO membranes, post-carbon cartridges) enabling rapid replacement and scheduled maintenance without system downtime.
• Automated water level management: system initiates pure water production when reservoir falls below set threshold and halts automatically upon reaching target volume—ensuring optimal storage and energy efficiency.
• Single-unit integration of washing, thermal disinfection (≥93°C hold time configurable per cycle), and hot-air drying (2.1 kW forced convection) within one chassis—no inter-module piping or electrical coordination required.
• Dual-stage spray arm design with adjustable pressure and rotational speed ensures uniform coverage across complex geometries including volumetric flasks, burettes, centrifuge tubes, and HPLC vials.
• Touchscreen HMI with cycle library support, password-protected user levels, and audit trail logging (optional USB export) compliant with basic data integrity requirements under ISO/IEC 17025 and FDA 21 CFR Part 11 Annex 11 principles.

Sample Compatibility & Compliance

The CTLW series accommodates standard laboratory glassware up to 1000 mL capacity—including Erlenmeyer flasks, graduated cylinders, pipette tips trays, Petri dishes, and reusable chromatography columns—on 12-tier adjustable racks. All internal wetted surfaces are constructed from 316L stainless steel and food-grade PEEK components resistant to alkaline detergents and thermal stress. The system meets national Chinese laboratory water standards (GB/T 6682–2008 Grade III) and delivers validated removal efficacy: ≥99% reduction in viable microorganisms (per ISO 15883-1 bioburden testing methodology), ≥99% organic residue clearance (verified by TOC analysis), ≥99% inorganic ion rejection (confirmed via ICP-OES), and ≥99% particulate removal (tested per ISO 21501-4 light scattering). While not certified to EN ISO 15883 or AAMI ST34, the unit’s operational parameters align with key performance indicators referenced in those standards for washer-disinfectors used in non-critical device reprocessing.

Software & Data Management

The embedded control firmware supports up to 20 customizable wash programs, each with independent configuration of fill volume, temperature ramp rate, dwell time, detergent dosing sequence, and drying duration. Cycle execution logs include timestamp, operator ID (if enabled), water conductivity values (inlet and rinse stages), temperature profiles, and fault codes—all stored locally for ≥12 months. Optional USB data export enables offline review and integration into LIMS or electronic lab notebooks (ELN). Audit trail functionality records all parameter modifications, program launches, and user logins with immutable timestamps—supporting compliance with ISO/IEC 17025 clause 7.10 and foundational elements of ALCOA+ data governance frameworks.

Applications

These washers serve analytical, pharmaceutical, environmental, and academic laboratories performing routine sample preparation where residual contamination compromises downstream analysis—such as ICP-MS trace metal quantification, HPLC method development, ELISA assay validation, and microbiological culture media preparation. Their integrated water system makes them especially suitable for satellite labs, mobile testing units, or facilities lacking centralized purified water infrastructure. The CTLW-200P variant—with its expanded 200 L chamber—is optimized for high-throughput core facilities processing >500 items per day, while the CTLW-120P offers space-efficient operation in smaller QA/QC labs or teaching environments requiring full-cycle automation without infrastructure retrofitting.

FAQ

Does the CTLW series require connection to a central purified water network?
No. It generates GB/T 6682–2008 Grade III water internally from standard tap water input.
Can detergent concentration be adjusted per cycle?
Yes—alkaline and neutral detergent dosing is programmable in 0.1% increments via the HMI interface.
Is validation documentation (IQ/OQ/PQ protocols) provided?
Standard delivery includes factory test reports and operational qualification templates; site-specific IQ/OQ/PQ support is available through authorized service partners.
What is the expected service life of the RO membrane under typical lab usage?
With proper pretreatment and annual preventive maintenance, RO membranes maintain ≥90% rejection efficiency for 24–36 months depending on local feed water hardness and chlorine exposure.
Are spare parts and consumables readily available outside China?
Yes—CREATRUST maintains regional distribution hubs in Southeast Asia, Europe, and North America for critical spares including filters, membranes, and spray arms.
