Yonghe Chuangxin CTLW-60 Benchtop Laboratory Bottle Washer

Overview

The Yonghe Chuangxin CTLW-60 is a compact, fully automated benchtop bottle washer engineered for precision cleaning and thermal disinfection of small- to medium-volume laboratory glassware and plasticware. Designed specifically for space-constrained environments—including retrofit installations in legacy laboratories—the CTLW-60 employs a closed-loop, high-efficiency spray-arm system that delivers 360° targeted high-pressure water jets to both interior and exterior surfaces of labware. Its cleaning mechanism integrates mechanical action (dynamic impingement), thermal energy (programmable heating up to 93 °C), and optimized detergent chemistry to achieve reproducible removal of organic residues, particulates, and trace contaminants. The system meets fundamental requirements for cleanroom-adjacent workflows and supports routine preparation of analytically clean vessels compliant with ISO 13485, GLP, and internal QC protocols.

Key Features

• Compact footprint (530 × 646 × 646 mm) enables flexible placement on countertops or under benches—no dedicated utility alcove required.
• Stainless steel 316L mirror-finish inner chamber and brushed 304 stainless steel exterior ensure corrosion resistance, ease of decontamination, and long-term structural integrity in humid or chemically aggressive environments.
• Imported European circulation pump (0.25 kW) delivers stable, high-flow spray dynamics across all wash cycles, enhancing residue removal efficacy without excessive water consumption.
• Microprocessor-based control system provides precise regulation of temperature, cycle duration, detergent dosing, and rinse volume—with real-time display of operational parameters including water temperature, elapsed time, and chemical dosage.
• Three preconfigured wash programs—Standard, Intensive, and Quick—cover the majority of routine cleaning applications while allowing full user customization of temperature profiles, dwell times, and rinse sequences.
• Modular rack system accommodates a broad range of vessel geometries: 1.5 mL vials, 15–50 mL centrifuge tubes, 25–500 mL Erlenmeyer flasks, volumetric flasks, beakers, and graduated cylinders—without requiring manual repositioning during loading.
• Energy- and resource-efficient design: average water consumption < 8 L per standard cycle; total power draw optimized via staged heater activation and intelligent pump modulation.

Sample Compatibility & Compliance

The CTLW-60 is validated for cleaning and thermally disinfecting reusable glass and autoclavable polymer labware commonly used in analytical chemistry, pharmaceutical development, and academic research settings. Its cleaning performance has been verified against residual protein, sucrose, and sodium chloride challenges per ASTM D4297 and ISO 15883-1 Annex B methodologies. The unit carries CE marking (2014/30/EU EMC Directive and 2014/35/EU Low Voltage Directive), confirming conformity with essential health, safety, and electromagnetic compatibility requirements for laboratory equipment sold in the European Economic Area. While not certified to FDA 21 CFR Part 11, its audit-ready operation log (timestamped cycle records, parameter settings, and error codes) supports GLP-compliant documentation practices when integrated into validated laboratory workflows.

Software & Data Management

The CTLW-60 operates via an embedded microcontroller with non-volatile memory storing up to 100 completed cycle logs. Each log includes start/end timestamps, selected program, final rinse temperature, and any fault codes triggered during execution. No external software or network connectivity is required; however, cycle data can be manually transcribed for inclusion in electronic lab notebooks (ELNs) or quality management systems (QMS). All parameter adjustments—including temperature setpoints (30–93 °C), wash duration (5–60 min), and detergent injection volume—are password-protected to prevent unauthorized modification and support procedural consistency across multiple users.

Applications

• Preparation of HPLC/GC sample vials and autosampler trays in analytical QC labs.
• Cleaning and thermal conditioning of glassware prior to trace-metal analysis (e.g., ICP-MS, AAS) where low-background contamination is critical.
• Routine decontamination of cell culture flasks, pipette tips, and centrifuge tubes in biosafety level 1/2 research environments.
• Supporting GMP-aligned stability studies by ensuring consistent vessel cleanliness across batch testing timelines.
• Teaching lab deployment—enabling student exposure to automated cleaning principles without infrastructure upgrades.

FAQ

Does the CTLW-60 include built-in water softening or filtration?

No—the unit requires connection to a facility-supplied softened or deionized water source. Integration with point-of-use reverse osmosis or mixed-bed resin units is recommended for ultraclean applications.
Can the CTLW-60 perform sterilization (i.e., SAL 10⁻⁶)?

No—it achieves thermal disinfection (≥93 °C for ≥5 minutes), reducing microbial load by ≥log₄, but does not meet ISO 11138-defined sterilization criteria.
Is validation documentation provided with the instrument?

Yes—a Factory Acceptance Test (FAT) report, CE Declaration of Conformity, and basic IQ/OQ guidance documents are included to support site-specific qualification.
What maintenance intervals are recommended?

Daily: empty and inspect filters; weekly: clean spray arms and chamber seals; annually: verify temperature sensor calibration and pump performance against factory specifications.
Are replacement racks available for specialized vessel types?

Yes—customizable rack inserts (e.g., for microcentrifuge tubes, HPLC vial trays, or irregularly shaped flasks) are offered as optional accessories with lead times of 4–6 weeks.
