Hanon BS280CD Laboratory Bottle Washer

Overview

The Hanon BS280CD Laboratory Bottle Washer is a fully automated, high-capacity cleaning system engineered for reproducible, residue-free decontamination of glassware, volumetric flasks, pipettes, reaction vessels, and other labware commonly used in analytical, pharmaceutical, and quality control laboratories. It operates on the principle of controlled low-pressure, high-frequency recirculating spray—enabled by variable-frequency drive (VFD) technology—to deliver consistent mechanical action without compromising vessel integrity. Unlike high-pressure jet systems that risk thermal or mechanical stress on delicate or calibrated glassware, the BS280CD employs a soft-start pump sequence followed by sustained low-pressure pulsation (typically 0.1–0.3 bar), ensuring thorough soil removal while preserving calibration accuracy and surface finish. Its 180 L chamber accommodates standard rack configurations—including ISO-compliant 300 mm and 400 mm height baskets—and supports batch processing under validated temperature profiles up to 93 °C, meeting critical thermal disinfection thresholds defined in ISO 15883-1 for washer-disinfectors.

Key Features

• Variable-frequency drive (VFD) pump control enabling soft-start operation and precise regulation of spray pressure and frequency
• Stainless steel 316L wash chamber with seamless welded construction and electropolished interior for corrosion resistance and cleanability
• Dual-zone heating system with 6 kW total power output, supporting rapid ramp-up to 93 °C and stable thermal hold during extended cycles
• Programmable multi-stage cycle architecture: pre-rinse, detergent wash, intermediate rinse, final rinse, thermal disinfection, and hot-air drying (optional)
• Integrated temperature and conductivity monitoring at inlet, sump, and drain points for real-time process verification
• Touchscreen HMI with password-protected user levels (Operator, Technician, Administrator) and audit-trail-enabled event logging

Sample Compatibility & Compliance

The BS280CD accommodates a broad range of laboratory containers, including but not limited to borosilicate glass bottles (up to 2 L), volumetric flasks (Class A, B), graduated cylinders, NMR tubes, chromatography vials, and plasticware rated for repeated thermal cycling (e.g., polypropylene, PTFE-lined caps). It complies with core design and performance requirements outlined in ISO 15883-1:2018 (washer-disinfectors for thermolabile and heat-stable medical devices), and its operational parameters align with laboratory best practices referenced in USP Analytical Instrument Qualification and ASTM E2889-13 Standard Guide for Validation of Automated Cleaning Equipment. While not classified as a medical device washer, its thermal disinfection capability at ≥90 °C for ≥1 minute satisfies AAMI ST34 Annex C criteria for non-critical surface decontamination in GLP/GMP environments.

Software & Data Management

The embedded control software supports full-cycle traceability through time-stamped digital records of temperature profiles, pump runtime, detergent dosage events, and door interlock status. All data are stored locally on an industrial-grade SD card with 1-year retention capacity and exportable via USB 2.0 in CSV format. Optional Ethernet connectivity enables integration with laboratory information management systems (LIMS) or centralized monitoring platforms. Audit trail functionality meets FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with user authentication, electronic signature prompts, and immutable log archiving—making it suitable for regulated QC/QA workflows in pharmaceutical and contract research organizations.

Applications

• Routine cleaning of HPLC vials, autosampler trays, and sample prep glassware prior to trace-level analysis
• Decontamination of reusable bioreactor components and fermentation vessels between batches
• Removal of proteinaceous, lipid, or polymer residues from analytical instrumentation sample paths
• Preparation of certified reference material containers in metrology labs requiring particulate-free surfaces
• Supporting ISO/IEC 17025 accredited testing laboratories in maintaining documented cleaning validation protocols

FAQ

What types of detergents are compatible with the BS280CD?

Acidic and alkaline liquid detergents formulated for laboratory washer-disinfectors—such as Alconox® Liquinox®, Tergazyme®, or Deconex® series—are fully compatible. Avoid powdered or chlorine-based formulations unless explicitly approved by the detergent manufacturer for recirculating systems.
Can the BS280CD be validated for GMP use?

Yes—the unit supports IQ/OQ/PQ documentation packages, including temperature mapping, detergent concentration verification, and residue recovery studies. Its programmable logic controller (PLC) architecture and data logging features facilitate compliance with EU Annex 15 and FDA guidance on equipment qualification.
Is hot-air drying integrated into the standard configuration?

Hot-air drying is available as an optional module (BS280CD-Dry); the base model terminates with a final hot rinse and passive drip-dry phase.
Does the system support remote monitoring or alarm notification?

Remote monitoring is enabled via optional Ethernet interface and Modbus TCP protocol. Email/SMS alerts require external SCADA or building management system integration.
What maintenance intervals are recommended?

Daily: filter inspection and sump cleaning; Quarterly: spray arm alignment check and pump seal inspection; Annually: full calibration of temperature sensors and conductivity probe verification per ISO/IEC 17025 Clause 6.5.
