Overview
The QCD Series Digital Ultrasonic Cleaner is an engineered solution for precision laboratory cleaning tasks requiring consistent cavitation intensity and operational reliability. Unlike conventional fixed-frequency ultrasonic cleaners operating at a single resonant frequency (typically 40 kHz), the QCD Series employs pulse-modulated ultrasonic energy delivery. This modulation ensures that each acoustic pulse exceeds the cavitation threshold—enabling sustained, controlled nucleation and collapse of microbubbles in the cleaning medium. The result is enhanced mechanical energy transfer to contaminant interfaces without excessive thermal loading or probe erosion, making it especially suitable for delicate substrates such as optical components, semiconductor wafers, microfluidic devices, and analytical sample holders.
Built with industrial-grade stainless-steel tanks (304 grade), digital microprocessor control, and electromagnetic shielding for stable operation in shared lab environments, the QCD6150 model serves as the mid-capacity variant in the series—optimized for routine QC/QA workflows, preparatory sample handling prior to spectroscopy or chromatography, and pre-sterilization cleaning of reusable glassware and metal tools.
Key Features
- Pulse-modulated ultrasonic drive circuitry—maintains peak acoustic pressure above cavitation threshold across full power range (40–100%)
- Digital LED interface with real-time display of operating time, power level, and status indicators
- Stainless-steel tank (304 grade) with rounded internal corners to minimize dead zones and facilitate complete drainage
- Adjustable timer (1–30 minutes) with automatic shutdown and audible alert
- Robust transformer-isolated power supply for EMI suppression and long-term stability under continuous duty cycles
- Front-panel membrane keypad with tactile feedback and sealed construction for chemical resistance
- Compliant with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity to electrostatic discharge and RF fields)
Sample Compatibility & Compliance
The QCD6150 accommodates standard laboratory vessels including beakers (up to 500 mL), Petri dishes, pipette tips racks, syringe filters, and small-volume reaction vials. Its 6 L tank volume supports batch processing of up to 12 standard 25 mL volumetric flasks or 8 borosilicate glass cuvettes simultaneously. The unit is compatible with aqueous detergents, ethanol/water mixtures, and low-surface-tension solvents commonly used in analytical labs—provided solvent flash points exceed 60 °C and vapor concentrations remain below occupational exposure limits (OSHA PEL/ACGIH TLV). While not certified for medical device reprocessing per ISO 15883 or EN 285, the cleaner meets general-purpose cleaning requirements aligned with ASTM D2601 (Standard Practice for Cleaning Laboratory Glassware) and CLSI GP26-A4 (Guideline for Cleaning and Disinfection of Laboratory Equipment).
Software & Data Management
The QCD6150 operates via embedded firmware without external PC dependency. All operational parameters—including duration, power percentage, and cycle count—are stored in non-volatile memory and retained after power interruption. Though no USB or Ethernet interface is provided, the unit supports GLP-compliant documentation through manual logbook entry: each cleaning cycle can be recorded with timestamp, operator ID, load description, and detergent lot number. For labs implementing electronic lab notebooks (ELN), integration is achievable via optional RS-232 serial output (available on request with custom firmware version)—enabling automated logging of start/stop events and fault codes into validated data systems compliant with FDA 21 CFR Part 11 audit trail requirements.
Applications
- Pretreatment of HPLC vials, GC autosampler inserts, and ICP-MS sample cones to eliminate trace metal carryover
- Removal of organic residues from quartz NMR tubes and IR transmission cells
- Cleaning of MEMS sensors, photomasks, and lithography reticles prior to metrology inspection
- Decontamination of reusable electrophoresis combs, gel trays, and blotting membranes
- Pre-analytical preparation of environmental filter papers and air sampling cassettes
- Supporting ISO/IEC 17025-accredited laboratories in maintaining documented cleaning validation protocols
FAQ
Is the QCD6150 suitable for cleaning aluminum or soft metals?
Yes—when used with neutral pH aqueous detergents and limited exposure time (≤10 min), it poses minimal risk of pitting or etching. Avoid chloride-containing solutions.
Can I use acetone or chlorinated solvents in this unit?
No. The QCD6150 is designed exclusively for water-based or alcohol-based cleaning media. Flammable or halogenated solvents require explosion-proof ultrasonic systems certified to ATEX/IECEx standards.
Does the unit include a degassing function?
No dedicated degas mode is implemented; however, the pulse modulation inherently reduces dissolved gas saturation during initial fill, minimizing bubble interference during critical cleaning phases.
What maintenance is required for long-term reliability?
Annual inspection of transducer bonding integrity and tank weld seams is recommended. Replace the cleaning solution after every 5–10 cycles depending on soil load; never operate the unit dry.
Is calibration or traceable verification available?
While no factory calibration certificate is supplied, third-party acoustic intensity mapping (per ASTM E1000) and cavitation distribution profiling can be performed using calibrated hydrophones—supporting internal quality audits.
