KS-250DE Ultrasonic Cleaner with Backlit LCD Control Panel

Overview

The KS-250DE Ultrasonic Cleaner is a general-purpose, microprocessor-controlled benchtop cleaning system engineered for precision and repeatability in laboratory, academic, industrial, and quality control environments. It operates on the principle of high-frequency ultrasonic cavitation—generating microscopic implosions in aqueous or mild solvent-based cleaning media at a fixed frequency of 40 kHz. These transient cavitation events produce localized high-pressure shockwaves and intense shear forces, enabling effective removal of particulate contaminants, organic residues, biofilms, and entrapped air from complex geometries—including pipette tips, glassware, optical components, printed circuit boards, and precision mechanical parts. Designed as an integrated unit with the ultrasonic transducer bonded directly to the stainless-steel tank base, the KS-250DE eliminates external generator coupling losses and ensures optimal energy transfer efficiency. Its compact footprint and modular architecture make it suitable for ISO Class 5–7 cleanroom-adjacent workflows, routine QC sample preparation, and multi-user shared lab infrastructure.

Key Features

• Backlit 3.2-inch monochrome LCD display with full Chinese-language interface (English firmware optional upon request), providing real-time visualization of operating parameters including temperature, time, power level, and system status.
• Digitally adjustable ultrasonic power output (10–100% in 1% increments), allowing optimization for delicate substrates (e.g., MEMS devices) or heavy-duty decontamination tasks.
• Precise digital temperature control (10–80 °C ±1 °C) via PTC heating element and PID feedback loop; supports degassing, enzymatic cleaning, and low-temperature solvent-assisted processes.
• Programmable timer (1–600 minutes) with auto-shutdown and audible end-of-cycle alert; memory retains last-used settings across power cycles.
• Integrated safety interlocks: low-water detection, over-temperature cutoff, over-current protection, and open-lid shutdown—compliant with IEC 61000-6-3 EMC emission standards.
• Stainless-steel tank (304 grade, 10 L nominal volume), reinforced corner welds, and seamless interior finish for corrosion resistance and ease of validation.
• Standard accessories include removable stainless-steel mesh basket, sound-dampening lid with ergonomic handle, and automatic fill/drain port with solenoid valves for unattended operation.

Sample Compatibility & Compliance

The KS-250DE accommodates a wide range of sample types and container formats, including volumetric flasks (up to 1 L), Petri dishes, cuvettes, semiconductor wafers (≤6 inch), surgical instruments, and filtration membranes. Its cleaning efficacy has been validated per ASTM D2295 (adhesive bond strength after ultrasonic cleaning) and ISO 15797 (textile testing using ultrasonic agitation). While not certified for sterile processing under ISO 13485 or FDA 21 CFR Part 820, the unit supports GLP-compliant documentation when paired with external data loggers. All wetted surfaces meet USP Class VI biocompatibility requirements for non-invasive device cleaning. The stainless-steel construction complies with EN 10088-1 for corrosion resistance in neutral pH aqueous environments.

Software & Data Management

The KS-250DE operates via embedded firmware without external PC dependency. All operational logs—including start/stop timestamps, setpoints, fault codes (e.g., E01 = low water, E03 = overtemperature), and cumulative runtime—are stored in non-volatile memory for up to 10,000 cycles. Optional RS-232 or USB-to-serial interface (available as accessory kit) enables connection to LIMS or ELN systems for audit-trail generation. Firmware updates are performed via SD card slot (not included); version history and checksum verification ensure traceability per ALCOA+ principles. No cloud connectivity or remote access functionality is implemented—ensuring data sovereignty and alignment with institutional IT security policies.

Applications

• Routine laboratory glassware and plasticware decontamination prior to sterilization or analytical use.
• Removal of polishing compounds and metal fines from precision optics and metrology tools.
• Preparation of environmental samples (e.g., filter membranes, sediment cores) for ICP-MS or GC-MS analysis.
• Extraction of intracellular metabolites or nucleic acids from tissue homogenates under controlled thermal conditions.
• Debonding of temporary adhesives in microfabrication and PCB rework procedures.
• Accelerated aging studies requiring uniform cavitation exposure across replicate specimens.

FAQ

Is the KS-250DE compatible with flammable solvents?

No. The unit is designed exclusively for aqueous or water-miscible solutions. Use of flammable or chlorinated solvents voids warranty and violates IEC 61010-1 safety certification.
Can the ultrasonic frequency be changed to 28 kHz or 35 kHz?

No. The KS-250DE is factory-configured for 40 kHz operation only. Frequency-selectable models (e.g., KS-250DF) are available as separate SKUs.
Does the auto-fill/drain function support continuous recirculation?

No. The system performs single-cycle fill → wash → drain. Recirculating filtration requires external pump integration and is not supported out-of-the-box.
What is the expected service life of the transducers under normal usage?

Rated for ≥10,000 hours of cumulative operation at ≤80% rated power, assuming proper maintenance (e.g., regular tank descaling, avoidance of dry-running).
Is calibration certificate provided with shipment?

A factory performance verification report (including temperature accuracy and timer deviation tests) is included. NIST-traceable calibration is available as a paid add-on service.
