Kedao SK-HP Series Benchtop Ultrasonic Cleaner with Adjustable Power Output

Overview

The Kedao SK-HP Series Benchtop Ultrasonic Cleaner is engineered for precision cleaning of delicate laboratory components—including glassware, pipette tips, filtration membranes, microtiter plates, and precision metal parts—using high-frequency cavitation generated at 53 kHz. This frequency delivers an optimal balance between cleaning efficacy and sample integrity, minimizing surface erosion while ensuring effective removal of particulate contaminants, organic residues, and loosely adhered biofilms. Designed for routine use in QC labs, academic research facilities, and analytical service laboratories, the SK-HP series operates without integrated heating, making it suitable for thermally sensitive samples or applications where controlled ambient-temperature sonication is required. Its robust AISI 304 stainless steel tank construction ensures long-term corrosion resistance against aqueous and mild solvent-based cleaning solutions.

Key Features

• Backlit LCD interface with intuitive menu navigation for real-time monitoring and parameter adjustment
• Digitally controlled timer with extended range (1–999 minutes), supporting both short-duration degassing and prolonged cleaning protocols
• Fine-resolution power modulation: continuous 40–100% output adjustment in 1% increments, enabling method optimization across diverse sample types and soil loads
• Power failure memory function retains user-defined settings after unexpected shutdown, reducing procedural variability and reconfiguration time
• Acoustically damped hinged lid to attenuate operational noise and contain aerosol generation during sonication
• Select models equipped with a front-mounted drain valve for rapid, spill-free tank emptying—compatible with standard lab floor drains and waste collection systems
• Tank geometry optimized for uniform ultrasonic energy distribution; dimensions validated per ASTM D2603-20 (Standard Test Method for Sonic Shear Stability of Polymer Solutions)

Sample Compatibility & Compliance

The SK-HP series accommodates a broad spectrum of laboratory consumables and instrumentation components. Compatible substrates include borosilicate glass, fused silica, titanium alloys, anodized aluminum, and polypropylene-based labware. It is routinely employed in pre-analytical sample preparation workflows compliant with ISO/IEC 17025:2017 requirements for equipment verification and traceable cleaning validation. While not certified for sterile processing per ISO 13485 or FDA 21 CFR Part 820, the unit supports GLP-aligned cleaning SOPs when integrated into documented laboratory workflows. Cleaning efficacy verification may be performed using standardized test soils (e.g., bovine serum albumin films per USP ) and verified via visual inspection, gravimetric residue analysis, or surface contact angle measurement.

Software & Data Management

This benchtop ultrasonic cleaner operates as a standalone hardware platform with no embedded software stack or network connectivity. All operational parameters are configured locally via the LCD interface and stored in non-volatile memory. No data export, remote control, or audit trail functionality is provided—consistent with its classification as a Class I general-purpose laboratory utility device under IEC 61010-1. For regulated environments requiring electronic record retention, users may integrate external logging devices (e.g., USB-connected data loggers recording timer activation/deactivation events) or document settings manually within laboratory notebooks compliant with 21 CFR Part 11 Annex 11 principles.

Applications

• Pre-ICP-MS and AAS sample introduction system cleaning (nebulizers, spray chambers, torches)
• Removal of polishing compounds from optical components prior to interferometric inspection
• Decontamination of reusable electrophoresis combs and gel casting trays
• Desorption of adsorbed proteins from HPLC column frits and injector ports
• Preparation of TEM grid substrates by eliminating carbon contamination from handling
• Routine maintenance of microfluidic chip bonding fixtures and PDMS mold carriers
• Supporting ASTM E2971-16 (Standard Guide for Ultrasonic Cleaning Process Validation in Aerospace Applications) through configurable exposure duration and intensity

FAQ

Does this unit include a heater or temperature control capability?
No. The SK-HP series operates at ambient temperature only and does not incorporate heating elements or temperature feedback circuitry.
Is the ultrasonic transducer mounted on the bottom or side of the tank?
Transducers are permanently bonded to the tank bottom surface using industrial-grade epoxy adhesives, ensuring consistent energy coupling and mechanical durability over extended duty cycles.
Can this cleaner be used with flammable solvents such as acetone or ethanol?
No. Operation with volatile organic solvents is strictly prohibited due to lack of explosion-proof certification and absence of vapor containment or ignition source mitigation features.
What is the expected service life of the ultrasonic generator under continuous operation?
Rated for 10,000 hours of cumulative operation under standard laboratory conditions (25°C ambient, 60% RH, clean power supply); recommended preventive maintenance includes annual inspection of transducer bond integrity and power supply capacitor health.
Are replacement tanks or custom-sized tanks available from the manufacturer?
Kedao offers OEM replacement tanks for all SK-HP models; however, non-standard tank geometries or materials are not supported under warranty or technical documentation.
