Overview
The KUDOS SK7200H is a benchtop high-frequency ultrasonic cleaner engineered for precision cleaning, degassing, emulsification, extraction, and sonochemical acceleration in academic, pharmaceutical, and industrial laboratory environments. Operating at a fixed frequency of 53 kHz, the unit leverages piezoelectric transducer technology to generate controlled cavitation within aqueous or compatible solvent media. This frequency balances penetration depth and micro-cavitation intensity—optimizing removal of sub-micron particulates, organic residues, and biofilms from delicate instrumentation (e.g., pipette tips, HPLC components, optical lenses, and microfluidic devices) without surface erosion. The 15-liter stainless steel tank (304 grade) ensures corrosion resistance, thermal stability, and long-term compliance with ISO 13485 and GLP-aligned lab infrastructure requirements. Designed for continuous operation under standard 220 V / 50 Hz AC supply, the SK7200H integrates passive heat dissipation and over-temperature protection to maintain acoustic consistency across extended duty cycles.
Key Features
- Stable 53 kHz ultrasonic output delivering reproducible cavitation energy density for consistent cleaning efficacy across batch-to-batch operations.
- 350 W nominal power output with intelligent power regulation to sustain amplitude stability despite load variation or fluid temperature drift.
- Digital timer with extended range (1–199 minutes), enabling protocol-specific dwell time programming for validated cleaning SOPs.
- 304 stainless steel tank with seamless weld construction, fully passivated per ASTM A967, resistant to chlorinated and mildly acidic solutions.
- Integrated drain valve and flexible PVC drain hose facilitate rapid, spill-free tank evacuation—critical for solvent recovery or hazardous waste handling workflows.
- Adjustable support rack included as standard, permitting vertical or horizontal sample orientation while maintaining uniform acoustic field exposure.
- Backlit LCD display with real-time timer readout and status indicators (power-on, heating active, cycle completion).
Sample Compatibility & Compliance
The SK7200H accommodates a broad range of sample geometries—including glassware (vials, cuvettes, flasks), metal components (syringe needles, surgical tools), ceramic substrates, and polymer-based microdevices—provided they are acoustically stable and chemically inert in the selected cleaning medium. It supports common aqueous detergents (e.g., Alconox®, Liquinox®), ethanol/water mixtures, and low-surface-tension solvents compatible with 304 stainless steel. The device meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and electrical safety (EN 61010-1). While not certified for sterile processing per ISO 17664 or FDA 21 CFR Part 820, it is routinely deployed in pre-sterilization cleaning steps compliant with USP and ISO 15883-1 protocols when integrated into validated cleaning workflows.
Software & Data Management
The SK7200H operates as a standalone analog-digital hybrid system with no embedded firmware or network interface. All operational parameters—including timer setting and power activation—are controlled via front-panel membrane switches with tactile feedback. No data logging, remote control, or audit trail functionality is provided; therefore, manual recordkeeping (e.g., logbook entries, timestamped SOP execution sheets) is required to satisfy GLP or GMP documentation standards. For laboratories requiring electronic records, integration with external environmental monitoring systems (via dry-contact relay outputs, optional upon request) enables basic cycle start/stop event capture aligned with 21 CFR Part 11 Annex 11 principles.
Applications
- Routine decontamination of analytical glassware prior to trace-metal analysis (ICP-MS, AAS) to minimize carryover and blank interference.
- Removal of proteinaceous residue from electrophoresis combs, gel trays, and blotting apparatus.
- Preparation of nanoparticle suspensions via ultrasonic dispersion in aqueous or organic phases.
- Accelerated solid–liquid extraction of phytochemicals or metabolites from botanical matrices under mild thermal conditions.
- In-process degassing of casting resins, adhesives, or photoresists to eliminate microvoid formation during curing.
- Supporting ASTM D2621 (cleaning verification for automotive components) and ISO 14971 risk management frameworks through repeatable process parameter control.
FAQ
Is the SK7200H suitable for cleaning delicate MEMS or semiconductor wafers?
Yes—when operated with low-power settings (achieved via duty-cycle modulation using external timers) and non-aggressive solvents such as deionized water or IPA, the 53 kHz frequency minimizes mechanical stress on fragile microstructures.
Does the unit include heating capability?
No—the SK7200H is a non-heating ultrasonic cleaner. Temperature rise during operation results solely from acoustic energy dissipation and remains typically below 5 °C over 30 minutes under standard ambient conditions.
Can the timer be bypassed for continuous operation?
No—timer activation is mandatory; the unit automatically powers down upon reaching the set duration. Continuous operation requires manual reset, supporting fail-safe adherence to safety protocols.
What maintenance is required for long-term reliability?
Monthly inspection of transducer mounting integrity, quarterly descaling of tank interior using diluted citric acid solution, and annual verification of timer accuracy against a calibrated stopwatch are recommended.
Is the drain valve compatible with standard laboratory floor drain connections?
Yes—the 1/2-inch BSP threaded outlet accepts standard laboratory-grade PVC or silicone drain tubing (ID 12 mm), allowing direct connection to sink traps or waste solvent collection vessels.
