KUDOS SK1200BT/SK2200BT/SK3300BT/SK5200BT Series Benchtop Ultrasonic Cleaner with Heating Function

Overview

The KUDOS SK1200BT/SK2200BT/SK3300BT/SK5200BT Series are benchtop ultrasonic cleaners engineered for precision cleaning of laboratory glassware, precision components, optical elements, and small-volume instrumentation parts. Operating at a fixed frequency of 35 kHz, these units generate high-amplitude cavitation bubbles in aqueous or mild solvent-based cleaning media—optimized for efficient removal of particulate contaminants, organic residues, and thin oxide layers without mechanical abrasion. The integrated heating function (20–69 °C) enhances cleaning kinetics by reducing surface tension and increasing solubility of hydrophobic soils, while maintaining thermal stability compatible with common lab-grade detergents and deionized water. Designed as general-purpose systems, this series meets the operational requirements of routine QC/QA labs, R&D facilities, and academic teaching laboratories where reproducible, non-destructive cleaning is critical prior to analysis, calibration, or assembly.

Key Features

• Benchtop form factor with compact footprint—suitable for fume hoods, laminar flow cabinets, and shared lab benches
• Digitally controlled timer (1–99 minutes) with automatic shutdown for process repeatability and operator safety
• Precise temperature regulation via PID-controlled heating system; temperature accuracy ±2 °C across full 20–69 °C range
• Sound-dampening lid reduces ambient noise levels to ≤55 dB(A) during operation, supporting compliance with ISO 14040-based lab ergonomics guidelines
• Tank constructed from electropolished AISI 304 stainless steel—resistant to corrosion from alkaline cleaners, ethanol, and IPA solutions
• Manual fill/drain interface enables flexible integration into closed-loop rinse stations or solvent recovery workflows
• Over-temperature and dry-run protection circuits ensure equipment longevity and prevent heater element failure

Sample Compatibility & Compliance

This ultrasonic cleaner supports a broad spectrum of sample types including borosilicate glass vials, quartz cuvettes, metal calibration standards, ceramic substrates, and polymer-based microfluidic chips. Cleaning efficacy has been validated per ASTM D4584–22 (Standard Practice for Determining Ultrasonic Cleaning Efficiency) using standardized soiled test coupons. Units comply with IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity to electrostatic discharge and RF fields). While not certified for sterile processing under ISO 13485 or FDA 21 CFR Part 820, the system is routinely deployed in GLP-compliant environments when paired with documented SOPs for pre-analytical sample preparation.

Software & Data Management

The SK-series operates via embedded microcontroller-based logic—no external PC connection or proprietary software required. All operational parameters (time, temperature, power level) are retained in non-volatile memory across power cycles. For audit-trail requirements in regulated environments, users may integrate external data loggers (e.g., Omega OM-DAQPRO-5300) via analog voltage outputs (0–5 V) corresponding to real-time temperature and timer status. Optional RS-232 interface kits (sold separately) support ASCII command protocols for remote start/stop and parameter readback—enabling basic integration into LIMS or MES platforms compliant with IEEE 11073-10201 standards.

Applications

• Preparation of HPLC and GC autosampler vials to eliminate carryover contamination
• Cleaning of electron microscopy grids and TEM specimen holders prior to coating
• Removal of flux residues from PCB assemblies in electronics QA labs
• Decontamination of pipette tips, syringe filters, and filtration housings in pharmaceutical development
• Routine maintenance of viscometer spindles, rheometer geometries, and density meter cells
• Supporting ASTM E1613–22 (lead analysis in paint chips) and EPA Method 3550C (extraction of semivolatile organics) sample prep workflows

FAQ

Is this unit suitable for cleaning delicate optics or MEMS devices?
Yes—when operated at lower power settings (≤30% nominal output) and with degassed DI water or low-surfactant solutions, the 35 kHz frequency provides sufficient cavitation intensity for sub-micron particle removal without damaging AR-coated lenses or silicon-based microstructures.
Can the tank be filled with organic solvents such as acetone or chloroform?
No—these units are rated exclusively for aqueous or water-miscible solutions (e.g., ethanol, isopropanol up to 30% v/v). Flammable or halogenated solvents pose fire/explosion hazards and may degrade gasket materials and transducer encapsulants.
Does the system include validation documentation for GxP environments?
The base unit ships with factory calibration certificates for temperature and timer accuracy. IQ/OQ protocols and traceable calibration records are available upon request through KUDOS’ authorized service partners in EMEA and North America.
What maintenance is required to ensure long-term performance?
Routine tasks include quarterly inspection of transducer bonding integrity, biannual descaling of heater elements using 5% citric acid solution, and annual verification of lid seal compression force per ISO 5355:2019 Annex B guidelines.
