Overview
The Supmile KQ-100E is a compact, benchtop ultrasonic cleaner engineered for routine cleaning, degassing, and particle removal in academic laboratories, quality control environments, and small-scale industrial R&D settings. It operates on the principle of ultrasonic cavitation—where high-frequency sound waves (40 kHz) generate microscopic vacuum bubbles in the cleaning solution; their rapid collapse produces localized shockwaves and microstreaming that effectively dislodge contaminants from surfaces without mechanical abrasion. Designed for reliability and ease of use, the KQ-100E features a fully stainless steel (AISI 304) tank and housing, ensuring corrosion resistance and long-term compatibility with aqueous and mild solvent-based cleaning media. Its 4 L tank volume supports standard laboratory glassware—including beakers, flasks, pipette tips, and small metal components—while maintaining uniform energy distribution across the bath.
Key Features
- Robust 304 stainless steel construction for chemical resistance and structural integrity
- Dedicated 40 kHz transducer system delivering consistent cavitation intensity at 100 W total ultrasonic power output
- Adjustable analog timer (1–20 minutes) enabling precise process repeatability for standardized cleaning protocols
- Integrated heating function (400 W) with temperature control from ambient up to 80 °C, supporting enhanced cleaning efficiency for waxy or viscous residues
- Sound-dampening lid reduces operational noise to ≤55 dB(A) at 1 m distance, improving lab ergonomics
- Manual fill-and-drain valve for controlled fluid handling; compatible with deionized water, ethanol, isopropanol, and low-concentration alkaline or neutral detergents
- Simple mechanical control interface—no software dependencies—ensuring operational stability and minimal maintenance requirements
Sample Compatibility & Compliance
The KQ-100E accommodates a broad range of sample types including glass, ceramic, stainless steel, aluminum, and certain polymers (e.g., PTFE, polypropylene), provided they are not ultrasonically fragile (e.g., thin-walled capillaries or delicate optical components). The unit complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity). While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its analog control architecture and traceable operating parameters (time, temperature, cycle count via manual log) support GLP-aligned documentation when integrated into validated cleaning SOPs. Users performing critical cleaning—such as for HPLC vials or surgical instruments—should validate cleaning efficacy per ASTM F3127 or ISO 15883-5 using appropriate test soils and recovery assays.
Software & Data Management
The KQ-100E does not incorporate digital controllers, embedded firmware, or data export capabilities. All operational parameters are set manually via front-panel dials, eliminating cybersecurity risks associated with networked devices and simplifying qualification under regulated environments where audit trails are managed externally. For labs requiring electronic recordkeeping, time/temperature logs can be captured via external USB data loggers or integrated into LIMS workflows using operator-entered batch records. No password protection, user roles, or electronic signatures are implemented—consistent with its design as a general-purpose utility instrument rather than a GMP-critical device.
Applications
- Routine cleaning of analytical glassware prior to spectroscopic or chromatographic analysis
- Removal of polishing compounds and particulate debris from precision optics and metrology tools
- Preparation of substrates for SEM, TEM, or AFM sample mounting
- Extraction support for solid-phase microextraction (SPME) and leaching studies
- Disassembly aid for electronics cleaning (e.g., PCBs, connectors) using non-aqueous solvents
- Supporting ASTM D2621, ISO 10545-14, and USP cleaning validation protocols when paired with residue detection methods
FAQ
Is the KQ-100E suitable for cleaning delicate MEMS devices or semiconductor wafers?
No—it lacks frequency sweeping, degas mode, or pulsed operation required for ultra-sensitive substrates. Use only with robust components and verify compatibility via preliminary testing.
Can the unit operate continuously beyond 20 minutes?
The timer is mechanically limited to 20 minutes per cycle; extended operation requires manual reset. Continuous duty is not recommended—allow ≥10 min cooldown between cycles to preserve transducer longevity.
Does the heater maintain ±1 °C temperature stability?
Temperature control is proportional (not PID-regulated); typical stability is ±3 °C over the full range, adequate for general cleaning but not for thermally sensitive processes.
What cleaning solutions are compatible?
Aqueous alkaline, neutral, or mildly acidic detergents; alcohols (ethanol, IPA); and deionized water. Avoid halogenated solvents, strong acids (e.g., HNO₃), or solutions exceeding 80 °C.
Is the tank drain valve self-sealing and leak-proof?
The manual drain valve uses a brass compression fitting with EPDM O-ring; periodic inspection and replacement are advised after 12 months of regular use.
