Shengyan SCQ-250B1 5L Benchtop Ultrasonic Cleaner

Overview

The Shengyan SCQ-250B1 is a benchtop ultrasonic cleaner engineered for routine laboratory cleaning, degreasing, and particle removal from precision components, glassware, surgical instruments, and small-volume sample containers. It operates on the principle of high-frequency acoustic cavitation—where ultrasonic energy (25, 40, or 60 kHz, factory-set per unit) generates microscopic vacuum bubbles in aqueous or mild solvent-based cleaning solutions. Upon collapse, these bubbles release localized energy sufficient to dislodge contaminants without mechanical abrasion or thermal stress. The SCQ-250B1 delivers consistent 180 W of ultrasonic power across its 5 L stainless steel tank (300 × 150 × 100 mm internal dimensions), making it suitable for QC labs, academic research facilities, and small-scale manufacturing environments where reproducible, non-destructive cleaning is required.

Key Features

• Benchtop design with compact footprint (approx. 340 × 200 × 270 mm external dimensions) optimized for limited lab space
• Single-frequency operation (25 kHz, 40 kHz, or 60 kHz)—selected at time of order; each frequency offers distinct trade-offs: 25 kHz for heavy particulate removal, 40 kHz for general-purpose cleaning, and 60 kHz for delicate substrates requiring finer cavitation intensity
• Stainless steel 304 tank with seamless construction for corrosion resistance and long-term chemical compatibility with common lab detergents and isopropyl alcohol solutions
• Digital timer with precise 1-minute resolution, programmable from 1 to 600 minutes (10 hours), enabling unattended operation and protocol standardization
• Integrated sound-dampening lid reduces ambient noise by up to 15 dB(A), improving workplace ergonomics and compliance with ISO 14040-based noise management guidelines in shared lab environments
• Included stainless steel mesh basket (120 µm aperture) ensures uniform part suspension and prevents direct contact between samples and tank bottom, minimizing shadowing effects and enhancing cleaning uniformity
• No built-in heater or temperature regulation—designed for ambient-temperature operation to maintain stability of thermally sensitive samples and avoid accelerated solvent evaporation

Sample Compatibility & Compliance

The SCQ-250B1 accommodates a wide range of laboratory items including pipette tips, microcentrifuge tubes, crucibles, watch glasses, metal calibration weights, and printed circuit board assemblies. Its fixed-frequency, fixed-power architecture meets baseline requirements for ASTM D2603 (Standard Test Method for Sonic Shear Stability of Lubricating Oils) and ISO 13076 (Ultrasonic cleaning equipment — Vocabulary and performance testing). While not certified to FDA 21 CFR Part 11 or EU Annex 11, the device supports GLP-compliant workflows when integrated into documented cleaning SOPs—including operator logs, solution change records, and timer verification protocols. Units are CE-marked per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), with RoHS 3-compliant materials used throughout the chassis and transducer assembly.

Software & Data Management

This model operates via a dedicated digital control panel with LED display and tactile push-button interface—no software installation, driver dependencies, or network connectivity required. All operational parameters (timer setting, power-on confirmation, and cycle completion signal) are locally recorded via visual indicators only. For laboratories implementing electronic recordkeeping, manual entry of cleaning parameters into LIMS or ELN systems is supported through standardized fields: “Device ID”, “Frequency (kHz)”, “Duration (min)”, “Solution Type”, and “Operator Initials”. Audit trail integrity is maintained via timestamped logbooks aligned with ISO/IEC 17025:2017 Clause 7.5.2 (Control of records).

Applications

• Cleaning of HPLC vials, GC autosampler inserts, and ICP-MS sample cones prior to trace-metal analysis
• Removal of organic residues from optical lenses, microscope slides, and spectrophotometer cuvettes
• Preparation of metal coupons for ASTM G1-03 corrosion testing
• Decontamination of reusable surgical tools in veterinary and teaching labs (when used with EPA-approved disinfectant solutions)
• Supporting ISO 14644-1 cleanroom component maintenance workflows, particularly for Class 7 and Class 8 environments
• Removing polishing compounds from semiconductor wafers during R&D prototyping stages

FAQ

Is the ultrasonic frequency user-selectable after purchase?
No. Frequency (25 kHz, 40 kHz, or 60 kHz) is hardwired at the factory and cannot be changed in the field.
Can this unit be used with heated cleaning solutions?
Yes—but only if pre-heated externally. The SCQ-250B1 lacks an integrated heater; using hot solutions above 60 °C may accelerate gasket degradation and reduce transducer lifespan.
Does the unit include a drain valve for solution disposal?
No. Solution must be manually decanted or aspirated using a siphon or pump.
What is the expected service life of the piezoelectric transducers?
Under normal use (≤4 hours/day, deionized water or neutral pH detergent), transducers typically exceed 5,000 operating hours before measurable output decay (>10% reduction in cavitation intensity).
Is the stainless steel basket compatible with ultrasonic degreasing solvents?
Yes—the 304 stainless steel basket resists corrosion in hydrocarbon-based solvents (e.g., n-hexane, mineral spirits) and aqueous alkaline cleaners (pH 9–11), but not strong oxidizers such as nitric acid or bleach solutions.
