BEQ VGT-1990QTD 9L Benchtop Ultrasonic Cleaner

Overview

The BEQ VGT-1990QTD is a 9-liter benchtop ultrasonic cleaner engineered for precision cleaning of delicate laboratory components, analytical instrumentation parts, optical elements, semiconductor wafers, medical devices, and precision mechanical assemblies. It operates on the principle of acoustic cavitation: high-frequency sound waves (40 kHz) generate microscopic vacuum bubbles in the cleaning solution, which collapse violently upon contact with surfaces—producing localized energy sufficient to dislodge particulate contaminants, organic residues, oils, and biofilms without mechanical abrasion. This non-contact, solvent-efficient method ensures consistent cleaning performance across complex geometries—including blind holes, microchannels, and threaded surfaces—where manual or immersion methods fall short. Designed for routine use in QC laboratories, R&D facilities, and GMP-compliant manufacturing environments, the VGT-1990QTD integrates thermal regulation, programmable timing, and robust electromechanical architecture to support reproducible, traceable cleaning protocols.

Key Features

• Four independently mounted piezoelectric transducers (50 W each), delivering uniform 200 W ultrasonic power across the entire 9 L stainless steel tank for high cavitation density and spatial consistency.
• Digital timer with LED display (1–99 minute range), enabling precise control over cleaning duration to prevent overexposure or under-cleaning—critical for sensitive substrates such as quartz cuvettes or MEMS sensors.
• Adjustable heating system with ceramic heating elements, supporting temperature control from ambient to 80 °C; ideal for enhancing detergent efficacy, reducing surface tension, and accelerating removal of viscous or thermally labile residues.
• SUS304 stainless steel tank and exterior housing with brushed finish—resistant to corrosion from aqueous detergents, mild alkaline solutions, and ethanol-based rinses; compliant with ISO 15195 and ASTM D2603 requirements for laboratory equipment material compatibility.
• Integrated drain valve and ergonomic sloped base design facilitate rapid, spill-free disposal of spent cleaning solutions—reducing operator exposure and minimizing cross-contamination risk between batches.
• PCB board treated with conformal coating for moisture and chemical resistance; optimized thermal management system ensures stable operation during extended cycles (e.g., overnight decontamination protocols).

Sample Compatibility & Compliance

The VGT-1990QTD accommodates a wide range of sample types including glassware (vials, pipettes, filters), metal tools (tweezers, forceps), ceramic substrates, plastic components (PTFE, polypropylene), and coated optics—provided compatible cleaning chemistries are selected per substrate specifications. The unit meets general safety requirements per IEC 61010-1 (Electrical Equipment for Measurement, Control, and Laboratory Use) and supports documentation workflows aligned with GLP and ISO/IEC 17025 quality systems. While not certified for sterilization (i.e., does not replace autoclaving), it serves as a validated pre-sterilization cleaning step per USP and ISO 13485 Annex A guidelines for medical device reprocessing.

Software & Data Management

This model operates via embedded microcontroller firmware—no external software required. All operational parameters (time, temperature, power-on state) are retained in non-volatile memory. Though not equipped with USB/Ethernet connectivity or audit trail logging, its deterministic digital interface enables manual entry into electronic lab notebooks (ELNs) and batch records. For regulated environments requiring 21 CFR Part 11 compliance, users may integrate the unit into broader facility validation protocols by pairing it with calibrated external thermometers and stopwatch verification—standard practice for Class II ultrasonic cleaners in pharmaceutical QC labs.

Applications

• Cleaning HPLC/GC autosampler vials, syringe filters, and column frits prior to analysis.
• Removal of flux residues and solder paste from PCB assemblies during electronics prototyping.
• Preparation of TEM grids and SEM stubs to eliminate hydrocarbon contamination.
• Routine decontamination of reusable surgical instruments in research animal facilities.
• Surface preparation of electrodes, sensors, and microfluidic chips prior to functionalization or coating.
• Supporting ASTM E1722 (Standard Guide for Cleaning and Degreasing of Metals) and ISO 8502-4 (Surface cleanliness assessment) workflows.

FAQ

Is the VGT-1990QTD suitable for cleaning aluminum or soft metals?
Yes—when used with neutral or mildly alkaline aqueous solutions and controlled temperature (<60 °C), it avoids pitting or etching. Avoid acidic or chloride-containing solvents.
Can this unit be operated continuously for more than one hour?
It supports continuous operation up to 99 minutes per cycle; for extended cleaning, manual restart is required. Thermal protection circuitry prevents overheating during repeated use.
Does the unit include a degassing function?
No dedicated degas mode is provided; however, initiating ultrasonics at room temperature for 2–3 minutes before heating achieves effective air removal from the bath.
What maintenance is required for long-term reliability?
Regular tank cleaning with distilled water after solvent use, inspection of transducer mounting integrity every 6 months, and verification of temperature sensor calibration annually.
Is the SUS304 mesh basket included standard or optional?
The welded SUS304 mesh basket is available as an optional accessory; standard configuration includes a solid-bottom stainless steel basket.
