Langbo LB-600 Industrial Ultrasonic Cleaning Tank

Overview

The Langbo LB-600 Industrial Ultrasonic Cleaning Tank is a high-capacity, multi-frequency ultrasonic cleaning system engineered for demanding laboratory, R&D, and pilot-scale manufacturing environments. It operates on the principle of acoustic cavitation—where high-frequency sound waves generate microscopic vacuum bubbles in the cleaning solution that collapse with localized energy release, effectively dislodging particulate contaminants, organic residues, and thin oxide layers from submerged surfaces. Unlike benchtop units, the LB-600 is designed as a floor-standing, heavy-duty cleaning station with a 600-liter working volume, supporting large-format components, glassware batches, metal tooling, and semiconductor wafers. Its tri-frequency capability (25 kHz, 40 kHz, and 80 kHz) enables process optimization across diverse material classes: lower frequencies deliver higher cavitation intensity for robust mechanical cleaning of machined parts; mid-range frequencies balance penetration and gentleness for delicate optics or ceramic substrates; and higher frequencies provide finer resolution for sub-micron particle removal in precision optics or medical device reprocessing.

Key Features

• Triple-frequency ultrasonic generation (25 kHz / 40 kHz / 80 kHz) with independent frequency selection and real-time power modulation
• 6 kW total ultrasonic output distributed across multiple transducer arrays mounted on tank bottom and side walls for uniform energy distribution
• Adjustable ultrasonic power from 40% to 100% in 5% increments, enabling reproducible cleaning validation protocols
• Precise digital temperature control (ambient to 100 °C) with ±1 °C accuracy and PID-based heating regulation
• Extended programmable timer (0–59 h 59 min) supporting multi-stage cleaning cycles with automatic heat-up, sonication, and rinse sequencing
• Sound-dampening insulated lid with safety interlock, reducing ambient noise to ≤65 dB(A) at 1 m distance
• Integrated fill-and-drain ports with quick-connect fittings compatible with standard 1″ NPT plumbing infrastructure
• Dual-grade stainless steel construction: electropolished SUS316 interior (resistant to chlorinated and acidic aqueous solutions) and structural SUS304 outer housing
• Front-panel touchscreen interface with password-protected parameter locking and event logging (timestamped start/stop, temperature setpoint, power level)

Sample Compatibility & Compliance

The LB-600 accommodates a wide range of sample geometries and materials—including but not limited to stainless steel fixtures, aluminum housings, borosilicate glassware, quartz cuvettes, silicon wafers, titanium implants, and polymer-based microfluidic devices. Its large internal dimensions (750 × 740 × 550 mm) allow immersion of full-size ISO Class 5 cleanroom trays or stacked industrial baskets. The system supports cleaning processes compliant with ASTM D2603 (Standard Test Method for Sonic Shear Stability of Lubricants), ISO 13406-2 (for optical component cleanliness verification), and USP particulate matter testing preparation workflows. When operated with validated detergents and documented cycle parameters, it meets GLP documentation requirements for cleaning validation in regulated QC laboratories.

Software & Data Management

The LB-600’s embedded controller records all operational events—including cycle ID, date/time stamp, temperature profile, ultrasonic power setting, frequency selection, and total elapsed time—in non-volatile memory. Data export is supported via USB 2.0 port (CSV format) for integration into LIMS or electronic batch record systems. Optional RS-485 Modbus RTU interface enables remote monitoring and control from central SCADA platforms. Audit trail functionality complies with FDA 21 CFR Part 11 requirements when paired with user authentication and electronic signature modules (available as add-on firmware package).

Applications

• Pre-sterilization cleaning of surgical instruments and reusable medical devices prior to autoclaving
• Removal of photoresist residues and etch byproducts from semiconductor wafers and mask blanks
• Decontamination of analytical glassware (volumetric flasks, pipettes, HPLC columns) in pharmaceutical QC labs
• Surface preparation of aerospace alloys prior to non-destructive testing (NDT) or coating adhesion assessment
• Cleaning of precision optical components—including laser lenses, interferometer mirrors, and fiber optic connectors
• Batch cleaning of 3D-printed metal parts to eliminate support structure residue and powder entrapment
• Environmental sample preparation for trace metal analysis (e.g., EPA Method 1669 compliance)

FAQ

What cleaning solutions are compatible with the LB-600?
Aqueous alkaline, neutral, and mildly acidic detergents are recommended. Avoid halogenated solvents and strong oxidizers (e.g., concentrated nitric acid) unless using optional corrosion-resistant upgrades.
Can the LB-600 be integrated into an automated cleaning line?
Yes—via its Modbus RTU interface and dry-contact I/O terminals for external start/stop signaling and status feedback.
Is validation support documentation available?
Langbo provides IQ/OQ protocol templates, transducer performance verification checklists, and temperature uniformity mapping guidance upon request.
Does the system meet CE or UL safety standards?
The LB-600 conforms to IEC 61000-6-3 (EMC) and IEC 61000-6-4; CE marking is applied for EU export configurations. UL listing is available under custom certification path.
What maintenance is required for long-term reliability?
Quarterly inspection of transducer mounting integrity, annual calibration of temperature sensor and timer accuracy, and biannual replacement of ultrasonic generator cooling fans.
