Grant XUB Digital Ultrasonic Cleaner

Overview

The Grant XUB Digital Ultrasonic Cleaner is an engineered solution for precision cleaning, degassing, and sample preparation in regulated laboratory environments. Based on piezoelectric transducer technology operating within a stable 32–38 kHz frequency band, the XUB series utilizes controlled cavitation physics to generate micro-scale implosions in aqueous or compatible solvent media. These implosions produce localized high-pressure and high-temperature transient zones—enabling mechanical removal of particulate contaminants, biofilms, and organic residues from surfaces with complex geometries. Unlike fixed-frequency cleaners, the XUB incorporates LEAP (Low-Energy Acoustic Pulse) frequency modulation—a dynamic sweep across the operational bandwidth that disrupts standing wave formation and eliminates acoustic dead zones. This ensures uniform energy distribution throughout the bath volume, critical for reproducible results in applications ranging from analytical instrument component cleaning to cell lysis and nanoparticle dispersion.

Key Features

• LEAP frequency modulation (32–38 kHz sweep) for homogeneous ultrasonic field distribution and minimized nodal interference
• Digital PID temperature control with ±0.5°C stability across ambient +5°C to 70°C range
• Multi-parameter programmable interface: independent control of ultrasonic duty cycle, heating setpoint, total process duration (0–99 min), and degas mode
• Integrated SD card slot with timestamped, tamper-resistant logging compliant with GLP audit requirements (data includes time, temperature, power status, and cycle completion flag)
• Backlit alphanumeric LCD display with intuitive menu-driven navigation and real-time parameter feedback
• Stainless steel tank construction (AISI 316 grade) with integrated ABS lid, ergonomic lift basket, and factory-fitted BSP drain valve (3/8″ or 1/2″ depending on model)
• Five scalable models (XUB5 to XUB25) covering working volumes from 4.5 L to 25 L, each validated for consistent acoustic output per unit volume
• Heating elements with thermal cut-off protection and independent overtemperature monitoring circuitry

Sample Compatibility & Compliance

The XUB series is designed for compatibility with standard laboratory solvents including deionized water, aqueous detergents, ethanol, isopropanol, and low-viscosity hydrocarbon blends. Its non-aggressive, non-thermal cleaning mechanism preserves delicate substrates such as optical lenses, microfluidic chips, HPLC columns, surgical instruments, and MEMS devices. All models meet IEC 61010-1:2010 safety standards for electrical equipment used in laboratory environments. The digital control architecture supports traceability requirements under ISO/IEC 17025, USP , and FDA 21 CFR Part 11 when paired with validated SD card data handling procedures. Optional calibration certificates (NIST-traceable temperature and timing verification) are available upon request.

Software & Data Management

No external software installation is required—the XUB operates as a standalone instrument with embedded firmware supporting full-cycle data capture directly to FAT32-formatted SD cards. Each logged entry contains date/time stamp, target and actual temperature profile (sampled every 10 seconds), ultrasonic activation state, elapsed time, and final status code. Data files are CSV-exportable for integration into LIMS or electronic lab notebook (ELN) systems. Audit trail functionality records all user-initiated configuration changes—including password-protected administrator access levels for method locking and calibration override prevention—ensuring compliance with GxP documentation standards.

Applications

• Cleaning of glassware, pipette tips, filtration membranes, and chromatography hardware prior to analysis
• Removal of residual solder flux, oxides, and polishing compounds from precision engineering components
• Preparation of nanoparticle suspensions and emulsions via controlled sonication-assisted dispersion
• Cell disruption and protein extraction in molecular biology workflows
• Ultrasonic degassing of mobile phases, solvents, and resin slurries to prevent bubble-induced flow instability
• Surface decontamination of reusable medical devices in ISO 13485-certified facilities
• Accelerated aging studies requiring repeatable thermal–acoustic stress exposure

FAQ

What is the purpose of LEAP frequency modulation?

LEAP dynamically shifts the operating frequency to suppress standing wave patterns, ensuring consistent cavitation intensity across the entire tank volume—particularly important for irregularly shaped or stacked samples.
Can the XUB be used for sterilization?

No. The XUB is not a sterilizer; it provides cleaning and disinfection-level bioburden reduction. Sterilization requires validated steam, dry heat, or ethylene oxide processes per ISO 17665 or ISO 11135.
Is the SD card data exportable for regulatory review?

Yes. Logged files are plain-text CSV format, readable in Excel or statistical analysis platforms, and support full audit trail reconstruction per ALCOA+ principles.
What maintenance is required?

Routine inspection of tank integrity, drain valve sealing, and transducer coupling gel condition (if service-accessible). Annual verification of temperature accuracy and timer calibration is recommended.
Are custom tank dimensions or materials available?

Standard configurations only. Custom fabrication is not offered; however, five pre-engineered models cover >90% of institutional and industrial use cases.
