Branson CPX5800H-C Benchtop Ultrasonic Cleaner

Overview

The Branson CPX5800H-C is a high-precision benchtop ultrasonic cleaner engineered for reproducible, controlled cleaning and sample preparation in regulated laboratory environments. It operates on the principle of cavitation—generating microscopic vacuum bubbles in liquid media via high-frequency (40 kHz) acoustic energy transmitted through a Langevin-type piezoelectric transducer assembly. These collapsing bubbles produce localized shockwaves and microstreaming that effectively dislodge particulate contaminants, organic residues, and biofilms from delicate instrumentation, glassware, surgical tools, and microcomponents without mechanical abrasion. Designed for compliance-critical workflows, the CPX5800H-C integrates digital control architecture with real-time power tracking, thermal stability, and programmable operation—making it suitable for applications ranging from routine labware decontamination to pre-analytical sample conditioning in QC/QA, pharmaceutical development, and materials science laboratories.

Key Features

• Digital microprocessor-controlled interface with intuitive menu navigation and backlight LCD display
• Automatic ultrasonic power tracking ensures consistent energy delivery across varying load conditions and fluid levels
• Two-stage power selection (High/Low) enables optimization for sensitive substrates or heavily soiled samples
• Degassing mode with up to 99-minute programmable duration supports solvent conditioning prior to analytical procedures
• Precise temperature calibration function allows field verification and adjustment against external reference thermometers
• Integrated audible alarm system alerts users to anomalies including overtemperature, dry-run, or timer completion
• Corrosion-resistant construction: 304 stainless steel tank interior and polypropylene (PP) housing compliant with common laboratory solvents and mild acids
• Langevin-type transducer assembly with ceramic-metal composite elements, bonded directly to the tank bottom for enhanced durability and acoustic coupling efficiency
• Vertically oriented internal PCB layout minimizes moisture ingress risk and improves long-term reliability in humid environments
• Ergonomic control panel positioned above the tank rim prevents liquid intrusion during operation
• Optimized water-level indicator ensures maximum cavitation efficiency at recommended fill volume
• Sound-dampening hinged lid doubles as a drip tray and incorporates a quick-release drain valve for rapid fluid evacuation

Sample Compatibility & Compliance

The CPX5800H-C accommodates a wide range of sample geometries—including beakers, flasks, Petri dishes, pipette tips, microcentrifuge tubes, and precision components—within its 292 × 241 × 152 mm tank dimensions. Its non-aggressive cleaning mechanism preserves surface integrity of optics, MEMS devices, and coated substrates. The unit conforms to electromagnetic compatibility and safety standards per FCC Part 15, CSA C22.2 No. 61010-1, UL 61010-1, and EN 61000-6-3/6-4. Full TÜV Rheinland certification confirms compliance with IEC 61010-1 for electrical safety in laboratory equipment. While not inherently validated for GxP environments, its programmable parameters, audit-ready timer logs, and stable thermal performance support integration into GLP/GMP-aligned SOPs when paired with documented calibration and maintenance protocols.

Software & Data Management

This model features embedded firmware—not PC-dependent software—with persistent parameter memory for up to five user-defined programs. All operational data—including elapsed time, set temperature, and active power level—are displayed in real time and retained across power cycles. Though no direct USB or Ethernet connectivity is provided, the digital timer and temperature readout enable traceable manual logging compatible with FDA 21 CFR Part 11 requirements when implemented within a validated documentation workflow. Optional accessories—including perforated baskets, solid-bottom trays, and custom rack inserts—extend adaptability across ISO/IEC 17025-compliant sample handling practices.

Applications

• Routine cleaning and sterilization of glassware, metal instruments, and reusable lab consumables
• Preparation of HPLC, GC, and ICP-MS sample introduction components to eliminate carryover contamination
• Removal of flux residues from printed circuit boards and semiconductor wafers
• Extraction of analytes from solid matrices in environmental and food testing labs
• Disaggregation of aggregated nanoparticles and biological suspensions prior to DLS or TEM analysis
• Decontamination of endoscopes and dental tools in clinical research settings

FAQ

Is the CPX5800H-C suitable for use with flammable solvents?
No. This unit is rated for aqueous and low-volatility aqueous-based solutions only. Flammable or highly volatile solvents require explosion-proof certified equipment meeting ATEX or IECEx directives.
Does the unit include a built-in heater calibration certificate?
No. Temperature calibration must be performed externally using a NIST-traceable thermometer; the instrument provides a dedicated calibration offset function for correction.
Can the transducers be replaced in the field?
Transducer replacement requires factory service due to precision bonding and acoustic impedance matching requirements.
What is the expected service life under continuous daily use?
With proper maintenance—including regular descaling, adherence to max fill lines, and avoidance of abrasive cleaners—the system demonstrates >5 years MTBF in typical academic and industrial lab deployments.
Are accessories included with purchase?
The standard configuration includes the main unit and sound-dampening lid only. Baskets, racks, and specialized holders are available as optional accessories.
