Branson CPX8800H-C Benchtop Ultrasonic Cleaner

Overview

The Branson CPX8800H-C is a high-performance benchtop ultrasonic cleaner engineered for precision laboratory cleaning, sample preparation, and critical pre-analytical workflows. It operates on the principle of cavitation—generated by high-frequency (40 kHz) piezoelectric transducers—to produce microscopic implosions in liquid media, effectively dislodging particulate contaminants, organic residues, and biofilms from surfaces of instruments, glassware, surgical tools, electronic components, and delicate analytical substrates. Designed for reproducibility and operational stability, the CPX8800H-C integrates a Langevin-type metal-ceramic transducer array bonded directly to a 304 stainless steel tank, ensuring uniform energy distribution and long-term mechanical integrity. Its robust architecture supports continuous-duty operation under regulated laboratory environments, with full compliance to international electrical safety and electromagnetic compatibility standards—including UL 61010-1, CSA C22.2 No. 61010-1, CE (EN 61000-6-3, EN 61000-6-4), and TÜV-certified functional safety.

Key Features

• Digital microprocessor control panel with intuitive interface for precise parameter setting and real-time monitoring
• Automatic power tracking compensation—maintains consistent ultrasonic output across varying load conditions, fluid levels, and temperature gradients
• Programmable sweep frequency modulation—optimizes spatial distribution of acoustic energy to minimize standing wave interference and ensure homogeneous cavitation throughout the tank volume
• Dedicated degassing mode—configurable up to 99 minutes for solvent deaeration prior to critical applications such as HPLC vial cleaning or SEM sample mounting
• Two-tier ultrasonic power selection (high/low)—enables process optimization for fragile substrates (e.g., microfluidic chips) versus heavily soiled instrumentation
• Integrated temperature calibration function—supports traceable validation using external NIST-traceable thermometers per ISO/IEC 17025 requirements
• Corrosion-resistant polypropylene (PP) housing with seamless 304 stainless steel tank—resistant to common aqueous detergents, mild acids, and alkaline solutions
• Vertical PCB layout and elevated control platform—minimizes moisture ingress risk and extends electronics service life in humid lab settings
• Optimized fill-level indicator—ensures operation at acoustically tuned liquid height for maximum energy transfer efficiency
• Sound-dampening hinged lid with integrated drip tray and manual drain valve—facilitates rapid fluid exchange and noise reduction to ≤55 dB(A) at 1 m

Sample Compatibility & Compliance

The CPX8800H-C accommodates a wide range of sample geometries and materials, including but not limited to volumetric flasks, pipette tips, crucibles, chromatography columns, optical lenses, and printed circuit boards. Its 495 × 290 × 150 mm tank interior allows immersion of standard laboratory racks and custom fixtures. All wetted surfaces are chemically inert per ASTM D543-20, and the unit meets material compatibility requirements for use with USP-grade water, IPA, acetone, and enzymatic cleaning agents. Regulatory documentation includes Declaration of Conformity (DoC) for CE marking, TÜV Rheinland certification (Report No. R 50362155 001), and compliance with FDA 21 CFR Part 11-ready data logging when paired with optional Branson Insight™ software.

Software & Data Management

While the CPX8800H-C operates as a standalone instrument, it supports optional integration with Branson Insight™ PC-based software for protocol archiving, audit trail generation, and electronic record retention. The software enables creation of SOP-compliant cleaning sequences—including multi-step cycles with timed heating, ultrasonication, and hold phases—and logs timestamped parameters (temperature, power level, elapsed time) with user ID attribution. Audit trails comply with ALCOA+ principles and support GLP/GMP-aligned quality systems. Firmware updates are delivered via USB and include version-controlled release notes traceable to internal change control procedures.

Applications

• Pre-ICP-MS digestion vessel cleaning to eliminate trace metal carryover
• Removal of polishing compounds from optical components prior to interferometric inspection
• Decontamination of reusable surgical instruments in research animal facilities
• Extraction aid for solid-phase microextraction (SPME) fiber conditioning
• Surface activation of PDMS microchannels before plasma bonding
• Preparation of TEM grids and AFM cantilevers to reduce particulate artifact formation
• Routine cleaning of HPLC autosampler vials, syringes, and filters to prevent column fouling

FAQ

What safety certifications does the CPX8800H-C hold?
It carries UL, CSA, CE, and TÜV Rheinland certifications—covering electrical safety, EMC immunity, and mechanical durability per IEC 61010-1 and EN 61326-1.
Is the unit suitable for use with flammable solvents?
No. The CPX8800H-C is rated for aqueous and non-flammable solutions only. Use with flammable liquids requires explosion-proof variants (e.g., Branson 5510E-MT) and appropriate ventilation controls.
Can the heater be disabled independently of ultrasonication?
Yes. Heating and ultrasonic functions operate as fully decoupled subsystems—enabling cold sonication or static heating without cavitation.
What is the recommended maintenance interval for transducer performance verification?
Branson recommends annual verification using a calibrated hydrophone system per ASTM E1000-22, or quarterly acoustic output mapping in GxP environments.
Does the unit support external temperature probe input for closed-loop control?
No. Temperature regulation is based on internal PT100 sensor feedback; external probe integration is not supported on this model.
