Branson CPX5800-C Benchtop Ultrasonic Cleaner

Overview

The Branson CPX5800-C is a general-purpose benchtop ultrasonic cleaner engineered for precision, repeatability, and long-term operational stability in laboratory and light industrial environments. It operates on the principle of high-frequency acoustic cavitation—generating controlled micro-bubbles in liquid media via piezoelectric transducers vibrating at 40 kHz. When these bubbles collapse near surfaces, they produce localized shockwaves and micro-jets that effectively dislodge particulate contaminants, organic residues, and biofilms from delicate instruments, glassware, surgical tools, electronic components, and sample preparation vessels. Designed for routine cleaning, degassing, and pre-analytical sample conditioning, the CPX5800-C delivers consistent energy distribution across its 9.5 L stainless steel tank (304 grade), supported by automatic power tracking and dual-power mode operation to maintain stable acoustic output under variable load conditions.

Key Features

• Automatic Power Tracking: Dynamically adjusts generator output to compensate for changes in load, temperature, or liquid level—ensuring stable cavitation intensity regardless of operator or application variability.
• Dual-Power Mode Selection: Switchable high/low power settings (180 W max) allow optimization for sensitive substrates (e.g., microfluidic chips, optical lenses) or heavily soiled items (e.g., metal fixtures, pipette tips).
• Professional Degassing Function: Dedicated degas mode enables extended (up to 99 min) low-intensity sonication to remove dissolved gases from solvents—critical for HPLC mobile phase preparation, solvent-based coating, or vacuum-compatible sample handling.
• Langevin-Type Transducer Assembly: Integrated metal-ceramic composite transducers mounted via advanced adhesive bonding ensure mechanical integrity, thermal stability, and minimal resonance drift over time.
• Corrosion-Resistant Construction: PP (polypropylene) outer housing resists acids, alkalis, and organic solvents; 304 stainless steel inner tank meets ASTM A240 standards for aqueous corrosion resistance.
• Ergonomic & Safety-Oriented Design: Elevated control panel prevents liquid ingress; vertical PCB layout minimizes moisture exposure; calibrated fill line ensures optimal acoustic coupling; hinged sound-dampening lid doubles as a drip tray with integrated drain valve.

Sample Compatibility & Compliance

The CPX5800-C accommodates a broad range of sample geometries—including beakers, flasks, Petri dishes, vials, syringes, and small instrumentation parts—within its internal dimensions of 292 × 241 × 152 mm. Its non-heated design makes it suitable for temperature-sensitive materials (e.g., polymers, biological specimens) where thermal degradation must be avoided. All units comply with electromagnetic compatibility (EMC) and safety requirements per FCC Part 18, CSA C22.2 No. 61010-1, UL 61010-1, and CE Directive 2014/30/EU. Certified by TÜV Rheinland to IEC 61010-1:2010, the device supports GLP-compliant workflows through traceable operation logs (when paired with optional data logging accessories) and meets foundational electrical safety benchmarks required for ISO/IEC 17025-accredited laboratories.

Software & Data Management

The CPX5800-C features an embedded digital controller with LED display and tactile membrane keypad—designed for intuitive, glove-friendly operation without reliance on external software or PC connectivity. While the unit does not include built-in USB or Ethernet interfaces, its timer and power settings are fully programmable and retain user-defined configurations after power cycling. For regulated environments requiring audit trails, optional third-party data loggers (e.g., compliant with FDA 21 CFR Part 11 when validated) may be deployed to record start/stop timestamps, duration, and power mode selections. Firmware updates are performed manually via authorized service centers to preserve system integrity and regulatory alignment.

Applications

• Routine cleaning of volumetric glassware, centrifuge tubes, and reusable labware prior to sterilization or analytical use
• Removal of flux residues, solder paste, and particulates from printed circuit boards (PCBs) and microelectronic assemblies
• Preparation of ultrapure water systems and filtration housings to minimize microbial carryover
• Degassing of HPLC solvents, buffer solutions, and casting resins to prevent bubble formation in detectors or molds
• Loosening of dried biological samples from microtiter plates and tissue culture flasks prior to extraction
• Supporting ASTM D2620, ISO 13485, and USP particle count validation protocols through standardized cleaning cycles

FAQ

Is the CPX5800-C compatible with flammable solvents?
No—this model is rated for aqueous and mild detergent solutions only. Flammable or highly volatile solvents require explosion-proof ultrasonic systems certified to ATEX or IECEx standards.
Can the unit operate continuously beyond 99 minutes?
Yes—selecting “continuous” mode bypasses the timer and sustains ultrasonic output until manually stopped.
What maintenance is required for long-term reliability?
Routine cleaning of the tank interior and lid gasket, periodic inspection of the drain valve seal, and verification of transducer adhesion integrity every 12 months (per Branson Field Service Protocol FSP-CPX-02).
Does the CPX5800-C support remote monitoring or integration into lab automation networks?
No native network interface is provided; however, dry-contact relay outputs (available via optional accessory module) enable basic start/stop signaling to PLCs or building management systems.
How does the CPX5800-C compare to older Branson 2200 series models?
The CPX platform introduces enhanced power regulation algorithms, improved transducer thermal management, updated safety certifications (TÜV vs. legacy UL-only), and a redesigned human-machine interface optimized for multi-user lab environments.
