Ningbo Scientz SB-3200D Ultrasonic Cleaner

Overview

The Ningbo Scientz SB-3200D Ultrasonic Cleaner is a benchtop general-purpose cleaning system engineered for precision laboratory environments where consistent, non-invasive removal of particulate, organic, and oily contaminants is required. It operates on the principle of acoustic cavitation: high-frequency (40 kHz) ultrasonic energy is transmitted into an aqueous or mild solvent-based cleaning bath via piezoelectric transducers bonded to the tank bottom. This generates controlled microbubble formation and implosive collapse—producing localized transient pressures exceeding 1000 atm and liquid jet velocities up to 400 m/s. These physical phenomena enable effective cleaning of complex geometries—including blind holes, narrow lumens, microfluidic channels, and textured surfaces—without mechanical abrasion or thermal degradation. Designed for ISO 13485-aligned cleanroom support and GLP-compliant lab workflows, the SB-3200D delivers reproducible cleaning performance across routine glassware decontamination, sample preparation, and pre-analytical device reprocessing.

Key Features

• Stainless steel tank (304 grade) and reinforced lid with integrated sound-dampening insulation—reducing operational noise to ≤55 dB(A) at 1 m distance
• Digital LED timer interface with 1–600 minute adjustable cycle duration and real-time countdown display
• Non-volatile memory retention: retains last-used time setting after power interruption
• Fixed-output 180 W transducer array optimized for 40 kHz resonance—ensuring stable cavitation density across full tank loading
• Compact footprint (300 × 240 × 320 mm) suitable for fume hoods, biosafety cabinets, and shared instrument benches
• No internal heater or power modulation circuitry—designed for ambient-temperature operation with external temperature-controlled baths if required

Sample Compatibility & Compliance

The SB-3200D accommodates standard laboratory consumables including borosilicate glassware (vials, beakers, pipette tips), stainless steel tools, silicone tubing, and polymer-based microcentrifuge tubes. It is compatible with water, ethanol/water mixtures, isopropanol, and low-surface-tension aqueous detergents meeting ASTM D4296 and ISO 15877 specifications. While not certified for terminal sterilization per EN 13060 or AAMI ST79, it supports pre-sterilization cleaning steps in accordance with FDA guidance for reusable medical devices (21 CFR §820.70). The unit complies with IEC 61010-1:2010 safety standards for electrical equipment used in laboratory settings and meets CE marking requirements under the EU Low Voltage Directive (2014/35/EU).

Software & Data Management

The SB-3200D is a standalone analog-digital hybrid instrument with no embedded software, network interface, or data logging capability. All operational parameters are set manually via front-panel controls and displayed on a 3-digit LED screen. For laboratories requiring audit trails or electronic records, integration with external environmental monitoring systems (e.g., Vaisala viewLinc or DeltaTrak FlashPaq) is possible using relay-triggered dry-contact outputs (optional accessory). No firmware updates or cybersecurity protocols apply, aligning with FDA 21 CFR Part 11 exemptions for Class I exempt devices lacking electronic record generation.

Applications

• Routine decontamination of volumetric flasks, culture dishes, and electrophoresis combs prior to analytical use
• Removal of residual PCR inhibitors from nucleic acid extraction columns and magnetic beads
• Pre-cleaning of HPLC injection valves, GC liners, and autosampler vial caps to prevent carryover
• De-gassing of mobile phases and calibration standards to eliminate bubble-induced baseline drift
• Surface preparation of SEM stubs and TEM grids prior to sputter coating
• Supporting USP and compliance by enabling residue-free cleaning of compounding equipment components

FAQ

Is the SB-3200D suitable for cleaning delicate optical components such as microscope objectives or fiber optic connectors?
Yes—when operated with deionized water or low-concentration surfactant solutions and limited to ≤300 s cycles, it effectively removes submicron particulates without surface etching or coating delamination.
Can this unit be used with flammable solvents like acetone or hexane?
No—this model lacks explosion-proof construction, intrinsically safe circuitry, or vapor recovery systems; only aqueous or Class I alcohol-based solutions below flash point thresholds are permitted.
Does the unit include a built-in drain valve or fill port for automated bath exchange?
No—tank refilling and emptying must be performed manually; optional external pump kits may be interfaced via gravity-fed inlet/outlet adapters.
What maintenance is required to sustain optimal cavitation performance?
Transducer coupling integrity should be verified quarterly via visual inspection of epoxy bonding; tank interior must be descaled every 200 operating hours using 5% citric acid solution to prevent quartz crystal fouling.
Is calibration documentation or traceable performance verification available?
Scientz provides factory test reports verifying nominal frequency output and power delivery; third-party validation per ASTM E1497 or ISO 13079-1 requires separate commissioning by accredited metrology providers.
