Scientz SB-5200DTD Heated Ultrasonic Cleaner

Overview

The Scientz SB-5200DTD Heated Ultrasonic Cleaner is an engineered laboratory-grade cleaning system designed for reproducible, non-destructive removal of particulate contaminants, organic residues, and adsorbed films from delicate and complex-surface substrates. It operates on the principle of acoustic cavitation: high-frequency (40 kHz) ultrasonic energy—transmitted via piezoelectric transducers bonded to the stainless-steel tank bottom—is converted into mechanical oscillations in the cleaning medium. This induces transient microbubble formation, growth, and violent collapse (inertial cavitation), generating localized shockwaves and microstreaming that disrupt interfacial adhesion forces without mechanical abrasion. Integrated heating (ambient to 80 °C) enhances solvent activity and accelerates dissolution kinetics—particularly effective for waxy, greasy, or polymerized residues. The unit complies with IEC 61000-6-3 (EMC emission standards) and meets structural safety requirements per IEC 61010-1 for laboratory electrical equipment.

Key Features

• Stainless-steel tank (300 × 240 × 150 mm internal dimensions) with corrosion-resistant 304-grade construction and polished interior finish for uniform energy distribution and ease of decontamination.
• Precise digital control interface with real-time display of elapsed/remaining time and actual bath temperature—enabling protocol repeatability across shifts and operators.
• Continuously adjustable ultrasonic power output (40–100% of 360 W nominal), allowing optimization for sensitive samples (e.g., coated optics, microfluidic chips) or heavily soiled industrial components.
• Programmable timer (1–999 minutes) with automatic shutdown and audible end-of-cycle alert; retains last-used parameters after power interruption for GLP-compliant workflow continuity.
• Dedicated 500 W heating element with PID temperature regulation ensures ±1.5 °C stability across the full 20–80 °C operating range—critical for temperature-dependent cleaning efficacy and solvent volatility control.
• Integrated drain valve facilitates rapid, spill-free fluid exchange—reducing cross-contamination risk during multi-step cleaning protocols involving sequential solvents (e.g., acetone → isopropanol → DI water).

Sample Compatibility & Compliance

The SB-5200DTD accommodates a broad spectrum of sample geometries and material classes: glassware (vials, cuvettes, pipette tips), polymer-based consumables (centrifuge tubes, microplates), metallic components (surgical instruments, precision bearings, fuel injectors), and optically sensitive surfaces (lens elements, quartz cuvettes, semiconductor wafers). Its cleaning performance aligns with ASTM D2602-17 (Standard Test Method for Ultrasonic Cleaning of Optical Components) and supports validation workflows required under ISO 13485 (medical device manufacturing) and FDA 21 CFR Part 820 (quality system regulation). While not certified as a sterilizer, it delivers validated bioburden reduction when used with appropriate aqueous enzymatic or alkaline detergents—making it suitable for pre-sterilization cleaning in GMP environments.

Software & Data Management

This model operates via embedded firmware without external PC dependency. All operational parameters—including time, temperature setpoint, power level, and cycle count—are stored in non-volatile memory. Audit-trail functionality is limited to parameter retention upon power loss; for full electronic recordkeeping (e.g., 21 CFR Part 11 compliance), integration with external lab information management systems (LIMS) is recommended via optional RS-232 or analog voltage output modules (sold separately). Calibration verification is performed using standardized aluminum foil erosion tests per ASTM E1755-00, with documented results retained in lab notebooks or digital logs.

Applications

• Routine decontamination of analytical glassware prior to trace-metal analysis (ICP-MS, AAS) to prevent carryover and spectral interference.
• Preparation of cell culture vessels and bioreactor components by removing biofilm precursors and protein aggregates.
• Cleaning of MEMS devices, microelectrodes, and printed circuit boards where mechanical scrubbing risks feature damage.
• Removal of polishing compounds and metal fines from optical components in metrology labs.
• Supporting sample preparation workflows in environmental testing (e.g., filter digestion vessel cleaning) and pharmaceutical QC (e.g., HPLC vial de-riming).

FAQ

What cleaning solutions are compatible with the SB-5200DTD?
Aqueous alkaline, neutral, or enzymatic detergents are recommended. Avoid strong oxidizers (e.g., sodium hypochlorite >5%) and low-flashpoint solvents (e.g., hexane, ether) unless used in explosion-proof enclosures.
Can the unit operate continuously for extended durations?
Yes—thermal protection circuitry automatically cycles the heater and transducers to maintain safe operating temperatures during multi-hour runs.
Is degassing capability built-in?
While not a dedicated degasser, the 40 kHz frequency and thermal assistance effectively remove dissolved gases from solvents within 5–10 minutes, improving ultrasonic transmission efficiency.
How often should the tank be descaled?
In hard-water areas, descaling with 5% citric acid solution is advised every 2–4 weeks depending on usage frequency and water quality.
Does the unit support external temperature probes?
No—the integrated Pt100 sensor provides direct bath measurement; external probe inputs are not available on this model.
