PULUODY PS3100-3L Ultrasonic Cleaner & Degassing Bath

Overview

The PULUODY PS3100-3L Ultrasonic Cleaner & Degassing Bath is an engineered solution for precision cleaning, degassing, and deaeration of small-volume laboratory samples. Based on piezoelectric transducer-driven cavitation at a fixed frequency of 43 kHz, the unit generates controlled acoustic energy within the stainless-steel tank to induce microbubble implosion—mechanically dislodging particulate contaminants, organic residues, and entrapped air from surfaces and within viscous or volatile liquids. Designed for reproducible operation in QC labs, R&D environments, and cleanroom-adjacent workflows, it supports critical pre-analytical preparation steps including solvent degassing prior to HPLC mobile phase preparation, removal of occluded air from resin-based casting media, and particle-free cleaning of optical components, filtration membranes, and microfluidic devices.

Key Features

• Microprocessor-controlled operation with backlit LCD interface for intuitive setting and real-time monitoring of time, temperature, and power level.
• Adjustable ultrasonic power output (0–100 W) enables optimization across sample types—from delicate biological substrates to robust metal parts—without compromising cavitation efficiency.
• Programmable heating function (0–80 °C) with PID temperature regulation ensures thermal stability during extended cleaning or degassing cycles; actual and setpoint temperatures are concurrently displayed.
• Dual-phase oscillation mode (not dual-frequency) enhances uniform energy distribution across the 3 L tank volume, minimizing standing-wave dead zones and improving cleaning homogeneity.
• One-piece seamless SUS304 stainless-steel tank (240 × 140 × 100 mm internal dimensions) eliminates weld seams that could harbor residue or compromise corrosion resistance—critical for ISO 14644-compliant cleanroom support applications.
• Integrated sound-dampening lid reduces operational noise to ≤55 dB(A) at 1 m distance, meeting occupational safety guidelines for continuous lab use.
• Digital timer range: 1–99 minutes with automatic shutdown and non-volatile memory retention—even after power interruption.
• Stainless steel mesh basket included for sample suspension; external chassis fabricated from brushed stainless steel with anti-corrosion surface treatment.

Sample Compatibility & Compliance

The PS3100-3L accommodates a broad range of sample formats—including glass vials, quartz cuvettes, ceramic filters, silicon wafers, and polymer microplates—provided they fit within the tank’s internal footprint and are compatible with aqueous or low-viscosity organic solvents (e.g., isopropanol, ethanol, acetone). It is not intended for use with highly flammable solvents without vapor extraction or for sterilization-grade microbial inactivation. While not certified to IEC 61000-4 electromagnetic compatibility standards or FDA 21 CFR Part 11 out-of-the-box, its programmable parameters, audit-ready timer logs, and stable thermal control support GLP/GMP-aligned documentation practices when integrated into validated SOPs. The unit complies with GB/T 17249.1–2021 (Chinese national standard for ultrasonic cleaners) and meets CE-equivalent electrical safety requirements per GB 4793.1.

Software & Data Management

This model operates via embedded firmware without external PC connectivity or proprietary software. All operational parameters—including elapsed time, current temperature, applied power level, and cycle completion status—are retained in non-volatile memory and accessible via the front-panel LCD. No data export capability is provided; however, manual logging of cycle parameters satisfies basic traceability needs for ISO/IEC 17025-accredited laboratories performing routine instrument qualification (IQ/OQ). For regulated environments requiring electronic records, integration with third-party environmental monitoring systems is feasible via analog voltage output (optional accessory) or external digital timer relay interfaces.

Applications

• Pre-HPLC solvent degassing to eliminate bubble formation in pump heads and detectors.
• Cleaning of NAS 0-grade sampling bottles and electronic-grade solvent containers used in semiconductor process chemistry.
• Removal of entrapped air from epoxy resins, photoresists, and silicone gels prior to curing or casting.
• Particle-free preparation of membrane filters (e.g., 0.22 µm PVDF) for liquid particle counting per USP and ISO 11171.
• Surface decontamination of reusable labware—especially items with complex geometries or blind holes where manual wiping is insufficient.
• Supporting ASTM D2276 (fuel particulate contamination) and ISO 4406 (hydraulic fluid cleanliness) sample preparation protocols.

FAQ

Is the PS3100-3L suitable for cleaning delicate optical lenses or microelectronic components?
Yes—when operated at reduced power (30–50% of maximum) and using low-surface-tension, non-ionic aqueous solutions, it delivers effective cleaning without mechanical abrasion or thermal stress.
Does the unit include automatic drainage functionality?
No—drainage is performed manually via a bottom-mounted valve; no pump or gravity-fed siphon system is integrated.
Can the heater be disabled while retaining ultrasonic operation?
Yes—temperature control is fully independent of ultrasonic activation; users may run cold sonication cycles exclusively.
What is the expected service life of the transducers under continuous daily use?
With proper maintenance (regular descaling, avoidance of dry operation), the piezoelectric stack assemblies typically maintain >90% nominal output intensity for ≥5,000 operational hours.
Is calibration documentation available for this model?
Factory calibration certificates for frequency and power output are available upon request; field verification requires external ultrasonic power meter (e.g., calorimetric or radiation-force type) per ASTM E1000.
