WIGGENS ECO Series Ultrasonic Cleaner

Overview

The WIGGENS ECO Series Ultrasonic Cleaner is a precision-engineered benchtop cleaning system designed for routine and demanding laboratory applications requiring consistent, non-abrasive removal of particulate, organic, and oily contaminants from delicate components. Operating on the principle of acoustic cavitation, the unit generates high-frequency mechanical vibrations—typically at 37 kHz—via piezoelectric transducers bonded to the stainless steel tank base. These vibrations propagate through the cleaning medium (e.g., aqueous detergent, ethanol, or specialized solvents), inducing rapid formation and collapse of microscopic vapor cavities. Each implosion releases localized energy exceeding 1000 atm, generating micro-jets and shockwaves that penetrate microstructures, blind holes, and complex geometries without surface damage. Unlike mechanical scrubbing or aggressive chemical immersion, this physical cleaning mechanism ensures high reproducibility across repeated cycles and eliminates operator-dependent variability.

Key Features

• Five scalable models (UE03, UE06, UE10, UE15, UE22) covering 3 L to 22 L working volumes—optimized for small parts, glassware batches, or multi-rack instrumentation components.
• Full AISI 304 stainless steel construction: seamless tank interior, corrosion-resistant exterior, and integrated stainless steel mesh basket for uniform part suspension and acoustic coupling.
• Digital timer with precise 1–99 minute resolution; automatic shutdown upon completion ensures process repeatability and prevents over-cleaning or solvent degradation.
• Integrated heating system (20–80 °C adjustable) enhances cleaning efficacy for waxy or viscous residues; temperature stability maintained within ±2 °C under load.
• Acoustic-dampening lid reduces ambient noise to ≤55 dB(A) at 1 m distance—critical for shared lab environments and long-duration cycles.
• Manual drain valve standard on UE06 and larger models (absent on UE03), facilitating rapid solvent exchange and residue removal between cleaning protocols.

Sample Compatibility & Compliance

The ECO Series accommodates a broad range of substrates including glassware (vials, cuvettes, pipettes), metal tools (tweezers, forceps, surgical instruments), ceramic filters, silicon wafers, printed circuit boards (PCBs), and optical components. It is explicitly rated for non-medical laboratory use and is not intended for sterilization, disinfection, or human tissue contact per ISO 13485 or FDA 21 CFR Part 820 requirements. The device complies with IEC 61010-1:2010 for safety of electrical equipment for measurement, control, and laboratory use. All models meet RoHS Directive 2011/65/EU and CE marking requirements for electromagnetic compatibility (EMC) and low-voltage directives.

Software & Data Management

As a standalone analog-digital hybrid instrument, the ECO Series does not incorporate embedded firmware, network connectivity, or data logging capabilities. Process parameters—including time, temperature setpoint, and power activation—are controlled via front-panel membrane switches and displayed on an LED readout. While it lacks audit trail functionality required under FDA 21 CFR Part 11 or GLP/GMP Annex 11, its mechanical simplicity ensures minimal calibration drift and long-term operational reliability. Users may document cleaning cycles manually using standardized lab notebooks or integrate the unit into validated SOPs with defined start/stop timestamps and operator signatures.

Applications

• Pre-analytical sample preparation: cleaning HPLC vials, GC autosampler trays, and spectrophotometer cells to eliminate carryover interference.
• Microelectronics: decontamination of MEMS devices, sensor housings, and solder paste residues prior to metrology or bonding.
• Materials science: removal of polishing compounds from metallographic specimens and oxide layers from semiconductor substrates.
• Quality control labs: routine maintenance of calibration standards, reference weights, and analytical balance components.
• Research facilities: cleaning of microfluidic chips, capillary electrophoresis tubing, and 3D-printed polymer scaffolds prior to cell seeding or imaging.

FAQ

Is the ECO Series suitable for cleaning medical devices intended for patient use?
No. This instrument is designated for non-medical laboratory applications only and does not meet ISO 17664 or AAMI ST79 requirements for reprocessing reusable medical devices.
Can I use flammable solvents such as acetone or ether in the tank?
No. Flammable or low-flashpoint solvents are strictly prohibited due to absence of explosion-proof design and intrinsic safety certification.
What is the expected service life of the transducers under continuous operation?
Under normal usage (≤4 hours/day, proper degassing, and regular descaling), transducer assemblies maintain >95% amplitude stability for ≥5 years, consistent with IEC 60068-2 environmental endurance testing.
Does the unit include a built-in degassing function?
No. Degassing must be performed manually by running the unit empty for 5–10 minutes before introducing samples and cleaning solution.
Are replacement baskets and lids available as spare parts?
Yes. Stainless steel mesh baskets (part numbers specific to each model) and acoustic lids are stocked globally through WIGGENS authorized distributors.
