Elma TS540 Cylindrical Sieve Cleaning System

Overview

The Elma TS540 Cylindrical Sieve Cleaning System is a purpose-engineered ultrasonic cleaning device designed exclusively for the efficient, non-destructive removal of particulate residue from precision mesh sieves—commonly used in pharmaceutical sieve analysis (e.g., USP , ASTM E11), particle size distribution testing, and quality control laboratories. Unlike general-purpose ultrasonic cleaners, the TS540 integrates a vertically oriented cylindrical chamber with a dedicated internal support structure that securely holds standard ASTM/ISO-compliant test sieves (e.g., 200 mm diameter, 25–50 mm depth) in optimal acoustic alignment. Its 35 kHz transducer array generates uniform cavitation fields within the 6.4 L tank volume, ensuring consistent energy delivery across the entire sieve surface—critical for preserving mesh integrity while achieving high-reproducibility cleaning outcomes. The system operates on standard European mains voltage (220–240 V AC) and complies with electromagnetic compatibility (IEC 61000-6-3) and safety directives (CE, RoHS), making it suitable for GLP-regulated environments where equipment traceability and operational consistency are mandatory.

Key Features

• Application-specific cylindrical chamber geometry optimized for vertical immersion of standard test sieves (e.g., ISO 3310-1, ASTM E11)
• 160 W ultrasonic power output at 35 kHz—engineered to balance cleaning efficacy with minimal mesh erosion risk
• Digital timer with precise 1–15 minute interval control; supports both single-cycle and continuous operation modes
• Ergonomic integrated handle and compact footprint (300 × 285 × 240 mm) for benchtop deployment in space-constrained QC labs
• Stainless steel tank construction (AISI 316-grade wetted surfaces) for corrosion resistance against aqueous and mild solvent-based cleaning solutions
• Thermal stability design ensures no active heating element—eliminates thermal distortion risks for calibrated sieves during cleaning

Sample Compatibility & Compliance

The TS540 accommodates standard 200 mm diameter wire mesh sieves (stainless steel or brass), perforated plates, and fine-mesh filtration discs up to 50 mm depth. It is validated for use with water, deionized water, and Elma-certified low-foaming alkaline or neutral pH cleaning agents (e.g., Elma Clean D, Elma Clean A). The system meets key regulatory prerequisites for analytical instrument qualification: its fixed-frequency, fixed-power architecture eliminates calibration drift associated with variable parameters—supporting IQ/OQ documentation under ISO/IEC 17025 and FDA 21 CFR Part 11-aligned workflows when paired with Elma’s optional audit-trail-capable software interface (sold separately). No moving parts or seals require periodic replacement, contributing to long-term metrological stability.

Software & Data Management

While the TS540 operates as a standalone unit with manual timer control, it is fully compatible with Elma’s optional Elmasonic Connect module—a USB-connected interface enabling remote start/stop, cycle logging, and timestamped operation records. When deployed in networked lab environments, this module supports integration into LIMS platforms via CSV export and satisfies ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate) for GMP-compliant sieve cleaning validation. Firmware updates are delivered via Elma’s secure portal, maintaining compliance with current IEC 62304 software lifecycle standards.

Applications

• Pharmaceutical: Pre- and post-sieve analysis cleaning per USP and EP 2.9.37 protocols
• Materials Science: Removal of metal powder residues from sintered stainless steel sieves used in additive manufacturing QA
• Food & Agriculture: Decontamination of flour and grain analysis sieves without compromising aperture accuracy
• Environmental Testing: Cleaning of sediment sieving meshes after ASTM D422 or ISO 11277 soil particle analysis
• Research Labs: Routine maintenance of custom-machined mesh substrates for filtration or catalyst support studies

FAQ

Is the TS540 compatible with ISO 3310-1 and ASTM E11 standard test sieves?
Yes—the internal cylindrical holder is dimensionally matched to 200 mm diameter sieves conforming to both standards, ensuring full submersion without lateral contact.
Does the TS540 include temperature control or heating functionality?
No. The TS540 is a non-heated system; this design prevents thermal expansion-induced calibration shifts in precision mesh apertures.
Can the ultrasonic frequency or power be adjusted?
No. The TS540 operates at a fixed 35 kHz / 160 W configuration—optimized specifically for sieve cleaning reproducibility and certified for routine use in regulated environments.
What cleaning solutions are recommended for use with the TS540?
Elma Clean D (alkaline) and Elma Clean A (neutral) are validated for residue removal without attacking stainless steel mesh; avoid chlorinated or highly acidic formulations.
Is the unit suitable for cleaning delicate medical device components?
While not intended for sterile reprocessing, the TS540 may be used for pre-sterilization cleaning of robust metallic probes or reusable surgical mesh holders—subject to internal validation per ISO 15883.
