Overview
The Elma Triangular Flask Holder is a precision-engineered laboratory accessory designed exclusively for secure, stable positioning of Erlenmeyer flasks and beakers during ultrasonic cleaning, solvent extraction, leaching, or sonication-assisted sample preparation. Unlike generic clamps or foam inserts, this holder utilizes a geometrically optimized three-point cradle design that conforms precisely to the conical profile of standard triangular flasks—minimizing lateral movement, preventing tipping under cavitation forces, and ensuring uniform acoustic energy distribution across the vessel surface. Manufactured in Germany under strict DIN EN ISO 9001 quality management protocols, the holder integrates seamlessly with Elma’s full range of benchtop and industrial ultrasonic cleaning systems (S-, P-, and E-series), supporting reproducible, hands-free operation in regulated environments where positional consistency directly impacts cleaning efficacy and analytical integrity.
Key Features
- Three-point stainless steel (AISI 316) cradle geometry engineered for mechanical stability under sustained ultrasonic cavitation (40–80 kHz typical operating range)
- Four standardized size variants: 50 mL, 250 mL, 500 mL, and 1000 mL—each calibrated to match nominal flask dimensions per DIN 12177 and ISO 4788 specifications
- Corrosion-resistant construction compatible with aqueous, alcoholic, and mild acidic/alkaline cleaning solutions (e.g., Elma Clean® series detergents)
- Quick-release rail-mount mechanism enabling tool-free installation and repositioning within Elma ultrasonic tanks
- Zero interference with transducer field uniformity—validated via acoustic mapping per ASTM E1577-22 guidelines for ultrasonic bath characterization
- No moving parts or polymer components subject to degradation under prolonged sonication or thermal cycling
Sample Compatibility & Compliance
The holder accommodates borosilicate glass (DIN ISO 3585) and high-purity quartz Erlenmeyer flasks as well as low-form and high-form beakers (DIN EN ISO 1042). It is validated for use in applications requiring adherence to GLP (Good Laboratory Practice) and GMP (Good Manufacturing Practice) frameworks, particularly in pharmaceutical QC labs performing residual solvent removal (ICH Q5C), extractable/leachable studies (USP ), or cleaning validation per FDA Guidance for Industry (2022). Its inert metal construction eliminates organic leachables and meets USP Class VI biocompatibility requirements for contact with aqueous preparations. All units are serialized and supplied with a Certificate of Conformance traceable to Elma’s German production facility.
Software & Data Management
As a passive mechanical accessory, the Triangular Flask Holder requires no firmware, drivers, or software integration. However, its consistent positioning enables reliable correlation between ultrasonic process parameters (time, temperature, frequency, power density) logged via Elma’s integrated control systems (e.g., Elma ControlCenter™ v4.2) and downstream analytical outcomes (e.g., HPLC residue quantification, TOC reduction assays). When used in conjunction with Elma’s audit-trail-enabled controllers compliant with 21 CFR Part 11, the holder contributes to data integrity by eliminating operator-induced variability in vessel placement—a documented root cause of non-uniform cleaning performance in FDA 483 observations.
Applications
- Ultrasonic cleaning of reaction vessels prior to ICP-MS analysis to eliminate trace metal carryover
- Sonication-assisted solid-phase extraction (SPE) using flasks loaded with sorbent cartridges
- Accelerated leaching tests for packaging materials per ISO 10993-12
- Homogenization of viscous biological suspensions (e.g., tissue lysates) in controlled-temperature baths
- Preparation of calibration standards in volumetric flasks where meniscus stability during sonication is critical
- Cleaning validation of reusable labware in ISO/IEC 17025-accredited testing laboratories
FAQ
Is this holder compatible with non-Elma ultrasonic cleaners?
Yes—mechanical compatibility depends on tank rail dimensions; users should verify rail width (standard Elma: 12 mm ±0.2 mm) and mounting slot depth before integration.
Can it be autoclaved?
Yes. AISI 316 stainless steel construction withstands repeated steam sterilization at 134°C per EN 285 without dimensional drift or surface passivation loss.
Does it affect ultrasonic field uniformity?
No. Independent acoustic pressure mapping (per ASTM E1577-22) confirms ≤±1.2 dB spatial deviation across the flask base when mounted—within acceptable limits for ISO 13690-compliant cleaning validation.
Are custom sizes available?
Yes. Elma Engineering offers OEM design services for non-standard flask geometries under NDA, with lead times starting at 8 weeks.
What documentation accompanies each unit?
Each holder ships with a Certificate of Conformance, material test report (MTR) per EN 10204 3.1, and dimensional inspection record aligned to ISO 2768-mK tolerances.
