Sonicators for ASTM Test and Practice Standards
Hielscher ultrasonicators deliver controlled, repeatable sonication for ASTM methods involving sonic shear, ultrasonic extraction, cavitation erosion, and MBEC biofilm detachment.
Why Sonicator Selection Matters for ASTM Testing
ASTM methods that use ultrasonic energy depend on defined acoustic cavitation and vibration, controlled amplitude, reproducible sample positioning, and consistent temperature management. The wrong ultrasonic device can create insufficient cavitation, uneven treatment, excessive heating, or poor repeatability. Hielscher sonicators are designed for laboratory validation work with digital amplitude control, data recording, broad sonotrode compatibility, and robust continuous operation.

At-a-Glance Sonicator Selection Guide
| ASTM Standard | Test Purpose | How Sonication Helps | Recommended Sonicator Model |
|---|---|---|---|
| АСТМ D2603 | Sonic shear stability of polymer-containing oils, such as lubricating oils, transmission fluids, tractor fluids, hydraulic fluids, and other polymer-containing oils. | Probe-generated ultrasonic cavitation creates intense, repeatable shear forces. This accelerates mechanical degradation of shear-sensitive viscosity-index improvers and allows laboratories to measure permanent viscosity loss under controlled conditions. | UP400St with S24d22 sonotrode |
| АСТМ Д5621 | Sonic shear stability of hydraulic fluids containing polymeric viscosity modifiers. | Sonication exposes the hydraulic fluid to defined high-shear acoustic conditions. This helps determine whether polymer additives maintain viscosity or degrade under severe mechanical stress. | UP400St with S24d22 sonotrode |
| АСТМ Г32 | Cavitation erosion testing of metals, coatings, alloys, ceramics, and other engineering materials exposed to cavitation. | A vibrating ultrasonic sonotrode generates a controlled cavitation field in liquid. The repeated formation and collapse of cavitation bubbles produces measurable erosion, enabling comparison of material resistance to cavitation damage. | УИП1000HDT Alternatives: УИП500HDT или УИП2000HDT |
| ASTM E1979-21 | Ultrasonic extraction of paint, dust, soil, and air samples for lead determination. | Ultrasonic cavitation improves extraction efficiency by disrupting particles, increasing contact between sample and extraction solution, and accelerating release of lead for subsequent analytical determination. | УП200Хт for routine laboratories УП400Ст for higher intensity or throughput |
| ASTM E2799-22 | Testing disinfectant efficacy against Pseudomonas aeruginosa biofilm using the MBEC assay. | Plate-wide sonication detaches biofilm cells from the 96-peg MBEC lid into the wells for recovery and quantification. Uniform microplate sonication improves comparability across wells and supports high-throughput biofilm testing. | Ультразвуковой аппарат для микропланшетов UIP400MTP |
Recommended Hielscher Sonicators for ASTM Standards
The following ASTM standards use sonication as a core test step or as a sonication-assisted sample preparation step. Select the model that matches the required sample geometry, power level, and throughput.
АСТМ D2603 – Sonic Shear Stability of Polymer-Containing Oils
ASTM D2603 evaluates the shear stability of polymer-containing oils by measuring permanent viscosity loss after irradiation in a sonic oscillator. The test is used for fluids such as lubricating oils, transmission fluids, tractor fluids, and other polymer-modified oils where viscosity-index improvers may degrade under intense shear.
Core sonication function: intense and focused cavitation and shear generated by an ultrasonic probe.
Critical control points: fixed test time, defined probe geometry, sample temperature control, and reproducible immersion depth.
Typical result: viscosity before and after sonication to quantify permanent viscosity loss.
Recommended sonicator: Hielscher UP400St with S24d22 sonotrode.
The UP400St is the preferred Hielscher configuration for ASTM D2603 because it provides 400 W ultrasonic power at 24 kHz, precise amplitude control, integrated temperature monitoring, and compatibility with the S24d22 probe geometry used for sonic shear stability testing.

АСТМ Д5621 – Sonic Shear Stability of Hydraulic Fluids
ASTM D5621 measures the shear stability of hydraulic fluids by determining the final viscosity after ultrasonic irradiation in a sonic oscillator. It is especially relevant for hydraulic fluids containing shear-sensitive or shear-resistant polymer additives.
Core sonication function: accelerated polymer shear through acoustic cavitation.
Critical control points: ultrasonic horn selection, amplitude stability, temperature control, and consistent test duration.
Typical result: final viscosity or viscosity change after standardized sonic treatment.
Recommended sonicator: Hielscher UP400St with S24d22 sonotrode.
The UP400St is also the ideal choice for ASTM D5621. Its 24 kHz probe-type ultrasonic shear setup gives laboratories a compact, digitally controlled platform for repeatable hydraulic-fluid shear testing.

АСТМ Г32 – Cavitation Erosion Using Ultrasonic Vibratory Apparatus
ASTM G32 describes cavitation erosion testing using a vibratory apparatus. A specimen is exposed to high-frequency vibration – generated by a sonicator – in a liquid, producing the formation and collapse of cavities that cause measurable material loss. The method is used to compare cavitation erosion resistance of metals, coatings, and other engineering materials.

Core sonication function: controlled cavitation field generated by a vibrating sonotrode.
Critical control points: amplitude, specimen geometry, gap distance, liquid temperature, exposure time, and specimen mass loss measurement.
Typical result: erosion rate, cumulative mass loss, or comparative cavitation resistance.
Recommended sonicator: Hielscher UIP1000hdT.
The UIP1000hdT is an excellent Hielscher choice for ASTM G32 because its 1000 W, 20 kHz probe-type design provides the high, stable amplitude required for reproducible cavitation erosion studies. For lower or higher power requirements, Hielscher UIP500hdT and UIP2000hdT configurations are suitable alternatives.

ASTM E1979-21 – Ultrasonic Extraction of Paint, Dust, Soil, and Air Samples for Lead Determination
ASTM E1979-21 is an ultrasonic extraction practice for preparing environmental samples prior to analytical lead determination. It applies to matrices such as dry paint films, settled dust, soil, and air particulates from lead abatement, renovation, occupational hygiene, and environmental monitoring contexts.
Core sonication function: ultrasonic extraction to make lead available for subsequent analytical measurement.
Critical control points: extraction vessel, sonication time, temperature, acid matrix, and consistent energy transfer.
Typical result: extracted lead concentration determined by a downstream laboratory analytical method.
Recommended sonicator: Hielscher UP200Ht or UP400St.
For routine ASTM E1979 sample preparation, the UP200Ht is a strong laboratory choice for small to medium extraction volumes. The UP400St is recommended when higher intensity, larger sample throughput, or broader sonotrode flexibility is required.

ASTM E2799-22 – Testing Disinfectant Efficacy Against Pseudomonas aeruginosa Biofilm Using the MBEC Assay
ASTM E2799-22 specifies operational parameters for growing, treating, neutralizing, and recovering Pseudomonas aeruginosa biofilm in a high-throughput MBEC assay format. Biofilm grows on a 96-peg lid that corresponds to a 96-well receiver plate. After disinfectant exposure, sonication is used as a biofilm detachment and recovery step.
Core sonication function: simultaneous, reproducible detachment of biofilm from a 96-peg MBEC lid into microplate wells.
Critical control points: uniform ultrasonic energy across the entire plate, controlled exposure time, low cross-contamination risk, and cell recovery without excessive destructive energy.
Typical result: quantitative recovery of viable biofilm cells after disinfectant treatment.
Recommended sonicator: Hielscher UIP400MTP.
The UIP400MTP is ideal for ASTM E2799-22 because it is built for microtiter plates rather than single-vessel probe treatment. It delivers uniform ultrasound across the full plate, enabling simultaneous treatment of all wells and reproducible detachment of biofilms from MBEC peg lids. This makes it better suited than a handheld probe for high-throughput biofilm workflows, where consistent plate-wide energy distribution and sample-to-sample comparability are essential.

Часто задаваемые вопросы
What stands ASTM for?
ASTM originally stood for American Society for Testing and Materials. Today, the organization is officially called ASTM International, and it develops voluntary technical standards for materials, products, systems, and services.
What are the types of ASTM?
ASTM standards are commonly classified into several document types: test methods, specifications, practices, guides, classifications, and terminology standards. In scientific and industrial use, ASTM standards mainly define how to test, specify, classify, or describe materials and products.
What is the difference between ASTM, ISO, and DIN?
ASTM is a standards-development organization with strong origins in materials testing and product performance standards. ISO is an international standards organization that develops global standards through national member bodies. DIN is Germany’s national standards body and represents German interests in European and international standardization.
Is ASTM the same as ANSI?
No, ASTM develops and publishes technical standards, while ANSI coordinates the U.S. voluntary standards system and accredits standards developers. ASTM standards may be used in ANSI-related systems, but ASTM and ANSI are different organizations.
