Micro Compression Tester
Evaluates Compression Strength of Various of Micro Specimens.
The Shimadzu micro compression testers MCT Series evaluate the strength of micro components, micro particles generated in powder processing and fine fibers used in new materials.
Types of Testable Materials
- Ceramic particle
- Fine metallic powder
- Resin particles
- Food source powders
- Pharmaceuticals (micro-capsules)
- Fine fibers
Available Test Modes
- Compression Testing: Force increases until either the sample ruptures or a preset load is achieved.
- Load-Unload Testing: Force is increased to a preset max load point and then reduced to a preset minimum load point. By measuring the difference in displacement between the maximum and minimum point, the recovery rate percentage of the sample is calculable.
- Cyclic Testing: Test force is repeatedly increased and decreased up to 250 times to evaluate specimen fatigue properties.
A Design with Simplicity in Mind
Micrometer (Optical Head)
The micrometer optical viewing head measures the size of the specimen, which is sandwiched by two indicators to enable measurement up to 200µm at an increment of 0.1µm (with a x5O objective lens).
The standard x50 and optional x100 lenses are used in conjunction with the micrometer optical head to provide length measurements.
A test point is selected with the micrometer optical head and that point is then shifted to just below the indenter. The click-stop mechanism ensures accurate positioning of the specimen. The positioning accuracy of the unit is within ±5µm (±0.2µm can be achieved with careful handling).
Vertical Stage Shift Handle
The stage shifts smoothly using a single handle.
The test force range is from 9.8 to 4900mN or 1960mN. The electromagnetic method employed in the unit ensures high precision loading.
Instrument Status Indication Lamps
A lit red lamp (RUNNING) indicates the instrument is loading and should not be adjusted by the operator while a green lamp (READY) indicates that the operator can safely operate the indenter.
Compression Displacement Detector
The measurement detector provides dynamic compression displacement readings with a resolution as low as 0.001µm.
The following indenters are available:
- 50µm diameter flat indenter (standard)
- 500µm diameter flat indenter (optional)
- 115° triangular pyramid indenter (optional) (The triangular pyramid indenter is used for tests where the specimen is larger than 500µm and cannot be broken at a test load of 4900mN.)
Lower Pressure Plate Vise
This ergonomically constructed vise firmly secures the lower pressure plate. The standard supplied micrometer is then used to adjust the stage over a range of 25mm in the X-Y directions at increments of 0.0lmm. A digital micrometer is also available as an option.
