D2020 Density

Eureka! Alpha’s D2020 Density instrument is based on the Archimedes’ principle where the upward buoyant force that is exerted on a test sample immersed in water is equal to the weight of the water that the sample displaces and acts in the upward direction.

D2020 Density utilizes the compound’s weight in air and in water to account for any environmental differences during testing, resulting in higher quality standards and increased precision.

Fully automated operation helps ensure repeatability while freeing the operator for other tasks in the lab. Additionally, rapid readings help reduce water absorption which translates into a more accurate reading. For even greater precision the specific gravity of the liquid is automatically corrected for temperature.

 

D2020 Density Hardness Instrument from Alpha Technologies

D2020 Hardness

Alpha’s Shore A and IRHD instruments are based on the test methods developed by Albert F. Shore in the 1920s to measure the hardness of materials. This method is the measure of how resistant a given material is to permanent indentation – that is, the measure of the depth of indentation created on the material with a specific force. Both versions provide highly repeatable measurements on rubber and polymer parts.

The International Rubber Hardness Degree (IRHD) – as defined in ISO 48 – is a fully automated measuring procedure preferred in Europe. The IRHD hardness value is read directly from the internal lookup table in Alpha’s Enterprise software.

The Shore A method – defined under ASTM D2240 – allows for a measurement of the initial hardness, or the indentation hardness after a given period of time.

In addition to its 20-sample automation cassette, D2020 Hardness instruments can be automatically rotated, allowing multiple readings per test sample.
