Rigaku Corporation, a Group company of Rigaku Holdings Corporation, has launched STAvesta, a thermal analyzer that simultaneously measures a sample’s weight and change in calorific value during heating. STAvesta responds to needs in a wide array of fields where thermal analysis is required. It is expected to find use in a wide variety of material-analysis applications for the development of advanced features and complex materials.

Dramatically Reduces Workload
In conventional thermal analysis, baseline adjustment must be performed by hand before measurement can begin. This process can be time-consuming and frustrating, particularly for novice users. Rigaku’s newly developed FlatBlank, a baseline auto-adjustment feature, automates this process, dramatically reducing waiting time associated with the process. Measurement can begin as soon as preparations are ready, enabling smooth setup after sample insertion and improving work efficiency overall. The benefits are particularly pronounced in workplaces conducting R&D handling multiple samples.

Key Features of STAvesta

• Broad support for a wide range of users
  STAvesta easily switches among seven types of electric furnace¹ according to purpose and measurement conditions. A real-time imaging feature enables samples to be observed during measurement, contributing to improved speed and accuracy in R&D.

• Vestaeye, a new, world-first feature, provides self-diagnosis for constant monitoring of device status.
  Before and during measurement, the device monitors itself constantly for signs of abnormality. Users can confirm at a glance whether the device is functioning correctly before starting measurement, so waste of precious samples is eliminated.
• Next-generation thermal analysis features for outstanding temperature-control performance
  In thermal analysis, when a temperature is set for a sample, the sample may fail to heat up to that setting or may heat up above that setting, precluding accurate measurement. Rigaku’s new temperature control feature dramatically reduces this problem of incorrect temperature. Samples are heated to and held at the required temperature in strict accordance with the preset temperature program. As a result, researchers can easily obtain the intended reactions and obtain stable measurement.
• Rapid processing of up to 52 samples in a compact device
  STAvesta’s automatic sample changer dramatically increases the number of samples that can be handled from 28 in the previous model to 52. With 2.3 times the transport speed of the previous model and support for up to 1,000 continuous measurements, STAvesta achieves superb measurement efficiency. The tray section supports gas flow, making it ideal for measurement of powders that are prone to moisture absorption. STAvesta is designed so that attachment of the automatic sample changer does not increase its footprint, assuring industry-leading space-saving performance.
