STA 8000 Hardware Overview
The STA 8000 Simultaneous Thermal Analyzer offers performance, reliability and productivity
you can depend on. Designed with routine and research applications in mind, the STA 8000
applies leading edge sensor technology to yield higher accuracy and quality results.
The STA 8000 is controlled by PerkinElmer's Pyris software on the computer to which the
analyzer is connected. The information it provides is essential to industries such as plastics
and polymers; automotive; semiconductors and electronics; adhesives; paints and coatings;
fuels; ceramics, clays, and soil; food; pharmaceuticals; and medical devices and equipment.
The STA 8000 has an integrated cooling jacket, in which you can use various types of cooling
liquids with temperatures higher than 15 °C (non-condensing). During operation, the cooling
liquid flow rate should be between 0.5 and 1 l/min. The cooling liquid should be at a
temperature such that there is no condensation inside the analyzer. The recommended
cooling device is the Polyscience Chiller (P/N N5370220/N537-0221 for 120 V and 220 V
respectively).
The STA 8000 has a top-loading microbalance. There are two platforms that connect to the
microbalance via the sensor. When seen from the front of the analyzer, the right-hand
platform is for a reference pan, and the left-hand platform is for the sample pan. The top-
loading balance has many advantages over a hangdown wire design. With this design,
however, placement of the sample in the sample pan and of the sample pan on the platform
is very important. The microbalance is very sensitive to sample positioning.
The furnace has a large isothermal zone. The sample and reference positions in the
STA 8000 are approximately in the middle of the isothermal zone. This increases
reproducibility of temperature measurements.
The rapid cooling rate of the furnace is achieved by mounting the furnace in a liquid-cooled
jacket. To reduce the heating power at high temperatures, the cooling jacket is nickel-plated.
Also, there is forced air cooling. A small air pump is mounted inside the instrument and
activated by clicking the Cooling Air button on the control panel. Liquid cooling is also used to
keep the temperature of the balance housing constant. The cooling jacket is mounted on and
thermally insulated from the balance housing. Temperature gradients are eliminated as much
as possible.
