Simultaneous Thermal Analyzer – STA 449 F3 Jupiter® Analyzing & Testing
Open the catalog to page 1Flexible, Sophisticated & Technically Outstanding Simultaneous Thermal Analysis generally refers to the simultaneous application of Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC) to one and the same sample in a single instrument. The advantages are obvious: The test conditions are perfectly identical for the TGA and DSC signals (same atmosphere, gas flow rate, vapor pressure on the sample, heating rate, thermal contact to the sample crucible and sensor, radiation effect, etc.). Furthermore, sample throughput is improved as more information can be gathered from each test...
Open the catalog to page 2The NETZSCH STA Eco-Line 70% LESS ENERGY AND COST. NO EXTERNAL TEMPERATURE CONTROL NEEDED. To obtain exact Thermogravimetric results with low drift behavior, most manufacturers have to resort to thermostatic control using a water cycle. Having to run the thermostat continuously requires a lot of energy and produces waste heat, which subsequently needs to be regulated by air conditioning. NETZSCH has succeeded in removing the external thermostat. The weighing chamber’s temperature is now regulated electronically, while maintaining excellent temperature stability. By removing the thermostat,...
Open the catalog to page 3World-Leading Flexibility for Your Applications The STA 449 F3 Jupiter® combines a high-perfor ance Heat-Flux DSC m with a submicrogram-resolution thermobalance, thereby offering an unmatched sample load and measurement range. The Simultaneous Thermal Analyzer can easily be adjusted to nearly any possible application by selecting the optimum furnace, installing the most appropriate sensor and using the proper accessories. The robust system setup, userfriendly software and flexible design along with the wide range of different options make the system an ideal tool for quality control and...
Open the catalog to page 4Top-Loading – The Standard for Balance Systems Stability, Low Drift and High Sample Loads Defined Atmosphere Conditions – Vacuum-Tight Design The STA 449 F3 Jupiter® is a top-loading system using a balance design that has been standard for a long time in other types of scales – in laboratories and even in the kitchen at home or in a supermarket, most balances have been top-loading for decades. The reasons are simple: These systems combine ideal performance with easy handling. The balance system of the STA 449 F3 Jupiter® offers high sample loads (up to 35 grams) and measurement range (35...
Open the catalog to page 5Ten interchangeable furnaces are available to accommodate different application areas across the entire temperature range (-150°C to 2400°C). A double furnace hoist allows the simultaneous installation of two different furnaces for improved sample throughput or for low- and high-temperature tests with the same instrument. The furnaces can easily be changed by the operator. Therefore, the system is adaptable to any future application range. For standard STA measurements, the silicon carbide furnace (SiC) is the robust workhorse in your laboratory, operating from ambient temperature to...
Open the catalog to page 6Highest Temperatures The tungsten heating element allows for measurements under helium atmosphere from room temperature to 2400°C. Measurements in Humid Atmospheres The copper furnace is ideal for measurements under relative humidity between room temperature and 100°C. For this purpose, a humidity generator is available which offers a maximum dewpoint of 80°C corresponding to 47% molar concentration. In addition, the copper furnace can be used for conventional STA measurements including determination of the specific heat capacity up to 500°C. The water-vapor furnace covers the broad...
Open the catalog to page 7The Right Sensor for Your Demands The STA 449 F3 Jupiter® can be equipped with different sensor types. TGA sensors with slip-on plates or large crucibles (up to 5 ml) allow tests on large sample volumes and masses. TGA-DTA sensors can be used for applications such as routine tests or measurements on aggressive sample substances. For special applications such as tests under corrosive atmospheres, the protected sensors can be employed. The TGA-DSC and TGA-DSC-cp sensors are used for most tests and allow quantitative DSC testing simultaneously to the TGA results. The cp versions additionally...
Open the catalog to page 8Standard Type S Sensors -Workhorse and Specialty In the high-temperature range, type S sensors combine a broad temperature range from room temperature to 1650°C with high sensitivity. For measurements in the presence of corrosive gases, the TGA-DTA sensor with protected thermocouples provides safe conditions without adversely affecting the sensitivity. High Sensitivity in the Lower Temperature Range The type P sensors are standard in the lower temperature range; they are ideally suited for the steel furnace. All sensors equipped with thermocouple E or K are characterized by the highest...

Optionally available is a metalhoused mass flow control system (MFC) for purge and protective gases, offering optimum control of the atmosphere around the sample. Well defined gas flow conditions are crucial for accurate interpretation of the measured effects, e.g., to differentiate between oxidation...
Open the catalog to page 10Automatic Sample Changer An automatic sample changer for up to 20 samples is optionally available. The sample changer guarantees optimal crucible placement and maximum throughput. Preprogramming allows measurements to be carried out during the night or weekend. The software can automatically carry out analyses using predefined macros. A wide range of crucibles (aluminum, silver, gold, copper, platinum, alumina, zirconia, graphite, stainless steel, etc.) is available for nearly all possible applications and materials. For working in critical atmospheres, a "corrosive gas version" of the STA...
