- sorption,diffusion,
- surface tension,and density can be measured easily.
- Furthermore chemical reactions e.g.
- corrosion
- decomposition,and combustion will be recorded
- and production processes can be simulated (coating, polymerisation, dehydration, etc.).

With the magnetic suspension balance LINSEIS MSB PT 1, gravimetric measurements in a wide temperature and pressure range and under aggressive media can be done. Such a magnetic suspension balance consist of a balance for recording the measurement values, a suspension coupling which carries the weight of the sample, a sensor for the position measurement of the levitation part and a control unit to control the suspension coupling. The contact-less transmission of the sample weight is realized with a levitation magnet and a holding magnet. The levitation magnet consists of a permanent magnet and the holding magnet consists of an electromagnet hanging on the balance. The position sensor delivers the actual position of the levitation magnet and the PID controller makes a stable levitation position with the electromagnetic force as the actuating variable. Through the magnetic coupling a micro balance can be set up at environmental condition. Therefore the balance is protected from high temperatures, pressure and aggressive media. With the magnetic suspension balance dimensions like -
Linseis introduced the all new STA HP 3 (TGA+DSC) table top high pressure thermogravimetric, simultaneous thermal analysis instrument. The STA HP 3 is the result of 25 years of experience thermal analysis under high pressure. The superior high speed micro-furnace with a maximum temperature of 1200°C, top loading microbalance, true TG-DSC Thermogravimetry-differential scanning calorimetry design permit exiting new opportunities. The table top design, optional vapor generator and different gas dosing systems provides utmost flexibility. Worlds only top loading combined TG-DSC (Thermogravimeter and Differential Scanning Calorimeter). For experiments up to 1200°C and up to 150 bar in reactive or inert atmospheres. Easy user exchangeable TGA or TG-DSC plug and play sensors. The right choice for any given experiment gives you the flexibility to analyze TGA only experiments with volumes up to 1 ml or combined TGA-DSC analysis with up to 0.12 or 0.3 ml volume. TG-DSC Thermogravimetry-differential scanning calorimetry arrangement permits the combined analysis of weight change and caloric events like endothermal or exothermal reactions or phase transitions in one run and under the same temperature, gas and pressure conditions. -
The LINSEIS High Pressure STA ( High pressure Tg-DSC) delivers unsurpassed performance. The system can be used to determine simultaneous changes of mass (TG) and caloric reactions (HDSC) under defined atmosphere and high pressure (up to 50/150 bar) in the temperature range -170°C up to 1800°C. This instrument is unique because it is the only available high pressure TG-DSC worldwide. The unique characteristics of this product are high precision, high resolution and long term drift stability. The high pressure STA Platinum Series was developed to meet the challenging demands of the high temperature and high pressure applications. Main Application of High Pressure Thermogravimetry-Differential Scanning Calorimetry:- Pyrolysis Studies
- Gasification of Coal and Biomass
- Testing of Getter Materials (O2, H2, etc.)
- Metal reduction / oxidation studies

The STA PT 1000 is dedicated to analysis of organic materials in a relatively low temperature range up to 1000°C. The TG-DSC is a top loading Thermobalance, which offers a highly user-friendly design. Even at a sample weight of up to 10g the Tara is done electronically. The specially designed furnaces allow fast heating and cooling rates as well as a highly precise temperature control. The system can be optionally equipped with a coupling device for EGA (Evolved Gas Analysis). The instrument is highly suitable for thermal composition, thermal stability and oxidation studies.
