Rapid Prototyping Sinterstation 2000
Like many other rapid prototyping processes, the Sinterstation builds three-dimensional products on a layer by layer fashion. The source material is mostly a plastic powder material (e.g. polyamide, polycarbonate, etc.). During the SLS process, the powder particles are selectively melted together by means of a laser beam. The standard Sinterstation is equipped with a 50 W CO2 laser. The laser energy needed to melt this powder is kept low by maintaining the powder material in the machine on a constant temperature just below the melting point. The processing chamber is continuously flushed with nitrogen to avoid oxidation of the hot powder. The SLS technology is mainly used to build prototypes. It is therefore often classified as a rapid prototyping process.

Modified Perkin Elmer DSC 7
Calorimetry relates the measurement of heat (exotherm) to a physical or chemical process. The photo-DSC measures heat evolution during photo-induced polymerizations and reactions as a function of reaction time. The exotherm of polymerization is proportional to polymerization rate and the area under exotherm curve corresponds to conversion of polymerization. This instrument is a Perkin-Elmer DSC7 modified with a shuttered medium-pressure mercury lamp.

TA Instruments Q100 DSC
The Q100 is a versatile research grade DSC, with patent pending TzeroT technology. The Q100 is an expandable module, to which Modulated® DSC, a 50-position intelligent autosampler, and digital mass flow controllers equipped with automatic gas switching capability, can be readily added. The Q100 can be used over the temperature range -180 to 725°C, and offers a wide variety of available high performance accessories.
MDSC offers all the benefits of standard DSC, overcomes its limitations, and provides further information for greater understanding of material properties. Specifically, it permits separation of the total heat flow signal into its thermodynamic (heat capacity) and kinetic components. It offers simultaneous improvements in sensitivity and resolution, and can separate overlapping events that are difficult or impossible to do by standard DSC. TA Instruments patented MDSC® technology extends DSC to provide the following:
- Increased sensitivity for weak transitions
- Simultaneous optimization of sensitivity and resolution
- Improved capability for interpretation of complex transitions
- Direct measurement of heat capacity.
Advanced Tzero. technology included in the Q1000, makes MDSC experiments both faster and the results more accurate. Heating rates equivalent to those commonly used in standard DSC (10°C / min) are now possible.

Perkin Elmer Instruments Diamond DSC
The DSC actually consists of two separate furnaces for the sample and the reference sides. The system can be divided into two control loops, the average temperature loop and the differential temperature loop. The average temperature loop ensures that the sample and reference sides are heating at the programmed rate. The differential temperature loop maintains identical temperatures between the reference and sample pans regardless of the different amount of heat needed to enter the sample side. This process ensures that the sample is always kept at the same temperature of the reference regardless of any changes that occur within the sample requiring more or less heat flow. When an endothermic process occurs such as softening or melting, more heat is added to the sample side relative to the reference to make up for a difference in temperature. With an exothermic process less heat is added to the sample relative to the reference side.

TA Instruments TGA Q500
The Q500 is a top-of-the-line research grade thermogravimetric analyzer. Its efficient low mass furnace, ultra-reliable thermobalance, unique purge gas system (with mass flow control), and advanced automation provide for superior TGA performance. The Q500 offers the highest sensitivity (0.1mg), with very low baseline drift over the temperature range from ambient to 1,000°C. Sample pan loading and furnace movement are totally automated, and the touch screen data display of operating parameters makes for increased user convenience.
The TGA Autosampler is a programmable multi-position sample tray accessory for the Q500. It allows the routine unattended analysis of up to 16 samples but can be programmed for up to 64 samples. The sample trays are easily mounted and dismounted from the Q500. In addition to increased productivity, the autosampler has flexibility sufficient to satisfy the experimental requirements of both analytical and QC laboratories Optimum performance from the TGA Autosampler is achieved when paired with the latest Thermal Advantage. Autoanalysis software, which permits data analysis routines to be pre-programmed for operation in a sequenced or random fashion.
High precision TGA experiments require constant purge gas flow rates. Control of the flow rate is especially important with high conductivity gases such as helium. Mass flow controllers with integrated gas switching capability provide this control as part of an individual programmed method. Purge gas flow rates are settable from 0 to 240 mL / min in increments of 1 mL / min. The system is pre-calibrated for helium, nitrogen, air and oxygen, and calibration factors may be entered for other non-corrosive gases.

Perkin Elmer TGA
This Thermo-Gravimetric Analyzer (TGA) made by Perkin Elmer measures the weight loss of a sample as a function of temperature. This is done by placing a sample into a sample holder that hangs from a micro-gram balance during the entire experiment. The balance mechanism consists of a sample pan holder suspended by a long hang down wire. The hang down wire is connected to the balance lever by a small quartz link to prevent static build up. The weight of the sample holder configuration is electromagnetically balanced on the other side so that the balance can be zeroed before each run.

TA 2990 Micro-Thermal Analyzer
TA Instruments open a new dimension in materials analysis with the first commercial micro-thermal analyser. The µTA 2990 acts as both an atomic force microscope, imaging the sample surface to high resolution, and a miniature thermal analyser, performing simultaneous thermomechanical analysis and modulated differential thermal analysis on a microscopic scale. Measurements, in programmed heating or isothermal modes, can be made over a broad temperature range (-70 to 500°C), whilst high heating rates enable rapid characterisation. The µTA 2990 maps thermal conductivity, diffusivity and expansion, transition temperatures and visco-elasticity. Used for Surface Visualization, Surface Characterization, Spatial Distribution of Phases, Thermal Properties of small samples/small areas). The probe is moved to the first point selected and placed on the surface of the sample. The temperature of the tip is then ramped linearly with time. The probe is used in conjunction with a reference probe in a way that is very similar to conventional Differential Thermal analysis; thus a 'calorimetric' signal can be obtained. At the same time the degree of bending of the cantilever is measured thus, as the material beneath the tip softens and the probe penetrates into the sample, this provides the micro equivalent of a thermo-mechanical analysis experiment.
