TMA-60 Series — Thermomechanical Analyzer

Bara Scientific — Thu, 06 Sep 2018 04:44:21 +0000

Achieves high accuracy measurements using simple operations.

The TMA-60 series thermomechanical analyzer accommodates a wide variety of samples and can use various measurement methods* (expansion, elongation, or penetration) to evaluate sample characteristics thoroughly. New functions, such as automatic length measurement and safety features, were incorporated into the development, resulting in high performance, high functionality, and ease of use in many dimensions.

*Model TMA-60 is capable of the total expansion method and Model TMA-60H is capable of the differential expansion method.

In addition, the TMA-60 series is compatible with LabSolutions TA.

Two Available Analyzers – Select in Accordance with the Measurement

TMA-60 Total expansion

Simple to use for a variety of measurements

With the TMA-60, three types of measurement can be performed tension measurement, expansion measurement, and penetration measurement.
The sample support tube and the detection probe can be attached and removed with one touch, so the instrument can be used for diverse forms of measurement, and it can be maintained with ease.

TMA-60H Differential expansion

Can be used for low expansion measurements

With the TMA-60H, differential expansion measurement can be carried out using a reference with a known expansion coefficient, enabling higher accuracy measurement.

Loading modes that can be selected

For More Comfortable Day-to-Day Measurement Work

Automatic analysis using the “Template Function”

Corrections, analysis, and layout setting of reports can be carried out automatically using the unique “Template Function.”
This can be used not only during analysis but also prior to measurement. It will be automatically applied when the measurement is completed and saved.

Fusion bonding prevention mechanism

A safety mechanism is provided to prevent fusion bonding between the measurement rod and the sample when materials such as glass are heated. When the displacement exceeds a set range due to melting of the sample, the analysis is immediately stopped, and the load is removed from the sample.

Can be Used for a Wide Range of Measurements

High accuracy measurement of low expansion materials

A new high-accuracy low-drift displacement sensor has been adopted, dramatically improving measurement accuracy.
Even the low expansion metal Super Invar can be measured.

Large changes can be measured over a wide dynamic range

Measurement can be carried out over a wide span of ±5 mm, with high-accuracy measurements from very small to large deformation.
Samples with large deformation, such as separators in lithium-ion batteries, can be measured.

Film shrinkage stress can be measured

Shrinkage stresses can be measured with high sensitivity and high controllability.

DTG-60 Series — TG/DTA Simultaneous Measuring Instrument

Bara Scientific — Thu, 06 Sep 2018 04:41:46 +0000

TG/DTA Simultaneous Measuring Instrument

This instrument varies the sample temperature in accordance with a program and simultaneously measures the change in mass of the sample (TG) and the temperature difference between the sample and a standard substance (DTA). An analytical balance mechanism (Roberval mechanism) offers high reproducibility and allows worry-free operation even for measuring sample weights. Two models are available for different maximum measurement temperature requirements-the DTG-60 (max. 1,100 °C) and the DTG-60H (max. 1,500 °C). Corresponding DTG-60A and DTG-60AH models with a built-in autosampler are also available to automatically measure up to 24 samples.

High-Sensitivity and High-Accuracy Measurement

High-accuracy Roberval mechanism top-loading balance system

The Roberval mechanism has been adopted, so that the sensitivity does not change due to changes in the center of gravity of the sample caused by melting, etc.

What is the Roberval mechanism?

Regardless of where the sample is placed in the detector pan, the sensitivity of the balance remains constant. The sensitivity does not change due to changes in the center of gravity of the sample caused by melting or expansion due to heating.

With a simple balance, the measurement varies depending on the position in which the sample is placed. There is a possibility that the result will change every measurement, so the reproducibility is low. When the beam is heated in the furnace the distance between the fulcrum and the sample changes due to thermal expansion, so the measurement changes. If the center of gravity of the sample varies during measurement due to melting or expansion caused by heating, then the measurement will change.

On the other hand, the Roberval balance has a parallelogram frame structure with freely moving sides, as shown in Fig. B. If pans are placed on its vertical beams and the sample and weight are placed on top of these pans, they will be balanced regardless of where the sample and weight are placed if their masses are the same. The sample may be placed anywhere on the pan.

Light Fulcrum

The fulcrum is a thin alloy band with a very small temperature coefficient, configured into an X-shape. This fulcrum is lightweight and has very little friction and resistance, enabling the construction of a high-sensitivity balance, which is also very resistant to vibrations.

Supports Various Types of Measurement

Flow channels for reaction gas provided

With TG/DTA measurement, qualitative and quantitative analysis, the study of reaction mechanisms, and evaluation of thermal resistance can be carried out by observation of various types of reactions and interactions between the sample and special atmosphere gases. With the DTG-60 Series, various applications are supported by configuring individual flow channels. There is one gas inlet, so the gas can be led directly to the sample, and time is not required for the reaction.

Wide range of thermogravimetric measurement

The thermogravimetric (TG) measurement range is broad at ±500 mg, with a weighing capacity of 1 g (including tare weight), so it can be used for diverse measurements.

Automated Functions Increase Throughput

The analysis is simple with the automatic analysis function: `Template Function`

Corrections, analysis, and layout setting of reports can be carried out automatically using the unique `Template Function.` This can be used not only during analysis but also prior to measurement. It will be automatically applied when the measurement is completed and saved.

Shorter analysis wait time

The built-in furnace cooling fan starts automatically after the measurement is complete.
Also, it is possible to stop the fan at a predetermined temperature (setting can be varied), so the next measurement can be started immediately.

Software enables easy operation for everything from measurements to data analysis

LabSolutions TA workstation software ensures all steps from measurement and data analysis to report generation can be performed smoothly using intuitive operations. It also allows the instrument operating status to be confirmed at a glance.
Optional software is also available for supporting a variety of specific measurement parameters.

DSC-60 Plus Series — Differential Scanning Calorimeter

Bara Scientific — Thu, 06 Sep 2018 04:38:31 +0000

DSC-60 Plus addresses the various DSC applications.

DSC (Differential Scanning Calorimeter) is an indispensable thermal analyzer for materials characterization in R&D and quality control applications in such areas as polymers, pharmaceuticals, electronic parts , foods , etc . It offers the sensitivity and easy operation required for the development of high-performance, highly functional new materials.

A DSC-60A Plus model with a built-in autosampler is also available for measuring up to 24 samples automatically.

By overlaying temperature-modulated results onto results obtained by increasing the temperature at a constant rate, Temperature Modulated DSC (Option) can easily measure specific heat, or can measure multiple phenomena that could not be separated using standard DSC systems.

Enables high-sensitivity measurements at temperatures ranging from ultra-low to high.

The DSC-60 Plus series achieves a stable baseline throughout its entire measurement temperature range (-140 to 600 °C) and offers the highest DSC sensitivity levels. The series also provides calorimetric measurement over a wide ±150 mW dynamic range.

Enables a wide variety of measurements using simple operations.

DSC-60 Plus series enables easy measurement of samples that need to be measured below room temperature by filling a standard cooling bath with liquid nitrogen.

The sample loading temperature function only heats the region around samples when they are replaced during successive measurements. The temperature is set to allow quick resumption of measurement without moisture condensation.

Temperature Modulated DSC (TM-DSC) (Option)

By overlaying temperature-modulated results onto results obtained by increasing the temperature at a constant rate, TM-DSC can easily measure specific heat, or can measure multiple phenomena that could not be separated using standard DSC systems.　
If glass transitions, enthalpy relaxations, and other reactions overlap, separation is impossible with standard DSC measurements. Using TM-DSC, however, enables separation of these phenomena.

What Is TM-DSC?

This program can control the temperature by overlaying a sinusoidal modulation over a constant temperature increase (or decrease).

Three types of heat flow data can be obtained by post-measurement data analysis.

(1) DSC Signal (Total)
Indicates the total heat flow.
This is the same as the heat flow obtained from standard DSC systems. It is obtained by deleting the modulated component from the data obtained by TM-DSC.

(2) DSC Signal (Reversing)
Indicates the reversing heat flow.
This component of the heat flow tracks the temperature modulation, and is equivalent to measured heat. It is obtained from the modulated component of data obtained by TM-DSC.

(3) DSC Signal (Non-Reversing)
Indicates the non-reversing heat flow.
This is the component of the heat flow that does not track the temperature modulation. It mainly appears for thermal processes that progress spontaneously, such as crystallization, curing, and enthalpy relaxation. It is obtained by subtracting the reversing signal from the total signal.

Software enables easy operation for everything from measurements to data analysis.

LabSolutions TA

Easy-to-use data analysis functionality improves productivity.

Automatic manipulation and automatic analysis functions in template format
Measurement result reports are automatically prepared

When the template function is used, manipulation and analysis can be automatically performed. By configuring the template in the acquisition program prior to measurement, automatic analysis and report preparation can be performed.

Automatic analysis using the “Template Function”

Corrections, analysis, and layout setting of reports can be carried out automatically using the unique “Template Function.” This can be used not only during analysis, but also prior to measurement. It will be automatically applied when measurement is completed, and saved.

Temperature change data can be analyzed with ease

Data on repeated temperature increases and decreases can be treated as independent data using the “Analysis Range Setting Function,” so analysis can be carried out simply. Using this function, data related to repeated temperature increases and decreases can be divided into separate data.
