Linseis Inc. Horizontal Research Dilatometer L75 PT

horizontal Dual- and differential- Dilatometer (DIL) series L75H was developed to meet the demands of the academic community and research laboratories worldwide. With this system, thermal expansion behavior of solids, liquids, powders and pastes for a variety of applications can be precisely determined. The unique design of this system guarantees highest precision, reproducibility and accuracy. This line of Dilatometers is capable of performing measurements under vacuum, oxidizing and reducing atmospheres.

This system can be ordered in a single, dual or differential version for even higher precision or sample throughput. Optionally the mechanical and electronic components of the dilatometer can be separated to allow measurements in a glove box.

With our automatic pressure control, the contact pressure can be continuously varied between 10 and 1000mN, depending on the application. This feature continuously controls the selected contact pressure throughout expansion and/or shrinkage of the sample.

The following physical properties can be measured:

CTE, Linear Thermal Expansion, Alpha Physical, Sintering Temperature, Phase Transformations, Softening Points, Decomposition Temperatures, Glass Transition Temperatures.

The vertical research Dilatometer series L75V was developed to meet the demands of the academic community and research laboratories worldwide. With this system thermal expansion behavior of solids, liquids, powders and pastes for a variety of applications can be precisely determined. The unique vertical design of this system is perfect for low or ultra low expansion materials, since the vertical “Zero-Friction” design guarantees superior measuring results. This line of Dilatometers is capable of performing measurements under vacuum, oxidizing and reducing atmospheres.

This system can be ordered in a single or differential version for even higher precision or sample throughput. Optionally the mechanical and electronic components of the dilatometer can be separated to allow measurements in a glove box.

NEW Cryo Option for Temperatures down to 10 K:

LINSEIS L75 Cryo „Ultra Low Temperature“ series is available in vertical (Zero – Friction) mode of operation. It offers a broad temperature range (-260°C up to +220°C), many different sample holders, operation in vacuum or a controlled oxidizing or reducing atmosphere, while maintaining the highest accuracy and ease of use.

The following physical properties can be measured:

CTE, Linear Thermal Expansion, Alpha Physical, Sintering Temperature, Phase Transformations, Softening Points, Decomposition Temperatures, Glass Transition Temperatures.

The LINSEIS L75 PT Quattro Dilatometer is a very unique instrument, which was developed for customers which have to deal with a large amount of samples. The Quattro Dilatometer is built up with four separate dilatometer measuring sensors, which can measure simultaneously either four separate samples at one time, or three separate samples against a reference standard.

That means, the productivity of the Quattro Dilatometer is three times as high as compared to the normally used dual push rod dilatometers. With a dual push rod dilatometer only one sample can be measured against the standard at each time.

Another feature included in this Quattro Dilatometer is an automatic furnace lift mechanism. This feature automatically lifts the furnace at the end of each measurement without any operator interaction. This allows the user to insert new samples while the furnace is still cooling down, when a second or third furnace is mounted on the system the sample throughput can be even further increased significantly.

The Quattro Dilatometer uses a unique amplifier with automatic zero setting for all four samples. Furthermore there is a “manual push rod speed release” for each sample. With this feature all four samples can easily be changed and seated correctly for high accuracy measurements.

We are proud to say that as far as we know Linseis is the only supplier worldwide, that can offer this highly specialized dilatometer. This is another example of our powerful line of thermal analysis instruments.
