Muffle furnaces

Function and use:

Muffle furnaces are suitable for laboratory testing in which exact temperature distribution, controlled increase and decrease of temperature, and controlled cooling are important, and where it is also desirable that the heating elements are not in the interior space with the samples. These include heating of material for heat treatment of metals, various sintering tests, calcination, determination of the softening or sintering point of materials, burning of samples, firing of enamels, etc. The stainless steel casing ensures a long service life of the furnace, the heating spirals are housed in quartz glass tubes – the spirals are thus partially protected against attack by aggressive substances that can be released from the charge. The programmable controller and the main switch are located on the front of the furnace.

Function and use:

Cold isostatic pressing is a method of processing materials. The principle is popularly known as Pascal’s law and it states that pressure applied in an enclosed fluid is transmitted in all directions throughout the fluid without any change in the magnitude of the pressure. Cold isostatic pressing involves compacting powders by enclosing them in an elastomer mold. An elastomer mold is used because it has low resistance to deformation. Liquid pressure is then applied uniformly to the mold to compress it. At the end of the process, you are left with a highly compact solid. CIP can be used for plastics, graphite, powdered metallurgy, ceramics, sputtering targets and other materials.

The Quatro controller has four circuits controlling the sample temperature, the gas temperature, the temperature of the liquid nitrogen in the dewar and the pressure in the dewar. In addition the vacuum pressure is measured. This design allows a very fast, precise and safe operation, which is required for automatically driven systems. Even if sensors would fail or the liquid nitrogen dewar becomes empty, the system will automatically shut down in order to protect itself and the sample.

Equipment for coating of solutions and suspensions by spray technology
Function and use:
The spray coater is a multifunctional industrial instrument employed for the purpose of depositing a uniform and thin film of liquid or suspension onto a given surface. The ND-SP-Precision Spray Coater operates by applying pressure to the material, causing it to atomize into small droplets or particles. These particles are subsequently dispersed over the desired substrate by a spraying mechanism. These mechanisms guarantee consistent distribution, accurate regulation of thickness, and effective utilisation of materials. The temperature of the substrate bed can be controlled up to a maximum of 250 degrees Celsius.
