Environmental Chambers

The polymers and elastomers have to bear a lot of pressure due to their extended exposure to open environments. The environmental factors such as pollution, dust, moisture, Ultraviolet, heat etc. have a bad effect on the quality and durability of the products. The manufacturers have a great challenge to make their products enduring enough so that they could withstand these effects in a better way so that their products could last long and perform in a superior way in actual working condition. To enhance the quality of the products, first, the manufacturers need to test the effects of the environmental factors on the properties of the products and materials so that they can make essential changes to the manufacturing processes to enhance the quality of the products. The Benchtop UV accelerated weathering tester is an ideal instrument for quick, easy assessment of the effects of weathering on the quality of the products. It is an effective and simple testing instrument which can easily replicate the actual working conditions to which the products are subjected to give an idea what would change in their properties. The instrument is a must-have in any industry where polymeric or elastomeric products are manufactured.

Laboratory fume hoods are designed to protect laboratory personnel by preventing contaminants such as chemical vapors, dust, mists and fumes from escaping into the laboratory environment. Laboratory fume hoods also provide lab personnel with a physical barrier to chemicals and their reactions. Fume hoods are evaluated each year to verify their proper operation. They are generally set back against the walls to cover up the exhaust ductwork. Because of their shape, they are generally dim inside but have a provision for a light source. The front opening is made up of glass, able to move up and down on a counterbalance mechanism.

The accelerated weathering test provides two sources of lights namely Xenon lamp and Fluorescent UV lamp. Fluorescent UV lamps are used to create the ultraviolet part of full sunshine; hence it is comparatively difficult to get the reliable testing results all the time when samples are exposed. Additionally, the xenon lamps are used to evaluate the actual life of the polymers as these lamps offer higher feasibility. These lamps are completely filled with Xenon and send the lights because of xenon discharge. A xenon lamp offers stable spectrum distribution and provides an output in the form of steady light energy.
