Product Details:

The fingerprint testing chambers from Weiber are designed to accelerate ninhydrin, DFO, and other fingerprint development processes for faster detection of fingerprints. They provide optimum conditions of high temperature and high relative humidity for accelerated fingerprint development processes, while maintaining astonishing clarity and higher throughput. Unlike the conventional methods that may even require days before processing of results, the Weiber Finger Print Development Chamber are capable of processing fingerprints quite rapidly and the results can be obtained within a few minutes. These equipments offer a wide temperature and humidity range and use microprocessor based controllers for highly precise control of operating parameters for highly accurate and stable working conditions, ensuring reliable and repeatable results. The unit ideally operates at 80°C and 65% RH for fingerprint detection using ninhydrin and at 100°C for detection using DFO. Both ninhydrin and DFO work by reacting with the amino acids present in the fingerprints and are commonly employed for fingerprint detection on porous surfaces such as unpainted wood and paper.

Quality of samples preparations for chromosome analysis depends largely on the environmental conditions in which the final evaporation of the methyl acetate or ethyl acetate fixative takes place. The combined effects of temperature and relative humidity have a noticeable effect on the quality of the metaphase.

Product Details:

The Uv Weather Resistant Test Chamber from Weiber are specially designed equipments that are used for the testing of a wide variety of materials including rubber, organic compounds, and non-ferrous materials, plastic and building materials for their ageing and corrosion resistance towards UV irradiation. These test chambers are designed to provide natural weathering conditions by simulating complete UV spectrum that ranges from 280-400 nanometres. This UV spectrum includes the most aggressive UV-B range comprising of very short wavelengths ranging from 280-315 nm that are notorious for causing maximum material damage. The UV radiations can cause significant degradation effects in polymer based materials, ranging from simple discolouration of surfaces to extensive mechanical damage. Surface discolouration severely affects the aesthetic appeal of the product, but mechanical damage can threaten the structural integrity of building materials and the performance of the building product over a period of time

The effect of UV radiation can be frequently observed in the affected materials in the form of surface discolorations, erosion and fading of surfaces, commonly known as chalking and surface cracks. Themechanical damage is generally not visible through the surfaces and manifests itself in the form of changes in tensile strength, elongation in break and other physic-chemical properties. The Uv Weather Resistant Test Chamber play a significant role in determining the stability and resistance of polymers, composite materials and other protective materials in the presence of UV rays and their appropriate usage.
