F&S Scientific consumables with unique features make everyday routines faster, easier, and more reliable. Due to the avoidance of any slip agents, plasticizers, and biocides during manufacturing, the risk of chemical leaching into the sample is minimized. The availability of different purity grades is tailored to the various requirements in laboratories.
F&S Scientific offers a wide range of high-quality, durable and dependable temperature control and mixing instruments to cover all requirements. 50 years of experience in the field of mixing and temperature control, and continuous further development, have made their mark in this generation of products.
The use of UV transilluminators for the detection of DNA or RNA in agarose gels, is still very common, although we know quite well that the shorter the wavelength is, the more the DNA will be damaged quickly, which is dangerous especially if the separated DNA should be used in downstream experiments like cloning or sequencing. Just seconds of UV light is enough to reduce the cloning efficiency significantly.
In contrast to UV instruments, the new innovative LED technology uses a much higher wavelength, which means energy-less light. This will lead to the fact that the nucleic acids are not damaged but sometimes sensitivity is lower as compared to UV light. Furthermore, regular BLUE LED technology is working well with green dyes but couldn’t be recommended with red dyes like Ethidium Bromide, because the longer wavelength is favourable for green dyes but not for red components.
