BioMaths is a simple application that performs a number of common calculations needed while working as a biological bench scientist. Currently, the functions are split in to a number of sections. With time I hope to expand the number calculations, so if you have any ideas feel free to e-mail your suggestions. At the moment the application has these sections: PCR, radioactivity, OD, Making solutions, Sequence and Centrifugation. At the bottom of each page is a short description, describing how to perform the calculation. I hope you find the application useful and to make up for poor spelling and grammar, its advert free!
