To better serve our customers, Onfocus created microscopy and centrifugation resources. The main reason is the flexibility of the publication platform. The orginal support website is based on Joomla. The publication of Joomla article is based on session -> category -> article. We want to provide our customers a more flexible way of organization information. This will allow you to locate information easier. As we know that the biological taxonomy system is hierarchial. They don't fit into the session/category/article model.
