The use of ultrafiltration membranes for concentration and purification of proteins and DNA is ubiquitous in biological laboratories. Filter devices with ultrafiltration membranes can also be used for concentration of other macromolecules such as inorganic polymers, nanoparticles or even viruses. Although performing sample concentration and buffer exchange using an ultrafiltration device is relatively simple, some tricks of the trade can improve your recovery or speed up your workflow considerably.

 In this eBook you will learn: 

• How to choose the optimal device and method for laboratory ultrafiltration
• Experimental applications for laboratory ultrafiltration
• How to choose the optimal housing and membrane material for your application
• Answers to frequently asked laboratory filtration questions
