Durable The Vacu-Blot is an intelligent device that can save a lot of time in the blotting method. What used to take about 12 hours or so can now be completed within 15-60 minutes, depending on the DNA size. The earlier method of blotting, the process of transferring molecules onto the surface of the membrane was done through capillary blotting. The Vacu-Blot allows vacuum blotting, making it an efficient method for protein sequencing for subsequent analysis. The device is made of acrylic ensuring its durability, reliability and efficiency. A sealing system allows for fast transfer, the large tank allows for easy recycling of buffer eliminating the need for a separator or trapping bottle
