Ultrafiltration is a convective process using anisotropic semi-permeable membranes to separate macromolecular species and solvents – primarily on the basis of size. By allowing solvents and salts to pass the ultrafiltration membrane while macromolecules are hindered to pass it, they are being concentrated. However, ultrafiltration can also be applied in solvent exchange applications. Multiple concentration and refilling steps will progressively lead to a buffer exchange, replacing lengthy techniques like d ­ ialysis. Although ultrafiltration is not a standard method for separating and...

p ­ roviding process times that are typically 30 to 50 percent faster than c ­ entrifugation. You can use Vivaspin® 20 and Vivacell® 70 for pressure-­ fugation (5 to 50 ml starting volumes). – Crossflow (Tangential Flow) (100 ml to 5l Starting Volumes) The sample is pumped across an ultrafiltration membrane and then returned to the original reservoir by building up pressure at the outlet of the device. The solution is progressively concentrated as solvent and micro-molecules pass through the membrane into a separate filtrate vessel. Reusable Vivaflow® 50R and Vivaflow® 200, as well as...

Protein Concentration Vivaspin® 500 100 µl to 500 µl Samples Vivaspin® 500 µl centrifugal filter units offer a simple, one-step procedure for sample preparation. They can effectively be used in fixed-angle rotors accepting 2.2 ml ­centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990) minimizes membrane fouling and provides high-speed c ­ oncentrations – even with particle-laden solutions. Specifications Vivaspin® 500 Concentrator capacity Dimensions Swing-bucket rotor Fixed-angle rotor Total length Width Active membrane area Hold-up...

Protein Concentration Vivaspin® 2 Choice of Membranes 0.4 ml to 2 ml Samples The Vivaspin® 2 bridges the gap between the 500 µl and 4 ml centrifugal c ­ oncentrators. This device combines the speed of the classic Vivaspin® products with low internal surface and membrane area for superior recoveries from very dilute solutions. Also unique to the Vivaspin® 2 is the choice of directly pipetting the concentrate from the dead-stop pocket built into the bottom of the concentrator or alternatively reverse spinning into the concentrate recovery cap, which can then be sealed for storage. Both...

Protein Concentration Centrisart® I Centrisart® I* is a ready-to-use unit for small-volume, centrifugal ultrafiltration to separate proteins from low molecular weight substances in biological samples. ® Centrisart I features a unique design that enables ultrafiltration in the direction opposite to centrifugal force. This is so effective in preventing premature blockage of the filter that even whole blood samples can be deproteinized. The ultrafiltrate is collected in the floater insert tube, where it is readily accessible without removing the tube. Centrisart® I is ideal for the following...
