Brand: Millipore . Mpn: Kvpv04tt3 . Model: Opticap 4 . . Lab The objective of this work was to examine the effects of solution pH and ionic strength on virus retention by the Viresolve ® NFP membrane. Experiments were performed using the bacteriophage fX174 as a model virus, with the virus retention data complemented by the use of confocal microscopy to directly visualize the capture of fluorescently-labeled fX174 within the filter. The Viresolve NFP disk membrane was soaked into Water for Injection (WFI) with the shine side faced up until the membrane layer became uniformly wet.

Optiscale-40 devices with Viresolve prefilters (5.0 cm 2) were also purchased. Results for the Viresolve® Pro membranes showed much greater pore interconnectivity than for the Viresolve® NFP membranes. SEM images of the Ultipor® DV20 membrane showed nanoparticle capture only at regions of the inlet located directly over the open portions of the membrane exit, indicating that there is minimal lateral flow in this membrane. Viresolve NFP (normal flow parvovirus) membranes from Millipore are high-flux composite membranes that use a size-exclusion mechanism to achieve a greater than four-log removal of parvoviruses.

Merck’s product portfolio includes a vast range of filters and single-use systems, comprising Viresolve Prefilter Pod Disposable Devices, Viresolve NFP Cartridge Filters etc. Over the past three years, the company adopted the strategy of new product launches and acquisitions to maintain its leadership position in the global virus filtration market. 2010-01-14 2014-09-07 Description.

Lab Experiments were performed with Ultipor® DV20, Viresolve® Pro, and Viresolve® NFP membranes using bacteriophage φx174 as a model virus. The filters were challenged with two batches of fluorescently-labeled phage: one labeled with red dye (Cy5) and one with green dye (SYBR Gold) to visualize captured phage from before and after the pressure release.
