19743 Qiafilter Midi Cartidges (25)

The 19743 QIAfilter Midi Cartridges (25) from Qiagen are designed for efficient and rapid clearing of bacterial lysates during plasmid DNA purification. These cartridges enable easy filtration of lysates to remove cellular debris, reducing the risk of clogging and ensuring high-quality plasmid DNA yields. Each kit contains 25 cartridges compatible with Qiagens midi-scale plasmid preparation protocols.

The QIAfilter Midi Cartridges streamline the purification process by eliminating the need for centrifugation, saving time and minimizing sample loss. The filtration process is simple: after lysis and neutralization, the lysate is poured into the cartridge, where gravity flow efficiently clears impurities. This results in a clear lysate that can be directly loaded onto Qiagen anion-exchange columns for DNA binding and purification.

Ideal for molecular biology and research laboratories, the QIAfilter Midi Cartridges increase productivity and reproducibility while maintaining high-quality plasmid DNA suitable for downstream applications like cloning and transfection.
