In the process of separating and purifying compounds, preparative columns that have high efficiency, stability and low pressure play a crucial role in developing a reliable separation and purification technique.

Welch Materials, as a competitive manufacturer in this industry, released WelFlash SiO₂ LS column to help your separation and purification work.

WelFlash SiO₂ LS

Special personality

The new generation of WelFlash SiO₂ LS column is your best choice for separation and purification because it has characteristics of high pressure resistance, excellent column efficiency and corrosion resistance. The properties and parameters of each batch of WelFlash SiO₂ LS preparation columns are precisely controlled and rigorously tested to ensure high recovery rate and good batch to batch reproducibility.

WelFlash SiO2 LS medium and low pressure preparation column packed with high quality silicone with well-balanced price and performance.
