Analytical Prep Hardware

     To decrease leakage we have designed the frit cap out of Stainless Steel. This eliminates points of bending or bowing, allowing for much higher pressures (15,000+ psi). The cap also has a engineered flow path incorporated to increase dispersion and encourage even loading.We also offer adapting and packing harware for all Prep columns.

   With superior machining and excellent finishes SMS inc's Prep Hardware is the best approach.
