Product Information
Particle size of preparative spherical packing material is 10µm, 15µm, 20µm, 50µm, 75µm, and 150µm. Their quality of all sizes of products is strictly controlled. YMC S-50 gel (particle size 50µm) is useful for preparative chromatography because of their moderate particle size and good cost performance.

Product Information
Irregular packing materials for preparative isolation come in a wide variety of particle sizes and are applicable to a wide range of isolations from semi-preparative isolation to industrial preparation.

YMC Co.,Ltd.'s irregular packing materials for preparative isolation have excellent cost performance, and are applicable not only to open column chromatography but also to pretreatment of samples(partial purification and batch treatment for concentration). Among them, silica gel with a particle size of 63 - 210 µm is especially suitable for open column chromatography.
