Actus SP Columns

Prepacked preparative HPLC columns with spring-assisted axial compression technology

Prepacked YMC-Actus SP columns are an ideal alternative to DAC columns when lab space, packing capabilities, or financial resources are limited. Spring-assisted axial compression technology eliminates voids in the packing material for accurate, reproducible results. Since columns packed by YMC are QC tested prior to shipping, they’ll arrive at your lab ready for use.

YMC’s Actus SP columns are ideal for oligonucleotide desalting and highly potent, toxic, or radioactive projects. Hazardous compounds often require dedicated systems and hardware, rendering traditional DAC columns impractical. Prepacked Actus SP columns eliminate the need to spend time and resources ensuring that a column has been sufficiently cleaned, packed, and validated for re-use.
