вот контекст:

For each sample remove one Spin Column Assembly from the plastic tray by gently pushing the tube through the paper. Each Spin Column Assembly consists of a Spin Basket and a Collection Tube. If you do not need the caps on the Spin Baskets simply remove them using a twisting motion; the caps are designed to detach from the Spin Baskets. If the caps are left attached to the Spin Baskets,
they must be closed during centrifugation steps. Label the Collection Tube and place the Spin Column Assembly in a microcentrifuge tube rack. It is important to label your tubes to maintain sample identity. Wear gloves when handling the tubes.

спасибо!
