O-rings and nets should be checked regularly for wear. Worn O-rings may not seal properly and over-used nets can affect distribution. Inspect the O-rings and evaluate the height equivalent to a theoretical plate (HETP) and peak asymmetry factor (A_s) to prevent poor performance due to old nets. We recommend you to change the nets and O-rings when needed or at least annually. Please keep a set of each on your site, for code numbers refer to the table below.

23 µm nets are supplied with the column and recommended for beads with an average particle diameter between > 70 µm. For an average particle diameter < 70 µm use 10µm nets.
