The PEEK columns can be used for short-term packing at pressures up to 500 bar (see packing protocol) and 300–350 bar under normal long-term operating conditions. 

You can use the columns at temperatures up to 150–200 °C, but the maximum recommended operating pressure will be lower at elevated temperatures. In this temperature range, we recommend not exceeding 50–75 bar.

It is reported that using PEEK at elevated temperatures for any extended period of time could permanently alter PEEK material making it less stable. Caution is recommended.

Also please note to use only solvents which are PEEK-compatible (i.e. will not extract or soften PEEK).
