1. Affix the endcaps on the liner with acetone. It To avoid potential organic contamination of samples, it is important to ensure all sampling on the catwalk has been completed before doing so.
2. After you have finished processing the CC, measure the length of the final core catcher on the ruler. Give the total length of the core catcher and length of the PAL sample to the Curator or ALO. It is important that this is be an accurate measurement!

Example: For a CC that is 15 cm total length with a 5 cm PAL sample say, "Fifteen with five to PAL" or "Fifteen and five to PAL."

1. Clean the CC section before handing it off to the core lab. Clean the core catcher bench and tools. Be sure to keep the bench stocked with usable core liner. If running low cut new pieces and stock on shelf below CC bench.

Arbor Press

If the Core Catcher material is difficult to manually push out from the core catcher, use the Arbor Press (see Figures 4 and 5). There are two different jigs that can be used to assist with the pushing. One for APC (Figure 6) and one for XCB (one for lower bit; figures 7). Lubricate the moving parts of the arbor press with Lubriplate, or a mixture of Lubriplate and Marvel Mystery Oil.
