FPLC Reagent Caps - GL45 Schotts Bottle

Here is my version 1 GL45 thread bottle cap for FPLC (Cytiva) reagents. It has two parts, the first is the open-top screw cap that sits on the bottle and the other is the cap cover with slit for the tubing to fit through. I got sick of have foil squares that would get dirty, go missing, fall off or have holes when covering my reagent bottles on top of my Cytiva and quickly designed this.

I hope it helps others.
