After I fill these syringes through the tip and capping, the caps can be hard to unscrew. It seems that there is a small bit of oil on the tip post fill and that oil rubs against the rubber of the cap making it hard to put on and pull off.
Are people cleaning the tips? Am I missing a step? Do they replace with a different cap?
Im not sure how/what ypur using to fill or how many but maybe instead of unscrewing luer lock just pull whole lpck off and fill like that if possible? Maybe clean tip with iso pad if needed? Just some ideas
When i filled mine i top filled with just syringes and warm distillate and just flipped it and then pushed the air out anyway hope you find the answers your looking for!
