Push Drop out Tip to Prevent Blockage
Once syringe is full of morphine liquid up too 100 unit line, it is ready to cool.
Again, push a little drop out the needle tip to ensure all it clear and there is no blockage. Wipe drop with kleenex.
All liquid within the syringe should be clear and with very semi-solid bits that can harden into chunks.
If you hold needle up to a light, liquid inside should appear quite clear through and through, from top to bottom.
