Drawing up needles are designed to draw fluid out of ampoules or bottles, once the liquid is in the syringe, the drawing up needle should be taken off, and replaced with a hypodermic needle.
How do you prevent needle coring?
There is a longstanding recommended technique of needle insertion into a medication vial that reduces the risk of coring (5,6). The needle should be inserted at a 45–60° angle with the opening of the needle tip facing up (i.e., away from the stopper).
Can I reuse syringe with new needle?
Both needle and syringe must be discarded once they have been used. It is not safe to change the needle and reuse the syringe – this practice can transmit disease. A single-use vial is a bottle of liquid medication that is given to a patient through a needle and syringe.
How long can a multidose vial be used?

What is the use of vial?
A vial (also known as a phial or flacon) is a small glass or plastic vessel or bottle, often used to store medication as liquids, powders or capsules. They can also be used as scientific sample vessels; for instance, in autosampler devices in analytical chromatography.
How many times can you puncture a vial?
3. How many times may individual single-dose or single-use vials be entered for a single patient? The safest practice is to enter a single-dose or single-use vial only once so as to prevent inadvertent contamination of the vial and infection transmission.

With the tip of the needle in the liquid, pull back on the plunger to get the right dose of heparin into the syringe.
Why is it hard to push the syringe?
Because the air cannot escape from inside the syringe, when you then try to push in the plunger, the air inside the plunger is compressed into a smaller volume. This higher pressure pushes outwards against the plunger, which is why it becomes much harder to push the plunger further into the syringe.
Why do you put air into a vial of insulin?
So how much air do you inject? About the same amount as the dose you need to withdraw. The air will displace the insulin in the vial. When you shoot the air into the vial, you raise the pressure inside it, making it easier to draw out the contents.
