It means slicing off a portion of the stopper located on top of vials.
Needle coring is a process of extracting cylindrical samples of earth or rock from the ground using a hollow tube or needle-like tool. This method is commonly used in construction, geotechnical engineering, and environmental assessments to obtain samples for analysis.
A hypotonic needle is a needle that is a non coring needle. A hypertonic needle is a coring needle. Both of these needles are used in IV's with a hypotonic needle used for hypotonic solutions.
the needle is not correctly inserted into the vial
Inserts a needle at the wrong angle or uses a large-bore needle
That which cores; an instrument for coring fruit; as, an apple corer.
Yes, a non-coring (Huber) needle is the only type of needle that would be or should be used to access a port. the needle is hollow inside and does not remove the flesh that it passes thru when pushed thru the skin. Otherwise the skin plug would block the flow of fluids and regardless you don't want to remove any skin or any portion of the septum (plastic lid of the port) that the needle passes thru.

Non-coring needles are used to puncture through silicone or rubber while not removing any of the material in the process. For example if a regular needle was used to access a port it would damage the port septum (think pushing a straw through a potato) and cause the port to leak. A catheter connects the port to a vein. The septum is made of a special self-sealing silicone rubber; it can be punctured hundreds of times before it weakens significantly. It is used to administer treatment or to withdraw blood. See link:

The needle clamp is collar and screw device that holds the needle to the needle bar. The needle bar is the part that goes up and down as the machine sews and is in front of the pressed foot bar.
a coring to my research he is 36.
One definition of coring is the removing of the central part of a fruit. It is removing the seeds of a fruit. Coring is also the process used to remove a cylindrical sample from rock or soil.
