It means slicing off a portion of the stopper located on top of vials.
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.
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.
Coring can occur when a drilling tool or bit fails to cut through the material being drilled, resulting in a cylindrical piece of material being extracted instead of drill cuttings. This can be caused by equipment malfunction, inadequate drilling fluid properties, or encountering a hard formation.

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.
A Huber needle features a unique design characterized by a non-coring, beveled tip that allows for easier access to implanted ports without damaging the surrounding tissue. It typically has a longer and thicker shaft than standard needles, with a safety feature that can include a retractable design. The needle is often connected to a syringe or infusion set and is usually color-coded based on gauge size for easy identification.
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.
