The use of a filter needle is required when drawing up medication or solution from a glass ampule. This allows any glass particles to be filtered out of the solution before using that solution in a patient or final product.
What type of needle do you use with an ampule?
Blunt filter needles or filter straws with a 5 micron filter should be available and used each and every time a medication is aspirated from a glass ampoule to reduce glass particle contamination Such action will promote patient safety and reduce the risk of patient harm.
What size micron needle do you use when removing liquid from an ampule?
/5 Micron
The Blunt Fill Needle & Blunt Fill Needle w/5 Micron Filter are intended to be used in a variety of medical, pharmaceutical and laboratory procedures to extract fluid or medication from vials or ampules for transfer or irrigation.
Why use a filter needle with an ampule?
Why do we need to use a Filter Needle? The ampoule is opened by breaking the neck. This process can cause a shower of miniscule glass shards that may fall undetected into the vial. A filter needle will reduce the chance of glass being introduced into a medication.
What size filter needle should be used when withdrawing the contents of an ampule?
5-µm
The ASHP 2008 guidelines involve the above USP 797 standard and the use of a 5-µm filter needle or straw when drawing medication from a glass ampule. The INS (2011) Standard 28.6 states: “a blunted filter needle or filter straw shall be used when drawing medication from glass ampules” (p. S34).
What size is a filter needle?
In scientific applications, the most common sizes available are 0.2 or 0.22 μm and 0.45 μm pores. These sizes are sufficient for HPLC use. The smallest known sterile syringe microfilter have pore sizes of 0.02 μm. Membrane diameters of 10 mm, 13 mm, 25 mm are common as well.
What is the filter size of a filter needle?
The 18 gauge (1 1/2″) needles include a 5 micron filter to minimize the potential of particulate being dispensed. The special sintered design of the filter retains particles not only on its surface but throughout its sponge-like construction.
What is the difference between 1 micron and 5 micron filter?
The smaller the micron number the better. A 5 micron water filter will sieve out particles that you can see – but all the other smaller particles will pass through it into your drinking water. By contrast a 1 micron filter will remove particles not visible to the naked eye.
Which needle size is commonly used by sterile compounding personnel?
An 18-gauge needle is most com- monly utilized for sterile compounding. Needle gauge is also a factor when administering CSPs.
Which is bigger 1 micron or 5 micron?
What is a difference between filter needles and vented needles?
Filter needles are molded into the hub of the needle and are designed for one-time use only. They remove glass shards that may contaminate a solution when using a glass ampule. Vented needles are used primarily for reconstituting a powdered medication.
Do you use filter needles with ampoules?
Filter needle use with ampoules can reduce the risk of GPC Pharmacy and nursing have established standards of practice to improve patient safety by reducing GPC when drawing medications from ampoules Some Anesthesia professionals that regularly use ampoules do not routinely use filter needles when preparing medications…
Are blunt filter needles and filter straws necessary?
Blunt filter needles or filter straws with a 5 micron filter should be available and used each and every time a medication is aspirated from a glass ampoule to reduce glass particle contamination Such action will promote patient safety and reduce the risk of patient harm.

Does injection of glass ampules cause glass particle contamination?
There have been many studies on glass particle contamination from glass ampules during the injection of glass ampules, but only the contamination from direct IV bolus injection has been measured.
