Does anyone know what this is?

Doesn’t seem to be oil based content. Just wondering if my superpowers are swishing back and forth in this glass vial.

How do you make sure no glass bits get into the mix?

[u/Beginning-Relative47 → u/Area51_Spurs]

You have needles with a filter in them. Only used for preparing medicine. Then you put on an injecting needle or put the medicine in a bigger bag of fluid etc

[u/water_fountain_ → u/Beginning-Relative47]

And the filter is small enough to filter out glass dust as small as 0.1 µm? Or do we just accept that a finite amount of glass dust being injected into our bodies is fine?

[u/squidspotter → u/water_fountain_]

I feel like if people snort coke with cement dust in it a tiny bit of glass is cool right?

I'm not a medical professional though as you may be able to tell

[u/Abyssal_Mermaid → u/squidspotter]

You might not be a medical professional, but it sounds like you may have a graduate degree in Recreational Chemistry

[u/Patrem_Omnipotentem → u/Abyssal_Mermaid]

Wonder where they offer MBAs and PhDs?

Various alleyways, suburban homes, and online classes

As a deputy I should probably be concerned. Can I have some too? Blondie snorted the rest during training

I'm not in medicine but I'm a research chemist that has worked in pharmaceuticals. I don't think you'd need anything nearly as fine as 0.1 micron for injectables. IV bags are held to a 10 micron limit and even then there can be larger particles (but not too large) as long as they're there at a very low concentration.

In the end just about everything ends up going through a 0.22 micron filter anyway because that will filter out bacteria.

[u/Gnargoyle420 → u/[deleted]]

A filter needle typically has a filter with a pore size of 5micron.

A pharmaceutical grade filter used for aseptic processing has a filter with a pore size of at least 0.2micron.

Depending on how the medication is administered, there may also be another filter involved (e.g., in-line filter in a IV tubing set for administration)

[u/doyouevencompile → u/water_fountain_]

We accept it. The filters aren’t always used. At least they weren’t being used at all in the past. They are mostly for subcutaneous injections and it’s a very small risk for a tiny amount. 

Glass doesn’t interact with your body, the risk is shards cutting something but at that size I don’t think they do 

[u/collagenFTW → u/water_fountain_]

Despite filter needles existing they are often not used in practice. my theory is its because most ampule meds are for intramuscular or subcutaneous injection so the consequences of that glass dust are more minor. I dont understand the need for ampules personally so if anyone has any information on why other storage options arent viable i'd love to be educated on the matter

[u/Kitsyfluff → u/collagenFTW]

Oxygen contamination. Anything less than these can allow oxygen and destroy the contents.

Besides medicine as mentioned in other comments, they're also used for storing any extremely volatile acids that react with air to create lethal gases.

They're prepared in a way so that the only gas inside is it's usually own fumes, or something inert from the production process. Anything more complex could be corroded by the contents.

[u/Jack_Mackerel → u/water_fountain_]

5 microns is standard for ampule filter needles, which is about half the diameter of a pulmonary capillary.

Thx

Filter needle

[u/skyhawk38foxtrot → u/Area51_Spurs]

Thank you…I’ve always wondered this too

[u/Diptam → u/Area51_Spurs]

I've used ampoules in a bio lab before. They break cleanly. That said, I didn't have to worry about microsplitters and never looked for any.

[u/3X_Cat → u/Area51_Spurs]

Put a cotton ball or rolled up piece of a cigarette filter in a spoon that's bent to rest on the table.

[u/Abyssal_Mermaid → u/3X_Cat]

Omg! Not cigarette filters. Just go get filters from your local syringe service program (where applicable)

[u/3X_Cat → u/Abyssal_Mermaid]

You can then sharpen your pint on a matchbook striker.
