Absolutely. I can do them in different beakers. Do we still want 100%BB test and a 80/20%BB test?

Awesome. Nevermind. You beat me to it.Alright, 2/20.
How do you guys even take pictures of this?
Light just gets reflected off

Light background in a darker room like in a window with the lights off allows me to take decent pictures.

NiPro 1ml is gone.
Wonder how many hours before the rubber falls off lol
It's turning my solution cloudy.
Which do you think will last the longest?

ooooookay, so no more prefilling a week’s worth of syringes. That’s in 2/20?NiPro 1ml is gone.

Doubt they will last the night.
Think the NiPro 3mls died first followed by the insulin syringe.

Really cloudy..cant see much.
Should i stir it?
Makes me wonder if the cloudy shit you see in some vials are simply just..melted plastic or rubber.

It totally looks like plastic. I the first picture you posted that was zoomed in, it looked like the white plastic part was reacting to the chemical and diffusing. I think you'll have to pull it out, compare it to a newer stopper and look at the stopper to see if there is any breakdown.

I agree with that, it does look the plastic melted first. It's probably a much weaker plastic than the spikes you have.
Good call. Just pull the plungers (black part) off so only the material that comes into contact with gear is tested. The white shaft never touches the gear. The syringe shell is polypropylene i believe. Test it?

I'm not so worried about polypropylene.
BA is much stronger in dissolving plastic.
It gives BA an A rating, so I'd expect it to handle BB fine.

What plastic does the middle piece use tho..
The entire solution looks like milk now..i'll take a closer look when i get home..

Alright, ending my experiment because the entire 2/20 solution is so milky i cant see anything.
Comments
1) NiPro 1ml -- Plastic melted the most, like 1/2 of it melted away. Minor swelling in rubber stopper. Plastic was first to melt.
2) ClearTouch insulin syringe -- Rubber stopper swelled the most, i don't even think it can fit into the syringe anymore.
3) CarePoint 5ml & NiPro 3ml - Minor swelling in rubber stopper, no visible signs of plastic degradation, but it did produce white cloudy substances in the solution similar to when AAS crashes in oil.
The key thing to remember is that none of these were designed to be soaked in BA/BB solution or backfilled and left for days/hours. Nurses/doctors load up the syringe and pin immediately.

There’s a possibility that the cloudy shit in some cases is silicone oil.

On the 100%BB, the tip finally fell off over night. This was not from me acctuating it.
It looks like there could be a hole in the housing now. Either this area is the only area that isn't cloudy ot there is a hole in the housing. I can't tell unless I go in there and poke it:
The thickness of the satilite dish is almost 100% gone. Compare the thickness to the other previous photos or the photos from the 80/20. This one is interesting because it seemed as the white, cloudy area was the part that was degrading and the clear parts were not. Made me think that there was a certian plastic that reacted heavily with the BB but, here you can see that even tho this clear satilite dish was not mostly white/corrded, it still has been disintegrating:
As for the 80/20, it actually looks really good. I don't see any signs of anything new as far as I can tell. Doesn't mean something isn't happening, it just isnt visible to us yet:
The tip isn't more bent than previous pictures:
This might be some corrosion, it might be nothing but this is the only visible thing I noticed when looking. This MIGHT be a tiny bit of corrosion starting on the satilite dish but its so small, its hard to tell. I tried to zoom in but my pixel 8 pro is having a tough time getting detail at 5.8x zoom:
Let me know if you guys want more pictures. I think I am going to leave the 100%BB one in there until it is full gone. Would be fun to see how long it takes. I'll leave the 80/20 around for as long as we think we came to a conclusion.

I'm just surprised your solution doesn't turn cloudy.
Mine turned to milk in less than 24 hours.

There really isnt anything in there that is white. I think yours turned cloudy because of the plastic disolved that the plunger was attached to.
I would expect mine to maybe turn a blue tint at some point in time.
It looks like the white plastic is getting damaged the most, however this isn't the portion of the syringe in contact with the fluid inside. How is this a better test than just filling a syringe and leaving it (make sure no air bubble protects the black plunger)?
Having a preloaded syringe stored upwards with an air bubble between the plunger tip and the fluid should prevent the degradation.
Who wants to do another study with filled syringes?
