I haven't had it happen with any of my stoppers for vials but I got a butyl stopper for a glass media jar I use for filtering my brew and it has happened with that.

Yeah ive had it happen to others as well. But again ive only experienced this when using 18g, never occurs when using 21g or smaller. I guess Organon and Pfizer should close down. They apparently do not know how to manufacture a multi-dose rubber stopper.

Seems you got to use good "rubber" old fashion real rubber.

It's them chincy Chinese I tell you

For goodness sakes, dont show this to Jim. He's liable to respond with a thousand exclamation marks and question marks..lol

"To minimize the risk of coring, the following should be considered:

1. Do not use large bore needles, as these may cause excessive damage to the rubber stopper with repeated use. This can be counter-intuitive, but large bore needles are found on syringes with LOWER gauges. Try to use syringes with a HIGHER gauge (between 22 and 27 gauge)."

This really threw me for a loop too! If you look at the start of thread it's dated 26 Jan 2014.

I know, how the fuck did we all miss this?

I have defiantly had small flakes of rubber fall in when using an 18g to draw, shit I had it happen this cycle. It is very possable and does happen.

I will say an 18 gauge needle is not necessary.

In fact repetitive use of a needle that large can cause the vial to "leak".

The latter is particularly truce if positive pressure is used to aid AAS removal or when the vial is inverted.

A 20 or even a 22 gauge works fine IME.

However we ROUTINELY use 20 gauge needles to aspirate local an anesthetics from 50cc multi dose Lidocaine vials and again I've not seen the rubber fracture.

Moreover I believe one should also bear in mind bc many synthetic "rubbers" are lighter than water and oil, they are more apt to FLOAT rather than precipitate.

Consequently if precipitation is occurring with any frequency, the problem is the plug itself rather than the consumers technique.

Finally I've no doubt in some instances although the cause was initially assigned to rubber fracture, the real problem was inadequately filtered gear on behalf of the UGL!

Must've been the timeframe when pep was stealing all the fame and attention selling infectious, bunk trash bogo and MFL was starting up. It had to be something major going on to keep this thread under the radar.

I think that's often referred to as DECEPTION, no? Lol!

Lets don't lose track of the thread now. We were talking about rubber.

!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!

Are you familiar with the difference between "coring" (which I have seen on RARE occasion) and rubber fracturing into these SPECKS, NN, NOT. !!!!!!!!!!!!

Moreover didn't the citation your so fond of clearly state the RUBBER FLOATS!!!!!!!!!!!!

OOPS, LMAO !!!!!!!!!!!!

Face it NN your gear is contaminated bunk with antiquated and poorly constructed stoppers!!!!!!!!!

As I said try bullshitting another forum. !!!!!!!

 

[MANWHORE]

This is preposterous!!

I used a big word.. but I don't think it made sense

 

[Dr JIM]

Nice word but as K emphasized we must stick to rubber or rubbers

I've never used a rubber.

Damn ro. I just said that but deleted it....now you'll get us off on another tangent...

Wait, aren't we still talking about stoppers?

No...now were talking about rubbers

 

[PIZZABOY]

Ribs,Dots,Etc.. but why are they all so short?

 

[Dr JIM]

Now I'm confused (it happens more than I'll ever admit ) are we talking about rubbers that stop or rubber stoppers?

 

[xgunx]

Whats a rubber?

 

[twistulikepretzel]

i dunno i prefer no specks lol it would be like buying condoms with holes in them would you chance that ??? 8- )
