Mah fellow Luer Lockers, what is the largest guage you use to withdraw?

[MyB]

Back when I used pond water a 23g would pull air through prior poke sites, so I went to 27g.
With hospira I’ve only had it do it with 18g, so I use 23g and up.

... yeah, i do realize i spelded gauge wrong

[mrjoshua44]

I mainly use either a 25g or 27g.

[BeeKind]

I use a 25g no issues

[vpeps]

I use 25g to deal with moving the liquids around. I have 1.5" needles to be able to reach the bottom of 2ml vials, and 1" for the rest of the cases. 27g is too thin for this, especially at 1.5".

This it the one I use 25G 1.5"

I dont use luer locks for anything anymore. As far as guage 28 for anything oil based and 31 for anything water based.

Have you look into vial adapters?

I've NEVER heard of these! Reposting into category to get more attention.

[MyB]

If you search here for “spike” in posts you’ll find past discussions.
I personally don’t recommend them unless your working in a semi sterile environment.

[pep_researcher]

I have used 23G because what I bought online came with 23G needles included. Have some loose 25G but rarely used them.

[ResearchCat]

@MyB I don’t know much about them but what little I’ve read is bad,

You are correct. They do not stay sterile. If you want to keep the vial adapters on you have to purchase Curio caps by 3m. They are 70% iso alcohol caps that stay on the tip to keep it sterile, but only last 7 days and cannot be reused. I had purchased 100 vial adapters and the Curio caps to use with my Bac water and Luer Lock syringes but after a couple times, I just found it more of a hassle to do that, and switch out caps every 7 days then just using regular syringes. So now I have them sitting here.

If anyone wants my vial adapters and the disinfectant caps for free, I am more than happy to mail them to you if you will use them. Just pay for the shipping.
