Empty bottles needed!

OK not quite as silly as it sounds! I have a small source of bulk liquid acids and I need to bottle it for lab use. If anyone in the south east of England has lots of spare bottles with reagent type screw lids there is a possible trade. Most sizes from 250ml to 2500ml winchesters.

Does it all need to be in lab-friendly bottles? If you have more than you can use, why not put it up in beer bottles with crown corks? Then you'll have a premeasured quantity to pour into your screw cap lab bottle when it runs cry.

Oh, and yes- you'll have to keep it out of reach of sports enthusiasts on sunday, and other children. I weep for the man who thinks that "Warning! Contains concentrated nitric acid!" means it's really strong ale.

There is NO way I will put lab chems into food containers unless they are food chems. I am looking for reusable LAB bottles.

Could you not just buy new clean bottles? If you have bulk you could easily earn back the cost of good bottles.

It depends on your acid, but Nalgene PP bottles are cheap (on ebay) and very well made, though I would not put neither concentrated nitric acid nor concentrated hydrochloric acid in them. Else I know that there are some Qorpak bottles sold on ebay all the time ( ), which is of high quality, and those green phenolic caps is lined with teflon.

I have some, used but clean and i'm just west of London.

Most chemical bottles, at least when it comes to glass are just standard soda glass.
Same as what is used in food.

For dry chemicals, stand HDPE and even some PET bottles work just fine.
That is what is standard in the chemical industry.
Also Teflon lined caps are nice but not always needed. Only for the really nasty items should
they be used.

As for labels, one word. Polyester.
Work great, hold up better then most paper labels used. Also fully waterproof.
