I was after some lab bottles for my PG/VG as well as my own liquids when I get around to making some in bulk.
For those in Newcastle I found Australian Scientific. They are based in Kotara just behind Bunnings.
The bottles are made in Germany of borosilicate glass 3.3, autoclavable to 121°C, complete with pouring ring and screw cap made of blue polypropylene to 140 °C. They have sizes from 25mL to 20L.
I paid $9.13 for 100mL bottles and $16.28 for 1L bottles.
You don't need to order them or be a company, you can just go in and buy them over the counter.
They have both amber and clear bottles, although I would guess the amber bottles to be more expensive. It's not an issue for me anyway as I keep all my liquid in a dark cupboard.
I will definitely go back there for more once I hit on a recipe that I like.
I don't work there, just sharing the info
