How do you extract the VG & PG from the bottles?

Depending on the volume you want to mix can impact what method you use (due to systematic/systemic/random errors). In larger volumes these errors are reduced. In vaping terms an error of 95-105% of the label claim (which is why we can buy a max of 7.2%nic and not 7.5%nic which is the limit before you need a poison licence). The smaller the mix then the bigger chance of not being able to mix the perfect batch

Thanks. I do 50ml and will move to 100ml once i get suitable scales. The ones i posted the link to above look ok??
 
I bought 2 of these sauce bottles from FastTech - SKU 3478402 - one each for PG and VG. This makes adding the diluents to 10ml bottles or jars for weighing very straightforward, no need for syringes or a drawing needle. Am sure you can find similar for cheap on amazon or ebay.

Digital scales are cheap, cheap, cheap! I was a reluctant convert to weighing, I still use syringes from time to time as I can't be arsed finding out the gms per 1ml of every concentrate.
I have a scale accurate to 0.1mg which usefully also weighs up to 2kg. I now have a second scale accurate to 0.01mg but it only weighs up to 200g. Less than £8 each on ebay.
 
Go into any chemist and ask for ORAL syringe, they do them in different sizes , i use the 5 and 10 ml ones.
Now what is great about them is they come with their own little bottle bung that you push the syringe in , turn the bottle upside down and draw the liquid into the syringe , the bung fits lots of different size bottle openings, they cost about £1.00
they are great and no more decanting part filled bottles. They also come in a sealed pack with instructions not that you need them.
Hope this helps.
