All Day Vapes Premixed Concentrates

All our premixed concentrates have been formulated to be mixed at 10% for ease of use. This makes it easy for anyone to mix e liquids and have quality juices to vape at lowest cost, with no experience.

If mixed correctly, with high quality PG, VG and nicotine, the resultant juice should be identical to our made to order e-liquids so the reviews in the e-liquids section can be used as a guide for selecting flavours.

To make 100ml of juice you need to mix 10ml premixed concentrate into 90ml base.

Nicotine: In general people talk of say 3mg or 6mg nicotine. What this actually means is 3mg/ml or 6mg/ml nicotine.

Normally you would buy nicotine from vendors at 36mg/ml If you buy 100ml 36mg nicotine the bottle contains 3600mg (100x36) nicotine, usually suspended in PG (Propylene Glycol), though it is possible to find nicotine in VG (Vegetable Glycerin) or a mix of PG and VG.


Say you want to make 100ml juice at 3mg/ml nicotine and a VG/PG ratio of 70/30. You have 36mg/ml nicotine suspended in 100% PG. You also have PG and VG. (DO use BP (British Pharmacopoeia) or USP (United States Pharmacopeia) grade VG and PG).

Premix 10ml (suspended in PG)
Required nicotine level 3mg/ml therefore 100ml juice must contain 300mg nicotine. You need 300/36 ml of your 36mg/ml nicotine. That is 8.33ml nic.
You want 30% PG base. 30% of 100ml is 30ml. The above are all in PG so to find the PG to add the above 2 have to be deducted from the total PG required. 30ml – 8.33ml – 10ml = 11.67ml PG.
70% VG of 100ml = 70ml VG

So to make 100ml 3mg 70/30 juice you need to mix:

10ml concentrate
8.33ml nicotine
11.67ml PG
70ml VG

Quality and Freshness

As part of our commitment to quality we do not buy flavourings from wholesalers that sell various brands in order to reduce shipping costs, because we do not know for how long the products have been standing in their warehouses.

Our flavour concentrates are imported directly from the manufacturers. The shorter supply line helps ensure quality and freshness, even though it may increase costs due to expensive shipping from various manufacturers.
