5ml UV Glass Jars. Tan or Purple PTFE Lid.
True ultraviolet glass, not painted, with a flush PTFE lid. The standard retail size for up to a gram of concentrate. Choose your lid colour at checkout. Not childproof.
Why violet glass and not amber, green, or clear
Light is what degrades what you are storing. Terpenes oxidise and THC converts to CBN, and the blue and green wavelengths do most of that work. Clear glass stops none of it. Green glass stops some. Amber stops more but still passes visible light.
Violet glass blocks effectively all visible light, roughly 380 to 780 nanometres, while letting UV-A and infrared through. That is the whole reason the glass is this colour, and it is why pharmacies used dark glass long before anyone was storing concentrate in it.
Ours is true ultraviolet glass all the way through, not clear glass with a coloured coating sprayed on the outside. A painted jar scratches, chips, and stops protecting anything. We use these jars ourselves in Humboldt County and they are what local processors here buy.
Bulk rosin jars and wholesale concentrate packaging
This is the standard retail size for solventless extract. It holds up to a gram of rosin, hash rosin, wax, live resin, shatter, badder, sauce, diamonds or dry sift.
Our bulk minimum is 100 jars. Most packaging distributors will not talk to you under 250 to 400, which is why small brands and home pressers end up here.
The reason it matters: high intensity direct light has been measured destroying up to 99 percent of terpenes in 24 hours, and even ordinary LED lighting costs 15 to 20 percent over 90 days. Real ultraviolet glass blocks that light and keeps your terps, colour and potency intact from press day to sale day.
These are built to match the sizing and profile of the premium European jars, so they drop straight into a line already using them, at a fraction of the price.
Whether you need rosin jars in bulk, dab containers wholesale, or airtight glass concentrate containers for dispensary packaging, these ship fast from Humboldt County, California. We use them for our own products and so do local processors.
