"➡️ TIP: I use the below method to draw up the thicker oils that don't drop easily out of the bottle on their own, and also to drain the last drops out of bottles that are nearly empty, but have that last bit of oil that gets trapped inside. I do this by first inserting the pipette in as far as it will go, then carefully tipping the bottle upside down, I then draw the oil into the pipette and tip the bottle to the side as I remove the pipette."

"Perfect for what I needed."

"Standard small pipettes, work well for essential oils, and the tip is small enough that I don't have to remove the orifice reducer on the bottle unless I want to."

"Not extremely accurate for precise measurements, but I use these to administer chemicals and medicine in my 2.5 gallon aquarium."

"These are great for mixing essential oils and liquids that need to be transferred to other containers."

"Purchased these for painting with watercolor."

"It was my mistake not realizing the size before and cost more than the item was worth to return."

"These will work perfectly for transferring essential oils from bottle to bottle when making blends."

"Dropped a popsicle stick and some agar into each one, sterilized, and transferred a variety of oyster and reishi cultures into them for long term storage."

"The flat bottom allow them to be free standing, which is helpful for them to be free standing."

"For example, one of my feather boards came with a miter and a t-slot hardware and I put whichever I'm not using into a tube and cut a round hole for it to fit in on my rack."

"They do leak sometimes."

"I have been using these for over 2 years to store harvested yeast cultures for home brewing beer."

"I found that the cost was exorbitant for a few tubes that would probably break, wouldn't hold large volumes of beads, and generally had poor reviews. There is a place to write in information (I imagine to record whatever is sampled within) that I will be writing the price of the beads on so I can keep track of the cost that went into the pieces I make.I imagine that if I wanted to, I could find a way to remove the measurements on the other side of the tube that I have no use for (they are in ml which really means nothing to me since I'm not working with liquids), but for now they don't bother me."

"Only complaint is that you need to make sure to get cap on perfectly level before tightening or it will leak."

"These Karter Sci tubes leak from the caps with minimal, by-hand mixing in the tubes."
