StonyLab Capillary Tubes, 100mm Micro Glass Transfer Pipettes, 0.3mm ID x 0.5mm OD, Pack of 1000

Great item and well worth the purchase

Good product for my lab. I like it very much

These are very fine glass tubes that rely mainly on capillary action to draw tiny amounts of liquid for transfer to another surface, for example, transferring a tiny amount of blood to a microscope slide.I mainly use them in model and prop building to transfer a tiny amount of solvent to attach small parts in hard to reach places. I last purchased a box of 1000 about 15 years ago and recently ran out, so these should last for quite a while.They are made of glass, so they are a little fragile, but in most laboratory situations, they're considered disposable.Overall excellent quality!

The media could not be loaded. I was surprised by how thin these were. For reference in thickness I share the typical capillary tubes we use in our chemistry class so I do not feel I will be able to use these with my students who would likely break them each time they used them. I however may be able to get some nice use out of them for smaller chromatography set ups and demonstrations.Each one is super thin and I believe each one I tested with I broke in multiple places by applying a little pressure onto them so you must be extremely delicate with these should you order this size.

Works like a charm. Great value, looks nice, and performs well. Very satisfied and will probably order another one soon.

I don't have a lab...but I do have an art studio and I make miniature things. You know, like 1/2" sofas and things like that. These work as great pipettes for tiny bits of glue.Yes, they break, and the listing SAYS that they do, so please don't knock the manufacturer for that. Treat them with care and respect, take your time, and they will do exactly what they were created to do.I recommend this item.

The capillary tubes I received are what I expected. They function like any standard capillary tubes and are of average quality. However, they are priced a bit higher than similar quality options. Capillary tubes can be even cheaper for those buying in bulk, but for someone with a home laboratory like mine or a homeschooling family, these would be perfectly adequate. They would also be suitable for a small doctor's office. The product description and photos accurately represent the items. They arrived in two days without any issues. I would get these again.

These break very easily and almost unusable.
