Test Tube sizes

[craftymel]

What size Test Tubes are you buying?

First there is the diameter: 18mm, 20mm, or 25mm

Then there is the height: 4in, 6in, or 8in

I have not seen the MS tubes in person so I haven't got a clue what to buy. I found an online supplier, but wanted to get some info before I blindly order in bulk (which I have done too often in the past!)

I have seen so many cute templates to hold these but wanted to double check the tube size first!

TIA

I've got a stash of the Martha ones, they're 6.5 inches tall and the diameter is .75 inch, so I guess that would be about 19mm. The top is just a bit flared for the cork, though, so I'm guessing the tube itself would be closer to 18mm.

Where can a person buy these - I would love to get some. I live in Canada but if I can't find them here I will order online. Anyone know????Thanks

I found them here

and I think they are priced pretty well. I don't know about the shipping to Canada.

I just wanted to make sure of the popular size before I ordered.

Jen, Thanks!!! I think I may order the 20mm x 6in size.

I found the Martha Stewart ones at emmaspaperie.com $7.99 for 8 of them . It is a kit. I already got a shipment notice and I placed the order yesterday! I love all the very cool things she has in her store.
