What is the width at the center? I need to know if I can insert them into test tubes with enough room to grab specimens at the bottom.

With tweezers open as in the photo, mine are 3/4 of an inch as the widest point, near center. You could close them a bit to maybe 1/2 an inch, and still be able to close them more to pick up something. Hope this helps.

I threw mine away, but you can figure the width of two spice jars plus add 1/2 to 1 inch for the center. I honestly can't recommend this, though. It started falling apart shortly after I set it up.

They are full sized if you've ever taken a science lab. If not slightly smaller than if you make a circle with your thumbs and pointer fingers. Sorry but I no longer have them and can't measure them.

I use a 26 x 1.95 to 2.25 generic tubes with no issue. Larger tubes are not nessasary and heavier.

It did not come with sample tubes. . You can use regular 1.5ml and 2.0ml microcentrifuge tubes

Never needed to measure them, just used them to display cultural artistry. I would think multiplying the dimension of one by two would get you a size since these are very thin...like rubber coated wire....will not hold heavy items in top cubes.

Greetings. The inside measurement is approximately 1 1/4 inches at the widest point. They can be pinched around a little, so you could customize a bit. Hope this was helpful.

Jill - I bought and used all of the ones I ordered, thus I don't have any at hand to measure. They are small - like a shot glass. I think the LED tealights I have seen would not fit into the bottom. Geo

This isn't scientific (I don't have a ruler handy)... but the AAs stick out about a pinkie's width, and the Ds stick out about a thumb's width. If you have a Duracell D cell, it will slide in until the coppertop portion almost is in line with the tray.

Hello, The tray would fit good. The mold should show where the space is located and the lab tech will be able to work around that for you. If you would like to contact us direct for more info, please feel free to do so. :-) Whiter Smile Labs

I no longer have these tubes. But if you go to any pet shop that uses air tubing attached to individual filters in an aquarium (including under-gravel filters) you will find these tubes and can measure their inside diameter.

The end is aout 1/2", but is flexible, so would fit into a slightly smaller bottle opening. I found the other end to be better at scraping out leftover product.

I can't tell you. I bought these, hot glued them into a stack and then cut them in cubes to use them for something. So I don't have them or I'd measure them for you. Sorry!

You need to measure the inside diameter of the threads in the bottom of the microscope. The supplied adaptor is 48mm and several others are available on the AmScope website. The 48mm thread will measure about 47mm inside.

The ones I got measure a hair over 13/16 inch for the width of the entire bifurcated channel. Other responders have indicated 7/8 or 1 inch, but that would be way loose if, like me, you are cutting a dado slot to drop these into. I can photo the ones I have next to a ruler/scale if you would like and send to you, if you let me know. good luck

To be honest I'm not entirely sure. I'd imagine that any typical size tips would fit they are held in by a screw. I would get the deminsions but I don't have the station handy or a pair of calipers to find out
