Rubber Stoppers, Size #0, Karter Scientific 216K2 (Pack of 6)

They are made of rubber and fit into my new Corning flask, made in Germany.
If you're ordering lots of different styles of stoppers for your large project, a note for you cork stoppers use a different sizing system than rubber stoppers. The flask on my bench had "7 stopper" printed right on the side and I wasn't able to erase it.

So, that is the size of your RUBBER stopper. Whatever, it fits nicely about 2/3 into the flask's neck. In my case, it will be used to cap bottles of boiled water for a sonoluminescence project. Some stoppers can fit too well, so if the liquid inside cools, it will suck the stopper into the bottle! I think I'll be able to handle these. We were not able to detect any peculiar smell or feel coming from the stoppers. It does have that rubber store smell at first, but it fades quickly. It is common to find a stopper that is greasy, as if the rubber is slipping off and forming a sludge. My experience working on the plasma fuser demo model is with silicone stoppers, but also these seem like nice inert materials.

Yep, good old non-perishables. This is a descriptive stopper. The situation is not dramatic. It just occurred to me that I should have been paid by the word instead of working as a Taking down a stopper is Each of them comes in three packages. I'm Michael from Detroit, I'm interested in science.

A hanger in the back of my wife's car rattled because it was tapping against the frame as the exhaust went through. A hole was drilled through one of these and the hanger was slipped over it. Since it hasn't been necessary for me to listen to her complain about the annoying rattle under the car, I consider it money well spent! Rest of them will go in the bin. I'll use them for something.

The fit perfectly into the one-gallon buckets I need a rubber stopper to replace the metal cap on one that I am using to store acid since the metal cap rusted off. I had been using glass cider/apple juice jugs for years. That purpose is served well by their snug fit.

I used the stopper to close off the bottom of my shower drain so I could disinfect it after a sewer backup, and I used it to close off the bottom opening in my toilet bowl to remove deposits of calcium. As I took the stopper out, I found that it fit well and did not come loose.

This is too short and not accurate in size. There are no standard 2 versions of these. A #12 plug has a top diameter of 5 inches, and a length of about an inch The height of the bottle is too short for much carafes and These containers have a strong chemical scent, quite similar to newly paved asphalt. They should not be used to store food or beverages. A full refund was given for them after they were returned.

Even after all these months - there still were a lot of things in the bag. I may be able to do that in a year and a half The ones I use are still in my home lab (biology hobbyist) and I have not used them all yet.

I've seen the absolute best quality so far. Both the order I made yesterday and the one I received today are the same first quality #3 stoppers I rated 5 Stars on my previous order. Six foil packs of these gums are packaged in a box. The pack is Stoppers made of rubber - The third size is the least dense. Six Karter Scientific batteries (pack of six). In fact, they are not produced by Karter Scientific, but they are marketed under their There is no comparison to these. I've seen the absolute best quality so far. The price for a pack of 6 was $6 a year ago. There is a $14 charge now. The cost per pack of 6 is $9. The fact that these are of the highest quality doesn't hinder my willingness to pay a premium for them. They are the folks at Amazon. This must be the result of reading customer reviews, since they are once again selling these high quality rubber stoppers. I'd like to thank Amazon. Please visit www. com. Is it wood?.

I was looking for something like that. Earlier this year I bought an antique set of salt and pepper shakers with actual cork stoppers, but they were damaged in transit due to dry cork Age had caused it to rot. This stopper replaced the corks I had previously bought and worked splendidly. This is the perfect size, has a good seal, and is When I'm in the mood for salt and pepper, I'm really happy This stopper was used with pepper shrooms so that they could be used. Thanks so much!.
