5/5

The RSTPK4 Rubber Stoppers, sizes 2 to 8, can be found at the following link There are two items in each assortment As for #5, it is a doosey, with its top and bottom positioned so the bottom is larger than the top, at 27mm and 22mm, respectively. Strange, huh? 5mm, what does that mean? There is one sad sack of stoppers in this sack of stoppers. It is the #6 sack and measures 26mm by I think that #7 is the sweetest one that will probably never get taken advantage of as it measures 29-23 A 37mm lens. I'm so happy! In #8, there are just two holes for 1/4" tubing, and it is just bored at 32 and 40mm like the others. Let me let you guess which stopper was the most abundant out of the 27 that were in the bag. According to the contest rules, the winner will be determined by how many people like this review and dislike it. I have been known to go overboard on my reviews when I start working on them, but the smell of the black rubber was just too overpowering for me when I started this review. In light of the holes and all, I would suggest just plugging them up These stoppers are essential to the nerds who work at the lab. They are, but I would like to know how I am. Stoppers with these qualities are not as good as those made with silicone, but at a lower cost and at a List Price of You can save a total of $11 by paying a total of $20. Since the bags are only 79 cents each) and Prime members receive free shipping, I say it is well worth it It is less common for some to exist It's a $4 savings for you. As listed, they are marked down by $41 (27%) off of their Retail price. You may want to consider it if you are interested in buying one stopper, as I was and was willing to drop the cash on it. It's a sad day for you and me!.

Stoppers made of rubber don't warrant a lot of attention

5/5

Stoppers made of rubber don't warrant a lot of attention. Each of the stopper's holes fits OD 5mm tubing to a T. The rubber is decent quality and keeps the stoppers.

If they're not perfect, what else would you want from them. The set is composed of a few each of each size. These fit easily and seal well into 5mm glass tubing and are convenient for inserting.
