Review on 📏 125-Foot Parafilm Roll with Width Measurement by Tony Suggs

I have a PhD in biochemistry. I haven't worked in a lab for about five years (I'm in a patent law firm now, so I have a clerical job), but I've developed a few hobbies with chemicals (like patinating metal, etching copper). , etc.). Sometimes I have to do something like saturate the jar's atmosphere with ammonia vapor, and I may even have to let it sit for a few days. Well, I don't want my house to smell like ammonia! I figured, well, I'd use parafilm in the lab to add an extra layer of protection. And then I realized that I could probably find Parafilm on Revain. If you are not used to this product, it is an elastic film that contains no glue. It sticks to itself so there is a paper backing. Simply cut any width of strip (just use regular scissors with parafilm backing attached). It's translucent. It also follows the contours of your container when you stretch it, and once attached it won't peel off glass, metal, plastic or anything else until you want to remove it. (You have to go all the way through the container for the parafilm to come back and touch itself. I hope that makes sense. You can wrap it around a few times for a better/more secure seal.) It lasts a long time even if you don't use it; The same roll used to sit next to my lab bench for years without breaking. It's somewhat heat resistant. I've done several experiments where I heated quartz tubes in an aluminum block to about 260 degrees Celsius with the tops of the tubes open. I put rubber stoppers in the test tubes and wrapped the outsides with parafilm (they weren't the right size to bend the outside of the tube) to seal the gases out of the gas-filled cylinders, which I slipped over the tops of the tubes. There has never been a stench in the laboratory, although I produced all sorts of unpleasant nitrogenous molecules in my experiments. In any case, I would like to say that this product works well even at fairly high temperatures. We would also use it when dissolving urea to make polyacrylamide gels. This takes a long time, so we mixed our reagents in a plastic centrifuge tube, put the cap on, wrapped the cap in parafilm, and then placed it on the dissolution shaker. No leaks! And of course there were dozens of other uses in the lab. I now use it at home to keep the fumes out of my jars and out of my garage (and/or kitchen, as the case may be). In any case, I keep thinking about what I want to use it for at home and my experience so far has taught me that this is a very reliable product. I'm glad I can get it here (and it's the same quality I'm used to).
