, pencil marks are much cheaper than pen ones because the former can be erased and rewritten to correct mistakes, whereas pens do not allow for this. Number One: Pencils have more benefits than just being easy to erase and use! For instance, they don’t smudge as easily as a pen does if you accidentally push it across your paper while developing- most notably if you are using a pen and pressing down on the paper during development. This will result in an inaccurate slide reading; however, by marking with pencil there is no possibility that this can happen! Number Two: Pens require more maintenance than pencils do. More specifically, pens need ink refills or new cartridges whereas pencils never run out because they are simply made fromTLC plates are a crucial part of the biochemistry lab, and they have many benefits. You will learn about one in particular in this blog post: the ability to use pencil instead of pen to mark your TLC plate. This is advantageous for two reasons. First, it prevents smudging when you press on the paper during development; second, it is less expensive than using pens! In this blog post we’ll explore why marking tlc plates with pencils is such a great idea- check out our top 5 reasons below!
Number One: It prevents smudging. As you develop the TLC plate, it is not uncommon for some of the development to smear onto other parts of your paper- most notably if you are using a pen and pressing down on the paper during development. This will result in an inaccurate slide reading; however, by marking with pencil there is no possibility that this can happen! Number Two: Pens require more maintenance than pencils do. More specifically, pens need ink refills or new cartridges whereas pencils never run out because they are simply made from wood and graphite which last indefinitely (unlike pens). Number Three: Pencil marks are less expensive than pens ones too! While both have their positives and negatives as far as cost goes
