In this activity, students engage in a game of beanbag tossbut instead of merely keeping score, they explore statistical concepts such as mean, median, mode, and range. With this in mind, if you are storing your pH probe in tap water or any other solution, then, during storage instead of contaminated KCl flushing out and fresh KCl going in, instead what you'll find is your storage solution (be it tap water or maybe pH4 solution) will be going into your probe instead. This is because some of the gel that inside your pH probe can flush out during use - if this happens in storage however, it means that fresh new KCl solution (from your storage cap of your pH probe) will then replace the solution that has flushed out of the probe. You need to be comfortable and find the proper fit, VWR wants to help find the best pipette for you.
