Gas syringes

Post by RosalieL »

How can you tell if the syringes are too “sticky” for measuring gas? Do you have some that are used for gas only or are your syringes all together? I have found the plastic ones here and I am worried the gas from the experiment won’t have enough pressure to move them. I don’t really have time to try the experiment on all of the syringes. Apparently we also have some glass ones but they haven’t shown up after a quick search. I will have a better look later.

I use the glass ones, clamp a hose on the end so the gas doesn't escape. To get rid of it bubble it out under water.

I did end up finding the glass ones and I showed the teacher and he said “I’m not letting my kids have those!” :cheesy: At least he knows his class!! We ended up using the plastic ones but they weren’t great. I think next year we will do it into a measuring cylinder upside down filled with water. I’m pretty sure that’s what my old school did years ago.
