*Added water to the "dry beads" to see if it makes a difference | |||
**The display says 2C (which it had not before) and the soup is 5C. The water tube in there is still 7C. | |||
**Update, soup at 4c water at 6c | |||
*[[User:Steven J. Koch|Steve Koch]] 00:40, 31 July 2009 (EDT): Awesome study, great work! So it looks like both of them work the same and if we use water, we can get to 5C? Since the fridge is 5C, I think that's sufficient. Thanks for checking this out! We'll have to remember that if we're every being super-delicate and want closer to 0C that we should use ice water...e.g. when resuspending tubulin. | |||

*[[User:Steven J. Koch|Steve Koch]] 00:43, 31 July 2009 (EDT): I didn't follow all of this. But maybe I can help narrow it down a bit. I have always used spring clamps (a triangle-type springy-thing, I believe. They are quite strong and screw into the platform. We shake pretty vigorously, and I can't imagine using anything less sturdy (such as sticky pad). As for versatility--we definitely will want to do different sized flasks, so that will need to be an option. But whether it needs to be "universal," I don't know. Finally, since you've got that temperature probe going, you may as well check out whether the shaker achieves the correct temperature...that would be great! We're mostly likely to use it at 37C, I think. | |||
