Catalog Number:

Water Bath: Model 283, 13491-032 (VWR), Lab Armor Beads: 42370-002 (MidSci)

Using cell culture, our lab assesses the viability of mouse cortical cells through several assays, including radioactive uptake. Since our culture plates will be out of the incubator for at least 30 minutes, depending on the experiment, we needed an efficient system to maintain temperature. We had used older water baths before, and the “just fill it with a little water" approach. While this worked, it was inefficient. First, they were down in the bottom of the water bath, making it difficult to see, and to work with. Second, the water level had to be just right. Too much water, and the plates would be floating. We searched for a better setup. Our search found the Thermo Scientific Precision Digital Water Bath, along with the Lab Armor Beads.

Experimental Design and Results Summary

Tips

We experimented with the depth of the beads in the reservoir, until we confirmed that our plates, resting on the surface, were actually at 37°C. We used approximately 3L of beads.

Summary

The Good

Reliable water bath, easy to read/use, and is low maintenance.

The Bad

Cost. Currently, $1,300 for the water bath at VWR, and $195 for 2L of beads at MidSci.

The Bottom Line

This water bath/bead combination is perfect for incubation of culture plates. Cells stay warm, as well as the media, and culture plates are stable during experiments.
