If purchasing the ready to go sets, how long can these be kept? Refrigerate until used?

Our Algae Beads should be kept in the light (not direct sunlight!!!) and also not in the refrigerator. Desktop / benchtop is great. You should see color change in the day, and overnight return to yellow. That way you are on-scale when you want to run experiments with your students. We have found them to be active for over 4-months in our labs, so I would safely say 30-days for typical classroom activities. Call us for questions or bulk pricing 760-483-3626

what is the name of the indicator solution that is used/added?

It is a “carbonate ph indicator”.

Does each snap-vial (with beads and indicator) come with a pH indicator strip?

Hi! Each one comes with a pH indicator card. The indicator changes color with the pH.

Can I freeze algae beads for future use (next school year)?

Freezing algae beads: Probably will not live. When you freeze cells ice crystals form. Those crystals grow and cut through the cell membranes rupturing the integrity if the cell. Thus when the cells are thawed the cellular material spills from the cell... and they are dead. There are some procedures to store cells in liquid nitrogen. However there is always a percent of the cells that does not live through the process.

Calling all science teachers!

Used these for photosynthesis and cell respiration basic lab. I used co2 indicator and small cuvettes and a few beads. Had students explore various variables and their effects on carbon dioxide production. Easy visual!!
