Q:

We need to heat up some nutrient agar for a science fair experiment in a microwave. I believe its algae based. Are there any kashrus concerns?

A:


To answer your question, we would have to know more details about exactly which product you were planning on heating up, as some of them can contain non-kosher ingredients such as blood (with innocent-sounding names like “chocolate agar”). However, it may be easiest to avoid the issue by covering the agar (on top and on bottom) when you put it into the microwave, as this will prevent any potential transfer of ta’am/flavor from the agar to the microwave.
