Arbor Scientific

I use them constantly in my classroom! Perfect for group work and presentations.

I received excellent customer service today at arbor thanks again

One of lights didn’t work but was replaced by customer service. Kids enjoyed using, was a bit hard to see white light and colors mixing. Used for refraction labs.

Good product, fast service.

Sales team was great, technical support didn't seem to undertsand that iron in the clamp jaws was a show-stopper. We even tried using thick-walled plastic pipe between the clamp and the clear plastic tube, to no avail.
