We've been using eScience Labs but their shipping has gone from bad to worse to utterly unacceptable. Our courses operate on 9 week terms and we're on week 4 and 3/4 of the class still doesn't have a kit. The issue is a combination of supply chain issues due to COVID, warehouse management, and corporate policies. I'm considering transitioning to MEL science. There is less flexibility, but I can make it work. Does anyone have first hand experience with MEL chemistry kits? Have you used them for distance laboratory courses?
