This HBS Test Kit provides the core borosilicate tools used in Opal Professor Laboratory hydrophane testing. Each kit includes a 60mm borosilicate glass Petri dish, two 1ml borosilicate glass pipettes, and a borosilicate glass stirring spoon, giving you the same calibrated setup used in official HBS demonstrations. Designed for accurate immersion testing, absorption observation, and stability documentation, this kit lets you perform real hydrophane behavior analysis at home with the same workflow used in the OPL lab. Ideal for students learning HBS fundamentals, collectors verifying stability before cutting, and sellers who want reliable, repeatable results for provenance and report card preparation.
