Science Classroom Supplies

More Information

Classroom lab supplies for middle school, high school, and college science teachers: laboratory chemicals and reagents, borosilicate glassware, plasticware, lab equipment, and scientific demonstration apparatus. The Lab Stockroom stocks the consumables and durable equipment a science department restocks every term, so a teacher can source a full lab from one supplier instead of five.

Every product page lists clear specifications, materials, and use cases, so an educator can confirm a product fits the lesson before ordering. Classroom-durable construction, curriculum-relevant specs, and fast restocking are the standard across the catalog, whether the order is a single replacement beaker or a full back-to-school resupply.

Classroom Lab Supplies by Category

Chemistry teaching supplies include borosilicate glass beakers, Erlenmeyer flasks, graduated cylinders, burettes, and a deep catalog of laboratory chemicals, reagents, acids, bases, and indicator solutions for titration, stoichiometry, and reaction labs. Educational lab equipment covers retort stands, clamps and bossheads, filter paper, test tube racks, lab safety supplies, and the everyday tools a science classroom relies on. Physics and physical science programs use Scientific Demonstration Equipment for mechanics, electricity, magnetism, and optics, alongside spectrum tubes, density sets, and circuit kits. Together these cover the science experiment supplies a STEM and science program needs from middle school through college.

Products in this catalog are aligned to common science curricula, with specifications written so a teacher or department lead can match a product to a standard or lesson. For larger orders, district-wide standardization, or tax-exempt purchasing, our team can prepare a quote and process a purchase order directly.
