{"title":"Test Tubes \u0026 Centrifuge Tubes","description":"\u003cp\u003eSupport organized educational experiments with the Test Tubes \u0026amp; Centrifuge Tubes collection at Stemora. This collection includes practical containers for classroom science activities, homeschool lessons, STEM demonstrations, sample organization, and supervised student projects. Browse plastic and glass test tubes, graduated tubes, screw-cap tubes, snap-cap containers, and assorted tube sets in a variety of sizes and packaging quantities.\u003cbr\u003e\u003cbr\u003eProducts can differ in capacity, tube diameter, material, closure type, graduation markings, color, bottom shape, and included accessories. Some tubes are designed for simple mixing or observation, while others are useful for organizing small, nonhazardous educational samples. The presence of the term “centrifuge tube” describes a common product style and does not necessarily mean that every item is suitable for high-speed centrifugation.\u003cbr\u003e\u003cbr\u003eBefore ordering, check the dimensions, material compatibility, temperature limits, leak-resistance claims, and manufacturer instructions. Do not expose tubes to heat, pressure, freezing, chemicals, or mechanical equipment unless the product is specifically rated for that use. Glass tubes can break, and small caps may present a choking hazard, so adult or instructor supervision is recommended.\u003cbr\u003e\u003cbr\u003eStemora offers these products for educational activities and general sample organization. Unless expressly stated in the individual listing, tubes are not sterile and are not intended for clinical collection, medical testing, medication storage, food preparation, microbiological cultures, or human and animal biological materials. Do not place tubes in laboratory centrifuges without confirming their rated speed, rotor compatibility, balance requirements, and intended application.\u003c\/p\u003e","products":[],"url":"https:\/\/stemora.us\/collections\/test-tubes-centrifuge-tubes.oembed","provider":"Stemora","version":"1.0","type":"link"}
