{"title":"Test Tube Racks","description":"\u003cp\u003eKeep tubes upright, separated, and easier to identify with the Test Tube Racks collection at Stemora. Suitable for science classrooms, homeschool experiments, STEM demonstrations, and educational workstations, these racks provide practical support for organizing test tubes, sample tubes, vials, and other compatible containers during approved learning activities.\u003cbr\u003e\u003cbr\u003eAvailable products may include plastic racks, wooden holders, folding designs, stackable racks, detachable models, and multi-level organizers. Racks differ in hole diameter, slot count, spacing, overall dimensions, material, assembly method, and supported tube shape. A rack designed for standard test tubes may not securely hold microtubes, centrifuge-style tubes, culture tubes, or wide sample containers. Compare the product measurements with the outside diameter and base shape of your tubes before ordering.\u003cbr\u003e\u003cbr\u003ePlace racks on a stable, level surface and distribute loaded tubes evenly. Adult or instructor supervision is recommended when racks hold glassware, liquids, staining materials, or small capped containers. A rack supports organization but does not make a tube spillproof or prevent glass from breaking. Inspect products for cracks, loose joints, warping, or unstable feet before each activity.\u003cbr\u003e\u003cbr\u003eStemora’s test tube racks are intended for educational organization and supervised demonstrations. Unless specifically stated in the individual listing, they are not autoclavable, freezer-safe, chemically resistant, flame-resistant, or certified for professional laboratory procedures. Do not use them for clinical specimens, microbiological cultures, hazardous chemicals, medical testing, or other regulated materials requiring validated containment and handling systems.\u003c\/p\u003e","products":[],"url":"https:\/\/stemora.us\/collections\/test-tube-racks.oembed","provider":"Stemora","version":"1.0","type":"link"}
