These test tubes have good chemical stability, light weight, durability and robustness. They can meet basic experimental needs and are suitable for storing items that need to be kept dry or some liquids, and are widely used in a variety of applications. Tips: No more than 1\/2 of the capacity of the test tube when used to contain the solution and no more than 1\/3 of the tube when heated. The outside of the test tube should be wiped dry before heating, and should be clamped by test tube clamp when heating. When heating liquid, the mouth of the tube should not be pointed at people, and the test tube should be tilted to 45 degrees from the desktop, while constantly oscillating, and the upper end of the flame should not exceed the surface of the liquid in the tube. When heating solids, the mouth of the tube is slightly tilted downward.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ Package: 50 pack 16ml transparent glass test tubes with cork stoppers\u003c\/li\u003e\n\u003cli\u003e✅ Size: 20mm(O.D) x 100mm(Height)\u003c\/li\u003e\n\u003cli\u003e✅ Feature: Each set of tubes is equipped with brushes for cleaning\u003c\/li\u003e\n\u003cli\u003e✅ Material: The glass test tubes are made of high-quality 3.3 borosilicate glass and can be heated and reused\u003c\/li\u003e\n\u003cli\u003e✅ Widely Used: These test tubes are perfect for small storage needs, using these clear tubes to carry candy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eShipping \u0026amp; Guarantees\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ FREE standard shipping within the United States (3–6 business days)\u003c\/li\u003e\n\u003cli\u003e✅ 100% money-back guarantee for lost or damaged items\u003c\/li\u003e\n\u003cli\u003e✅ Secure checkout with encrypted payment processing\u003c\/li\u003e\n\u003cli\u003e✅ Shipping via UPS, FedEx, and USPS\u003c\/li\u003e\n\u003cli\u003e✅ Ships to lower 48 states only (no PO Boxes \/ APO \/ FPO)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReturns\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ 30-day hassle-free returns\u003c\/li\u003e\n\u003cli\u003e✅ Items must be unused and in original packaging\u003c\/li\u003e\n\u003cli\u003e✅ Full refund if item is not delivered\u003c\/li\u003e\n\u003cli\u003e✅ Guaranteed delivery within 6–7 business days\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePayment Methods\u003c\/h3\u003e\n\u003cp\u003e✅ Credit Cards, PayPal, Shop Pay, Apple Pay, Google Pay, Amazon Pay, Meta Pay\u003c\/p\u003e\n\u003ch3\u003eCustomer Support\u003c\/h3\u003e\n\u003cp style=\"text-align:left;\"\u003e✅ Questions?
