These round-bottom tubes are used for the containment, mixing, and heating of aggressive reagents that would otherwise degrade standard glass or plastic labware. The inert nature of the PTFE material ensures minimal sample contamination and prevents the contents from adhering to the vessel walls, facilitating complete sample recovery.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eManufactured from high-quality PTFE for superior resistance to almost all laboratory chemicals and solvents.\u003c\/li\u003e\n\u003cli\u003eFeatures a sturdy round-bottom design with a reinforced lip to assist with secure handling and pouring.\u003c\/li\u003e\n\u003cli\u003eNon-stick surface properties prevent sample carryover and simplify the cleaning process.\u003c\/li\u003e\n\u003cli\u003eMaintains structural integrity across a broad temperature range, suitable for both cryogenic and high-heat applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eHandling of corrosive acids, bases, and organic solvents.\u003c\/li\u003e\n\u003cli\u003eHigh-temperature chemical reactions and sample digestion.\u003c\/li\u003e\n\u003cli\u003eCryogenic storage and processing of sensitive biological or chemical materials.\u003c\/li\u003e\n\u003cli\u003eTrace metal analysis where glass leaching must be avoided.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n\u003cli\u003eFormat: Round bottom with lip\u003c\/li\u003e\n\u003cli\u003eChemical Resistance: Inert to most chemicals and solvents\u003c\/li\u003e\n\u003cli\u003eSurface Property: Non-stick, hydrophobic\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eDisclaimer\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eUsers should ensure that heating is performed evenly and avoid direct contact with concentrated heat sources to prevent deformation.\u003c\/p\u003e","brand":"Fisherbrand","offers":[{"title":"Round-bottom Test Tubes with Lip \/ Plain \/ 145 mm \/ 25 mm \/ PTFE \/ 50 mL \/ Unit \/ New - Unopened (Sealed)","offer_id":54212324655431,"sku":"16265971","price":8.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0802\/7245\/8055\/files\/convert_1c36fecf-bd79-486a-8ee1-0cea9292e167.png?v=1782201569","url":"https:\/\/checkout.wasteless.bio\/en-us\/products\/fisherbrand-ptfe-test-tubes-round-bottom-with-lip-2","provider":"Wasteless Bio","version":"1.0","type":"link"}
