An attached screw cap eliminates lost closures during high-volume processing, while the integrated O-ring delivers a leak-resistant seal for sensitive specimens. Each tube arrives sterile, ready for immediate use without additional preparation.\u003c\/p\u003e\n\u003cp\u003eDesigned to accept a color insert, this microtube supports rapid visual sample sorting across racks and freezer boxes. Laboratories handling large sample sets benefit from clear differentiation that reduces handling errors. The attached cap design keeps the closure tethered, streamlining single-handed operation at the bench.\u003c\/p\u003e\n\u003cp\u003eConstructed from polypropylene (PP), the tube resists chemical attack and tolerates the temperature swings common in cold storage and centrifugation workflows. Sterile packaging supports applications where contamination control matters. Tubes ship 500 per bag, two bags per unit, for predictable inventory planning.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eGlobe Scientific\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e111730\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eMicrotube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity\u003c\/td\u003e\n\u003ctd\u003e2mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCap Style\u003c\/td\u003e\n\u003ctd\u003eAttached Screw Cap for Color Insert\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeal\u003c\/td\u003e\n\u003ctd\u003eO-Ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSterility\u003c\/td\u003e\n\u003ctd\u003eSterile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolypropylene (PP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBag Quantity\u003c\/td\u003e\n\u003ctd\u003e500\/Bag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBags per Unit\u003c\/td\u003e\n\u003ctd\u003e2 Bags\/Unit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUnit of Measure\u003c\/td\u003e\n\u003ctd\u003eCS\/1000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUnit Quantity\u003c\/td\u003e\n\u003ctd\u003e1000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor Insert\u003c\/td\u003e\n\u003ctd\u003eContact for specification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax RCF Rating\u003c\/td\u003e\n\u003ctd\u003eContact for specification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eAvailable Configurations\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003cth\u003eDescription\u003c\/th\u003e\n\u003cth\u003ePack\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e111730\u003c\/td\u003e\n\u003ctd\u003eMicrotube, 2mL, Attached Screw Cap for Color Insert, with O-Ring, Sterile, PP\u003c\/td\u003e\n\u003ctd\u003e500\/Bag, 2 Bags\/Unit (1000\/Case)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLaboratory Applications\u003c\/h2\u003e\n\u003cp\u003eSterile screw cap microtubes serve sample archiving, aliquoting, and long-term storage in molecular biology and clinical labs.
