The vial typically features a heavy-wall construction for added durability and a standard screw thread finish (20-400) designed to accept open-top caps with septa for closed-system reactions or sampling.\u003c\/p\u003e","brand":"Kimble-Chase","offers":[{"title":"Default Title","offer_id":44498101633276,"sku":"2179","price":112.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/kimble-chase-clear-glass-vial-5-ml-tapered-base-12-vials-lab-consumablestubes-vials-and-flasks-kimble-chase-619980.jpg?v=1727045651"},{"product_id":"fisherbrand-centrifuge-tube-1-5-ml-screw-cap-with-o-ring-free-standing-polypropylene","title":"Fisherbrand Centrifuge Tube 1.5  ml Screw Cap with O-Ring 500 Tubes","description":"\u003ch3\u003eFisherbrand 02-681-372 Screw-Cap Microcentrifuge Tube – 1.5 mL, O-Ring, Polypropylene\u003c\/h3\u003e\n\u003cp\u003eThe Fisherbrand 02-681-372 is a premium 1.5 mL microcentrifuge tube designed for applications that require a higher level of security than a standard snap-cap tube can provide.

Manufactured from high-quality Type I borosilicate glass, these vials provide exceptional chemical resistance, ensuring that no ions or impurities leach into the stored solution. The amber coloring naturally filters out damaging ultraviolet (UV) and visible light in the 290 to 500 nm range, making it indispensable for photosensitive proteins, vitamins, and light-degrading reagents. Designed with a standard 20 mm crimp-top neck finish, these vials are intended to be securely closed with aluminum seals and rubber septa, creating a leak-proof, tamper-evident barrier for volatile substances or long-term cryogenic archiving.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eAmber UV Protection:\u003c\/b\u003e The dark amber glass effectively blocks harmful light wavelengths, safeguarding sensitive compounds from photo-degradation without the need for secondary foil wrapping.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eType I Borosilicate Glass:\u003c\/b\u003e Provides a highly inert, non-reactive interior surface that minimizes pH shifts and prevents chemical interactions with aggressive solvents or concentrated acids.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003e20 mm Crimp Top Finish:\u003c\/b\u003e The heavy-duty neck is designed to withstand the downward pressure of mechanical crimping tools, ensuring a tight, uniform seal that prevents evaporation and contamination.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHeavy-Wall Construction:\u003c\/b\u003e Built to endure extreme temperature shifts, making these vials perfectly suited for lyophilization processes, autoclave sterilization, and deep-freeze (-80°C) storage.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e 223695 (DWK Life Sciences \/ Wheaton)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eVolume Capacity:\u003c\/b\u003e 5.0 mL\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaterial:\u003c\/b\u003e Amber Type I Borosilicate Glass\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eDimensions:\u003c\/b\u003e 22 mm OD x 44 mm Height\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eNeck Finish:\u003c\/b\u003e 20 mm Crimp Top\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePackaging:\u003c\/b\u003e Typically sold in bulk shrink-wrapped modules to prevent particulate contamination.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eLyophilization (Freeze-Drying):\u003c\/b\u003e The go-to vessel for producing freeze-dried biologics, allowing for a slotted rubber stopper to vent moisture before being fully seated and crimped under a vacuum.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSample Archiving:\u003c\/b\u003e The crimped aluminum seal guarantees sample integrity, providing clear tamper evidence for banked sera, antibodies, and reference standards.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eLight-Sensitive Reagents:\u003c\/b\u003e Essential for the storage of photo-reactive chromatography standards, vitamins, and specialized pharmaceuticals.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHigh-Throughput Automation:\u003c\/b\u003e The standard 22 x 44 mm footprint ensures compatibility with a wide range of automated liquid handlers, autosamplers, and robotic crimping machines.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\u003cp style=\"margin: 0; font-size: 0.8em;\"\u003e\u003ci\u003eAll product names, logos, and brands are property of their respective owners.\u003c\/i\u003e\u003c\/p\u003e","brand":"WHEATON","offers":[{"title":"Default Title","offer_id":44498242568444,"sku":"4650","price":55.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/wheaton-amber-glass-vial-5-ml-crimp-neck-22-x-44-mm-143-vials-vials-wheaton-166109.jpg?v=1763349805"},{"product_id":"dupont-8-tube-strip-with-orange-tabs","title":"DuPont 8-Tube Strip with Orange Tabs 3360 Tube Strips","description":"\u003ch3\u003eDuPont SP-5100\/OR 8-Tube Strips – Polypropylene, Orange Tabs\u003c\/h3\u003e\n\u003cp\u003eThe DuPont SP-5100\/OR is a premium 8-tube PCR strip designed for high-throughput molecular biology workflows, precise thermal cycling, and advanced diagnostic testing.
