The package includes 200 vials, 200 plastic-aluminum flip off caps and 200 rubber stoppers, and the reviewer found the combination of a crimp top and rubber seal delivers a noticeably tight seal that reduces evaporation and preserves volatile samples during storage or analysis.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete pack:\u003c\/strong\u003e Includes 200 x 10ml vials plus 200 plastic-aluminum caps and 200 rubber stoppers so you have matching components for every vial in the box.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecure sealing:\u003c\/strong\u003e The plastic-aluminum flip off cap together with the rubber stopper provides a crimp-style seal that reduces the risk of sample evaporation during storage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBorosilicate glass:\u003c\/strong\u003e Made from thermal-shock resistant borosilicate that tolerates heating and boiling for cleaning without obvious distortion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat bottom design:\u003c\/strong\u003e The flat bottom ensures even heat distribution when heating or storing and improves stability on benchtops and in racks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible form factor:\u003c\/strong\u003e Standard 20mm caps and stoppers fit common autosamplers and lab equipment used for sample handling and SPME workflows.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThese vials suit small labs, research groups, and home formulators who need bulk, consistent sample containers for chemicals, extracts, beauty product samples, or analytical prep.
