Type 1 borosilicate screw-thread vials offer superior heat and chemical resistance. Attached PTFE-lined thermoset caps resist attack from virtually all chemicals.
Sold 144 per case.
Translucent jars include attached white polypropylene unlined screw caps. Excellent chemical resistance and unaffected by temperatures to 257°F (125°C). Autoclavable (disengage threads prior to autoclaving).
Rigid, optically clear jars are great for specimen display, as well as storage. Included are opaque white polypropylene SturdeeSeal® caps, lined with polyethylene foam for a secure seal.
