Nalgene* Mason Jars

These durable jars have 70 mm necks which tak fixtures or closures with Mason jar threads. Can also be sued with Osterizer and other blenders with Mason jar threads. Like NALGENE bottles, these jars have a neck ring for shrink seal. Also handy for fluid transfer in the lab or field when used with fluid-transfer closure. Refer to that product description for guidelines. Note: Before autoclaving, just set cap or closure on top of the container without engaging the threads.
