Phenolic Lids are a marvel of modern technology. They have an incredibly high heat tolerance, are chemically inert, and when paired with polycone liners can keep harmful acids, bases, or reactive compounds safe. Phenolic lids are a staple of labs everywhere for their durable, reliable, and safety.
These lids are best suited to our Amber glass boston bottles.
Please ensure that you are matching the correct size cap to your bottle.
