Erlenmeyer flasks with phenolic screw caps are ideal for use as a shaker flask or for mixing, media prep and storage needs. Impact resistant caps are equipped with cemented-in, inert white rubber liners which are resistant to steam sterilization. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance.
