PYREX 50mL Screw Cap Culture Tubes with Phenolic C
Corning These 50mL PYREX® culture tubes are supplied with deep-form 18-415 GPI threaded phenolic caps to facilitate handling and sealing after autoclaving. Caps are fabricated from a special formula resistant to the effects of temperature and steam in autoclaving and are provided with a glued-in, white rubber liner. The white enamel marking spot gives an excellent surface for pencil notations. Pencil marks are easily erased. For replacement phenolic caps, see No. 9999. - COG
