PMP (TPX) Beakers with Molded Graduations, 25 mL to 5000 mL
The Globe Scientific PMP (TPX) Beaker delivers near-glass clarity in a shatter-resistant, autoclavable polymethylpentene body, making it suited to reagent preparation, buffer mixing, and routine volumetric estimation at the bench. Molded graduations stay legible after repeated washing and sterilization cycles, supporting general chemistry, sample handling, and media work.

Frequently Asked Questions
Are these PMP beakers autoclavable?
Yes. Polymethylpentene tolerates standard steam autoclaving at 121°C, so beakers can be repeatedly sterilized for reuse, provided they are clean and free of residual solvents.
Why choose PMP (TPX) over polypropylene?
PMP offers glass-like transparency for reading meniscus levels and color changes, while polypropylene is translucent. Both resist many aqueous reagents, but PMP's clarity better suits visual endpoint work.
Do the -1 SKUs ship as single beakers?
Yes. The -1 SKUs are priced and sold as individual beakers, while the base SKUs are case packs. Confirm case quantity by size before ordering large volumes.
Can these beakers be used with organic solvents?
Aqueous buffers, dilute acids, alcohols, and dilute bases are well tolerated. Avoid aromatic and chlorinated solvents, which can swell or degrade PMP. Limit acetonitrile to brief contact.
