Polypropylene Three-Corner Graduated Beakers, 50–1000 mL, 12/Pack The Globe Scientific Three-Corner Polypropylene Graduated Beaker delivers shatter-resistant performance for routine bench work, reagent preparation, and sample handling. Three pour spouts allow controlled decanting from any orientation, while molded graduations support quick volume estimation during buffer mixing, titration setup, and general liquid transfer.

Bags and cases carry lot numbers that support traceability for CAP-, CLIA-, and ISO 15189-accredited laboratories. Institutional and grant-funded tiered pricing is available on request. Frequently Asked Questions Are these polypropylene beakers autoclavable? Yes. Polypropylene withstands standard steam autoclaving at 121°C, making these beakers suitable for repeated sterilization cycles in routine lab use. How accurate are the molded graduations? The raised molded graduations are intended for approximate volume estimation, not analytical measurement. Use a volumetric flask or calibrated pipette where precise volumes are required. What does the three-corner design provide? Three integrated pour spouts let you decant from multiple positions without rotating the vessel, improving control and reducing spillage during transfer. Which solvents should be avoided? Aromatic and chlorinated solvents are not recommended, as they can swell or degrade polypropylene. Aqueous solutions, dilute acids, and dilute bases are well tolerated. { "@context": "https://schema.org", "@type": "Product", "name": "Three-Corner Polypropylene Graduated Beakers, 50–1000 mL", "brand": {"@type": "Brand", "name": "Globe Scientific"}, "description": "Polypropylene three-corner spout graduated beakers, 50 mL to 1000 mL, autoclavable, 12 per pack.", "offers": { "@type": "AggregateOffer", "priceCurrency": "USD", "lowPrice": "37.20", "highPrice": "239.80", "offerCount": "6", "offers": [ {"@type": "Offer", "sku": "3640", "price": "37.20", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "3641", "price": "56.40", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "3642", "price": "83.20", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "3643", "price": "106.90", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "3644", "price": "155.50", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "3645", "price": "239.80", "priceCurrency": "USD"} ] } } { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ {"@type": "Question", "name": "Are these polypropylene beakers autoclavable?", "acceptedAnswer": {"@type": "Answer", "text": "Yes.
