Frequently Asked Questions What material are these square bottles made from? Bottles are molded from PETG, a clear, impact-resistant plastic, while the screwcap is polypropylene. This pairing suits aqueous media and buffers but is not recommended for aromatic, chlorinated, or strong polar organic solvents. Are these bottles supplied sterile? No. These bottles ship non-sterile. If your protocol requires sterility, validate an appropriate decontamination method that is compatible with PETG, since the resin is sensitive to autoclave temperatures. Why choose a square bottle over a round one? Square bottles pack tightly on shelves, in incubators, and inside cold rooms, reducing wasted space between containers. Their flat sides also resist rolling and present a larger surface for labeling. How are these bottles sold and priced? Each SKU is sold per case, and listed prices reflect the full case as Globe Scientific supplies it. Pack quantity varies by volume, so confirm the case count on the product page before ordering. { "@context": "https://schema.org", "@type": "Product", "name": "Wide-Mouth Square Bottles with Screwcap, PETG — 25 mL to 2000 mL", "brand": {"@type": "Brand", "name": "Globe Scientific"}, "description": "Globe Scientific wide-mouth square PETG bottles with leak-resistant polypropylene screwcap, available in 25 mL to 2000 mL, sold per case.", "offers": { "@type": "AggregateOffer", "priceCurrency": "USD", "lowPrice": "119.61", "highPrice": "335.00", "offerCount": "7", "offers": [ {"@type": "Offer", "sku": "600608", "price": "203.85", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "600609", "price": "254.60", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "600610", "price": "335.00", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "600611", "price": "178.65", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "600612", "price": "119.61", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "600613", "price": "173.80", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "600614", "price": "288.18", "priceCurrency": "USD"} ] } } { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ {"@type": "Question", "name": "What material are these square bottles made from?", "acceptedAnswer": {"@type": "Answer", "text": "Bottles are molded from PETG, a clear, impact-resistant plastic, while the screwcap is polypropylene.
