No. These polystyrene tubes ship non-sterile in bulk and are intended for general laboratory use where sterility is not required. What rack and instrument formats fit these tubes? The 13 x 100 mm dimension is a widely adopted standard, fitting most general-purpose racks, vortex adapters, and tube readers designed for 13 mm tubes. Can these tubes be used with organic solvents? Polystyrene resists aqueous buffers and dilute acids and bases well, but it is not recommended for acetonitrile, aromatic, or chlorinated solvents. Use only with compatible reagents. Do the tubes come with caps? No. They are supplied open and bulk-packed at 3000 per case. Compatible 13 mm closures can be ordered separately if needed. { "@context": "https://schema.org", "@type": "Product", "name": "Globe Scientific 13 x 100 mm Test Tubes, 7 mL Polystyrene, Bulk 3000/Case", "brand": { "@type": "Brand", "name": "Globe Scientific" }, "sku": "110415A", "offers": { "@type": "Offer", "priceCurrency": "USD", "price": "258.30", "availability": "https://schema.org/InStock", "seller": { "@type": "Organization", "name": "labsupplies.com" } } } { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "Are these test tubes sterile?", "acceptedAnswer": { "@type": "Answer", "text": "No. These polystyrene tubes ship non-sterile in bulk and are intended for general laboratory use where sterility is not required." } }, { "@type": "Question", "name": "What rack and instrument formats fit these tubes?", "acceptedAnswer": { "@type": "Answer", "text": "The 13 x 100 mm dimension is a widely adopted standard, fitting most general-purpose racks, vortex adapters, and tube readers designed for 13 mm tubes." } }, { "@type": "Question", "name": "Can these tubes be used with organic solvents?", "acceptedAnswer": { "@type": "Answer", "text": "Polystyrene resists aqueous buffers and dilute acids and bases well, but it is not recommended for acetonitrile, aromatic, or chlorinated solvents.
