The RV-Pette PRO 12.5 mL tips use a standard snap-fit piston design compatible with common repeat-volume pipettors that accept this format. Confirm your dispenser's tip range supports a 12.5 mL increment before ordering. What is the difference between SKU 3929 and 3929S? SKU 3929 is the non-sterile version for general dispensing, while 3929S is certified sterile for applications requiring contamination control such as cell culture and PCR setup. Both share identical 12.5 mL polypropylene construction. How are the sterile tips certified? The 3929S tips are supplied certified sterile and individual cases carry lot numbers for documentation. We do not issue specific certificate numbers here; request a lot-specific certificate of analysis through our procurement team. Can these tips be used with organic solvents? Polypropylene handles aqueous buffers, dilute acids and bases, and alcohols well. Limit exposure to acetonitrile, and avoid aromatic and chlorinated solvents, which can degrade the material and affect dispensing accuracy. { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "Are these tips compatible with my repeat-volume pipettor?", "acceptedAnswer": { "@type": "Answer", "text": "The RV-Pette PRO 12.5 mL tips use a standard snap-fit piston design compatible with common repeat-volume pipettors that accept this format.
