Validated compatibility extends beyond Oxford® to several other major pipettor brands: the Socorex Acura® 825\/835 (10 mL), Thermo Fisher Finnpipette® F1 5 mL and 10 mL models, and the VWR® Signature™ large-volume pipettor also accept these tips under standard conditions. As with any multi-brand consumable, a five-tip aspiration validation test is recommended before committing to a large purchase volume, since pipettor shaft tolerances can vary across instrument generations.\u003c\/p\u003e\n\n\u003ch2\u003eChemical Resistance\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eReagent \/ Condition\u003c\/th\u003e\n\u003cth\u003eCompatibility\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAqueous buffers and saline\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDilute acids and bases\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEthanol (\u0026lt;70%)\u003c\/td\u003e\n\u003ctd\u003eGood — short-term contact\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsopropanol (IPA)\u003c\/td\u003e\n\u003ctd\u003eGood — short-term contact\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAcetone \/ chloroform \/ aromatic solvents\u003c\/td\u003e\n\u003ctd\u003eNot recommended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutoclaving\u003c\/td\u003e\n\u003ctd\u003eCompatible (PP is autoclavable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eQuality \u0026amp; Procurement\u003c\/h2\u003e\n\u003cp\u003eMade in USA, these Caplugs® Evergreen Visu-Chek™ tips are precision-molded from virgin polypropylene resin that is BPA-free and phthalate-free, with each lot independently tested and certified RNase-free, DNase-free, and pyrogen-free.
