Molded from polypropylene in a natural (clear) color, each tip features Visu-Chek™ graduation markings that let technicians confirm aspirated volume at a glance through the transparent tip body — eliminating the need to verify the pipettor display for routine volume checks. Outer longitudinal ribs add rigidity and ergonomic grip, promoting a secure, leak-free seal during both tip attachment and ejection in high-frequency pipetting workflows.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd\u003e230-1484-03K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolume Range\u003c\/td\u003e\n\u003ctd\u003e1–200 µL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTip Design\u003c\/td\u003e\n\u003ctd\u003eGraduated, Outer Ribs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolypropylene (PP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eNatural (Clear)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSterility\u003c\/td\u003e\n\u003ctd\u003eNon-Sterile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack Size\u003c\/td\u003e\n\u003ctd\u003e1000\/Bag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBPA \/ Phthalate-Free\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Instruments\u003c\/td\u003e\n\u003ctd\u003eOxford® Pipettors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRoutine pipetting and reagent dispensing across the 1–200 µL range with in-line volume confirmation via graduation markings\u003c\/li\u003e\n\u003cli\u003eMolecular biology workflows including PCR setup, gel loading, and nucleic acid dilutions\u003c\/li\u003e\n\u003cli\u003eELISA sample and reagent addition requiring precise low-volume transfers\u003c\/li\u003e\n\u003cli\u003eClinical chemistry and serum\/plasma handling where rapid visual volume verification supports throughput\u003c\/li\u003e\n\u003cli\u003eHigh-frequency pipetting environments where the outer-rib grip reduces attachment force and operator fatigue\u003c\/li\u003e\n\u003cli\u003eCAP\/CLIA and ISO 15189 accredited laboratories requiring lot-traceable consumables\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003ePart number 230-1484-03K is engineered as a drop-in replacement tip for Oxford® pipettors in the 1–200 µL volume class.
