The connected 8-strip format is the standard configuration for thermocyclers that accept 8-tube strips or 96-well plate blocks, and the thin-wall construction maximizes thermal transfer between the block and sample for fast-PCR protocols and high-ramp-rate instruments. Tubes ship open-top and accept compatible 8-strip flat or domed caps, sold separately.\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\u003e214-3456-080\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFormat\u003c\/td\u003e\n\u003ctd\u003e8-Tube Connected Strip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Volume\u003c\/td\u003e\n\u003ctd\u003e0.2 mL per tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWall Thickness\u003c\/td\u003e\n\u003ctd\u003eThin-Wall\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolypropylene Copolymer (PPC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eNatural\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Closure\u003c\/td\u003e\n\u003ctd\u003eOpen top (compatible 8-strip flat or domed cap, sold separately)\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\u003e125 strips\/Bag (1,000 tubes)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBPA \/ Phthalate \/ Latex\u003c\/td\u003e\n\u003ctd\u003eBPA-Free, Phthalate-Free, Latex-Free\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\u003eStandard PCR and endpoint PCR using thermocyclers configured for 8-tube strips or 96-well plate blocks\u003c\/li\u003e\n\u003cli\u003eReal-time PCR (qPCR) — PPC's superior optical clarity versus homopolymer PP reduces autofluorescence, supporting cleaner fluorescence signal detection\u003c\/li\u003e\n\u003cli\u003eOne-step and two-step RT-PCR protocols requiring consistent thermal uniformity across all 8 tubes\u003c\/li\u003e\n\u003cli\u003eHigh-throughput 8-sample batch screening where the strip format eliminates individual tube handling and ensures repeatable block positioning\u003c\/li\u003e\n\u003cli\u003ePost-PCR gel electrophoresis preparation — 0.2 mL volume is suited for direct gel loading after amplification\u003c\/li\u003e\n\u003cli\u003eShort-term sample storage at 4 °C between PCR steps, capped with compatible 8-strip flat or domed caps\u003c\/li\u003e\n\u003cli\u003e96-well thermocycler workflows using 12 strips × 8 positions to fill the full plate block\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe 214-3456-080 strips are designed for use with PCR thermocyclers that accept the standard 8-tube strip format or 96-well plate blocks from all major thermocycler brands. When using these strips to fill a 96-well block, load 12 strips across 8 positions; any unused wells should be filled with water-loaded strips to maintain thermal uniformity across the block. For qPCR instruments, confirm that your optical module accepts natural (clear) tubes — the PPC material's improved clarity and low autofluorescence make it well suited for fluorescence-based detection through the tube wall. Always verify the strip tube footprint against your specific thermocycler block geometry before transitioning from OEM consumables.\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 \/ PCR master mix\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDilute acids and bases (pH 2–12)\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAlcohols (ethanol, methanol, isopropanol)\u003c\/td\u003e\n\u003ctd\u003eGood — compatible for pre-PCR extraction steps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAcetonitrile (ACN)\u003c\/td\u003e\n\u003ctd\u003eGood — compatible for pre-PCR extraction steps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChlorinated solvents (chloroform, DCM)\u003c\/td\u003e\n\u003ctd\u003eNot recommended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAromatic solvents (toluene, xylene)\u003c\/td\u003e\n\u003ctd\u003eNot recommended\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 PCR tube strips are produced from FDA-compliant, BPA-free, phthalate-free, latex-free PPC resin under ISO 9001 quality management. PPC's copolymer formulation delivers improved optical clarity and cold-temperature flexibility compared to homopolymer polypropylene, making it particularly well suited for fluorescence-based PCR detection and low-temperature sample handling.
