品牌:Axygen/爱思进产品介绍:Axygen® 0.2 mL thin-wall 8 strip PCR tubes, available in an assortment of colors are designed to fit a wide variety of thermal cyclers. Ultra-thin and consistent wall thickness allows precise thermal transfer, even insertion cap ensures a tight fit to prevent evaporation.RNase-/DNase-freeNonpyrogenicNonsterileCaps sold separatelyManufactured with 99.9% pure virgin polypropylene
品牌:Axygen/爱思进关联产品:产品介绍:Axygen® Low Profile 8-Strip PCR tubes are ideal for low sample volume reactions. Using highly polished and precise molds, our tubes ensure precise thermal transfer and a leak-proof seal with a choice of strip caps. The low profile design allows reduced reaction time and evaporation due to less dead air volume. Tubes are available in white and clear with or without caps. Tubes are DNase-/RNase-free and nonpyrogenic.Low profile design results in faster and more efficient PCR reactionsIdeal for 0.1 mL thermal cyclersAvailable in white or clearReal time optimized, clear, PCR 8-Strip caps, domed 8-strip caps and 8-strip frosted flat acapsDNase-/RNase-free and NonpyrogenicRecommended volume range = 5 µL to 125 µL
