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 certified DNase-/RNase-free and nonpyrogenic.
