Low profile tubes feature precision molded thin walls that provide maximum heat transfer and a shorter length that reduces unnecessary headspace. Normal working capacity of each tube is 100ul and a total capacity of 200ul. Tube strips are free from DNase, RNase, DNA, endotoxins and PCR inhibitors. Tubes available in clear for maximum sample visibility. Caps have an optically clear flat surface.
