Unique reservoir features one 100 ml side and one 10 ml side. This “Two-in-One” design is ideal for small volume controls and large volume test reagents. The 100 ml side has a narrow v-shaped channel at the base to maximize reagent use and pour-off spouts at the corners. Stable, 5.75" x 4" wide base prevents spills. Sterilized by gamma irradiation. Ten packs of 10 per case (100). Patent pending.
