200ul & 400ul Tubes

These tubes are precision-molded of virgin, medical-grade polyethylene, and are excellent for storage of biological samples. The polyethylene is soft enough to be cut easily for removal of a pellet from the bottom of the tube. The dimensions of the 200 ul tube allow a pipet tip to reach the bottom of the tube for optimum sample recovery. Both tubes can be frozen to below -70°C.

The 200 ul and 400 ul tubes are available in two styles: capless or with attached, snug-fitting caps. They are also available colorless or in six noncytotoxic, nonmetallic colors. For your convenience, tubes can be ordered in bags of assorted colors (900/bag, 150 of each color).
