Nalgeneā¢ Polypropylene Floating Microtube Racks
By NalgeThaw, cool and incubate samples at elevated or reduced temperatures. Racks will float with a full load of filled tubes. Tubes are supported below the lip. On benchtop, rack legs prevent bottom of tubes from touching bench surface. Excellent temperature resistance from -70°C to 100°C. Each hole has molded-in letters and numbers for easy sample identification.
NOTE: Polypropylene racks are not autoclavable.
