Electron Microscopy Sciences Freezer Box, Polycarbonate, For 25 (5x5) 5 mL Tubes

Electron Microscopy Sciences Our new 5 mL five-o screw cap tubes are made of maximim clarity, low-binding virgin polypropylene and are certified rnase and dnase free. They are sized to be compatible with all benchmark (usa) and standard german-designed equipment, including centrifuges, dry bath block heaters, tube racks and thermal shakers/vortexers. Screw cap tubes are supplied with 20 mm OD caps that seal smoothly and completely with a single 360 degree turn. Useful from -86 deg c to 100 deg c, they are a valuable resource for boiling and sample preservation at very low temperatures. The foam racks are similar to the packaging normally associated with 15 mL tubes (upright woth caps attached), but require about 60 percent less storage space. Feature dual graduations at every 0.2 mL and 0.5 ml. - EMS
