0.65ml attached cap microtubes for PCR / in-gel digestion, .65mL

0.65 mL Secure Seal Graduated FlatTop Low Binding Microtubes. These tubes are ideal for PCR or protein in solution applications such as in gel digestion. Packaged as 500 tubes per pack. These microtubes are virtually transparent for a better view, and they far exceed the toughness of any other microcentrifuge tube. When the FlatTop cap is closed there will be an audible "snap" that indicates a secure closure has been formed. Made of tough, clear, proprietary formulated siliconized polypropylene, the microtubes are not recommended for autoclaving. They are manufactured for high impact and will withstand over 30,000 x G during centrifugation. Suitable temperature range: -80°C (-112°F) to 121°C (250°F).
