The BD Falcon 50 ml Polypropylene Conical Tube with Flip-Top Cap is the newest addition to the BD Falcon tube family. It is suited for any research applications requiring one-handed operations to open and close the cap. It also allows researchers to avoid having to remove the cap and either hold it, or place it on a surface away from the tube, before dispensing the contents of the pipette. This design saves time and effort in applications requiring multiple aliquoting, storage, and pouring from the same tube, while maintaining the same superior quality and performance of our standard screw-cap closure. Key applications are e.g. cell pelleting and washing, gradients, sample and buffer storage, DNA/RNA/plasma preps, serial dilutions, sterile tissue collection, immunofluorescent assays, and storage of chemicals
