Use Cell Scraper, Double End for a variety of cell culture applications. Made of high-density polyethylene (HDPE), each cell lifter comes individually wrapped and is sterile, non-pyrogenic, and RNase/DNase-free. The double end design features a flat blade on one end, and either a narrow blade or a narrow J-hook blade on the other. The flat blade makes even contact with growth surfaces and is ideal for harvesting cells in Tissue Culture-Treated Dishes (Catalog #38046) and flat-bottom plates (e.g. 6-well, Catalog #38015/38016). The narrow blade is optimized to fit 96-well plates (e.g. Catalog #38022) and can also be used for resuspending cell pellets in microcentrifuge tubes. The narrow J-hook blade can be used to vertically lift cells from 24-well plates (e.g. Catalog #38017/38021).
