CELLTREAT Cell Scrapers are designed for harvesting cells from tissue culture flasks, dishes or bottles. Available in two sizes: 25cm handle with 20mm blade, and new 39cm handle with 30mm blade, for improved access to larger tissue culture vessels. The scraper is available with the blade positioned parallel to the handle (229310 & 229315) for windshield wiper like scraping or perpendicular to the handle (229311 & 229316) for use with a raking motion. Cell scrapers are non-pyrogenic and packaged sterile (gamma irradiated) in individual paper/poly wrappers with 100 pieces per case.
