ABSTRACT:
A cell scraper includes a grip, an elongate arm and a scraper blade. The cell scraper includes a substrate molded from a substantially rigid plastic. The substrate includes a blade support remote from the grip. The cell scraper also includes a resilient material over-molded onto the substrate. The resilient material may be molded onto the grip to facilitate gripping. Additionally, the resilient material is molded around the blade support to define a flexible blade for efficiently scraping cells from a tissue culture vessel.
