These formalin filled specimen containers are designed to provide reliable leak resistance and secure, air tight sealing for the fixation and transport of tissue specimens in histology and pathology laboratories. Each container is prefilled halfway with 10% neutral buffered formalin (NBF), ensuring consistent fixation while reducing handling steps and exposure risk. Manufactured from translucent polypropylene (PP), the containers allow clear visibility of contents and are paired with durable polyethylene (PE) caps that create a dependable, tight seal. Select s feature a positive lock closure with audible confirmation to indicate the container is fully secured for safe transport. For efficient storage and distribution, containers are packaged in inner packs of 24 units, with four inner packs per case, providing a total of 96 containers per case.
