Disposable plastic spreaders are suitable for bacterial plate spreading experiments and cell culture streaking experiments. 

They are used to evenly spread small volumes (typically 0.2-0.5 mL) of serially diluted bacterial suspensions on pre-poured 

solid culture media by gliding the spreader across the agar surface, resulting in abundant colony formation after incubation.

Polystyrene material.

Individual paper-plastic packaging.

No pyrogens, no endotoxins, no DNA/RNA enzymes, sterilization validity SAL 10-6.
