Unlike glass spreaders, L-shaped spreaders are made of durable polystyrene to be non-breakable and do not pose a safety hazard. L-shaped design for convenient spreading. Just turn the petri dish 360° to provide a smooth and even sample distribution.
L-shaped spreaders provide an economical alternative to bending glass rods or pipets for spreading microbiological samples on agar surfaces and filters in petri dishes. They are supplied sterile -- no need to flame sterilize or autoclave.
