When laboratories work with Agars and other liquids in Petri dishes, the materials in the dish are often a bit thick and need to be spread down a bit more evenly than one might need for a home science project. This is why we offer labs a wide variety of disposable spreaders.
The spreaders come in a variety of shapes, and they are sterile, packed either individually or in packs of 10-25 spreaders in a peel. The most basic spreader is the T-Spreader:
These T-shaped spreaders are 140mm long with a 34mm crossing bar. They are sold sterile in 10 spreaders in a peel (pack) or individually sterile-wrapped. In either case they are sold as packs of 500 spreaders.
The next shape is the popular L-Shaped Spreader . This shape of spreader allows one to spread the bacteriological material evenly around a petri dish or plate.
The handle on these L-Shaped spreaders is 156mm with a the spreading ‘L’ arm being 38mm long. Like the T-Shaped Spreaders the L-Shape come as a 10 sterile spreaders per peel or individually wrapped sterile spreaders. Again both come in packs of 500 spreaders
The final design of spreader are the triangular spreaders. Which come in two sizes:
Traingular models are bets used when doing Colony Forming Unit counts (CFU Counts) and have grooved handles for easy grip. The triangular spreaders come in two sizes, the smaller unit is 30mm on the spreading side of the triangle, with a handle that is 207mm long. Triangle spreaders are sold as 25 spreaders per peel in packs of 100 spreaders or as 500 individually wrapped sterile spreaders.
The larger size of spreader is 60mm on the spreading end of the spreader with a 235mm handle. They are sold in packs of 100 spreaders with 25 sterile spreaders per peel or as 500 individually wrapped sterile spreaders
