How does a Lab Blender Bag work?

1.  The food sample goes into the Grade Blender bag.

2.  A diluent is added.

3.  The bag is then placed in the paddle blending machine.

4.  The machine is then closed and switched on.

5.  This process then blends the contents and diluent into a liquid.

6.  The sample is then pipetted onto a Petri dish using a Grade straw.

7. The sample is incubated and then tested for e.coli, listeria, salmonella

   and other bacteria.
