Well Plates
Each well on these plates acts as a mini test tube, allowing you to collect, mix, and store up to 96 individual samples within a single container. Keep track of the location of each of your samples using the labeled grid.
Plates with round wells are better for sample mixing than plates with square wells. Those with U-bottoms facilitate mixing even further. Those with V-bottoms make it easy to retrieve the final drops of a sample, reducing waste.
Add a cover to your plate to protect samples during processing and storage. Covers also make plates stackable. Tight-fitting covers have grooves that protect each well. They prevent evaporation and contamination better than standard covers.
