Machined in pairs, these blocks are precision ground to tolerances thinner than a sheet of paper to give you the flattest and squarest surface for positioning workpieces. Since they are perfectly aligned to one another, they’ll keep your workpieces level and parallel. Also known as 1-2-3 blocks, they're typically used to elevate, support, and align parts for measuring and inspecting. They're made from granite, so they won’t scratch the surface of your workpiece. They also won’t warp when temperatures fluctuate. Unlike metal blocks, these granite blocks are nonmagnetic, so they won’t interfere with sensitive electronic equipment. They come with a certificate of accuracy that's traceable to NIST.

Cleaned and bagged, these well plates won’t contaminate your samples. Each well 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.

Covers—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.
