If your laboratory, research center or chemical processing plant uses test tubes, chances are high that you will also need laboratory clamps to position, hold and store them. Choices range from ring stand clamps to stand clamp holders to volumetric, multi and platform clamps. You can find laboratory clamps constructed from aluminum, nickel plate, fiberglass and more. In addition to test tubes, laboratory clamps can also be used to hold flasks and beakers. Laboratory supplies and microbiology supplies are available as well.
