Beads

Beads are designed to reduce operation times, isolate proteins through affinity binding, and clean equipment. Safer than conducting heat through water, bath beads will not produce dangerous splashes or evaporate which can cause fragile glassware to break. The culturing spheres allow cells to expand and control synthesis. The balls are fabricated in various diameter sizes and materials to meet specific procedure requirements. Requiring less maintenance than alternatives, the beads minimize overall preparation time.
