McLane Glass flotation, depth-rated to 6,000m, is ideal for moorings and custom instrument design such as ocean-bottom seismology instruments. Flotation modules with 12” borosilicate glass spheres have 10 to 40kg of buoyancy and are protected by polyethylene, high visibility hardhats. Multiple spheres in a modular configuration have a through-center connecting rod to reduce mooring drag. This design eliminates cable twist for more reliable mooring performance.
We offer three glass flotation models: G2200 single sphere model (10kg of buoyancy), G6600 triple sphere model (30kg of buoyancy), and G8800 quad sphere model (40kg of buoyancy).
