Since the early 1990s Nautilus Marine Service has been successfully producing VITROVEX^®  flotation and instrument housings for deep ocean research in different shapes, sizes and pressure ratings up to full ocean depth. VITROVEX^® glass products are complemented by a comprehensive range of accessories, including vacuum ports, feedthroughs and mounting framework with swiveling sphere fixings, specially braided fiber ropes, thimbles and shackles. 

VITROVEX^® spheres show very little deviation in shape even under high pressure. In addition to precision moulding of the highest quality glass, skilled craftsmanship ensures that each hemisphere is pressed to exactly the same dimensions.
