Nautilus Marine Service

All stationary and autonomous instrumentation for observational activities in ocean research have two significant things in common. Firstly they require pressure-resistant housings and secondly they need buoyancy to bring instruments safely back to the surface. The use of glass housings is naturally attractive for meeting both these requirements.

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. As a result VITROVEX® hemispheres of the same outside diameter and wall thickness are

  • completely interchangeable,
  • individually replaceable
  • and require no special alignment during assembly to complete spheres.

More distinguishing features of VITROVEX® glass housings are

  • Immense strength-to-weight ratio
  • Highly resistant to breaking (low thermal expansion coefficient)
  • Inherently inexpensive
  • Corrosion resistant, Non-polluting and ecologically acceptable
  • Remarkable transparency and clarity with smooth, pore-free surface
  • Parting plane sealing faces are honed to a precise flatness and finish
  • Non-magnetic and electrically non-conductive
  • For protection, storage, and ease of handling LDPE (low-density polyethylene) protective shells are available as well as mounting framework with swivelling sphere fixings, rope, thimbles and shackles (EDDYGRIP system)
  • Serial number and a production period are indicated on each hemisphere
