Based in Germany since 1985, and with its German engineering, Nautilus Marine Service achieved international reputation by its high quality VITROVEX®deep sea glass housings in different shapes, sizes and pressure ratings up to full ocean depth.

VITROVEX Flotation Spheres

VITROVEX glass flotation spheres are composed of two mated glass hemispheres that are evacuated and locked into position by a sealant and a protective tape. Once the spheres are sealed, the two hemispheres are kept together by the atmospheric pressure on land and the pressure of the water column when deployed.

Nautilus Floatation

Protective shells are available for VITROVEX glass flotation spheres in smooth or ribbed design and bright orange colour. They can be used to assist mounting and retention or just as protection for the sphere. Protective shells are neutrally buoyant and made of polyethylene. In addition to that, VITROVEX flotation spheres can be complemented by a mounting framework with swivelling sphere fixings, specially braided fiber ropes, thimbles and shackles.

Instrument housings

VITROVEX instrument spheres are composed of two mated hemispheres that are evacuated and locked into position by a sealant and a protective tape. Once the spheres are sealed, the two hemispheres are kept together by the atmospheric pressure on land and the pressure of the water column when deployed. Instrument housings usually incorporate a vacuum port to facilitate repeated sealing and unsealing actions. Parting plane sealing faces and ground flats around drill holes are honed to a precise flatness and finish.

Nautilus Instrument Housing

VITROVEX instrument housings can also be designed in a cylindrical form, together with different end cap solutions such as glass, titanium or a combination thereof.

VITROVEX  instrument housings can be made with a variety of high precision drill holes to accommodate connectors, feedthroughs, and a vacuum port for connection to electronics and batteries inside, or releases, sensors or other packages on the outside.

Control of instruments including data up/download may be done through the glass

  • with Hall effect,
  • reed switches,
  • infrared,
  • bluetooth
  • commonly available electrical connectors

Radio and flashing light recovery beacons work effectively housed internally. GPS, ARGOS, or Iridium transceivers as well as VHF radio links penetrate the glass without problem. Status lights and LCD displays are visible before deployment.

High-quality VITROVEX glass can be polished to enhance optical properties for high-resolution digital camera/video applications.
