cytosub flow cytometer

cytosub module 'shallow'

Pressure housing for outdoor use and submerged use of CytoSense in shallow waters (maximum water depth 20 meter). It should be ordered together with a CytoSense instrument or as an upgrade for an existing CytoSense instrument. Including cylinder, top and bottom cap and O-rings, and bulkhead connectors for cables and fluids, safety moisture sensor. Stainless steel or light weight aluminum versions available.

cytosub module 'deep'

This package transforms a CytoSense bench top flow cytometer into a 'CytoSub' instrument for submerged operation down to 200 meter. It should be ordered together with a CytoSense instrument or as an upgrade for an existing CytoSense instrument. Includes a 200 meter rated pressure housing 320x500 mm (light weight aluminum or stainless steel), a peek sample loop section with a circulation pump and a motorized fluid switch valve to separate the low pressure cytometer from the high pressure sea side, electronic control and adapted software for operation and sampling scheduling, an pressure sensor for depth controlled sampling, high pressure underwater connectors for electricity and sample inlet and outlet lines, a safety moisture sensor. Integration: the CytoSense is directly attached to the top cover of the pressure housing. The sample loop, valve, pump etc. are located on a single mounting plate (viz. photo), forming the left side of the instrument.

mounting rack 'wet'

A light weight, submersible, stainless steel frame for hoisting, protection and general transportation of a CytoSub or a 'Battery pack'. Includes heavy stainless steel wire rope shock and vibration isolators.

data transfer and powering solutions for cytosub

Cable solution
The data and power transport between the submersed instrument and the computer on the ship runs through a high quality submersible cable. Depending on the required length the data transfer can be realized by 'extreme USB', 'extended ethernet' or fibre optic technology. A cable has the advantage of continuous control over / and data acquisition from the submersed instrument. In the case of 'extended ethernet' an embedded computer is used inside the CytoSub.

Autonomous solution
If a long (extra) cable for connecting the ship based computer with the CytoSub is not desired, a solution is offered basing on an emedded computer for control and data storage and a battery pack for powering. The battery pack needs to be lowered together with the CytoSub. The CytoSub runs on fully preprogrammed operation with samplings at preset times or depths (using the pressure sensor). Samplings can also be initiated by an external trigger from another device or from an existing cable. After surfacing again, the measured data files can be conveniently transferred to the shipboard computer through a WIFI link (using a high pressure antenna housing on top of the CytoSub).

Mixed solutions
Combinations of data transfer through a cable and 'close-in' power supply by a batery pack are possible, as well as the other way around: data storage and control using an embedded computer and powering over a cable.

battery pack for cytosub powering

The battery pack consists of a 200 meter rated pressure housing of 250x500 mm (light weight aluminum or stainless steel), filled with leakage-free lead-acid batteries for powering of a CytoSub. Including a 4 m under water cable with mating plugs, and a recharge device and connector.
