BIOAqua Online Refrigerated Auto sampler

The automatic analysis equipments supply information on certain events that happen in the natural environment, providing fundamental information on possible contamination incidents or the quality of bodies of water. Nevertheless, on certain occasions it is necessary to be able to characterise the composition in detail, whether to determine the specific origin of the effluents, or to determine the qualitative composition of the water.

BIOAqua Online Auto Sampler takes samples under optimum conditions for subsequent laboratory analysis. It is an indispensable complement for installations with early warning and continuous analysis units.







BIOAqua Online Auto Sampler – Operation

BIOAqua Online Auto Sampler takes samples at user-definable intervals or at specific times. It is also capable of taking samples responding to alarms from other equipments, probes or remote commands from a control centre.

Before taking each sample, BIOAqua Online Auto Sampler executes an automatic cleaning process of the bottle to fill and the pipes through which the sample will flow to guarantee total renewal. After taking each sample, there is a cycle to empty the pipes to avoid subsequent contamination. The sample is stored in sealable 0.5 l PEHD bottles, which are located in a removable tray. Data relative to the sample can be recorded automatically in a remote control centre.




BIOAqua Online Auto Sampler - System Components

  • Capture system that maintains the sample unchanged, for which there are two options:

    • Peristaltic pump – Takes samples by water suction.
    • Vacuum pump – Takes samples without coming into contact with the pump elements.

  • Cooling system for preserving the samples at 4°C.

  • Data monitoring, acquisition, storage and transmission system.




Unique Characteristics of BIOAqua Online Auto Sampler


  • Recognition of the state of the sample bottles.

  • Automatic emptying system for bottles.

  • Corrosion resistant interior in 316 stainless steel.

  • Sealable bottles.

  • Flexible parameterisation for sampling, volumes, cleaning, etc.

  • Possibility of monitoring using external probes.

  • Sampling triggered by alarms from other units.

  • Self-cleaning system for pipes and capture.

  • Possibility of managing the capture system


Benefits of BIOAqua Online Auto Sampler


  • BIOAqua on line Auto Sampler can work independently at pre programmed schedule to collect and preserve samples for later analysis at the Lab.

  • BIOAqua on line Auto Sampler can work in conjunction with other BIOAqua range of products to collect samples at pre programmed schedule and / or based on certain process conditions.

  • BIOAqua on line Auto Sampler can be operated manually at site to collect samples instantaneously.

  • BIOAqua on line Auto Sampler’s powerful feature allows a company operating multiple sites to collect process and / or effluent samples from a remote location ( Group headquarters or control centre).

  • BIOAqua on line Auto Sampler helps pollution enforcement agencies to collect the samples based on an event at the outlet of a polluting industry, without the plant operators' intervention, from a remote operation centre. The system can preserve the samples with tight integrity; collected samples can then be tested in a laboratory to determine the pollution violation / content.
