Once the location and designation of the sample is determined, it can be done the preparation beforehand infrastructure to facilitate sampling. facilities and infrastructure that need to be prepared include:
Water sampling equipment must meet the following requirements:
- Made of materials that do not affect the properties of the water sample (eg metals for inspection, sampling tool is not made of metal),
- Easily washed from the former previous sample,
- The sample is transferred to the bottle container without residual materials suspended in it,
- Capacity of the tools tailored to the needs and depending on the purpose of examination,
- Easily and safely carried
The sampling equipment consists of several types, its use must be adapted to
- Tool simple samplers (plastic bucket, bottle).
- Regular bottle given ballast that can be used at certain depths.
- Tool horizontally local samplers are used for sampling in rivers or running water at certain depths.
- Sampling tool in an upright, to take samples at locations where the water is calm or flow is very slow at certain depths, such as in lakes, reservoirs and estuaries.
- Tools samplers at a depth that is integrated, to obtain samples representing all water layers.
- Automatic sampling tool, used for a combined sample of wastewater or polluted river water, in order to obtain water quality on average over a given period.
- Making tool for the examination of samples of dissolved gas that comes close so that the tool can be closed immediately after fully charged.
- Making tool for the examination of samples of bacteria, namely cotton closed glass bottle or aluminum foil, heat-resistant and pressure during the sterilization process.
- Tools plankton samples for examination in the form of a porous network of 173 mesh / inch.
- Tool makers benthos samples for veterinary checks, for example Ekman grap, used for sampling at water sources that flow is relatively small.
Sample containers used can also be made of various materials, but there are some requirements that must be observed sample containers, among others:
- Made of glass or plastic
- Can be closed tightly
- Easily washable and not easily broken
- Containers for the bacteria must be sterilized
- Do not absorb chemicals from the sample
- Not dissolving chemicals into the sample
- Does not cause a reaction between the container and water samples
