School Kit for Water analysis with Water Sampler

MACHINE TRANSLATION (not authorised yet)

New! Now a professional Macherey Nagel's Water Analysis Case with a professional Water Sampler!

VISOCOLOR Eco, school reagent case, is a handy set designed for quick and simple water analysis.
The set is especially designed for schools as a compact mini lab with easy test procedures, and safe results, flexible applications and inncredible educational value. It also caters to the needs of both students and teachers.

All reagents can be used in schools and if not regulated otherwise in some countries or places, they can be disposed off easily just down the drain without any harm to the environment.
The case contains 6 colorimetric and titrimetric tests for at least 50 determinations each to determine the most important water parameters Ammonium, Total Hardness, Nitrat, Nitrit, pH, Phosphat (ortho):
Ammonium 0.2–3 mg/L NH 4+
Nitrate 1–90 mg/L NO3–
Nitrite 0.02–0.5 mg/L NO2–
Phosphate 0.5–15 mg/L PO43–
pH 4.0–9.0
Total hardness 1 drop = 17.8 mg/L CaCO3
The newly developed tests are based on Macherey-Nagel's proven system and were developed as high quality VISOCOLOR® SCHOOL test specifically for schools.

VISOCOLOR® SCHOOL reagent case includes all necessary reagents and accessories for determining ammonium, total hardness, nitrate, nitrite, phosphate and pH, manual and colour scale.

Features
• Maximum safety due to exact labeling of all reagents
• Safe results using colour and turbidity compensation
• Especially stable and rugged case as well as chemical resistant foam inlay
• High sensitivity down to the values of German drinking water standards
• Safe for the environment and easy disposal of used tests

Other features
Shelf life (from production): 1.5 Year(s)
Storage temperature: 15–25 °C
Scope of delivery: Case, test kits, accessories, instructions
Hazardous material: Yes

Additional elements of the set are: 25 ml beaker, syringes, colour separators, colour chart. The whole set is in a rigid plastic case with a handle.

The use of the Visocolor Eco, school set, thanks to simple environmentally friendly methods, gives the opportunity to quickly check the water quality, so that we get an excellent collection of information on the properties of the water sample tested.
We recommend also due to the quality of reagents supplied by a renowned German company Macherey-Nagel. The reagents are of high sensitivity, colour compensation and turbidity.
The kit is specially dedicated for use in schools.

Now offered as a set with a professional Water Sampler that enables water sampling from the expected depth. This is a professional water sampler with a thermometer and a line and ball mechanism automatically opening and closing the sampler, designed to take water samples from a specific depth.

Water Sampler is designed to collect approximately 1000 mL of sample water. The sampler is attached to a line, making it possible to take a sample at a specific depth. The weight of the sampler insures a rapid descent which minimizes drift resulting from water
currents. A special ball mechanism is activated to collect the sample at the chosen depth, when at the same time the sampler covers prevent the collected water sample from mixing with intermediate layers of water on the way back to the surface.

Thanks to its practical design it is a user-friendly device. Measured temperature range -10oC...+50oC. The thermometer is fixed inside and indicates the temperature of the sample flowing through the sampler's transparent chamber. The sampler is equipped with tap which prevents the sample from mixing and contaminating with atmospheric oxygen. The instrument is made of strong PVC and metal. Supplied with a 20-meter long nylon cord rolled up on the handle ended with a snap hook. Length of the sampler: 37 cm.

How to use the sampler?
1) Lower the water sampler to the depth desired in the chosen waterbody. As the sampler sinks the ball valves open and allow water to flow through the cylindrical chamber.
2) When the water sampler reaches the desired sample depth, the nylon line should be pulled three times to move the water sampler ca. 30 cm up and down the water column to eliminate any water remainings from previous depths.
3) Pull the water sampler out of the water and take the sample from the chamber using the tap.
4) The temperature should be read immediately after pulling the water sampler out of the waterbody.

Length: 37 cm.
