Soil, feed, fertiliser and crop laboratories — sample preparation, drying, moisture, pH and nutrient analysis. Workloads are seasonal, so stock timing matters more than usual. Lab reagents, culture media and everyday consumables: Merck and RCI-Labscan solvents and analytical-grade chemicals, Merck and Difco media, pH buffers and conductivity standards, chlorine and hardness test kits, pipette tips, microtubes, Petri dishes and Whatman filter paper. Send the list with grade and pack size, and we will quote it free on the same quotation as your instruments and glassware.
Suitable for measuring chlorine in aquaculture water, including ornamental fish keeping, and also usable in various industries such as food, beverages, hospitals, and shrimp and poultry farms.

Nitrite in water comes from the decay of organic matter. It is absorbed into aquatic animals through the gills and reacts with haemoglobin in the blood, preventing oxygen transport, causing blood disorders and possibly killing the animals. A nitrite reading above 0.5 mg/l is considered fairly dangerous.
Measures the alkalinity of water. At a suitable level, alkalinity acts as a buffer that keeps pH from changing quickly; low alkalinity lets pH change rapidly, which can endanger aquatic animals. Suitable for testing water in swimming pools, shrimp farms, aquatic plant cultivation and water used in various industries.
Ammonia matters in aquaculture because it is both a toxin for aquatic animals and a fertiliser for phytoplankton growth. At high concentrations it is dangerous to aquatic animals; in culture ponds most ammonia comes from the animals' excretion and leftover feed.
Dissolved oxygen is an indicator of water quality and is important for aquatic animals and plants; too little oxygen in the water can be harmful to them.
The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference…

The HI7051M Soil Sample Preparation Solution is an electrolyte solution used in the measurement of soil pH. The pH of soil is most commonly measured as either a water slurry or electrolyte slurry, where a set ratio of soil:solvent (solvent is water or electrolyte solution) is chosen; common ratios used for soil pH are…
