Silicates are mineral components that can be dissolved in water and can cause deposits in pipework and medical devices at higher concentrations. Monitoring the silicate content in water is therefore an essential part of water treatment in clinics and hospitals. Deposits caused by silicates can significantly affect the efficiency of water supply systems and, in the worst case, lead to blockages, which is particularly problematic in medical care.
High silicate levels can reduce the functionality and longevity of water treatment systems, as mineral deposits reduce the permeability of pipes and increase maintenance costs. In an environment such as a hospital, where the water supply must be guaranteed around the clock, it is particularly important to monitor the silicate level. Silicates can build up in the systems as poorly soluble deposits and thus disrupt the operation of the water treatment systems.
By regularly monitoring and measuring the silicate level in the water, medical staff can ensure that the water quality meets the highest standards at all times. Controlling the silicate content contributes to the efficiency of water treatment and prevents long-term deposits in water-bearing systems, which is particularly important in sensitive areas such as clinical care.
Refill pack: 1 set of TESTOVAL Silicate reagents for rapid manual analysis of the silicate content in water in the concentration range 0–10 mg/l SiO2. The individual values 0.25 mg/l, 0.5 mg/l, 1 mg/l, 2.5 mg/l, 5 mg/l and 10 mg/l can be read by optical colour comparison. By diluting the water sample in a ratio of 1:10 with distilled water, the measuring range can be extended to 10 times the concentration. The scope of delivery includes only test reagents A, B, C and D for simple concentration determination. 1 set of reagents Measuring time: approx. 19 minutes Analyses: approx. 100 Also available in the shop: Complete TESTOVAL dissolved silicate test kit: Order no. 410622 Replacement silicate colour comparison device: Order no. 410624
Testoval Silicate Test Kit – Color Comparison for Rapid Analysis Reliable manual determination of dissolved silicate in water The Testoval Silicate Test Kit is designed for rapid, manual analysis of silicate content in water in the concentration range of 0–10 mg/l SiO₂. Individual values of 0.25 mg/l, 0.5 mg/l, 1 mg/l, 2.5 mg/l, 5 mg/l, and 10 mg/l can be read using a visual color comparison. When reagents are added to the water sample, a characteristic color develops. The provided comparison scale allows easy reading of the concentration levels. By diluting the sample 1:10, the measurable range can be extended by a factor of 10. The kit allows for approximately 100 individual analyses, with each measurement taking about 19 minutes. Manual determination of dissolved silicate in water up to 10 mg/l The Testoval Silicate Test Kit enables reliable, manual analysis of dissolved silicate (SiO₂) in water. After adding the reagents, a characteristic color reaction occurs, which is evaluated using the included comparison scale. Diluting the water sample 1:10 allows flexible extension of the measurement range by a factor of 10. Why monitoring silicate in water is important Dissolved silicates play a crucial role in industrial water treatment, particularly in boiler feed water, cooling water, and reverse osmosis systems. Excessive silicate concentrations can lead to the formation of stubborn deposits (silicate scale), which are difficult to remove and significantly impair heat transfer and system efficiency. In membrane processes, silicate can also cause irreversible damage and significantly shorten membrane lifespan. Regular silicate monitoring allows early detection of limit exceedances, targeted process control, and prevention of costly system damage. The Testoval Silicate Test Kit thus supports safe process management and long-term operational reliability.
