# Colloidal silver (100 ppm) 500 ml - High-dose silver water - Link: https://naturalcure.de/en/colloidal-silver-100-ppm-500-ml-high-dose-silver-water/ - Published: 2026-10-13T12:21:46+02:00 - Author: Kosmetik Shop # Colloidal silver 100 ppm (500 ml): Highly concentrated silver water of laboratory quality With **Colloidal Silver 100 ppm in the 500 ml amber glass bottle,** you receive a **highly concentrated silver water** ( _silver sol_ ) that combines an exceptionally high density of the finest silver nanoparticles with first-class purity. Made from** 99.99% certified fine silver** and multi-distilled laboratory-grade ultrapure water, our dispersion is completely free of chemical stabilizers, proteins, or chlorides. Each batch is freshly produced to ensure a strong electrostatic charge potential. ## What are the distinguishing characteristics of colloidal silver with 100 ppm? ### Physical properties of a highly concentrated silver dispersion In colloid chemistry, **colloidal silver** refers to a heterogeneous dispersion system in which microscopically small, elemental silver particles and silver ions float in highly purified, demineralized water without forming a chemical compound. * **Elemental fine silver instead of chemical salts:** Unlike ionic silver salts( such as silver nitrate), the silver in the electrolytically produced colloid is present as a pure precious metal in nanometer size. * **High zeta potential despite dense particle packing:** At a concentration of 100 ppm, there are twice as many silver particles in the same volume of water as in a 50 ppm dispersion. To prevent the silver clusters, which are only 1 to 15 nanometers in size, from touching and clumping together despite the smaller distance, they possess a similarly charged surface charge ( _zeta potential_ ). They repel each other and remain uniformly suspended due to _Brownian motion_. * **Characteristic golden-yellow to amber tint:** While low-concentration silver water usually appears crystal clear, **genuine colloidal silver at 100 ppm** often exhibits a visible, **slightly golden-yellow to amber tint** . This is not a quality defect, but a physical characteristic of authenticity: The high number of nanoparticles intensifies the so-called _surface plasmon resonance_, in which the particles absorb visible light in the blue spectral range and reflect it with a warm, yellowish hue. Furthermore, a strong scattering cone is visible under focused laser light ( _Tyndall effect_ ). ### What does the specification “100 ppm” mean for a 500 ml volume? The unit of measurement **ppm** stands for _“parts per million”_ and defines the exact mass ratio between the dispersed fine silver and the ultrapure water: * **1 ppm** corresponds to 1 milligram (mg) of silver per 1 liter (kg) of water. * **100 ppm** therefore means that exactly **100 milligrams of pure fine silver are dispersed in one liter of ultrapure water** . * The **500 ml amber glass bottle** therefore contains exactly **50 milligrams of finely dispersed fine silver** . #### Special feature of the concentration level 100 ppm The production of a stable 100 ppm silver colloid without chemical binders requires particularly precise process control. Due to its high concentration, the 100 ppm variant in the economical 500 ml container is suitable wherever a high precious metal density is required in technical or laboratory chemistry applications, or where the colloid needs to be diluted to lower ppm values with type 1 ultrapure water if necessary. ## Production: Fresh daily through precisely controlled electrolysis The higher the desired concentration of a colloid, the more strictly water quality and electrical current must be monitored during production. At **Naturalcure,** colloidal silver at 100 ppm is freshly produced daily in controlled individual batches. ### Controlled electrolysis process without foreign substances * **Fine silver electrodes of the highest quality:** Two electrodes made of certified 99.99% fine silver are immersed in ultra-pure, demineralized laboratory water. * **Gentle separation:** Using an electronically controlled electrolysis process, the smallest electrically charged silver clusters are released from the metal lattice under precisely controlled voltage and dispersed in the water. * **100% pure composition:** Many highly concentrated silver solutions on the market use gelatin, citrates, or proteins (“mild silver protein”) to artificially stabilize high ppm levels. Our 100 ppm colloidal silver is produced using purely physical processes and is **guaranteed free of additives, stabilizers, salts, or preservatives**. ### Our purity and quality criteria * **Certified 99.99% fine silver:** We exclusively use fine silver of the purity grade _Four Nines Fine (999.9)_ , so that no foreign metal ions enter the dispersion. * **Type 1 ultrapure water (Aqua bidestillata):** Multiple distilled and deionized water with a minimal residual conductivity (< 0.1 µS/cm) prevents the formation of unwanted silver salts and ensures the electrical charge balance. * **500 ml amber glass bottle:** Since silver colloids – especially in high concentrations of 100 ppm – are extremely sensitive to light, they are immediately filled into UV-protective pharmaceutical glass. ## Important information on the storage of 100 ppm colloidal silver Because the silver nanoparticles are suspended very close together at a concentration of 100 ppm, the dispersion is particularly sensitive to external disturbances. For a long shelf life, please observe the following storage conditions: * **Protect from light consistently:** Always keep the 500 ml amber glass bottle tightly closed in a dark cupboard. Direct daylight or sunlight leads to discharge( photoreduction) and clumping of the particles. * **Maintain a consistent room temperature (15–22 °C):** **Never store colloidal silver in the refrigerator** and protect it from frost and excessive heat. Cold temperatures slow down Brownian motion, causing the densely packed 100 ppm particles to move closer together and precipitate as a dark sediment. * **Keep away from electromagnetic interference:** To protect the zeta potential of the silver colloids, do not place the bottle near Wi-Fi routers, smartphones, microwaves, power supplies, speakers or induction fields. * **Strictly avoid contamination:** Never allow the liquid to come into contact with metals, plastics, or ordinary tap water. Even the smallest traces of electrolytes or salts can trigger a chain reaction in a 100 ppm colloid and neutralize the charge shell. ## Legal notice regarding classification Colloidal silver 100 ppm (silver water) is supplied exclusively as a technical or laboratory chemical raw material for scientific, analytical, technical, or further processing purposes.
