Pure silver

Natural bactericide

Silver is a powerful natural bactericide that has been used for thousands of years.

It has very powerful antibacterial properties; the presence of a small part of Silver in a solution is enough to have an effective antimicrobial action.

The Silver ions react and bind with the enzymes of the microbe cell, inhibiting their activity and rapidly bringing them to total extinction while they have no effect on human cells.


The bactericidal properties of silver are excellent for a rapid healing of breast fissures.

Pain reduction

The reduction of bacteria cause a rapid pain reduction caused by fissures.

100% natural

A completely natural treatment without the use of creams or medicines. It also does not alter the flavor of the milk .

Guaranteed quality

Precision Perfection Purity

Pure silver 999‰

New technologies are expected to unlock new solutions to fight and prevent diseases by using material customization on an atomic scale.

Among the most promising materials with antibacterial properties; are metal particles, which exhibit greater chemical activity due to their large surface / volume ratios and crystallographic surface structure.

The study of bactericidal materials is particularly timely considering the recent increase in new strains of bacteria resistant to more potent antibiotics. This has promoted research on the well-known activity of silver ions and silver-based compounds.


The knowledge of the exact silver content in pure silver or silver alloys guarantees the compliance with the quality standards of jewelry and silverware.

Although X-ray fluorescence (XRF) is a quick alternative for establishing the silver content in pure silver and silver alloys, this technique can only establish the percentage of silver in the outermost sections of the metal.

On the other hand, titration represents a more complete solution that considers the entire sample and operates by destructive technique.

Thanks to this technology it is possible to have the potentiometric determination of silver in percentage both in pure silver and in silver alloys.

With this technique it is possible to guarantee the exact percentage of silver of the final product.


Spectrophotometer XRF spectrophotometry (X-ray fluorescence spectroscopy or X-ray fluorescence) is a non-destructive analysis technique that allows to know the elemental composition of a sample through the study of X-ray fluorescence radiation.

This radiation is emitted by the atoms of the sample following excitation (which can also give a photoelectric effect), which is typically obtained by irradiating the sample with high-energy X and gamma rays; analogous effects occur using ion beams.

With this technique it is possible to have a rapid and constant analysis of the product during the various processing phases and to verify that the initial alloy is not altered.


The difference is essentially in the purity of the metal. 925 silver contains only 92.5% silver with the rest made up of other metals (usually copper). 999 silver is instead composed of 999 parts out of 1000 (about 99.9%) of pure silver. This guarantees the best bactericidal action.
The nipple shields are manually punched with the oval mark "999" which indicates the degree of silver purity. Furthermore, to guarantee the title of the precious metal, each production lot is subjected to titration tests and X-rays to confirm its purity.
No, the silver used in PUR999® nipple shields is 100% pure and has not undergone any treatment (rhodium plating, silver plating, gold plating, chrome plating, etc.). For this reason it is completely safe to use.
Because the higher the purity, the higher the effectiveness. No lamination, no galvanic bath, no coating; only pure silver.
