Polar compounds like amino acids, proteins, or phenols can react with an untreated glass surface causing serious complications when performing quantitative analysis or storing materials. To help our customers remedy this problem, Glass Vials now offers silanized glassware. This treatment discourages any interaction between biological compounds and the glass and inhibits materials from adhering to the surface of the container, allowing for maximum recovery of trace analyte.
GLASS TREATMENT OPTIONS:
Glass Vials – Silanizing SS2
A popular treatment for glass is silanization. This is a very rudimentary surface treatment for glass, and simply involves attaching silanols to the surface of glass, usually using silanes or chlorosilanes. These procedures can help to keep the glass clean over several washes and help to prevent materials from sticking to the glass. However, fundamental silanizing is crude and not very durable. We do not use the same pathway as standard methodology. Our method provides a completely uniform treated surface, and we can tailor the surface hundreds of ways to best fit your needs.
Glass Vials – 18 c, f SS1
This treatment provides a low surface energy, i.e., Hydrophobic and lipophobic, that resists non-specific protein binding and is non-hemolytic and non irritating. This method is a full-contact FDA rating and is safe for surgical or food use, as well as being safe for biological samples. It is stable in all common solvents and most chemicals. and will help prevent scratching and reduce the possibility of the closure sticking to the bottle. The method not recommended for long term use in high pH conditions and environments such as commercial detergents. Glass Vials–18 can be applied in three formulations, C, F, and mixed; specifying Glass Vials–18 is typically a mixed formulation.
Scratch and Haze Repair Coatings
There are two methods to reduce the appearance of scratched glass. One method is to fill in the scratches with a transparent material that has a similar refractive index to glass. With this method, the irregularities are smoothed out, leaving less visible scratches and less haze. The downside to this method is the coating itself can become scratched with rough handling.
The second method treats the scratches themselves, and changes the way light reflects from the scratches, making the scratches less visible and more like the unscratched glass. The scratches are still there, just less visible. This method may not be suitable for applications where the bottle is being used in optical instruments which “look through” the glass, such as in a spectrophotometer; the coatings of this type tend to attenuate certain wavelengths of light.
Glass Vials – pH Surfaces
The pH Surfaces was designed to provide a neutral pH surface for specific applications. Fresh clean glass from manufacturing may have a slightly acidic component which can be detected by instruments. Old glass or glass that has been heated or even washed in certain detergents can have a basic or high pH component. We can apply a uniform surface treatment that has non-reactive and has insoluble properties, which make the pH of the glass a neutral 7.0, and the treatment will retain that property.
Glass Vials – encapsulation (deactivation)
We can completely coat the glass in a protective, non-reactive surface which will stop any chemical interaction with the materials inside the vial. It is perfect for archival applications. This method is resistant to all common solvents, is extremely insoluble in water, and does not harm blood or sensitive biological samples. We can do this with various reactive silicones, or with bondable inert materials.
