About HAWACH Silanization Glass Sample Vials
As we all know, Hawach is a very famous scientific company, which produces quality scientific products for experiments and biotechnology. It has a reputation in the International market. So why does it enjoy such great popularity? First, we can see one of its great products, sample vials.
With the rapid development of material separation, computer, precision processing, mechanical manufacturing, automation, and other technologies, sample processing technology is constantly enriched and innovated, and the selection of sample bottles is also different. Let’s introduce it now.
Cute appearance:
There are many vials with totally different cute appearances in Hawach. Designers must have racked their brains when they design the vials. Because they need to think of appearance and practicability. Each of them is not only just a vial but also a piece of artwork.
Silanization
The silylation treatment is a process in which a metal or non-metal material is surface-treated with an aqueous solution of an organosilane as a main component. Compared with traditional phosphating, silanization has the following advantages: no harmful heavy metal ions, no phosphorus, and no need for heating.
The silane treatment process does not produce sediment, featuring short treatment time and easy control. The fewer processing steps save the surface adjustment process, and the bath can be reused, which effectively improves the adhesion of the paint to the substrate. A variety of substrates such as iron plates, galvanized sheets, and aluminum sheets can be processed in a collinear manner.
HAWACH Silanization glass sample vials
The HAWACH silanized glass vials were treated by vapor phase deposition silanization. Surface passivation treatments such as silanization and solicitations are critical to maintaining the integrity of certain materials or extracts stored in glass containers. The surface modification reduces the active site on the surface of the borosilicate glass.
1. Silanization saves time and minimizes waste costs when performing quantitative analysis or storage of materials.
2. The silylating agent reacts with the reactive groups on the surface of the glass to reduce its activity; preventing the material from adhering to the surface of the container, thereby maximizing the recovery of trace analytes.
Sort of vials:
At present, Hawach concentrates on producing these following vials, with the most professional and advanced technique.
Crimp top sample vials.
Headspace vials.
Screw thread top sample vials.
Snap top sample vials.
Storage vials.
Besides, it also produces septa and cap for crimp top sample vials, septa and cap for screw thread sample vials, septa and cap for snap vials.
Selection according to the type of sample vial
The types of sample bottles are sample bottles with clamp caps, sample bottles with thread caps and sample bottles with clamp caps. The jaw cap bottle is inexpensive but requires a jaw tool, and the cap can not be reused. Sample bottles with threaded caps can be reused and are not volatile.
Selection according to the material of sample vial
1. Glass-universal and acid-resistant;
2. Brown bottle – for photosensitive samples;
3. Silanization/deactivation-for sample and trace analysis easily bonded to a glass bottle wall;
4. Polypropylene – for alcohol samples or water-soluble solvents;
5. Micro living tube – for very little sample introduction;
6. High yield – for a limited sample size.
These are the classification and material characteristics of sample vials. When choosing sample vials, users can choose according to their own needs and the characteristics of products.
