Product Features and Material Variety of Sample Vial
Hawach sample vial is made from advanced technology and excellent raw materials. It could be assembled with cap and septa, and use them instantly to save your time. Precise bottle neck size can greatly ensure autosampler handle correctly. What’s more, it is fully compatible with various brands of automatic samplers.
Strict quality control greatly ensures size consistency from batch to batch. It is suitable for Agilent, Waters, varian, Shimadzu, and other brands of autosamplers. For more details, please contact us at any time. Septa and vial have better sealed with improved precision thread, which makes it can be directly closed by hand.
Compared with other septa and cap for sample vials, it can always provide better safety sealing, and can also be used with the wide mouth bayonet sample vials. Furthermore, snap caps preassembled with septa can provide an inert, airtight seal to samples, and present better evaporation resistance with simple thumb pressure.
Hawach provides a 1year warranty for the products we supplied, which can greatly guarantee stable quality. And all the products are certificated, and also meet the SGS test report.
Unique packaging is to reduce sample vial breakage; larger bottle mouth can greatly prevent injection bottle problems; unique thread design can ensure continuous safety seal. Patent design can greatly remove human factors, provide you with the ideal coverage and consistency, and avoid over tightening.
Furthermore, use flat or oblique bottles to provide better tightness. Hawach offers different types of sample vials and matched caps and septa. Almost all the types & sizes of septa are available in Hawach.
Material Variety of Sample vial
Most of the sample vial is made of glass. When it comes to this material, we should first talk about the linear expansion coefficient, which refers to the change of the length of the glass for temperature. In short, the ability of glass to withstandS violent temperature changes. Classification of laboratory glass is based on USP( the American Pharmacopoeia) on its water resistance.
In addition to glass materials, there are other materials: polypropylene (Polypropylene, PP) is a hard material that can be processed into multiple colors and has good chemical tolerance, and is suitable for short-term storage of most laboratory chemicals. When aromatic hydrocarbons or halogenated hydrocarbons are used, their tolerance decreases with time. Because of the high transparency, the sample vials can replace the opaque PP.
The chemical tolerance is similar to that of PP, sample vials are usually used in cases requiring visual samples or high temperature use. sample vials are brittle at room temperature.
Potential Problems of the Sample vial
The importance of the sample vial during the experiment: although the automatic injection bottle may seem irrelevant compared with the many precision analytical instruments used in the laboratory, the wrong use of the injection bottle or cover and pad will have a significant impact on the experiment, resulting in a decrease in the efficiency and repeatability of the experiment.
