High quality wholesale 2ml sample vials for sale

In the delicate world of laboratory science, the 2ml sample vials play a crucial role. These tiny, sophisticated vessels are not only the cornerstone of chemical analysis, but also the embodiment of technological progress and experimental efficiency. This article will delve into the physical specifications, design features of 2ml sample vials, and how they ensure seamless integration with modern automated sampling systems, revealing the value of 2ml sample vials in scientific research and industrial applications.
Exquisite design of physical specifications
The 2ml sample vials, with compact volume of 12 x 32 mm, become indispensable tool in the laboratory. This size is not only easy to operate, but also ensures efficient storage and transportation. The diameter and height of the bottles are carefully calculated to ensure sufficient capacity to accommodate a variety of types and to ensure great layout in a limited space, which is particularly important for laboratory space management.
Scientific considerations for screw design
The Screw design is a key feature of the 2ml sample vials, which uses standard threads such as the common Screw Thread 8-425 or HPLC-specific threads, which not only guarantees seal reliability, but also ensures compatibility with various automatic samplers. The precision of the screw is critical, as it needs to fit closely to the matching cap to prevent sample volatilization, contamination or leakage, especially during prolonged analysis or under severe temperature conditions. The standardization of this design allows the laboratory to easily replace different brands or models of sample bottles without worrying about compatibility issues, greatly improving the flexibility and efficiency of the laboratory.
The partner for an automatic sampler
Automatic sampler is the core technology in modern chromatographic analysis, and the 2ml sample vials are designed to meet this demand. Its size and shape are optimized to ensure stable placement on the automatic sampling tray, reducing errors during sampling. The standardization of the screw design ensures that the bottle can be firmly fixed under the injection needle, avoiding any displacement during high-precision sampling. In addition, the shape of the bottle is designed to take into account the depth of insertion of the automatic injection needle, ensuring that the sample can be accurately drawn every time, which is crucial for the repeatability and accuracy of the analysis.
The wisdom of material selection
2ml sample vials are usually made of high-quality borosilicate glass or plastic (e.g., polyethylene, polypropylene). Borosilicate glass is preferred for its low coefficient of thermal expansion and chemical resistance, especially for samples requiring long-term storage or sensitivity to light. Plastic sample bottles are cost-effective and lightweight, and are suitable for single-use or where there are special safety concerns about glass. The choice of material is directly related to the protection of the sample and the accuracy of the analysis results.
Improved laboratory efficiency
In high-throughput analysis, the standardized design of the 2ml sample vials simplifies the sample preparation process, reduces manual time, and improves the continuity and automation of the experiment. The combination of the automatic sampler and these vials allows the laboratory to handle a large number of samples, and a wide range of application scenarios, from drug development to environmental monitoring, benefit from the efficiency of this design.
conclusion
2ml sample vials, this seemingly insignificant laboratory consumable, is actually an indispensable precision tool in scientific experiments. The exquisite design of the physical specifications, the compatibility of the screw and the integration with the automatic sampling system form the basis of an efficient, accurate and flexible analysis system. In the pursuit of higher experimental accuracy and efficiency today, the design concept and practical application of 2ml sample vials undoubtedly reflect the integration of science and engineering, providing solid support for scientific researchers and promoting the development of laboratory science.
