PATIKIL 20ml Glass Vials 100 Pack Autosampler Screw Top Borosilicate

Description

Product Overview

The PATIKIL 20ml clear glass vials are engineered for demanding laboratory environments where precision, durability, and chemical resistance are essential. Constructed from premium borosilicate glass, each vial offers exceptional thermal stability, allowing it to withstand repeated heating cycles without compromising structural integrity. The transparent body provides unobstructed visual inspection of sample volume and condition, while the 19.5mm outer diameter mouth ensures compatibility with a wide range of autosampler instruments. Each vial is sealed with an iron screw‑top cap that creates a reliable, leak‑proof closure, protecting samples from contamination and evaporation. The flat‑bottom design maximizes sample stability during centrifugation and vortexing, and the 20 ml capacity strikes a balance between sufficient volume for analytical procedures and efficient use of storage space. Packaged in a convenient 100‑piece case, these vials are ready for immediate deployment in high‑throughput workflows.

Usage

These vials are ideally suited for a broad spectrum of analytical techniques, including high‑performance liquid chromatography (HPLC), gas chromatography (GC), liquid chromatography‑mass spectrometry (LC/MS), and headspace analysis. Their chemical inertness makes them compatible with acidic, neutral, and alkaline reagents, ensuring sample integrity across diverse assay conditions. In pharmaceutical research, the vials serve as reliable containers for stability testing, dissolution studies, and impurity profiling. Environmental laboratories benefit from their robustness when analyzing water, soil, and air samples, especially in headspace sampling where airtight sealing is critical. The screw‑top caps facilitate rapid loading and unloading on automated autosamplers, reducing turnaround time and minimizing manual handling errors. Additionally, the vials can be employed in routine sample storage, preparation of calibration standards, and quality control checks within any certified laboratory setting.

Why Choose Us

Choosing PATIKIL means selecting a brand committed to scientific excellence and rigorous quality control. Every vial undergoes a multi‑stage inspection process that includes dimensional verification, visual clarity assessment, and leak testing to guarantee consistent performance across the entire batch. The borosilicate composition is sourced from reputable manufacturers, providing superior resistance to thermal shock and chemical attack compared with standard soda‑lime glass. Our iron screw‑top caps are precision‑machined to deliver a uniform torque, ensuring a consistent seal that prevents sample loss during prolonged storage or high‑speed centrifugation. We also offer responsive technical support and a clear return policy, giving laboratories confidence that any issues will be addressed promptly. By integrating these vials into your workflow, you benefit from reduced assay variability, enhanced reproducibility, and compliance with industry standards for analytical instrumentation.

FAQ

What types of samples can I store in these vials?

The vials are compatible with a wide range of liquid and gaseous samples, including acidic, neutral, and alkaline solutions, as well as volatile compounds used in headspace analysis. Their chemical inertness ensures that the container does not interact with the sample.

Are the vials compatible with all autosampler models?

Yes, the 19.5 mm outer diameter mouth and standard screw‑top design conform to the specifications of most major autosampler manufacturers, making them suitable for HPLC, GC, and LC/MS systems.

How do I ensure a proper seal after crimping?

After placing the sample, tighten the iron screw‑top cap until it is snug but not over‑torqued. Visually inspect the cap to confirm it sits flush against the vial mouth, and perform a quick leak test by gently inverting the vial.

Can these vials be used for high‑temperature applications?

Absolutely. Borosilicate glass can tolerate repeated heating cycles up to 350 °C, making the vials suitable for procedures that involve heating, such as derivatization or thermal desorption.

What is the recommended storage condition for the vials?

Store the vials in a cool, dry environment away from direct sunlight. For long‑term storage, keep them sealed with the caps in a clean, dust‑free cabinet to maintain sample purity.
