10 Advantages of Using PTFE Chromatography Vials in Your Lab

Oct. 1st, 2023
Chromatography is an essential technique in analytical chemistry, used to separate, identify, and quantify components within mixtures. For successful chromatographic analysis to occur successfully, using quality vials that contain and protect your samples is key - one such choice being polytetrafluoroethylene (PTFE). PTFE offers several advantages which make them a preferred choice in laboratories; in this article we will outline 10 benefits of choosing PTFE vials in your lab.
1. Chemical Inertness:
PTFE is widely recognized for its superior chemical resistance and inertness to most chemicals - making it a great material to store samples that could interact with other containers, like those made of wood or plastic. Using this material ensures your samples remain uncontaminated or altered during their storage process.
2. Low Adsorption:
A key challenge of chromatography is sample component adsorption to vial surfaces, leading to inaccurate results. PTFE vials boast low surface adsorption properties which significantly lower risk of sample loss or retention.
3. Wide Temperature Range:
PTFE can withstand temperatures ranging from cryogenic temperatures to elevated heat without deforming or breaking down, making PTFE vials suitable for storage samples at various temperatures.
4. Outstanding Sealability:
PTFE vials are known for their superior sealing properties when used with appropriate closures, creating an airtight and leak-proof seal to help avoid sample contamination or evaporation.
5. Transparency:
Although PTFE itself is opaque, many vials come equipped with transparent or translucent lining that allows you to visually inspect sample levels without opening the vial - an invaluable feature for quick sample identification and monitoring.
6. Non-Stick Surface:
PTFE features a non-stick surface, making samples less likely to adhere to its interior walls and making for easier sample recovery with no residue left behind.
7. Longevity:
PTFE is an extremely durable material, making it easier for users to reduce costs over time by not replacing vials as often. Ultimately this durability leads to cost savings over time.
8. Compatibility:
PTFE vials are compatible with many solvents and reagents commonly used for chromatography analysis, providing your samples without an adverse reaction or hindering results.
9. Versatility:
PTFE chromatography vials come in various sizes and configurations, from screw cap vials, snap cap vials, and crimp cap vials to suit any specific application. With such options at your disposal, select the vial type which best meets your requirements for optimal chromatography results.
10. Environmental Friendliness:
PTFE is considered an eco-friendly material due to being non-toxic and recyclable - contributing towards sustainability efforts in laboratories.
PTFE chromatography vials provide numerous advantages that can increase accuracy and reliability in chromatographic analyses. Their chemical inertness, low adsorption properties and wide temperature range make them an excellent choice for many laboratory applications - when choosing vials for your chromatography needs it would be wise to choose those made of PTFE for improved results and cost-efficient laboratory operations.
