PTFE Siringe, Jarum suntik, 100 ml
Rp123.00
Our PTFE syringe is a specialized laboratory syringe used for dispensing and handling highly corrosive or aggressive chemicals that would damage standard glass or plastic syringes.
Key Benefits:
Universal Chemical Resistance: PTFE is resistant to virtually all acids, bases, and organic solvents, including hydrofluoric acid. This prevents the syringe material from degrading or contaminating the sample.
High Purity and Low Extractables: The use of high-purity virgin PTFE ensures minimal leaching of contaminants into the dispensed liquid, which is critical for sensitive analytical techniques like HPLC and GC analysis.
Durability: Unlike glass syringes, PTFE models are shatterproof and highly impact-resistant, increasing safety and longevity in the lab.
Wide Temperature Range: They can operate across a broad spectrum of temperatures, typically from -200°C to +250°C.
Non-Stick Surface: The non-stick properties of PTFE allow for smooth operation and ensure complete sample transfer and easy cleaning.
Primary Applications:
Filtering Aggressive Solvents: PTFE syringe filters are the most common application, where a disposable filter membrane in a polypropylene housing is attached to a standard syringe to filter harsh chemicals or organic solvents prior to analysis. They are used for:
HPLC Sample Prep: Removing particulates to protect expensive chromatography columns.
Gas Filtration: The hydrophobic nature of PTFE makes it ideal for filtering air and gases to exclude moisture.
Environmental Testing: Processing samples where chemical resistance is essential for accurate pollutant analysis.
Dispensing Corrosive Liquids: Full-bodied PTFE syringes are used to draw up and safely dispense concentrated acids or bases, such as hydrofluoric acid, which cannot be handled by glass syringes.
