In the demanding world of High-Performance Liquid Chromatography (HPLC), precision, safety, and sample integrity are paramount. Uncontrolled solvent vapors pose significant health risks to laboratory personnel, while exposure to air can compromise mobile phase stability and introduce contaminants, leading to inaccurate results and costly re-runs.
Our advanced HPLC Safety Caps are engineered to provide a comprehensive solution, transforming your solvent bottles into sealed, safe, and efficient mobile phase reservoirs and waste containers. Designed for ultimate protection and performance, these caps are an indispensable upgrade for any modern HPLC, UHPLC, or preparative chromatography system.
| Feature | Details |
|---|---|
| Cap Body Material | High-grade Polypropylene (PP) or PPS, chemically resistant and durable. |
| Fittings/Inserts | PTFE (Polytetrafluoroethylene), ETFE (Ethylene tetrafluoroethylene), PEEK (Polyether ether ketone) for ultimate chemical inertness. |
| Filter Medium | Activated Carbon granules with a hydrophobic PTFE membrane for particulate and vapor filtration. |
| Bottle Thread Sizes | Standard GL45 (most common), GL38, S40, and other common laboratory bottle threads available. |
| Number of Ports | Available in 2, 3, 4, or 5 ports to suit various system configurations (e.g., mobile phase inlet, waste outlet, vent, extra solvent line). |
| Tubing Compatibility | Designed for common HPLC tubing outer diameters (OD): 1/16", 1/8", and sometimes larger for preparative systems. |
| Tubing Connection Type | Finger-tight fittings, conical fittings, or specialized connectors for secure and leak-free attachment. |
| Pressure Range | Typically designed for atmospheric pressure systems, but can withstand minor vacuum/pressure differentials common in HPLC solvent delivery. |
| Temperature Range | Operates effectively across standard laboratory temperatures, typically 0°C to 80°C (depending on specific material compositions). |
| Air Inlet Valve | Optional one-way check valve with integrated air filter (e.g., 0.2 µm PTFE) to prevent vacuum build-up and filter incoming air. |
| Filter Lifespan | Varies depending on solvent volatility and usage, often with a visible saturation indicator or recommended replacement schedule (e.g., every 3-6 months). |
