HPLC Mobile Phase Bottles

Description

HPLC Mobile Phase Bottles are specialized containers designed specifically for use in High-Performance Liquid Chromatography (HPLC) systems. They store and deliver the mobile phase, a crucial component that carries the analyte through the chromatographic column for separation and detection.

Features of HPLC Mobile Phase Bottles

• Material: Glass (Borosilicate 3.3): Commonly used due to its chemical inertness and resistance to solvents. Glass bottles are transparent and colorless, or transparent amber, allowing users to monitor the solvent level easily.
• Compatibility: HPLC mobile phase bottles are compatible with a wide range of solvents, including Aqueous solvents (e.g., water, buffer solutions).
  Organic solvents (e.g., acetonitrile, methanol, tetrahydrofuran, ethanol).
• Sizes and Capacities: Typically available in volumes ranging from 100 mL to 10000 mL, depending on the system’s requirements and the duration of the analysis.
• Safety and Sealing: Equipped with airtight caps that minimize evaporation, contamination, and exposure to harmful solvent fumes.

Specialized Mobile Phase Bottle Caps

Multi-Port Caps: Allow tubing to pass through for direct connection to the HPLC system.

The bottle cap is made of superior PP material to ensure high-temperature sterilization, and the PTFE stopper is produced using the finest grade material. The PTFE stopper can be perforated according to customer requirements, with commonly used hole diameters including: 1mm, 2mm, 2.8mm, 3mm, 4mm, 6mm, etc.

Importance of Proper Mobile Phase Bottles in HPLC

• Solvent Purity: Prevents contamination of the mobile phase, which could otherwise compromise the sensitivity and reproducibility of HPLC results.
• Consistent Performance: Protects the HPLC system from particulate damage, clogged columns, and air bubbles, ensuring smooth operation.
• Safety: Minimizes exposure to volatile solvents, reducing health risks and fire hazards in the laboratory.

Best Practices for HPLC Mobile Phase Bottles

• Proper Labeling: Clearly label bottles with the mobile phase composition, preparation date, and expiration date to ensure proper use.
• Avoid Overfilling: Leave sufficient headspace in the bottle to allow for proper mixing and degassing.
• Use of Filters: Always use inline filters or pre-filters to remove particulate matter and prevent system blockages.
• Cleaning and Maintenance: Rinse thoroughly with compatible solvents before use to remove residual contaminants. Clean immediately after each use, especially when switching solvents, to avoid cross-contamination.

By selecting Hawach high-quality mobile phase bottles and adhering to good laboratory practices, you can ensure accurate, reliable, and safe HPLC analyses.
