Overview
The BASIK™ Mobile Phase Filter Degasser is designed to remove particulate matter and dissolved gases from HPLC mobile phases before they enter the chromatographic system.
When operated under vacuum, the system helps:
- Remove particulate contaminants
- Reduce dissolved oxygen
- Reduce dissolved carbon dioxide
- Improve mobile phase quality
- Support consistent chromatographic performance
Although the unit incorporates a sintered glass support filter, additional components are required for proper operation.
Required Membrane Filters
A disposable membrane filter disc must always be installed during use.
Compatible Filter Sizes
- 47 mm diameter membrane filters
Available Pore Sizes
- 0.22 µm
- 0.45 µm
Selection should be based on laboratory procedures and filtration requirements.
Available Membrane Materials
Nylon Membranes
Commonly used for:
- Aqueous mobile phases
- Organic solvents
- General-purpose HPLC filtration
PTFE Membranes
Commonly used for:
- High organic solvent content
- Normal Phase chromatography
- Aggressive solvent systems
Membrane filters are supplied separately from the degasser assembly.
Vacuum Source Requirements
The BASIK™ Mobile Phase Filter Degasser requires a vacuum source to perform degassing and filtration.
Acceptable options may include:
- Laboratory vacuum pumps
- Central laboratory vacuum systems
- Dedicated filtration vacuum systems
The selected vacuum source should be appropriate for use with laboratory glassware and compatible with the operating requirements of the filtration system.
Vacuum Tubing Requirements
Suitable vacuum tubing is required to connect the degasser assembly to the vacuum source.
The tubing should provide:
- Secure vacuum connections
- Chemical compatibility
- Adequate vacuum performance
Users should select tubing appropriate for their laboratory vacuum system.
Glassware Safety Considerations
Because the BASIK™ Filter Degasser is constructed from glass, the vacuum source should be properly regulated.
Excessive vacuum levels may:
- Place unnecessary stress on the glass assembly
- Reduce equipment life
- Increase the risk of glass breakage
Always follow laboratory safety procedures and vacuum equipment recommendations.
Typical Applications
The BASIK™ Mobile Phase Filter Degasser is commonly used for:
- HPLC mobile phase preparation
- Solvent filtration
- Solvent degassing
- Mobile phase reservoir preparation
- Routine chromatography laboratory operations
Proper filtration and degassing can help improve system performance and reduce chromatography-related issues.
Recommended System Components
For complete operation, the following components are recommended:
- BASIK™ Mobile Phase Filter Degasser
- 47 mm membrane filter discs
- Appropriate vacuum source
- Vacuum tubing
- Suitable solvent reservoir containers
Together, these components form a complete mobile phase filtration and degassing system.
Key Takeaways
- The BASIK™ Mobile Phase Filter Degasser requires disposable 47 mm membrane filters.
- Filter pore sizes of 0.22 µm and 0.45 µm are available.
- Nylon and PTFE membrane options support different solvent systems.
- A dedicated vacuum source and vacuum tubing are required.
- Proper vacuum control helps protect the glass filtration assembly.
- The system is designed to both filter particulates and remove dissolved gases from HPLC solvents.
