Rocker Filter Holders For Precise and Efficient Filtration
Rocker's range of filter holders is engineered for reliability and ease in laboratory filtration. Designed for a wide range of applications, they ensure consistent sample integrity and efficient filtration for researchers and labs handling multiple samples daily.
Key Features
Comparison of PES, PPSU, Glass, and Stainless Steel filter holder materials, focusing on advantages and suitability for different applications:
PES (Polyethersulfone): Known for its chemical resistance, ideal for biological and pharmaceutical filtrations.
PPSU (Polyphenylsulfone): Offers superior thermal resistance and mechanical strength, suitable for high-temperature sterilization.
Glass: Chemically inert and transparent, perfect for visual inspection but fragile.
Stainless Steel: Highly durable, autoclavable, and ideal for aggressive chemicals, often used in industrial or harsh lab environments.
Selection Guide
Key Considerations
Sample Volume: Choose a holder with a suitable membrane diameter and funnel capacity to accommodate your sample size.
Chemical Compatibility: Select a material resistant to the chemicals you are working with. Consult a chemical compatibility chart to determine the best material.
Handiness: Consider ease of use and handling. PES is the easiest to handle or most user-friendly material, followed by Glass, and Stainless Steel.
Sterilization Needs: If autoclaving is required, stainless steel and PES are ideal choices, with stainless steel being the most robust.
Material Advantages
PES: Excellent chemical resistance, ideal for biological/pharmaceutical applications.
PPSU: Offers excellent resistance to a wide range of chemicals, including solvents, along with superior heat resistance and mechanical strength.
Glass: Chemically inert, transparent for visual inspection, but fragile.
Stainless Steel: Durable, autoclavable, ideal for aggressive chemicals and harsh environments.
Application Guidance
Chemical Compatibility: Consider the chemicals involved in filtration.
Sterilization: For high-temperature autoclaving, choose PPSU or stainless steel.
Sample Sensitivity: Use glass or PES for delicate biological samples.
Durability: Stainless steel is best for demanding or repetitive use.
