Detailed Product Description
Our filter basket is manufactured using advanced weaving and welding techniques to ensure uniform mesh opening and structural integrity. The 0.3mm mesh is tightly woven to prevent particle bypass while allowing efficient liquid flow. The basket body is formed from 304 stainless steel sheet with a thickness typically 1.0mm to 2.0mm, providing rigidity and resistance to deformation under pressure. All welds are ground smooth and passivated to maintain the sanitary finish. The basket is available with a solid bottom or fully meshed design, depending on your filtration requirements. For pharmaceutical applications, we offer an electropolished finish that reduces surface roughness and improves cleanability, meeting the requirements of FDA and GMP guidelines (note: certifications are available upon request; please contact us for details).
Advantages Over Standard Filter Baskets
- Superior corrosion resistance in acidic or alkaline pharmaceutical solutions.
- Reduced risk of product contamination due to smooth, non-porous surface.
- Easy to clean using CIP (Clean-in-Place) or SIP (Sterilize-in-Place) systems.
- Longer service life compared to carbon steel or lower-grade stainless baskets.
- Customizable handle length and type for ergonomic handling.
Applications
- Filtration of pharmaceutical intermediates and APIs.
- Clarification of syrups, suspensions, and injectable solutions.
- Pre-filtration before membrane filtration systems.
- Straining of herbal extracts and tinctures.
- Use in bioreactors, fermenters, and storage tanks.

Frequently Asked Questions (FAQ)
Q1: What is the standard mesh size available? Can I get other mesh sizes?
A: The standard mesh is 0.3mm opening. We also offer custom mesh sizes from 0.1mm to 2mm upon request. Please provide your required particle retention size.
Q2: Is the sanitary finish suitable for sterile applications?
A: Yes, the Ra ≤ 0.8μm finish is suitable for cleanroom environments and can be further electropolished to Ra ≤ 0.4μm for higher sterile requirements. Steam sterilization at 121°C is supported.
Q3: How do I choose the correct connection type?
A: The most common connection for pharmaceutical systems is tri-clamp (sanitary clamp). We also offer flanged, threaded, or custom connections. Provide your existing piping details for a perfect fit.
Q4: What is the maximum operating temperature and pressure?
A: Continuous operating temperature is up to 120°C. Maximum pressure depends on basket dimensions, typically up to 10 bar. For higher pressure, we recommend a reinforced design.
Q5: Can I get a filter basket with a handle or a lid?
A: Yes, handles are available (fixed or foldable) and can be customized in length. A lid is optional for applications requiring a closed system.
Q6: How do I clean the filter basket?
A: The basket can be cleaned using ultrasonic cleaning, high-pressure water, or CIP systems. The smooth surface prevents particle adhesion. Avoid using abrasive tools that may scratch the surface.
Q7: Do you provide samples before bulk order?
A: Yes, we offer samples for evaluation. Please contact our sales team with your requirements. Sample cost is negotiable, and shipping charges apply.
Q8: What is the lead time for custom orders?
A: Lead time is typically 15-25 working days after design confirmation, depending on complexity and quantity. Rush orders can be accommodated.
