1. Pitch Blade Stirrer – SS316L Lab Grade
Description: Pitch blade stirrers feature blades angled typically at 45°, promoting axial flow, which moves materials from the top to the bottom of the vessel.
Material: Made from SS316L stainless steel, known for its corrosion resistance and suitability for laboratory environments.
Applications:
- Ideal for mixing low to medium viscosity fluids.
- Commonly used in blending, solid suspension, and heat transfer processes.
Advantages:
- Efficient axial flow enhances mixing.
- Durable and resistant to corrosion.
2. Anchor Blade Stirrer – SS316L Lab Grade
Description: Anchor blades are designed to sweep close to the vessel walls, ensuring thorough mixing, especially in viscous materials.
Material: Constructed from SS316L stainless steel, offering strength and corrosion resistance.
Applications:
- Suitable for high-viscosity fluids like gels and creams.
- Effective in processes requiring minimal shear.
Advantages:
- Ensures uniform mixing by scraping vessel walls.
- Reduces dead zones in mixing.
3. PTFE Blade with Glass Rod
Description: This stirrer combines a chemically inert PTFE blade with a glass rod, making it suitable for sensitive applications.
Material: PTFE (Polytetrafluoroethylene) blade attached to a borosilicate glass rod.
Applications:
- Ideal for mixing corrosive chemicals or sensitive reactions.
- Common in synthetic laboratories and when purity is paramount.
Advantages:
- Excellent chemical resistance.
- Non-reactive and maintains sample integrity.
Comparison Summary:
| Feature | Pitch Blade SS316L | Anchor Blade SS316L | PTFE Blade with Glass Rod |
