Vortex Stirrer

Vortex Stirrer

Vortex Stirrers are specially designed for high-shear mixing and rapid agitation in glass reactors, beakers, and process vessels. They produce a vortex flow, ensuring efficient mixing, suspension of solids, and homogenization.

The Vortex Stirrer is ideal for creating a downward spiral flow, which pulls liquid from the surface to the bottom of the vessel. This design is perfect for mixing suspensions, dissolving solids, or accelerating chemical reactions.

• Borosilicate glass shaft ensures thermal and chemical resistance
• PTFE or Teflon blades for inertness and durability
• Suitable for low to medium viscosity liquids
• Works with vacuum, low-pressure, and atmospheric systems
• Compatible with standard stirrer drives and motor assemblies

FAQs – Vortex Stirrer

Q1: What viscosity range can a vortex stirrer handle?
A: Suitable for low to medium viscosity liquids, generally <1000 cP.

Q2: Can it mix solids effectively?
A: Yes, the vortex flow suspends solids and ensures homogeneous mixing.

Q3: Are the blades replaceable?
A: Yes, blades are modular and can be replaced individually.

Q4: What kind of flow does the vortex stirrer generate?
A: Downward spiral flow, drawing surface liquid to the bottom for complete circulation.
