A straight stirrer is a common laboratory accessory used primarily with overhead stirrers or as a manual mixing tool for low-viscosity liquids. It typically consists of a straight vertical shaft and a simple impeller blade designed for consistent, uniform mixing at medium to high speeds.
Key Characteristics
- Design: Features a straight shaft—often 30cm to 40cm long—with a small-diameter impeller (approx. 6cm to 7cm) at the base.
- Materials: Usually constructed from 316L stainless steel for durability or PTFE-coated (Teflon) materials for superior chemical and heat resistance.
- Usage: Ideal for routine tasks like preparing reagents, dissolving powders, or blending water-like solutions.
Applications:
OS20-S/OS40-S Features:
- Analog speed control with LED real-time display of speed
OS20-Pro/OS40-Pro Features:
- Anti-spill feature: PC control insures smooth acceleration, preventing spills.
- LCD real-time display: Set value and actual value are displayed.
- PC connection via RS232 Port: Allows for PC control and documentation of all measuring values.
