Daihan Stirrer Guide/Seal ptfe 29/42, 8mm SL.ADA406

PTFE Stirrer Guide/Seal for 29/42 ground-glass joints designed to seal and guide an 8 mm diameter stirring shaft during mixing operations. Constructed principally of PTFE with a permanently loaded composite PTFE/PEEK seal and a precision bearing, the device provides a chemical-resistant sealing interface for glass, metal and PTFE stirrer shafts and is intended for use where an aligned, low-vibration seal is required for stirred vessels using a 29/42 joint.

Key Features:

• Material: PTFE (body) with composite PTFE/PEEK seal
• Standard taper ground-glass joint: 29/42
• Fits shaft outside diameter: 8 mm
• Sealing/bearing design: permanently loaded PTFE/PEEK seal with precision bearing
• Performance: vacuum (~5 mm Hg) and pressure (3–5 psi) capability
• Recommended maximum speeds: continuous 500 rpm, intermittent 800 rpm

Advantages:

• High chemical resistance from PTFE construction for broad laboratory compatibility
• Anti-whip design and precision bearing reduce vibration and improve shaft alignment
• Capable of vacuum and light-pressure operation to support sealed mixing applications
• Composite PTFE/PEEK loaded seal provides durable sealing with minimal shedding and a self-releasing joint ring
