Our PTFE Stirring Rods with built-in steel core are professional heavy-duty laboratory stirring accessories, including complete stirrer shafts, stirring rods, paddles and blades. Combining the exceptional chemical stability of pure PTFE and the superior rigidity of internal steel core, these stirring rods solve the flexibility and deformation problems of ordinary pure PTFE stirring tools. Designed for long-term high-temperature and corrosive solution stirring work, they are ideal upgraded labware for chemical stirring, mixing, and homogenization experiments.Steel Core Reinforcement for Maximum Structural Rigidity
Different from traditional pure PTFE stirring rods that are soft and easy to bend or deform at high temperatures, our stirring rods adopt a built-in steel core reinforcement structure. The high-strength steel core provides excellent overall rigidity and structural stability, effectively resisting bending, twisting and vibration during high-speed stirring operation. It maintains a straight and stable working state even in long-time continuous stirring tasks, ensuring uniform liquid mixing and improving experimental consistency and accuracy.
Full Chemical Resistance & 100% Leak-Free Performance
The outer layer is made of high-purity inert PTFE material, featuring excellent full-spectrum chemical resistance. The stirring rods are completely inert to strong acids, strong alkalis, organic solvents and various corrosive chemical solutions, with no chemical reaction, dissolution or contamination. The integrated sealing and wrapping process ensures a completely leak-free structure, effectively preventing internal steel core contact with chemical liquids, avoiding rust, liquid leakage and sample pollution, and protecting both the equipment and experimental samples.
Excellent High Temperature Resistance Up to 280°C
This steel core PTFE stirring rod supports long-term stable operation under high-temperature laboratory conditions, with a maximum working temperature of280°C (540°F). The premium PTFE outer layer can withstand continuous high-temperature stirring work without softening, aging or peeling off. The composite structure maintains stable physical and chemical properties in high-temperature heating, constant-temperature stirring and thermal reaction environments, adapting to various high-temperature experimental processes.
Scratch-Free Smooth Surface Design
The outer PTFE surface is finely polished with a smooth and burr-free finish. It will never scratch glass beakers, flasks, evaporating dishes and other experimental containers during stirring operation. The scratch-free design effectively protects your labware from damage, reduces equipment loss, and avoids glass debris and container abrasives mixing into the sample to affect experimental results. Meanwhile, the non-stick PTFE surface prevents solution adhesion, making cleaning quick and convenient.
Diverse Specifications & Wide Laboratory Applications
Covering stirring rods, complete stirrer shafts, stirring paddles and blades, our steel core PTFE stirring series meets different laboratory stirring and mixing demands. They are widely used in chemical laboratories, pharmaceutical research, environmental testing, food processing, new material development and industrial wet reaction processes, especially suitable for stirring corrosive, high-temperature and high-purity experimental solutions.
