Batang pengaduk merupakan sebuah peralatan laboratorium yang digunakan untuk mencampur bahan kimia dan cairan untuk keperluan laboratorium. Biasanya terbuat dari kaca pejal, dengan dengan ukuran hampir sama dengan sedotan minum, hanya sedikit lebih panjang dan ujungnya membulat.
Our PTFE stirring paddles are specialized components of mechanical overhead stirrer systems, designed to provide superior chemical resistance and durability compared to traditional glass or metal options.
They are generally used with a shaft that connects to a motorized stirrer, allowing for robust and controlled mixing of a wide range of laboratory materials.
Key Benefits:
Universal Chemical Inertness: PTFE (Teflon) is resistant to almost all laboratory chemicals, including strong acids (like hydrofluoric and nitric acid), strong bases, and organic solvents.
Wide Temperature Range: Suitable for use in reactions from cryogenic temperatures up to approximately 250°C.
Durable Construction: Often feature a stainless steel core encapsulated in PTFE for mechanical strength and rigidity, preventing the fragility issues of all-glass paddles.
Non-Stick Surface: The low-friction surface minimizes material adhesion and simplifies cleaning, reducing the risk of cross-contamination.
Laboratory and Research Applications:
Corrosive Substance Handling: A primary application is the safe mixing of strong acids, bases, and organic solvents, especially those that would corrode or damage glass or metal stirring rods. This includes working with hydrofluoric acid, aqua regia, and concentrated sulfuric acid.
Trace Element Analysis: In sensitive analytical techniques like ICP-MS, PTFE paddles are essential for sample preparation to prevent the leaching of metal ions from traditional glass or metal equipment that could introduce errors in the results.
High-Purity Synthesis: Used in organic synthesis and research where maintaining the purity of the compounds is critical for experimental success and preventing unwanted side reactions.
High/Low Temperature Reactions: The wide temperature stability of PTFE (from cryogenic up to 250°C) allows these paddles to be used in temperature-controlled reactions that might be too extreme for other plastic or glass stirrers.
Industrial and Manufacturing Applications:
Chemical Manufacturing: Extensively used in large-scale reactors and mixing tanks for producing a wide range of chemical formulations, ensuring uniform dispersion and consistent reaction outcomes.
Pharmaceutical and Biotechnology: Employed for preparing medicinal compounds, diagnostic reagents, and cell cultures, where a non-reactive, easy-to-clean, and sanitary surface is required to prevent contamination and bacterial growth.
Food and Beverage Processing: Utilized in food-safe applications for mixing sauces, dressings, and dairy products. The non-stick properties of PTFE ensure the purity of the final product and facilitate easy cleaning to meet strict hygiene standards.
Semiconductor Manufacturing: Used in wet process equipment for wafer cleaning and etching where aggressive chemicals are used and zero contamination is tolerated.
