FAQs

A1: Many cheap PTFE stirrers are simply coated over a steel rod, leaving microscopic pinholes or gaps where the blade attaches. “Full-Sealed Welding” means the PTFE material is seamlessly fused together. This completely eliminates any pores, preventing highly corrosive acids from seeping inside and rusting the inner metal core.

A2: While stainless steel is strong, it can still react with highly aggressive chemicals like concentrated hydrochloric acid or aqua regia, leading to metallic contamination in your sample. Pure PTFE (Teflon) is one of the most chemically inert substances on earth, meaning it will absolutely never react with your chemical solutions.

A3: Yes, absolutely. During vacuum distillation or evaporation, the intense suction and high-speed rotation can cause poorly made stirrer blades to wobble or detach. Our paddle features an exceptionally tight and secure blade-to-shaft connection, ensuring perfect stability even under high vacuum conditions.

A4: No. PTFE has an incredibly low coefficient of friction (it is “anti-adhesive” or non-stick). Even the most viscous, sticky materials like heavy resins, thick paints, or biological slurries will slide right off, making cleanup between experiments incredibly fast and easy.
