Magnetic Stir Bar 8pcs 30mm PTFE Coated White – Ckepvo Lab Stirrer

Description

Product Overview

The Ckepvo Magnetic Stir Bar set delivers professional‑grade performance in a compact, easy‑to‑handle package. Each of the eight 30 mm stir bars is finished in a clean white hue and encapsulated in a high‑quality PTFE (polytetrafluoroethylene) coating. PTFE is renowned for its chemical inertness, allowing the bars to resist aggressive acids, bases, and solvents commonly encountered in laboratory and industrial environments. The cylindrical design, combined with a precision‑polished surface, minimizes friction and enables rotation speeds of up to 2000 rpm without wobble or vibration, ensuring uniform mixing across a wide range of sample volumes.

Key specifications include a package dimension of 3.7 × 2.64 × 0.28 inches and a lightweight of 1.13 ounces per set, making storage and handling effortless. The product is manufactured by Ckepvo, a trusted name in scientific equipment, and carries the model identifier “Ckepvo” for easy reference. With a best‑sellers rank of #6 in Lab Stirrer Bars, this kit has earned a solid 4.0‑star rating from 15 verified customer reviews, reflecting consistent satisfaction among researchers and technicians.

Usage

These stir bars are engineered for versatility. Whether you are conducting routine chemical synthesis in a university laboratory, performing quality‑control assays in an industrial setting, or maintaining homogeneous conditions in agricultural research, the magnetic stir bars integrate seamlessly with any standard magnetic stirrer or heating plate. Their robust PTFE coating protects against corrosion from acidic or alkaline solutions, making them suitable for tasks such as dissolving reagents, maintaining temperature‑controlled reactions, and supporting fungal culture preparations where sterility and chemical resistance are paramount.

Because the bars are lightweight yet durable, they can be used in multi‑sample workflows, allowing simultaneous stirring of up to eight vessels. This capability reduces overall processing time and improves laboratory efficiency. The white coloration provides visual contrast against typical reaction mixtures, helping users quickly verify bar placement and monitor stirring activity.

FAQ

Can these stir bars be used on heating plates?

Yes, the PTFE coating is designed to withstand temperatures commonly encountered on magnetic heating plates, making them safe for combined stirring and heating applications.

What is the maximum rotation speed?

The bars maintain stable operation up to 2000 rpm, providing efficient mixing for a wide range of sample volumes and viscosities.

Are the stir bars compatible with organic solvents?

Absolutely. PTFE is chemically inert to most organic solvents, so the bars can be used with solvents such as ethanol, acetone, and chloroform without degradation.

How do I clean the stir bars after use?

Rinse the bars with deionized water and, if necessary, a mild detergent. For stubborn residues, a brief soak in a compatible solvent followed by thorough rinsing will restore the PTFE surface.

What warranty does Ckepvo provide?

Ckepvo offers a one‑year limited warranty covering manufacturing defects, backed by responsive technical support to address any performance concerns.
