Dispersing Disc QWORK Stainless Steel Impeller 8×300mm Rod 50mm

Description

Product Overview

The QWORK Dispersing Disc Impeller is engineered from premium 304 stainless steel, a material renowned for its corrosion resistance, high tensile strength, and suitability for humid laboratory environments. Each unit incorporates an 8 mm stir bar, a 50 mm disc, and a 300 mm rod, delivering a balanced combination of size and performance that fits a wide range of overhead stirrers and laboratory mixers. The disc design induces a powerful radial flow, promoting uniform dispersion across both upper and lower layers of the medium, which is essential for achieving consistent particle size distribution in coatings, pigments, inks, adhesives, and pharmaceutical formulations. The impeller’s dimensions—8 mm stir bar diameter, 50 mm disc diameter, and 300 mm rod length—provide a versatile footprint that can be adapted to various vessel sizes, from small beakers to larger reactors, without sacrificing mixing efficiency.

Manufactured with precision machining, the impeller features a smooth, polished surface that minimizes shear stress on delicate compounds while still delivering the high‑speed agitation required for demanding processes. The flange‑nut fastening system offers a large clamping area, ensuring a secure connection that reduces vibration and prevents accidental disengagement during operation. This design also simplifies maintenance; the disc and rod can be quickly removed, inspected, and replaced without the need for specialized tools, thereby reducing downtime and supporting continuous production workflows.

Usage

Designed for laboratory and industrial applications, the QWORK dispersing disc excels in environments where precise, repeatable mixing is critical. In research labs, it supports formulation development for paints, coatings, and inks, allowing scientists to evaluate rheological properties and pigment dispersion with confidence. In pharmaceutical settings, the impeller facilitates the homogenization of active pharmaceutical ingredients (APIs) with excipients, ensuring uniform dosage and stability. The robust stainless‑steel construction also makes it suitable for use in adhesive manufacturing, where aggressive mixing of resin systems is required.

Because the impeller can operate at medium to high speeds, it adapts to a range of viscosity levels—from low‑viscosity solvents to high‑viscosity pastes—making it a universal accessory for mechanical equipment such as dispersers, pulverizers, and high‑shear mixers. Its compatibility with standard overhead stirrer shafts means that users can integrate the impeller into existing setups without extensive re‑engineering, saving both time and capital investment.

Safety is a paramount consideration; the flange‑nut system provides a stable, locked connection that prevents accidental detachment, while the stainless‑steel material resists rust and contamination, maintaining the purity of sensitive chemical batches. The impeller’s compact size also allows for easy storage and handling, fitting comfortably within standard laboratory cabinets and safety enclosures.
