{"product_id":"eressvsm","title":"ECS-R Economic Single-Shaft Vacuum Slurry Mixer (1400 rpm, 250 mL), ERESSVSM","description":"\u003cp\u003eAn economic vacuum slurry mixer (often referred to as a compact or benchtop vacuum mixer) is a staple for laboratory-scale R\u0026amp;D and small-scale prototyping, particularly for battery electrode preparation (lithium-ion, sodium-ion, solid-state) and ceramic slurries. When searching for an \"economic\" model, the goal is to balance affordability with the two features critical to slurry quality: effective de-agglomeration (homogenization) and void-free degassing (vacuum).\u003c\/p\u003e\n\u003cp\u003eIn an economic single-shaft setup, the design is simplified to minimize mechanical failure points and reduce manufacturing costs: (1) \u003cstrong\u003eVacuum Cap\/Lid\u003c\/strong\u003e: The mixing shaft passes through a specialized high-speed dynamic seal (usually an oil seal or mechanical face seal) embedded in a heavy-duty lid. This lid clamps securely onto the mixing cup using a silicone or Viton O-ring. (2) \u003cstrong\u003eHigh-Shear Dispersion\u003c\/strong\u003e: The single shaft spins at high velocities (typically 100 to 5,000+ RPM). The sawtooth blade flings the slurry radially outward, creating a vortex that pulls dry powders down into the high-shear zone for rapid wetting and de-agglomeration. (3) \u003cstrong\u003eSimultaneous Degassing\u003c\/strong\u003e: Connectors on the lid attach to a vacuum line. Drawing a vacuum (typically -0.08 to -0.095 MPa) while the vortex is active allows entrapped air bubbles to expand, rise to the surface, and burst instantly, ensuring a highly dense, defect-free slurry for downstream coating.\u003c\/p\u003e\n\u003ctable style=\"height: 844.6px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%;
