100mm Laboratory Film Applicator Micrometer Adjustable Doctor Blade Coater

Product Overview

This lab-scale film applicator delivers precise, reproducible wet film deposition across flat substrates, providing an indispensable tool for advanced surface coating evaluation. Engineered with dual high-precision micrometer heads, the equipment allows researchers to fine-tune the doctor blade clearance with micro-meter resolution, ensuring uniform slurry distribution for sensitive analytical and experimental workflows.

Primarily utilized in battery research and development, this system excels at casting cathode and anode electrode slurries, solid-state electrolyte membranes, ceramic tapes, crystal films, and specialized functional nanocoatings. Its versatile design accommodates diverse fluid viscosities, enabling seamless transition between aqueous suspensions, organic pastes, and complex polymeric formulations across academic, industrial, and pilot-line laboratory environments.

Constructed from heavy-duty, corrosion-resistant alloys, the equipment guarantees exceptional dimensional stability and long-term durability under demanding chemical and mechanical operational conditions. Its geometrically optimized profile and compact footprint ensure effortless handling, rapid setup, and consistent, high-accuracy film casting during repetitive testing protocols.

Key Features

• Dual Precision Micrometer Gap Control: Integrated twin micrometer heads enable independent yet synchronized vertical adjustment of the coating blade, allowing operators to set the precise gap clearance from 0 to 3500 µm with an accurate 10 µm scale resolution.
• Corrosion-Resistant Structural Alloys: Manufactured from premium-grade stainless and treated metal components, the applicator resists aggressive chemical solvents, acidic slurries, and organic additives to maintain structural integrity and extend service life.
• Broad Wet Thickness Clearance Range: Offering an expansive adjustment range up to 3500 µm, this unit accommodates extremely thin nanometer-scale film preparation as well as thick viscous slurry coatings within a single versatile device.
• Geometrically Optimized Fluid Channeling: Designed with a refined structural geometry, the doctor blade frame prevents slurry leakage while facilitating smooth, friction-free movement across glass, foil, or polymer substrates.
• Simplified Zero-Point Calibration Protocol: Features an intuitive dual-screw locking mechanism that allows operators to rapidly recalibrate zero-point alignment against a reference flat plate, ensuring consistent baseline precision before every coating run.
• Compact and Ergonomic Form Factor: The low-profile, lightweight engineering permits effortless handheld operation or automated doctor-blade integration, making it ideal for cleanroom benches, gloveboxes, and compact laboratory hoods.
• High-Uniformity Edge-to-Edge Metering: The precision-ground blade edge provides uniform shear force along the entire 100mm coating width, eliminating edge pooling and film thickness variations across the sample surface.
