Elcometer 3580-1 Precision Casting Knife Film Applicator with Adjustable Film Thickness and Leneta Clear Films

The Elcometer 3580-1 Casting Knife Film Applicator is a precision laboratory instrument designed for manually applying uniform, reproducible films of high-viscosity coatings on flat, solid substrates. Constructed from anodised aluminium with a bevelled blade applicator body, it allows for exact control of film thickness, adjustable in fine 10 µm increments across a broad range from 0 to 6000 µm.

Key features include:

• Film Width: 50 mm (2 inches), total applicator width extends by additional 15 mm (0.6 in) due to blade design.
• Micrometric Adjustment: Two integrated screws enable precise thickness control, essential for consistent coatings in bioprocessing and synthetic biology workflows.
• Application: Ideal for high-viscosity fluid coatings, widely used in molecular diagnostics, biotechnology research, and quality control laboratories requiring meticulous coating thickness.
• Material: Durable anodised aluminium ensures longevity and chemical resistance in laboratory environments.
• Included Accessories: Comes with an open box of Leneta clear films (Thickness 175 µm/7 mil, size 194 x 260 mm), which serve as substrates for coating application and allow evaluation of transmitted appearance properties like color, gloss, and transparency. These films also protect drying drawdowns during analysis without obscuring visual assessment, supporting fluorescence analysis and live-cell imaging prep.

This casting knife film applicator is critical for precise coating applications in biomanufacturing processes, gene editing research, and molecular cloning workflows, where reproducible film layers affect assay outcomes and analytical accuracy. Its robust design and fine thickness adjustment make it a versatile tool for researchers in biotechnology and biomedical engineering, ensuring consistent sample preparation across diverse experimental protocols.
