The Amazing ramé-hart Prebuilt Circular Spinneret Array Kit

Designed for the demanding pace of R&D, the versatile Prebuilt Circular Spinneret Array Kit (p/n 100-10-PCAA) is an essential tool in our spinneret line, engineered to dramatically accelerate your electrospinning and electrospraying production and scale-up. The Array Kit is a powerful dispensing head for simultaneously and uniformly dispensing up to 17 output flows, each with a Luer lock fitting.

The circular array offers a crucial advantage over a single needle: rapid and uniform coverage of a larger target volume. Simultaneous multi-stream dispensing provides an immediate, significant increase in throughput and efficiency, which is vital for scaling research to manufacturing readiness.

The ramé-hart Prebuilt Circular Spinneret Array provides a variety of benefits:

• Rapid Prototyping and Screening: The array enables simultaneous, high-speed testing of different materials, solution concentrations, or process parameters. You can rapidly determine the optimal formulation or conditions, shrinking months of work into weeks.
• Advanced Spray and Spin Pattern Design: Easily change out the needles or tips and plug unused ports to test a vast variety of spinning patterns for both electrospraying and electrospinning applications. Quickly map out optimal coverage patterns.
• Variable Tip Diameter Testing: The simple Luer lock fittings permit fast needle swaps to test a wide range of gauge sizes. This allows for quick optimization of flow rates and droplet formations for your specific application.
• Superior Coating and Sample Uniformity: Utilizing up to 17 precisely positioned needle tips ensures vastly improved overall uniformity across your sample or substrate. For niche applications, you can even achieve random, non-uniform coatings—by selecting a mix of different needle sizes and port positions —for unique, engineered results.
• Parallel Fluid Administration: In fluidic applications, the array becomes a powerful tool for uniformly dispensing the fluids through many output needles simultaneously ensuring consistency and optimal results.

ramé-hart for years has developed precision spinnerets, arrays, and custom-built solutions that continue to push the boundaries of innovation. These products are used in a variety of fields:

• Nonwoven Material Research
• Biomedical and Healthcare
• Filtration and Environmental Applications
• Battery and Fuel Cell Design
• Material Science and Chemical Engineering
• Aerospace and Automotive Manufacturing
• Advanced Fabrics including Smart Textiles and Wearable Electronis
• Food Processing

In addition to our standard Prebuilt Circular Spinneret Array Kit (p/n 100-10-PCAA), we also have three new prebuilt circular array products. Visit this page on our custom spinnerets website for more product information on all of our prebuilt linear and circular array products which are in stock and ready to ship.

Material researchers rely on the ramé-hart spinneret arrays to accelerate their work and material development. Should you need an array model outside of our standard prebuilt offerings, we're ready to help. Share your specifications with us; our custom fabrication expertise means we can build a spinneret array tailored to your precise needs.
