5 Essential Features of Lab Spinning Machines
Here are the 5 essential features of modern lab spinning machines (also known as laboratory spinners or spin coaters), which are critical for thin film deposition in research and development. 1. Precise Speed Control and Range Why it's essential: The rotational speed is the primary variable controlling film thickness and uniformity. A wider range allows for depositing a variety of materials with different viscosities. Low-end speed (e.g., 100 - 500 rpm): Crucial for the "spread cycle," where the solution is evenly distributed over the substrate without excessive甩出 (being thrown off). High-end speed (e.g., 1,000 - 10,000+ rpm): Critical for the "spin cycle," where centrifugal force thins the solution and evaporates the solvent, defining the final film thickness. Higher speeds generally produce thinner, more uniform films. 2. Programmable Acceleration Ramp Why it's essential: How quickly the spinner reaches its target speed is just as important as th...
