Droplet transfer mechanism – femto-SpotterTM
With advanced technology, innovative dispensers have been created. We will provide new liquid control technology by greatly improving the shortcomings of conventional dispensers.
To control the volume of fluid precisely is quite difficult but crucial for micro-machining.
femto-SpotterTM is an ultra-micro droplet transfer dispenser which is able to solve your problems at the manufacturing site.
This is a promising technology for manufacturing in future. Inquiries pour in from all over the world!

Overview
- More smaller, more precise, more reliable. A state-of-the-art dispensing system is capable of dispensing ultra-small droplet quantities to meet the demands in the world of industry.
- femto-SpotterTM can transfer and/or apply a tiny amount of liquid to the exact position.
- The amount of liquid dispensed with femto-SpotterTM is miniscule, as small as fL (femto-liter). Moreover, it can handle high-viscosity liquids, thus solving the problems of conventional dispensers.
- femto-SpotterTM is versatile system. It can be used stand-alone or integrated into a system.
Features
| Ultrafine droplet | A dispenser that can apply liquid in ultrafine amounts (fL, pL, nL) that was previously impossible. Ranging femto-, pico-, nano-, micro-liter droplet can be transferred to substrate with changing some parameters. |
| High-viscosity liquids | Applicable to various liquids with viscosities ranging from low to high (up to 200,000mPa·s). |
| Accuracy | Precise application to a specific location (position accuracy: several µm). |
| Filler compatibility | Liquids containing fillers are available. |
| No clogging | Pushing a needle prevents from clogging |
| No dead volume | Liquids can be perfectly used down to the last drop. |
| Compact in size | The main body is compact for embedding on other system. |
| Customize | We can offer to customize the dispenser so that it fits to your system. |
| System integrate | Desktop system, fully automated system are available. |

Mechanism Overview
Mechanism
- Needle: a needle that transfers liquid droplets
- Reservoir: a cylinder that holds the coating liquid
- Coating liquid: liquid to be applied by the needle is held in the reservoir
- Coating object: transfers the tiny liquid droplets adhered to the tip of the needle
Operation
- The needle descends inside the reservoir.
- The needle protrudes from the hole in the reservoir to the outside.
- Tiny droplets of liquid adhering to the tip of the needle are transferred to the object surface.
- The needle rises and returns to the reservoir, and moves on to the next coating.
