Precision Slot Die Coating for All Laboratories
Scale up your thin film processing with our compact and affordable slot die coater
Part of the Institute of Physics award-winning solar cell prototyping platform, the Ossila Slot Die Coater is much smaller than other models on the market but just as precise. Despite its reduced size, it also includes an integrated syringe pump for synchronised start and end times.
Our slot die coater is fully operable via the digital controls on the unit itself. This allows you to easily programme multi-step processes, where different parts of the system can each be controlled independently. Up to 20 of these programmes can be saved, each of which can contain up to 50 steps, for easy repeat experiments. You have control over temperature, substrate speed and alignment, solution flow rate, channel thickness, head height, and more.
This product is covered by our two-year warranty and is eligible for free worldwide shipping. Designed to be used by both beginners and experts, order your slot die coater today to scale up your thin film processing. A range of slot die coater accessories including heads, shims and tubing can also be purchased separately.

3-point levelling system
Easy to Use
User friendly design
Low Operating Costs
Low energy consumption
Designed with lab space in mind, our compact desktop design allows the Ossila Slot Die Coater to be placed on standard laboratory benches, fume hoods, and even within gloveboxes.
Easy Set Up
Ready for immediate use upon being plugged into a power socket. With no need for compressed gasses or vacuum lines, the Ossila Slot Die Coater can easily be moved between different labs and environments.
By using a simple coat-hanger design for the distribution of solution, the flow rate across the head width is made uniform. This results in highly even coatings across the width for a wide range of viscosities. The stainless-steel slot die head allows for compatibility with the widest range of materials possible.
Variable Channel Thickness
Interchangeable stainless-steel shims allow the user to change the thickness of the slot die channel, increasing the range of different solutions that can be processed with a single slot die head. By inserting multiple shims, the channel thickness can be increased in intervals of 100μm.
Uniform Flow Rates and thicknesses
For accurate and repeatable film thicknesses, the Ossila Slot Die Coater has an in-built syringe pump. This gives precise control over the amount of solution entering the system. The in-built software makes programming synchronised starting times easy.
A built-in hotplate on the stage allows the temperature of the substrate to be controlled. This can improve the wetting of solutions by reducing the surface tension and allows the drying rates to be varied. For environments with high air flow, a temperature offset can be set to correct for differences between the substrate and hotplate temperature.
Wide Range of Substrate Speeds
Our motorised stage allows for smooth, continuous movement. With the motor capable of moving at speeds from as low as 100 μm.s-1 to as high as 50 mm.s-1, the system has a wide processing window for control of the meniscus.
By using a 3-point levelling system along with high precision micrometer gauges it is possible to precisely align the stage relative to the head.
Head Height Control
Two micrometers on top of the head carriage allow for the adjustment of the slot die head relative to the stage. By varying the gap height, the stability of the meniscus can be improved, and the minimum wet film thickness can be changed.
The Ossila Slot Die Coater is completely controlled by in-built software. Complex multi-step processes can be programmed with fine control over solution dispense rates, dispense volumes, dispense times, and stage speed.
The intuitive, easy-to-use in-built software used in Ossila's other products has been incorporated into our slot die coater. A full-colour LCD provides a clear bright view of the screen, and the in-built software allows for the programming of complex multi-step processes where the different parts of the system can be controlled independently. As all elements are contained within the system, there is no need for any external computer controls - further saving money and space within the labs.
The slot die system is capable of saving 20 different programmes containing up to 50 steps each. These steps allow the user to choose various solution dispense rates, dispense volumes, dispense times, stage speed, and distance moved. Combined with the simple-to-use control panel and user interface, programming of the system can be done quickly.
Our slot die coating system comes with various safety features to ensure user protection. Maximum force settings can be applied for the syringe driver to reduce the chance of damage to delicate glass syringes. In addition, safety interlocks stop the system from crashing at the end of the travel (for both the syringe pump and motorised stage).
