The Ossila Slot Die Coater is a complete benchtop system for depositing uniform thin films over a coating area of up to 150 cm². It combines a high-precision syringe pump, a heated stage and an interchangeable stainless steel slot die head, giving researchers a practical route from small-scale experiments towards scalable coating.
Stage speed can be set anywhere from 50 μm.s -1 to 75 mm.s -1, and the flow rate spans 0.5–624 μl.s -1 with a 5 ml syringe. Micro-step control delivers accurate solution flow with defined start and stop points. The hotplate reaches 140 °C, helping wetting and film drying, and a temperature offset can compensate for substrate-to-stage differences under high air flow. Gap height is tuned with two-point levelling using precision micrometer heads.
Interchangeable stainless steel shims and meniscus guides set channel thickness and stabilise the meniscus. A standard head handles 0 – 1000 cPs, while the high viscosity model covers 1000 – 10,000 cPs. The head is offered in 50 mm and 100 mm widths, and intuitive software supports multi-step programming.
- Coating uniform thin films over large substrate areas in research laboratories.
- Optimising film thickness and defect-free coatings by varying stage speed, flow rate and gap height.
- Depositing high viscosity inks and solutions from 1000 to 10,000 cPs with the high viscosity head.
- Studying the effect of stage temperature on wetting and film drying.
- Scaling up solution-processed films from lab-scale experiments.
