The Ossila Bar Coater is an automatic film applicator for producing uniform, large-area thin films at laboratory scale. This version pairs a durable 8 mm toughened glass stage with a printed grid and a set of 16 wire-wound Mayer bars, covering wet film thicknesses from 6 µm to 200 µm.
Bar movement is programmable in 0.01 mm.s -1 steps, with coating speeds between 0.05 and 250 mm.s -1. Holding speed and bar pressure constant helps deliver repeatable film thickness from run to run. The stage travels up to 290 mm (A4) and supports coating widths up to 225 mm, accepting Mayer bars from 220 mm to 255 mm long.
Wet film thickness is set by the gaps between the wire windings, and the relationship between wire diameter and thickness is approximately linear. A quick lock design makes cleaning the stage and drip tray between coatings straightforward, and the system also works with other accessories such as blade coaters, Sheen applicators and Bird applicators.
- Optimizing thin film coatings at laboratory scale with repeatable wet film thicknesses.
- Coating large-area sheet samples up to A4 size.
- Screening film thicknesses from 6 µm to 200 µm using interchangeable Mayer bars.
- Coating solutions across a range of viscosities at programmable speeds.
- Running blade coaters, Sheen applicators or Bird applicators on an automated stage.

Clean the substrate and bar before coating, since dirt or debris can create defects through the whole film. Keep the substrate held firmly in place, and use a spirit level to set the machine level in all directions for uniform coating across the width.
