Slot-Die Head, Shims & Meniscus Guides
Slot-Die Heads
Slot-die coating heads provide channels for the even distribution of solution across the width of coating. The shape of the lips at the exit to the head can help to stabilize the coating bead and provide improved coating quality. Combined with the slot-die shims, the slot die head, can provide even coating across a wide range of different coating rates and solution viscosities.

Slot-Die Shims
Slot-die coating heads require the use of shims to define the coating width. Shims can also be used as spacers to separate the sections of the heads to change the internal pressure for higher flow rates or more viscous solutions. Ossila sell slot-die shims in packs of 5 with predefined coating widths of 25 mm and 50 mm. Custom shim widths are available upon request. A full list of in stock shim designs can be found here.
Meniscus guides are available for 50 mm and 25 mm wide coating widths, sets are available with 0.5 mm, 1 mm, and 1.5 mm protrusions to begin to optimize your coating procedure.
