Thin Layer Applicator

The thin-layer applicator evenly spreads the sample solution onto a glass plate or aluminum foil substrate using a blade or coating device, forming a film layer with controllable thickness. It is used for sample pretreatment in thin-layer chromatography, preparing the carrier thin layer for the samples to be tested in the laboratory.
Selection
Select manual or automatic models based on sample viscosity, and consider matching the substrate size with the coating width. The coating thickness adjustment range must cover experimental requirements, and stainless steel blades ensure corrosion resistance. Observe coating uniformity and thickness repeatability, and choose models compatible with commonly used thin-layer plate specifications.

The importance of maintaining a constant speed when using a wet film applicator for coating.
When using a wet film applicator, maintaining a constant speed during the scraping process is crucial for coating uniformity. The scraping speed directly affects the wet film thickness, and fluctuations in speed can lead to defects such as streaks and uneven thickness, compromising the repeatability and accuracy of experimental results.
The difference between a wire bar coater and a gap-type wet film applicator.
The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
