![]() ![]() ![]() These panels can be measured for colour, reflectance and gloss on the Optical Coatings System produced by Labman. Drawbar definition, a heavy bar, often made of steel, attached to the rear of a tractor and used as a hitch for pulling machinery, as a plow or mower. The panel is pushed into the stacker and the process is repeated. A drawdown bar is moved across the panel creating a thin film of sample. Made out of stainless steel, these rods apply accurately coatings of. We can not guarantee that you will drawdown the theoretical wet film thickness. A mould rack can replace the slide rack, in which case sample is dispensed without a die into the desired moulds.įor panel drawdown, a panel is placed on the vacuum bed where the syringe dispenses a measured amount of sample. Impression beds hold the substrate material firmly in place to ensure accurate drawdown. BYK-Gardner on the bar applicator is 3 mils. The thin films created can be measured directly for thickness and resistivity by another system designed by Labman. The system dispenses a measured amount of sample and draws downs using the die onto 20 glass slides secured in a universal slide rack. The process starts with the system picking a syringe, reading the barcode and de-capping it.įor slide drawdown, a die is placed on the syringe tip. The system dispenses sample from a syringe onto the desired surface or mould, consisting of an XYZ gantry and stacker axis to receive drawn down panels. ![]()
