Researchers successfully 3D printed a new thin-layer chromatographic plate with high cost performance

Abstract: Morlock and fichou also 3D printed a plate with 40 channels. The printing time was less than 2 minutes, and the cost was 0.4 US dollars

thin layer chromatography is a chromatographic separation technology for the separation, identification and quantification of mixed samples. It will separate the mixture on a thin layer plate coated with absorbent materials. Generally, the surface material is composed of silica gel, and the carrier plate is glass plate or plastic sheet

German Li (6) has strong working reliability, durability and adaptability to low temperature. Gertrud Morlock, a researcher at the University of bisch, successfully manufactured a thin-layer chromatographic plate with a thin silicone layer for 3D printing by using prusa I3 open source 3D printer

prusa I3 can be customized according to various applications, because it is sold in the form of kits. Morlock and her colleague Dimitri fichou replaced the extruder in the original kit with a component that can 3D print a thin silicone layer. According to Morlock, this customized prusa I3 3D printer is specially designed by fichou for thin-layer chromatography

thin layer chromatography is a kind of chromatographic separation technology for separating, identifying and quantifying mixed samples. It is hard and tough: large elastic modulus technology. Generally, the surface material is composed of silica gel, and the carrier plate is glass plate or plastic sheet

the position sensor can ensure that the extruder or syringe containing silica gel will always keep a certain distance from the glass plate, thus allowing a flat 3D printing surface to be created on the glass plate. "The layer printing process is very fast. Print a 10 × 10cm format, 0.2mm thick layer takes less than 5 minutes. In addition, the values in the list are also different, which is affordable. The operating cost of producing such a board is less than 0.25 euros, and the cost of modified hardware is 630 euros, "the researchers explained

morlock and fichou also 3D printed a board with 40 channels. The printing time was less than 2 minutes and the cost was $0.40. "We open source released all of the hardware and software, bringing large production modifications to the enterprise to encourage everyone to use and improve, and encourage everyone to contribute to this technology," the researchers said
