Dipping Chambers for Thin Layer Chromatography

prusaprinters

<p>Tired of jars, breaking glass, and spilled and spoiled staining reagent, we designed a universal dipping chamber for thin-layer chromatography!</p> <p>Three predefined models are provided:<br/> Synthesis Style: medium sized for 10x10 cm plates, with a spout, a lid, and a pedestal to keep it from falling over.<br/> HPTLC: for 20x10 cm plates with a spout, a lid, and a shell to tightly close the lid and store the reagent in the freezer (a sealing ring is recommended!)<br/> Micro: if you like using really small plate and need really just very little reagent; with a pedestal and a lid.</p> <p>If you want to make your own custom chamber, use the "dipping_chamber_parameters.scad" to set the dimensions and add or remove options. Presets for the three provided chambers are provided in the "dipping_chamber_parameters_Synthesis Style/HPTLC/Micro.scad" file.<br/> After adjusting the settings in the parameters-file, use "dipping_chamber.scad" to prepare an stl for the dipping chamber, "dipping_chamber_lid.scad" for a lid, and "dipping_chamber_shell.scad" for a shell to hold the lid in place. Please take a moment before printing to check if the models make sense, as OpenSCAD does not prevent you from entering silly parameters.<br/> Please take a moment after printing to check if the chamber is tight, because printing PP is not easy.</p> <p>Interested in a more chemical perspective?
