Freezedryer-lyophilisation frame for 2R vials, Christ Epsilon
thingiverse
This is a smaller frame and tray to hold 2R vials, which fits into a Christ Esilon 2-10D LSCplus freezedryer (lyophilisation) device.We needed this part in order to transport vials to the freezedryer enclosed in a plastic aseptic bag. The original stainless steel parts fitted into the machine flush, without any space on the sides. To allow space for the bags, we needed to reduce the width of the frame and underlying tray.The original stainless still inner-frame was 300x300mm. This smaller printed version is 10mm shorter (290x290mm). When constructed, the printed outer frame is 300x300mm.This print requires a large buildplate of at least 300mm x 300mm. Because the inner frame must undergo the cold temperatures and vacuum of the freezedrying process, we would not recommend using glue, and instead recommend printing the inner frame as one part, in a robust material (e.g. PETG, ABS, HIPS), at 100% infill.Instructions:print the test_corner.stl in a robust material, and check that the material and part is not damaged during the freezedrying process.print the inner_frame.stl as one piece. As an alternative, you could try inner_frame_with_structure.stl, which requires less material.buy a 2mm thick 30x30cm clear perspex plate to act as a base. You can find these online.print outer_frame_sides.stl twice, and outer_frame_backside.stl once. The outer tray containing these parts is removed before freezedrying, but I would still recommend a robust material such as PETG.glue the outer frame sides and backside onto the perspex plate.sand down the side of the perspex to make a ramp, so that the vials slide out easily onto the freezedryer shelf without tipping over.Credits:Mark Teese & Lars Janoschek : 3D design, printing, & testing
