Pipette tip sorting device 'Elster' for 200 µL pipette tips

thingiverse

This pipette tip sorting device rapidly sorts and transfers 200 µL pipette tips to a storage box, rendering manual sorting obsolete. To function fully, you will need four magnets with a diameter of 3 mm and a height of 2 mm. Designed specifically for 200 µL neutral Sarstedt pipette tips (order no. 70.760.002), this device may also work with other pipette tips, but I cannot guarantee its compatibility. Measure your pipette tips carefully to ensure they will fit. The most critical factor is the width directly beneath the tip head edge, as it affects how smoothly the tips slide along the device's rails. Access a parametric Fusion 360 file (.f3d) at https://a360.co/2JQscTy. Although you'll need Fusion 360 to edit it (available for free), I've incorporated two adjustable parameters: 'pipette tip neck diameter' and 'pipette tip belly diameter'. The first parameter measures the diameter directly beneath the edge of the pipette tip head, while the second measures the diameter 4 mm below the edge. If you have a better idea for making customized files accessible, please share your suggestion. To obtain a customized design, provide me with the exact diameters at the 'neck' and 'belly' of your pipette tips, as well as the brand name and model number of your pipette tips. I will adapt the parameters to suit your needs and send you your personalized design. Good luck!
