Burette / Thermometer Holder for test tube clamp

thingiverse

This device is engineered to securely hold small diameter burettes and thermometers using test tube clamps on ring stands. Before this design was implemented, we relied on string to tie the thermometer to the test tube clamp, allowing them to hang freely. However, regular burette clamps were not capable of gripping small enough diameters to hold the thermometers in place, and attempting to do so would often cause the tiny burettes to snap. To use this device effectively, you will need to print two identical items that work together. The notch is intentionally designed not to allow the two parts to fully close, as this would allow the thermometer or burette to slip through. Instead, a small amount of friction is necessary to hold it in place. Applying a bit of liquid tape has also proven beneficial, as it creates a rubbery surface that enhances grip.
