3D printable mold for hydrogels

Hydrogel Molding Form


The hydrogel molding form is a custom-designed device developed for the bubbling and curing of hydrogel samples.
Each cavity has a diameter of 20 mm and a height of 3 mm, corresponding to an approximate volume of 940 µL (0.94 mL).
The mold is equipped with precise fittings for syringe connections and septa, allowing clean and controlled gas introduction during the preparation process.

For operation, first fill the cavity with the liquid hydrogel precursor up to the lower edge of the syringe openings.
Then connect a syringe containing argon gas to the angled inlet port so that the gas is gently introduced into the gel.
Insert a second syringe tip into the opposite straight port to allow excess air or argon to escape.
After bubbling, the sample can be cured under UV light directly within the mold.
