Equipment
Our lab counts with all the necessary equipment for polymer processing and analysis, as well as for cell culture studies with several different type of mammalian cells.

Thermogravimetric Analysis (TGA)
The TG 209 F3 Tarsus from Netzch is used to obtain knowledge about the thermal stability of polymers and their composition.
Responsible persons: Pavel Milkin - Muzaffar Maksumov
Differential Scanning Calorimeter (DSC)
The Mettler Toledo DSC device is used to determine the thermal properties of the processed and synthesized polymers. It measures the enthalpy changes of the samples based on their physical and chemical properties as function of temperature.

3D printers
3D Discovery Regen-Hu
3D Discovery printer inside of the biosafety cabinet (RegenHU, Switzerland). It can be used for printing hydrogels, thermopolymers, and melt-electrowrite polymers. It counts with multiple printheads.
Responsible persons: Gissela Constante - Zhander Soreño

Melt-electrowriting - 3D Printer of Thermoplastic polymers
Dispensing 3D printer for printing of thermoplastics with four heated pneumatic dispensers. Maximum temperature is 350 ° C that allows printing of most commercial and synthetic polymers. Commonly polymers are printed on heated stage (max T = 80°C). Pressure is electronically controlled in the range between 0 and 10 Bar. Printer is equipped with high-voltage power supply (30kV), which allows melt electrospinning writing.
Responsible persons: Gissela Constante - Waseem Kitana
