The gas level measuring device with a capillary made by 3-D printing
Halva, Ondřej ; Búran, Martin (referee) ; Adámek, Martin (advisor)
This thesis is concerned with the experimental design, manufacture, and testing of a 3D printed prototype of a capillary. The aim is to introduce the reader to the issue of 3D printing related to the manufacture of capillaries and focus on chemiresist sensors. Furthermore, the features of microcontroller Atmel Atmega2560 and its applications in sensory technology will be described. In the second part of the thesis, the capillary for sample pre-processing with an output to a gas measuring device with an electrochemical sensor is designed and produced. For the control of the device, the Atmel Atmega 2560 microcontroller is to be used and the device must enable data transfer to PC. The possible applications of the capillary are to be evaluated.

Preparation and testing of capillary packed column sephadex G-10
Tolasz, Jakub ; Coufal, Pavel (advisor) ; Sobotníková, Jana (referee)
Sephadex is a common sorbent in biochemistry for separation of molecules of a wide range of molecular masses. Sephadex is also used for purification or desalination of isolated proteins. Up to now, the gel chromatography has been performed in wide separation columns. Therefore, the isolation techniques for proteins had to be very effective to isolate enough proteins as a sufficient amount of the sample. The preparation and application of a capillary separation column packed with sephadex could decrease the needed sample amount and enable work with hardly isolable proteins obtained only in small quantities. In this bachelor project, the capillary column was packed with sephadex using the slurry packing procedure. The principle of monolithic columns was used to create a gel in the column. The column was packed in organic solvent firs, and then hydrated when flushing with water to generate the gel.
