The presented device is intended for the incubation of feed samples in enzymatic solutions, simulating digestion by various types of farm animals, provided that an anaerobic environment is not methodologically required. It is intended for smaller quantities of samples (1 to 8 samples). The device can be used especially in laboratories that do not have incubators or other expensive equipment for determining the digestibility of nutrients in different types of feed. The device can be used for a whole range of methods. The advantage is the affordability ensured also by the fact that it uses part of the equipment that is normally used in laboratories.
