A tissue cassette assembly includes a housing having a recess formed therein, and a compressible reservoir disposed partially or wholly inside of, or otherwise attached in fluid communication with, the housing recess, the compressible reservoir containing a tissue embedding material. The tissue cassette further includes a port disposed in the housing, the port in fluid communication with the compressible reservoir at one end and terminating in a sample cavity at another end. During operation, the compressible reservoir is compressed or squeezed to release the tissue embedding material into the sample cavity containing the biological sample.

The invention provides a low-temperature tissue embedding temperature control system, and belongs to the technical field of biospecimen low-temperature tissue embedding. The low-temperature tissue embedding temperature control system is high in working efficiency, and good in use effect. The system comprises a heating and refrigerating semiconductor element and a control circuit; a control signal output end port of the control circuit is connected to a control signal input port of the heating and refrigerating semiconductor element; a detection signal input port of the control circuit is connected with a detection signal output port of a temperature sensor for detecting the temperature of the heating and refrigerating semiconductor element; the control circuit comprises a CPU, a power conversion part, a system control part, a storage, a system feedback part, a display part, a Bluetooth part and a heat dissipating control part; the control signal output port of the CPU is correspondingly connected with the control signal input port of the system control part and the control signal input port of the heat dissipating control part.

The invention provides a dewaxing device of a tissue embedding machine; the dewaxing device is capable of continuously discharging wax, and comprises a main dewaxing cylinder and an auxiliary dewaxing cylinder, wherein the auxiliary dewaxing cylinder is provided with a first heating device; the bottom of the main dewaxing cylinder is provided with a wax outlet pipe; a wax conveying pipe is arranged between the main dewaxing cylinder and the auxiliary dewaxing cylinder; the auxiliary dewaxing cylinder is provided with a wax feeding hole and an air inlet; the auxiliary dewaxing cylinder is hermetically arranged; a second heating device is arranged at the pipe orifice of the wax outlet pipe. The dewaxing device of the tissue embedding machine has the beneficial effects that the auxiliary dewaxing cylinder can be used for providing standby wax for the main dewaxing cylinder in time, so that the liquid paraffin wax is continuously supplied without waiting; the heating device arranged at the pipe orifice of the wax outlet pipe can be used for separately heating paraffin wax at the pipe orifice, so that the paraffin wax is prevented from being cooled and hardened, the wax is smooth in flow, and wax blockage is avoided; the wax conveying pipe is controlled to convey the liquid paraffin wax by enabling the air inlet to be filled with high-pressure air, and a control valve is not arranged in the wax conveying pipe, so that wax leakage is avoided.
