Microfluidic Circulation System (Liquid)

Other brands of liquid sample tables commonly used in the market, due to the restriction of their own liquid pool chip design scheme, can only push the large flow of liquid through the sample table and the peripheral area of the chip through the huge pressure generated by the liquid pump, which has the security risk of a large amount of liquid leakage. The liquid enters the nanopore channel in the middle of the chip mainly by diffusion effect, and there is no real flow rate control in the chip observation window. Different from this, our company uses microfluidic technology, through the piezoelectric microcontrol system for fluid differential control, to achieve micro upgrade of micro fluid transport, each liquid push process, the liquid microfluidic circulation system and sample table in the amount of redundant liquid only slightly up, effectively ensure the safety of electron microscopy. Compared with O-ring sealing, the polymer membrane surface contact sealing technology increases the sealing contact area and effectively reduces the leakage risk. On the touch screen control panel, there are two optional modes: set flow rate and set flow rate, which can quickly and easily change the liquid flow rate, control the liquid layer thickness and other experimental conditions. From confirmation of the change condition to stabilization, the time can be controlled within 10 seconds. Static closed working mode can also be selected on the touch screen control panel. The material of the fluid pipe is PTFE or PEEK non-metallic pipe, which is inert to most fluids to avoid contamination of the fluid sample and ensure that no other foreign matter is introduced into the experimental environment.

Eletron Microscope Flange

When replacing the fluid pool chip with a static pool chip, you do not need to remove the flange, but only need to replace the flow channel hole plug. The liquid thermoelectric in situ sample station can be connected with the mainstream electrochemical workstation through the flange to perform electrochemical impedance spectroscopy, cyclic voltammetry, chronocurrent method, cyclic polarization, charge-discharge curve analysis.

SEM High Vacuum Leak Checking Station

It is composed of a visual high vacuum leak detection chamber and a high vacuum pre-pumping system, which simulates the internal environment of the electron microscope, and can quickly check the tightness of the sample table and MEMS chip to ensure the safety of the electron microscope. Limit vacuum ≤8×10-7 hPa, leak detection operation vacuum ≤5.4×10-6 hPa.

Cryo Stage Workstation

The rapid freezing sample preparation technology fixes the sample in the glassy ice layer to avoid the destruction of the sample structure by water or solvent crystallization, and can maintain the microstructure of organic molecular self-assembly and chemical reaction intermediates in the liquid phase to avoid the structural changes caused by sample drying. The tank is filled with liquid nitrogen, and the front end of the sample rod is first inserted into the cold support station to cool the sample rod tip components. The innovative structural design makes the sample loading and transfer operation very convenient. After the sample is loaded, the integrated temperature cover at the front of the sample rod can be closed to prevent atmospheric water condensation during the sample transfer to the TEM.

Cleaning Instrument for Sample Holders

Fluid rod cleaning instrument is a flow pipe cleaning equipment with automatic cleaning system, which is mainly composed of cleaning system, rehydration system, lifting platform, fluid rod card slot, display screen and other parts. The cleaning instrument can clean the flow channel tube in the fluid sample rod through two procedures of liquid flushing and gas drying, so as to avoid the contamination of liquid samples and affect the experimental results, and ensure the normal conduct of scientific experiments. The touch screen is simple and easy to operate, while the automatic program setting makes the cleaning of the fluid pipe more efficient and convenient.

light Source Station

High uniformity integrated laser light source can integrate different wavelengths of laser, can solve the research needs of photocatalysis and other fine development direction, can meet the higher performance requirements in energy, spectrum, irradiation stability, etc., widely used in the photolytic water hydrogen production, photodegradation of pollutants, all kinds of simulated visible light acceleration experiments, all kinds of simulated solar ultraviolet band acceleration experiments and other research fields. Because the energy is stable and uniform, it can also be applied to photoelectrochemistry, optical power measurement, quantum efficiency measurement and other scenarios.

Thermal Controller

The temperature controller customized for the electron microscope customer is adapted to the in-situ micro-zone heating chip of our company, and the micro-zone of the in-situ heating chip is heated and controlled by electric heating. The heating chip and the high-frequency feedback temperature controller are transmitted through the electrical connection unit for high-frequency temperature signals. The high precision and high frequency output, reception, feedback and adjustment of temperature signal are realized through the high precision temperature control program, so as to carry out the process of program heating and cooling.
