Laboratory syringe/injection pump

The laboratory injection pump is a standard instrument used in life science research for long-time uniform microinjection. The rational use of microinjection pumps in experiments can greatly reduce the labor intensity of workers and accurately control the use of various reagents. Introduction of laboratory injection pump: The laboratory injection pump is a kind of injection [...]

Fabrication of PDMS Chip—-PDMS Injection

Fabrication of PDMS Chip----injection After the male-die mold is finished, the next step is to fabricate the PDMS chip in micro-channels by the molding method. The main principle of the molding method is to pour PDMS onto the mold and then solidify it. Then, the separated PDMS substrate bonded to the glass to form a [...]

Su-8 Photoresist Mold Fabrication—-PDMS chip fabrication

The fabrication of the male-die mold Before making die mold, we need to make a mask well in advance. The primary role is to block the specific area in the following photolithography process to transfer the design to a photoresist. The specific process is: first, using CAD software to design the layout of the chip [...]

Nine Key Points For Using Microinjection Syringe Pump In Laboratory

(1) Use a matching power adapter. (2) There is a danger of extrusion between the pushing block and the end block. Do not put your finger between the pushing block and the end block when the injection pump runs. (3) If you push or pull too much when using the syringe, the fluid may overflow, [...]

3 Key parameters affecting the performance of the Spin coater

Rotation Speed The rotation speed and control precision are directly related to the coating's thickness and film uniformity. If the target speed and the motor's actual speed are in considerable error, researchers cannot obtain accurate experimental data for the requirements of precision coating. Construction and cleaning of vacuum adsorption system Vacuum pump pressure calibration to [...]

6 Factors affecting spin coating film thickness

Drip the photoresist onto the surface of the substrate material: The solution or photoresist to be coated can be sprayed or dripped onto the substrate surface using a syringe nozzle. The amount of photoresist usually dripped far exceeds the amount of glue eventually applied to the surface. The rotating speed of the base material can [...]

Spin coating machine working principle

The spin coating apparatus of the homogenizer is widely used in MEMS micro-fabrication, biology, material, and so on. It's used to prepare thin films with thickness less than 10 nm and is also commonly used in about 1-100 micron thick photoresist photolithography process. Many flat substrate materials are used for coating, such as semiconductor silicon [...]

Notes for pipette use

1.Pipette (pipette) should not be dried in the oven. 2. Pipette (pipette) shall not remove solutions that are too hot or too cold. 3. One pipette should be used repeatedly in the same experiment as far as possible. 4. After the pipette raises the liquid level, the liquid adhering to the external wall of the [...]

How to successfully complete PDMS and glass plasma bonding

1.Glass/PDMS plasma bonding Plasma bonding can be used in the fabrication of microfluidic chips. To permanently glue PDMS chips to the glass, the researchers used a plasma cleaner to change the surface properties of the glass and PDMS. The plasma treatment will change the surface chemistry and allow the PDMS to adhere to channels on [...]
