Split type injection pumpIt is a precision fluid transport device that separates the controller from the pump body, widely used in laboratory research, biopharmaceuticals, chemical synthesis, and medical equipment fields. The core design advantage lies in its modular structure, where the controller acts as the "brain" responsible for setting and adjusting injection parameters such as flow rate, volume, injection time, etc., while the pump body (execution unit) is responsible for storing and delivering liquids. This separation design allows users to choose different specifications of syringes (0.5 μ L-100mL) according to their needs, to adapt to different application scenarios and work requirements.
Split type injection pumpThe working principle of the syringe is based on the stepper motor driving the screw to rotate, converting the rotational motion into linear motion, and pushing the syringe piston for high-precision liquid transfer. Its technical parameters include multi-channel control (independent operation of 1-8 channels), ultra wide linear velocity range (0.078 μ m/min-133mm/min), high control accuracy (≤± 0.5%), and large linear thrust (>200N). The device supports multiple working modes such as timed, quantitative, and gradient injection, and is equipped with practical functions such as power-off memory, flow calibration, and fast forward/rewind to ensure ease of operation and data reliability.
Split type injection pumpIts main application scope and specific scenarios:
1、 Biomedical and Life Sciences
Drug development and experimentation
Animal experiments: precise control of drug infusion rate (such as constant rate administration, dose gradient experiments).
Cell culture: Continuous or pulsed addition of culture medium, antibodies, or inhibitors to simulate physiological environment.
Microinjection: Injecting RNA, protein, or fluorescent markers into cells during microscopic operations.
Medical treatment
Chemotherapy/analgesia: used for precise drug delivery in clinical or laboratory settings (such as in the treatment of mouse tumor models).
Vaccine development: Inject antigens or adjuvants into experimental animals at a constant rate to observe immune responses.
laboratory research
Electrophysiological experiment: Inject electrolyte solution into cells or tissues to maintain activity.
PCR/sequencing: precise addition of reagents (such as enzymes, dNTPs) to avoid manual errors.
2、 Chemistry and Materials Science
Chemical reaction control
Titration experiment: Add reaction reagents (such as acid, base, catalyst) as needed, and precisely control the reaction rate.
Nanomaterial synthesis: Constant rate infusion of precursor solution to regulate particle size and distribution (such as quantum dots, liposomes).
Supporting analytical instruments
HPLC/GC injection: replaces manual injection to achieve automated and high-precision sample injection.
Spectrometer testing: Continuous flow detection of samples to reduce human interference.
3、 Industrial and Food Testing
Fluid filling and distribution
Micro filling: Accurately distribute micro upgraded liquids (such as reagents, fragrances, additives) for small batch production or quality control.
Online sampling: Regularly and quantitatively extract liquid samples (such as beverages and chemical products) from the assembly line for real-time monitoring.
process optimization
Reaction condition screening: Explore the optimal reaction parameters (such as temperature, concentration, flow rate) through gradient infusion.
Emulsification and mixing: control the injection rate of oil-water phase to prepare stable lotion or gel materials.
4、 Environment and Agriculture
environmental monitoring
Soil/water remediation: Inject remediation agents (such as microbial agents and chelating agents) at a constant rate to control the pollution control process.
Sampling analysis: Automated collection of water samples or soil leachate for heavy metal and pollutant detection.
agricultural research
Plant irrigation: Simulating natural rainfall or nutrient transport, studying the response of crops to different irrigation rates.
Pesticide/fertilizer testing: Accurately control the dosage of pesticides, evaluate their effectiveness and environmental impact.
5、 Special scenario applications
Aseptic/closed environment
Cell culture chamber: The split pump head can be placed in a sterile operating table or biosafety cabinet to avoid contamination.
Isolation experiment: Through a split design, the host can be placed outside the clean area, with only the pump head in contact with the experimental environment.
High/low temperature environment
Extreme d condition experiment: The pump head can be placed in a temperature control box or heating/cooling device to meet the requirements of high temperature sterilization or low temperature reaction.
Dangerous liquid handling
Corrosive/volatile liquids: Pump heads made of corrosion-resistant materials such as PTFE and Hastelloy are used for safe infusion of strong acids, alkalis, or organic solvents.
