Air Displacement Principle.
Explain the Principle of Air Displacement and Positive Displacement PI
Air displacement pipetting, also known as blowout pipetting or reverse pipetting, is a technique used in laboratories to dispense liquids with high accuracy and precision. The principle behind air pipetting is that a positive air pressure is used to dispense a liquid from a pipette tip.

To perform air displacement pipetting, a pipette with a disposable tip is used. The tip is attached to the end of the pipette, and the liquid to be dispensed is drawn up into the tip using the pipette's plunger. Once the desired volume of liquid is in the tip, the pipette is held in a vertical position and the plunger is depressed slightly to create a positive air pressure in the pipette.

The positive air pressure forces the liquid out of the tip in a controlled manner, allowing the user to dispense precise volumes of liquid. The tip is then removed from the liquid, and any remaining liquid in the tip is expelled using the same positive air pressure.

Air displacement pipetting is particularly useful when dispensing viscous or foamy liquids that are difficult to dispense using traditional pipetting techniques. It is also useful when working with small volumes of liquid, as it allows for precise and accurate dispensing.

However, it is important to note that air displacement pipetting can create aerosols and droplets, which can pose a safety hazard when working with hazardous materials. Proper safety precautions, including the use of personal protective equipment and proper ventilation, should always be taken when performing air pipetting in the laboratory.

Air Displacement Pipettes FAQs

What is air displacement pipette used for?
Specific quantities of liquids are moved from one location to another using air displacement pipettes. These are mostly utilized in analytical and microbiological studies, cell biology, DNA analysis, PCR, etc, where small volumes are used. Both fixed capacity and variable volume pipettes are available.

How does an air displacement pipette work?
The air displacement pipette (ADP) performs air displacement through an internal adjustable ball screw. The drive is the coreless blushless DC motor with encode. The ADP picks up a disposable tip, the liquid is aspirated from liquid reservoir to tips then to another reservoir.

Working Principle and Selection of Miniature Diaphragm Pump(2024年04月16日)

enkeyto — 2024-04-10T16:26:45+0900

https://en.keyto.com/working-principle-and-selection-of-miniature-diaphragm-pump.html

Working Principle of Miniature Diaphragm Mechanical Device
The circular motion of the motor makes the diaphragm inside the pump reciprocate through mechanical devices, thus compressing and stretching the air in the pump cavity (fixed volume), and under the action of the one-way valve, a positive pressure is formed at the outlet (the actual output pressure is related to the resistance of the pump outlet and the characteristics of the pump); A vacuum is formed at the water pumping port, resulting in a pressure difference with the outside atmospheric pressure. Under the action of pressure difference, the water is pressed into the water inlet and then discharged from the water outlet.

Under the action of the kinetic energy transmitted by the motor, water is continuously sucked and discharged, forming a relatively stable flow.

Selection of Miniature Diaphragm Pump
The mini diaphragm pump is generally driven by a low-voltage DC brush motor, and the circuit should be anti-parallel diode freewheeling. When there is no liquid in the pump, it is similar to the no-load of the motor (the winding current of the pump motor is relatively low), and the diaphragm is soft plastic, which has no large mechanical stress and can be dry-pumped.

In the case of a DC low-voltage power supply, use a miniature diaphragm pump.


Can a solenoid pinch valve regulate flow?
The solenoid pinch valve cannot be used to regulate flow because it is only available in two states, fully open or fully close, and the degree of opening cannot be adjusted at will.

How doe s a pinch solenoid valve stop flow?
Two types of solenoid pinch valves are available: N.C. and N.O.

Normally open valve(N.O.): the solenoid is powered to drive the pressure plate action, then the pressure plate clamps hose tightly, so as to stop the flow. Normally open valve(N.C.): the initial state of a normally close valve is that of a stop-flow, and the stop-flow principle is the same as that of a normally open valve. The difference is that normally open valve stops flow when powered on and normally closed valve stops flow when powered off.

Differences Between Micro Diaphragm Solenoid Valve and Miniature Proportional Valve
Miniature Proportional Valve

A proportional valve is a new type of hydraulic control device. On the ordinary pressure valve, flow valve, and directional valve, the proportional electromagnet is used to replace the original control part to continuously and proportionally control the pressure, flow, or direction of the oil flow according to the input electrical signal. Proportional valves generally have pressure compensation performance, and the output pressure and flow can not be affected by load changes.

The proportional valve performs continuous step control according to the proportion and automatically compensates and controls the target according to the information collected according to the actual situation. The valve opening direction, opening amount, or spring setting force are all follow-ups, realizing a series of continuous and controllable follow-up actions.

Micro Diaphragm Solenoid Valve

The ordinary solenoid valve is a single action on-off valve, which can't perform continuous step control in proportion. Its valve opening direction, opening amount, or spring setting force are all fixed and cannot be changed according to the actual situation.

FAQs of Micro Diaphragm Solenoid Valve

What is the use of micro diaphragm solenoid valve?
Solenoid valve function: it is a cut-off valve that automatically opens and closes by electromagnetic force. It is mainly used as an automatic basic device for controlling objects and belongs to the actuator. Usage: it can be used in an industrial control system to regulate medium direction, flow, speed, and other parameters, so it is widely used in various production fields. Most of Keyto's solenoid valves are used in IVD or medical terminals.

How does a micro diaphragm solenoid valve work?
When the solenoid valve is in the closed state, under the action of the spring force and the gravity of the valve core, the sealing surface of the valve core sealing block is in close contact with the annular plane of the valve seat. Since the annular plane of the valve seat is tiny, the sealing surface of the valve core forms a small annular sealing belt, which plays a good sealing role. When the coil of the small solenoid valve is energized, the valve core moves upward against the pressure of the spring force and the self-weight under the electromagnetic energy. At this time, the sealing surface of the valve core is separated from the valve seat, the pipeline is connected, and the medium flows out through the valve core hole; When the coil is powered off, the attractive electromagnetic force of the coil disappears, and the valve core moves downward under the action of the spring force to close the air circuit.

Does the micro diaphragm solenoid valve require pressure?
The micro diaphragm valve needs to be energized through the circular motion of the motor and the mechanical device to form pressure so that the diaphragm inside the pump makes the reciprocal motion and the air in the pump cavity compress and stretches. Under the check valve, a positive pressure is formed at the drainage port; a vacuum is created at the pumping port, thus forming a pressure difference with the outside atmosphere. Under this pressure difference, water is pressed into the water inlet and discharged from the drainage port. Under the action of kinetic energy transmitted by the motor, water is continuously drawn in and discharged, forming a relatively stable water flow.

Functions & Applications of Rotary Shear Valves

The functions and applications of rotary shear valves are as follows:

Keyto rotary shear valve is a new type used in the hydraulic field, especially in connection with a multi-channel rotary cutting valve and a hydraulic system. The utility model can reduce the diameter of the valve body and the volume of the rotary shear valve under the same working conditions.

During its operation, the drive device drives the adapter shaft to rotate, and the valve element assembly rotates to make the second liquid inlet channel align with the liquid inlet through the hole on the valve body so that external liquid can enter the valve head. The liquid inlet through-hole on the valve body is arranged in several rows along the radial direction of the valve body, which makes efficient use of the space of the valve body. Under the same working conditions, the diameter of the valve body is effectively reduced, and the volume of the rotary cut valve is reduced.
