Aesthetic Syringe And Solid Connector Principle And Use Of The Introduction
Dr.c | Updated: Aug 14, 2017

Aesthetic Syringe And Solid Connector principle and use of the introduction
What are Aesthetic Syringe And Solid Connector? Aesthetic Syringe And Solid Connector are essential tools for biochemical testing or molecular biochemical testing and are widely used in many fields. Users for beautiful syringes and solid connector principle and the use of methods need to master, the following small wall to come to the specific introduction of beautiful syringes and solid connector principle and use, hoping to help everyone.
Aesthetic Syringe And Solid Connector principle
The beautiful syringe and the solid connector are a kind of precision liquid collection device which can adjust freely in a certain capacity range. The basic principle is to rely on the movement of the piston in the device. The moving distance of the piston is controlled by the adjusting wheel Actually, the push button drives the push rod to move the piston down to remove the gas from the piston chamber. After the release, the piston in the role of the return spring to restore the original position, thus completing a liquid absorption process.
Use of Aesthetic Syringe And Solid Connector
First, the standard operation
Suitable liquids: water, buffer, diluted salt solution and acid-base solution.
1) press the first gear, vertical into the liquid a few millimeters.
2) Slowly release the control button, otherwise the liquid into the tip of the tip will lead to liquid inhalation into the Aesthetic Syringe And Solid Connector internal inhalation volume reduction.
3) when playing the liquid and have a certain angle, first press to the first file, a little pause 1s, the remaining liquid after the accumulation, and then press the second gear will be the remaining liquid all out.
Second, the removal of viscous or volatile liquids
In the removal of viscous or volatile liquid, it is easy to lead to larger volume error. In order to improve the accuracy of pipetting, the following methods are recommended:
1) before the first liquid with liquid pre-wetting the tip of the internal, that is, repeatedly hit the liquid several times to make the tip pre-wet, liquid or liquid discharge when the best stay a few seconds. Especially for the removal of large volume of liquid (such as 1000 ~ 1), it is recommended to pre-wet the nozzle and then removed.
2) the use of reverse phase fluid method: suction to the second gear, slowly release the control button, press the press when the first file can be, part of the liquid residue in the tip.
Third, the common wrong operation
1) When the liquid is absorbed, the beautiful syringe and the solid connector itself are tilted, resulting in pipetting is not accurate (should be vertical aspiration, slow suction slow release).
2) When the tip is assembled, the force is too high, which makes it difficult to remove the tip (without too much force, choose the tip that matches the beautiful syringe and the solid connector).
3) Place a beautiful syringe with a residual liquid tip and a solid connector (the Aesthetic Syringe And Solid Connector should be hung on a Aesthetic Syringe And Solid Connector).
4) Remove small volume samples with a large range of Aesthetic Syringe And Solid Connector (should choose a range of Aesthetic Syringe And Solid Connector).
5) Press directly to the second stage (should be operated according to the above standard method).
6) Use acetone or corrosive liquids to clean the beautiful syringe and the solid connector (should be operated with reference to the correct cleaning method).
Aesthetic Syringe And Solid Connector purchase guide
1. Product performance, ie, the accuracy and repeatability of Aesthetic Syringe And Solid Connector For the vast majority of users, it is difficult and unnecessary to test product performance before purchasing. Therefore, mainly based on the technical data provided by the manufacturer. But here is to explain two points: First, do not easily believe that the seller's verbal commitment, we must consult the manufacturer to provide written materials; Second, in the global aesthetic syringes and solid connector market impact on the larger brands, such as The United States DRUMMOND, SOCOREX, EPPENDORF and GILSON, etc., the technical data provided by the higher credibility.
2. Reliable and durable products in this regard, mainly depends on the Aesthetic Syringe And Solid Connector used in the material. For the shell, there should be a high impact resistance, corrosion resistance and low thermal conductivity (such as PVDF material); for the piston, the current market mainly stainless steel, ceramic and plastic three materials. Stainless steel mechanical properties, long life, but not suitable for strong acid and alkali of the pipetting; ceramics have a high corrosion resistance, but poor mechanical properties. Of course, high-quality materials often mean higher prices, so the need to consider the purchase price and life factor.
