The Structure And Features Of Electronic Bottle-Top Dispenser

Electronic bottle-top dispenser with safety return valve can be calibrated, and the range can be adjusted. The instrument can be autoclaved at 121 ° C (must be completely cleaned). It has a multi-function return valve, which will not waste a drop of reagent before use. The liquid dispenser uses high-quality materials PTFE, ETFE, PFA, FEP, and has the function of resisting strong acids and alkalis. The discharge tube rotates 360 °, so the reagent bottle label can always be in a visible position. Suitable for any reagent bottle: can be used directly 45mm threaded neck bottle with polypropylene connection for common reagent bottles. In general, the electronic bottle-top dispenser is made up by two parts: the bottle-top dispenser with photoelectric liquid level transducers and the automatic control system. It is easy to operate liquid adding and feeding automatically just by one push of the switch.

In general, the electronic bottle-top dispenser is made up of two parts: the bottle-top dispenser with photoelectric liquid level transducers and the automatic control system. It is easy to operate liquid adding and feeding automatically just by one push of the switch. In terms of further details of the structure, for the part of the bottle-top dispenser, two photoelectric liquid level transducers are installed on the upper and lower parts of the injection syringe. The quantitative volume of liquid adding can be operated by changing the relative distance between the two photoelectric liquid level transducers.

For the automatic control system, it consists of an automatic control circuit, valve drive circuit, and power circuit. This system can add the liquid within the quantitative volume automatically according to the value which is set by the user. After the liquid adding is finished, this system will stop adding and automatically feeding if required.

When talking about the features, firstly, the electronic bottle-top dispenser has a wide range of specifications for the users to choose from. Secondly, it is detected and controlled by the photoelectric liquid level transducer to ensure good reproducibility. Thirdly, it can be widely applied in the laboratories, hospitals and pharmaceutical factories for liquid adding and proportional dilution.

Use Electronic Bottle-Top Dispenser

Firstly, we should connect the tube of reagent bottle with the joint mouth, then turn on the power and push the button of liquid adding to make the dispenser between the upper transducer and the lower transducer fill with reagent. Next, we can adjust the upper photoelectric liquid level transducer or the lower photoelectric liquid level transducer to the same position, and then set the volume at a fixed number (20 ml for example). At last, once we push the button of “send”, the quantitative liquid adding will be operated automatically.

When referring to the correction of dispenser, if the accuracy requirement is not high, we can use measuring implement such as measuring cylinder to make the correction. On the other hand, if the accuracy requirement is high, we can use the microelectronic scales.

During the use of the electronic bottle-top dispenser, we should notice that due to different valve materials, some dispensers are not suitable for organic reagent and acid reagent. And due to the use of photoelectric liquid level transducer, blue solvent is also not available.

Moreover, we should pay attention that there should not be intense light source near or above the dispenser, otherwise normal operation will be affected.
