An Essential Tool For Lab Experiment-Bottle-Top Dispenser
Hawach bottle-top dispenser is an instrument for measuring liquid medicine. To ensure that your bottleneck dispenser has a long service life, some maintenance, and cleaning work can be done in the following situations: the pipette piston is not flexible; the dispensing of some restrictive solutions (such as high concentration of salt solution and Concentration of alkaline solution); before changing the dispensing reagent; before sterilizing the bottle mouth dispenser; changing the pipes (suction pipe, return pipe and dispensing pipe) of the bottle mouth dispenser; before storing for a long time.
Hawach is committed to providing international laboratories and industrial users with products that meet the highest quality standards, making scientific research more convenient, allowing scientists and technicians to focus more on actual work.
According to the different needs of customers, we provide professional technical support and tailor-made the highest quality system solutions, including pre-sale selection, after-sale installation guidance, and maintenance. We attach great importance to good after-sales service and rely on excellent product quality and excellent service quality to win the long-term trust of partners.
The bottle-top dispenser is an instrument for measuring liquid reagents. It is widely used in the fields of biology and chemistry, as well as clinical medicine, industry, and commerce lab due to its reliability in safety, convenient operation and precise calibration. The early bottle-top dispenser was very simple, but with the development of technology, this instrument also added electronic instruments to facilitate the operation based on the early manual calibration operation, and also made technical adjustments on other accessories such as interfaces, making the instrument more durable.
Commonly used bottle-top pipettes can be roughly divided into digital and cursor types. According to its applicable liquid properties, it can also be divided into standard type, organic type, and hydrofluoric acid type. The standard type is suitable for one side of acid and alkali, low concentration of strong acid and alkali, and salts, such as H3P4, H2SO4, NaOH, KOH, etc. Organic type is suitable for organic matter and high concentration of acids and salts, such as HCL, HNO3, TFA, THF, etc. The hydrofluoric acid type is especially suitable for hydrofluoric acid, and there are some other types, such as simple type.
Bottle dispensers produced by HAWACH can be used for general acids and alkalis and low concentrations of strong acids and alkalis and salts, such as H3PO4, H2SO4, NaOH, KOH, etc., made of ETFE, FEP, PP, and other materials. Fine adjustment can be made according to the viscosity of the liquid with PFA seals the sliding piston to prevent blockage. Clean piston design can prevent liquid crystallization and the internally circulated safety piston prevents liquid waste when filling liquid. The maximum pressure resistance is 500mbar, the maximum viscosity resistance is 500mm2/s, the maximum temperature resistance is 40℃, the maximum liquid density is 2.2g / cm3, and the whole can be autoclaved.
1. Safety: made of optical glass, Al2O3, ETFE, PFA, FEP, PTFE, platinum-iridium alloy, safe to use.
2. Convenience: from setting the volume to sucking and pipetting, it can be done with one hand.
3. Wide application: suitable for various acids, alkalis, salts and organic solvents (hydrofluoric acid is also applicable)
4. Durability: all materials in contact with the solvent are PFA, which has good drug resistance
5. Maintainability: all components are a modular design, easy disassembly, and maintenance
