About The Term Explanation Of Pipette
As a kind of common laboratory tool, pipettes are used to transfer liquids from one container to another in exact and measured volumes. They may seem like very important tools, but pipettes actually are a great invention to scientific research. Before they came to use about 50 years ago, scientists sometimes had no other choices but did the same job with their mouths.
We can find two types of Pipettes come: volumetric and measuring. Working as simple glass tubes, volumetric pipettes are used to transfer the specific amount of liquid. Measuring pipettes are adjustable, and you can draw up exact volume of liquid as you desire. You should place the pipette 1/4th of an inch from the bottom of the container when you draw it in a liquid to prevent damage. After you draw up the required volume of the liquid , you’d better gently tap the side of the pipette to remove excess droplets and hold the pipette at a 10 to 20 degree angle when you dispense.
Hawach pipettes include both electronic and mechanical types. We also have pipette stand ( linear and round), and pipette tips which are divided into advanced pipette tips, standard pipettes, and advanced filter pipette tips. Manufactured from innovative materials, Hawach guarantee all the products high temperature and pressure resistance, high accuracy, and easy-operating.
When purchasing a pipette, you need to pay attention to the following points: pipette range, tip and disinfection method.
The range of the pipette can be fixed and adjustable, such as 5 microliters fixed, that is, the pipette can only shoot 5 microliters of liquid at a time.
5-50 microliters adjustable: you can adjust from 5, 6, 7 all the way to 50, each time the liquid is set by you.
Then there are single channels, 8 channels and 12 channels. 8 channels are that you can make 8 water jets at a time, and 8 can inject liquid together.
If you buy a multi-channel pipettes, you must choose good quality tips to ensure the accuracy.
Finally, the pipette can be fully disinfected and half disinfected. Half disinfection means to remove the components and place in the disinfection cabinet for disinfection. Full disinfection requires no disassemble, which is more convenient.
HAWACH pipettes have comprehensive specifications, good quality and high cost performance. It can be electric or manual. For the manual type, there are three different series, standard series, advanced series, advanced plus series. The first two series are semi-sterilized or the last one is fully sterilized which is more suitable for biological industry.
In order to ensure the final use of the quality requirements in the product development process, all materials used and the manufacturing process are meticulous. Hawach pipette is constructed not only by using recyclable, biodegradable packaging materials, but also by using updateable, durable materials, which make it to be the most environmentally friendly pipette on the market. This also ensures the long service life and the most environmentally friendly recovery of the pipette.
Hawach constantly pursues a single, convertible, fixed or variable capacity pipette, and all efforts are reflected in details. The large button design makes it easier to exit the suction nozzle and the liquid-absorbing and discharging process can be completed only by a small force. The double O-ring design provides the most excellent nozzle seal, and all brands of suction nozzles are compatible for use.
Besides, a nozzle connection base of a metal material is included, thus the incidence of breakage due to accidental fall and suction nozzle loading is minimized. The lockable capacity control button reduces the torque demand of 50%, and the capacity change display is fully visible when the capacity is adjusted.
