Method is almost the same.Liquid-transfering gun category precision instrument uses and is intended to careful when storing, prevents from damaging, avoid influencing its range.
Two kinds are broadly divided into using the method that liquid-transfering gun carries out liquid relief at present, one is advance liquid relief methods.It will with thumb
Button is pressed to the first rest point, and then come up button Aligning control, then presses button to the first rest point and liquid is discharged, slightly stop
A moment continues to touch the button to the remaining liquid of the second rest point blowout.Last release button.Second is that reverse pipetting method, this method is generally used
In transfer high-viscous liquid, the liquid of bioactive fluid, liquid easy to foaming or denier, principle is exactly first sucking more than setting
The liquid of range first presses lower button to the second rest point, come up button without the liquid that blowout is remaining when transfer liquid
To origin, then button is pressed to the discharge of the first rest point and sets the liquid of range, continued to keep to pin button and stop positioned at first
Point (must not be pressed) down again, remove the pipette tips of residual liquid, abandon it.No matter which kind of liquid-transfering gun is provided with a pipette tips.
Existing liquid-transfering gun, if a pipette tips can be provided simultaneously with variable capacity or fixed capacity, that means that
A changeable fluid piston and a fixed range piston are provided simultaneously in a liquid-transfering gun.This means that the liquid-transfering gun provides
Two kinds of functions.Not only each pipette tips carry fixed capacity piston to some liquid-transfering guns, but also also have other fixed pistons can be with
In this pipette tips, but nonetheless still it cannot solve to need replacing pipette tips every time to draw asking for different reagents
Topic.For example the case where several different reagents are separately added into multiple samples can be encountered in an experiment, in liquid-transfering gun limited amount
In the case of, or in order to avoid using different liquid-transfering guns caused by error, need to replace pipette tips repeatedly, certainly will thus operate
Cumbersome, waste pipette tips, and be also easy to introduce pollution.
