It is the basic operation in the Novel Coronavirus testing process
Reagent preparation, nucleic acid extraction, PCR pretreatment
All processes are dependent on pipetting
In the process of pipetting
Disturbance of a liquid, including flow and splashing
Hanging wall, blowing out residual liquid and other actions
Are prone to causing aerosols.
“What are aerosols?”
“The so-called aerosol is a colloidal dispersion system formed by the dispersion and suspension of solid or liquid particles in the gaseous medium.”
Aerosols will enter the pipette with channels formed by negative pressure, and finally diffuse in two ways:
The first kind of aid: When you learn the next sample, you enter the next sample. This is commonly called sample cross contamination.
Second: Diffusion into air, which adversely affects the operator when the sample is hazardous.
How to Cope
Use appropriate pipetting tools
Can counter the adverse effects of aerosols
Poroyal Suction filter element
It can effectively block aerosol diffusion during operation
Prevent cross-contamination of novel coronaviru
Four advantages of Pipette Tips filters
One, effective barrier aerosol
Pure ultra-high molecular weight polyethylene (UHMW-PE) is used as raw material, which is made by a unique process and has hydrophobicity. A solid barrier is formed between aerosol and liquid to eliminate potential cross contamination of sample and pipette that could affect the results.
Two, RNase /DNase free
High temperature processing, each process to ensure no RNase, DNase pollution. Can be used for PCR, radioactive, biological toxic, corrosive, volatile sample adding operations.
Three, to meet the strict appearance requirements
Blend blend biological filter element production experience for many years, precision mold processing, no burr/burr; Moderate elasticity ensures a perfect fit with the inner diameter of the suction head and uncompromising appearance accuracy even in the smallest diameter.
Four, a variety of specifications for choice
Adapt to the market common various brands of suction head, to meet the needs of differentiated product design customers. At present, our specifications are still constantly updated, please pay attention to…
