PTFE centrifuge tube/digestion tube, with threaded mouth and threaded sealing cap to prevent sample leakage. 

Especially when it is used for radioactive or highly corrosive samples, it is very important to prevent sample leakage. 

The threaded tube cap has another function to prevent the sample from volatilizing and to support the centrifuge tube to prevent the centrifuge tube from deforming. 

According to the needs of the experiment,it can be used in different equipment,such as centrifuge, microwave digestion instrument, acid drier and so on. 

Feature: 

After heating and pressure increase,it can quickly and without damage to dissolve samples that are difficult to dissolve under normal conditions and samples containing volatile elements 

Can shorten analysis time and reliable data 

Resistant to acid, alkali, etc. 

Sample pretreatment to digest heavy metals, pesticide residues, food, silt, rare earths, aquatic products, organic matter, etc. 

Applications: 

Mainly used for the separation and preparation of various biological samples. 

The biological sample suspension is placed in a centrifuge tube. Under high-speed rotation, due to the huge centrifugal force, suspended tiny particles (such as: Precipitation of organelles, biological macromolecules, etc.), settle at a certain speed, so that they can interact with the solution. 

It is also widely used in Graphite digestion instrument, microwave digestion instrument, and other equipment to digest difficult-to-dissolve samples such as heavy metals.
