Highly transparent, elastic thermoplastic polymer with a semi crystalline structure

High thermal stability, wide temperature application range: -200 ℃ to+260 ℃

Almost all chemical drugs have chemical inertness and chemical stability

The water absorption rate is extremely low (<0.03%), and when storing samples in PFA containers, even if the sample concentration is very low, its concentration can be maintained unchanged for a long time.

Smooth, anti adsorption surface, * surface structure

? Specially suitable for trace analysis of elements and storage of low concentration solutions.

At present, the concentration range for trace analysis is ng/g (ppb)~pg/g (ppt). As PFA does not require the addition of additives during the synthesis process and is not affected by the added components, it is very suitable for trace element analysis.

PFAThe most important property of trace analysis is that it has almost no memory effect, ensuring the reliability of the results.

Each PFA product is made from high-purity PFA materials that are particularly suitable for trace analysis.

Precautions for high-pressure sterilization

During the high-pressure sterilization process, containers with screw caps or plugs should be kept open to ensure pressure balance.

?High pressure sterilization of sealed containers can cause deformation and damage to the containers.

During the high-pressure sterilization process, plastic utensils should be placed on a horizontal surface to avoid deformation.

?During the high-pressure sterilization process, plastic utensils should not be applied unilaterally

During the high-pressure sterilization process, mechanical stress should not be applied to the equipment

?For example, do not stack

Do not perform high-pressure sterilization on containers containing residual pollutants or detergents

Not all plastics are suitable for steam sterilization! For example, polycarbonate will lose its tensile strength under high pressure

?Please note the temperature limit for each type of plastic

?Plastic products that can be sterilized under high pressure are labeled with "121 ℃".

During the high-pressure sterilization process, the surface of some plastics may be corroded by chemical substances, causing * turbidity. Some transparent plastics can absorb very small amounts of steam, causing reversible turbidity. this

Turbidity can disappear during the drying process, and using an oven can accelerate its disappearance.

Attention!

Before gas sterilization, dry heat, and microwave heating, all covers and plugs need to be removed.

Heating plastics in a microwave oven

Various plastics can be used in microwave ovens, and more information can be found in the "Physical Properties of Plastics" table on page 148. Regarding this, please pay attention to the chemical and thermal stability of various plastics

Sex and confirm if the special item and its contents match the given temperature. When heating strong acids, strong alkalis, or corrosive solvents, it is recommended to use fluoroplastics. Ensure adequate ventilation (e.g. ventilation)

Cabinet).

Before using plastic laboratory equipment in the microwave oven, please remove the lid and plug
