Nanjing Binzhenghong Instrument Co.,Ltd is a professional laboratory product manufacturer which mainly has laboratory products based on PTFE/ PFA/ FEP and other materials, such as: beaker/ reagent bottle/ stirring bar/ tweezers/ funnel/ volume flask/ crucible/ stirring rod/ water tank/ reaction bottle/ washing bottle/ The measuring cylinders/etc.
Our products are sold all over the world (such as CUG, IGCAS, SGS, etc. )and are well received by experimenters in the semiconductor, electronics, and pharmaceutical industries, and are widely used in the chemical industry.
High temperature resistance:
The operating temperature range is wide, usually up to -200ºC~250ºC, and it can withstand experimental operations in high temperature environments.
Corrosion resistance:
It has excellent corrosion resistance and can resist corrosion from most chemicals, including acids, alkalis, solutions, organic reagents, etc., and is suitable for various chemical reactions.
Chemical inertness:
Its surface has good chemical inertness and is not affected by most chemicals, ensuring the accuracy and reliability of experimental results.
Non-adhesiveness:
The surface is smooth and has very low surface adhesion. It is not easy to adhere to chemicals, pollutants or sediments, and is easy to clean and remove residues.
Mechanical strength:
Although polytetrafluoroethylene is a relatively soft material, it has sufficient mechanical strength over a wide temperature range and can withstand certain pressure and impact.
Design features:
It usually has a round belly and thin neck appearance, and the narrow mouth is designed to prevent solution splashing or reduce evaporation.
Equipped with a stopper, the inner wall is smooth for easy disassembly and cleaning.
There are multiple specifications such as single neck, three necks and four necks, which can be selected according to experimental needs.
