PTFE pure white corrosion resistant tweezers
PTFE tweezers are used to clamp blocky , metal particles, solar silicon chips, lithium chips, etc. under harsh conditions. There are two types of fixed pillars and non fixed pillars, and they can be processed into sharp, flat, serrated, etc. It is used for clamping blocky drugs, solar silicon chips, etc. Tweezers with fixed pillars are not easy to slip when picking up objects, which is convenient for experiment.

Laminated glass is one kind of safety glass, and when glass breakage, glass fragments adhering to the interlayer, it can be against forced entry, and avoid fragment damage.
Sentryglas plus (SGP ) laminated glass ,0.89mm/1.52mm/2.28mm
The main character:
Stronger Performance : SGP glass is five times harder than PVB laminated glass, SGP film can let glass keep the shape ,without fall down.� SGP is suitable to use in stairs, flooring and overhead glazing, laminated glass , with outstanding post-breakage resistance to creep and collapse.
Higher Transparence:� SGP film yellow index is only 10-25% of clear PVB ,it is best choice for low iron laminated glass process.
Flexible UV option : SGP is good at both UV transmitting option and as traditional UV blocking interlayer. ,it can be made in a specialty, high-UV transmittance sheet, extremely useful when designing controlled environments for many life species .
FEP, also known as F46, polyperfluoroethylene propylene, Teflon (Teflon), F46, it is a soft plastic, resistant to strong acid and alkali, high and low temperature, mainly used for trace analysis, isotope detection, ICP-MS/OES/AAS analysis and other high-end experiments. The material selection is unique, the background is very low, the contents of metal elements lead and uranium are less than 0.01ppb, and there is no dissolution and precipitation. It is the cleanest experimental analysis utensils at home and abroad. The domestic independent research and development and production break the gap of Teflon series products in the domestic trace analysis market.

1. Product introduction:
In geological and mineral experiments, PFA sample dissolving tanks are widely used. They are a multifunctional experimental tool, also known as dissolution cups, digestion bottles, vials, beakers, etc. These jars are suitable for low and medium pressure sample dissolution and digestion of experimental samples. When used with ICP-MS/ICP-OES analyzers, these jars improve the accuracy of trace-level analysis. In addition, these jars are designed with different bottom shapes according to experimental needs, such as U bottom, flat bottom and V bottom. If you need to use an electric hot plate or a digestion instrument with holes for experiments, you can get better results by combining it with a PFA sample dissolving tank.
