Advantages gathering

 

PFA bottles are used for semiconductor, new materials, new energy, geochemistry, trace element detection, and ICP-MS analysis experiments due to their excellent cleanliness and low metal impurity content.

Excellent sealing design, with screw cap to ensure 100% leakproof.

Volumetric flasks are highly transparent, easy to clean, and meet Class A tolerances per DIN EN ISO 1042. Flasks are molded PFA, which is highly resistant to heat and chemical contamination. PFA surface properties offer superior clean-up compared to glass and reduces risk of sample carryover in trace analysis applications. Screw cap design provides reduced contamination risk, compared to traditional stopper design.

PTFE (Polytetrafluoroethylene) wafer cleaning cassettes is high-performance product specially designed for specific applications, widely used in industries such as semiconductors, polysilicon, new energy, new materials, and solar energy.

PTFE semiconductor mask cleaning baskets serve as crucial tools for carrying mask during the cleaning process in semiconductor manufacturing. Mask, also known as photomasks or lithography masks, are key components used in the semiconductor manufacturing process, and their surface cleanliness is vital to the quality and performance of semiconductor products. Therefore, using PTFE cleaning baskets to clean mask plates ensures their surface cleanliness, meeting the stringent requirements of semiconductor manufacturing.

PFA Cassette / Teflon Cassette of wafer can be customized and designed by customers’ request, able to resist strong acid, strong hydrofluoric acid, strong base and heat up to -200~260℃, use to deliver wafers in acid & base process of Fabrication factory.

The PTFE round-bottom flask is widely used in various chemical experiments, such as chemical reactions, distillation, extraction, and concentration. Its exceptional chemical inertness and high temperature stability make this flask an ideal choice for handling corrosive substances and high-temperature reactions.

Teflon flasks usually have a round-bellied and narrow-necked appearance, which is significantly different from a beaker. Its narrow mouth is used to prevent the solution from splashing or to reduce the evaporation of the solution, and can be used with rubber stoppers to connect other PTFE equipment.

Teflon flasks usually have a round-bellied and narrow-necked appearance, distinct from beakers. Its narrow mouth is used to prevent the solution from splashing or reduce the evaporation of the solution, and it can be used with rubber stoppers to connect other PTFE devices. When the solution needs to react for a long time or be heated to reflux, a polytetrafluoroethylene flask is generally selected as a container. The opening of flask does not have the outstanding breach as beaker, and when pouring soln, is easier to flow down along outer wall, so usually all can touch bottleneck to prevent solution from flowing down along outer wall with PTFE stirring rod. Due to the narrow mouth of the flask, it is not suitable for stirring with a PTFE stirring rod. If you need to stir, you can hold the mouth of the bottle and turn your wrist slightly to stir evenly. If it is heated to reflux, a magnetic stirrer can be placed in the bottle and stirred with a heating stirrer. Flasks can be divided into flat bottom flasks and round bottom flasks according to their appearance.
