Notice of participation in "VIETWATER 2025" from Wednesday, October 22, 2025, to Friday, October 24, 2025. {Case studies are also being introduced!!}

Exhibits high airtightness and valve seat sealing performance! Excellent in corrosion resistance, chemical resistance, and cleanability.

A diaphragm valve is a type of valve that has a structure for opening and closing the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Wear-type diaphragm valve: Type 400" is the basic form of a diaphragm valve that has a weir in the flow path. The fluid passage section is streamlined and has no pocket areas, which minimizes liquid accumulation and provides self-cleaning properties. Due to the valve's structure, it exhibits high airtightness and seat sealing performance. There is a wide variety of materials available for the body and diaphragm, allowing it to accommodate a broad range of fluids. ▼Applicable fields: Chemicals, environmental and water treatment, steel, shipping, pharmaceuticals, food, semiconductors, power generation, etc. *For more details, please refer to the catalog (P6–P14) or feel free to contact us. (The English and Chinese versions of the catalog can be downloaded from the catalog page of the special website below.)

The flow path is close to straight, with a structure that has low pressure loss and minimal liquid accumulation! It is suitable for fluids containing sludge, suspended solids, and more!

A diaphragm valve is a type of valve that has a structure that opens and closes the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Straight Type Diaphragm Valve: 500 Series" features a flow path that is nearly linear (straight), resulting in a structure with minimal pressure loss and liquid accumulation. It is suitable for fluids containing viscous fluids, fibrous fluids, slurries, sludge, and suspended solids. ▼ Application Fields: Water treatment plants, final treatment facilities, etc. *For more details, please refer to the PDF materials or feel free to contact us.

Mettler Toledo will hold an online seminar titled "Taking Pipetting to the Next Stage." In this webinar, we will explain techniques and tips for selecting the appropriate pipette and using it effectively, based on Good Pipetting Practice, which is essential for pipetting operations. By learning the proper selection and usage of pipettes, which are widely used in experiments in biology and life sciences, you will be able to perform pipetting operations with greater accuracy.

Mettler Toledo will hold an online seminar titled "Pipetting Difficult Liquids." Are the samples you pipette aqueous solutions like buffers, or are they highly volatile, viscous, corrosive like acids and bases, or prone to foaming liquids? For accurate pipetting, let's use the optimal equipment and techniques according to the type of liquid.
