The number one purpose of any mortar and pestle set is to grind solids into fine powders but under conditions that are highly controlled as to not produce any heating effects and to minimize and control any effects due to stretching of sometimes deformable materials. This is probably the most ancient device one is likely to find in a modern scientific laboratory or kitchen. Because of the ability to control the grinding, and also to virtually eliminate contamination from the mortar and pestle set itself, agate is the preferred material and is used in laboratories and the finest kitchens worldwide to prepare delicate sauces and pastes and for the grinding of dried spices and herbs. From a cross-contamination and cleanliness (hygiene) standpoint if in the kitchen, the high density agate is far more desirable than the more porous porcelain which could grow bacteria in the pores and present a health problem. If a mortar and pestle of metal construction is used, it is generally recognized that metal particles enter the ground powder, thereby presenting either a health concern or else a contaminant is precision scientific measurements are to be made on the ground powder.

Details
1) Description

Nylon Membrane filters are made of nylon material, which is known for its excellent mechanical strength and chemical stability. NY membrane filters have good heat resistance and alkali resistance, but are not suitable for certain types of organic solvents and acidic solutions. These membranes typically have a fixed pore size that can be selected based on the size of particles required to be removed, making them very practical in laboratory and industrial applications.

2) Application

Nylon membranes are widely used in biology and chemistry laboratories, especially in sample preparation, purification of liquids and gases, particle analysis, microbiological research, and many other areas. NY membranes are also commonly used in food and beverage inspection, as well as in the pharmaceutical and water treatment industries. Due to their high adaptability and efficiency, Nylon membrane filters have become an indispensable tool in many key industrial and scientific research fields.

3)Features
One of the most commonly used membranes.
Broad compatibility with aqueous and organic solvents, with stable hydrophilicity, not suitable for highly acidic sample
