Cellulose Acetate Paper Uses

A nitrocellulose slide nitrocellulose membrane or nitrocellulose paper is a sticky membrane used for immobilizing nucleic acids in southern blots and northern blots.

Cellulose acetate paper uses.

It is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards. With high physical strength the membrane filters can be used up to 180ºc are suitable for hot gases and can be sterilized by all methods without sacrificing the integrity of the membrane. The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance. Nitrocellulose is widely used as support in diagnostic tests where antigen antibody binding occurs e g pregnancy tests u albumin tests and crp.

Cellulose acetate became widely used in the automotive industry because of its mechanical strength toughness wear resistance transparency and ease of moldability. This nonflammable mildew proof material is easy to dye and is available in many colors. Cellulose acetate is made by esterifying bleached cotton or wood pulp with acetic acid. Acetate sheets often work with dry erase markers meaning they are easily customizable and reusable.

Cigarette filters are usually made from cellulose acetate fibre but sometimes also from paper or activated charcoal either as a cavity filter or embedded into the cellulose acetate. Acetate paper is available at baking craft and office supply stores. With biologically inert mixtures of cellulose acetate cellulose nitrate mf millipore membranes are widely used in analytical research applications. Manufacturers form it into sheets that are 0 1 mm to 0 5 mm thick.

Cellulose diacetate film was first created by the german chemists arthur eichengrün and theodore becker who patented it under the name cellit from a process they devised in 1901 for the direct acetylation of cellulose at a. Its high resistance to impact made it a desirable material for protective goggles tool handles oil gauges and the like. Acetate paper is a transparent material that is made by reacting cellulose with acetic acid in the presence of sulfuric acid. It is also used for immobilization of proteins in western blots and atomic force microscopy for its nonspecific affinity for amino acids.

In photographic film cellulose acetate replaced nitrate film in the 1950s being far less flammable and cheaper to produce. Cellulose acetate is used as a film base in photography as a component in some coatings and as a frame material for eyeglasses. It was introduced in the early 20th century by film manufacturers and intended as a safe film base replacement for unstable and highly flammable nitrate film. This 25 mm mf millipore membrane is composed of mixed cellulose membrane has a 0 8 um pore size.

Cellulose acetate film or safety film is used in photography as a base material for photographic emulsions. For business applications this acetate film is most often used in an a4 letter format measuring 8 5 by 11 inches and laid on bulb powered overhead projectors to emit a projected image onto a large surface. Cellulose acetate is used as a film base in photography as a component in some adhesives and as a frame material for eyeglasses.
