What is the quality control test for containers?
Containers are tested by many methods of which commonly used test for glass are Crushed glass test, Whole-Container test, Chemical resistance of test, Water Attack Test etc.
Closure materials are tested by Transparency test Penetrability Fragmentation test Self seal ability test, Extractive test etc..
What is Type 2 glass?
2 Glass types are used for pharmaceutical containers : borosilicate and sodo-lime-silicate glass. … Most perfumery and cosmetics containers are made of sodo-lime-silicate glass. There is no official current requirement on the glass Type or hydrolytic resistance.
How will you define QA?
Quality assurance can be defined as “part of quality management focused on providing confidence that quality requirements will be fulfilled.” The confidence provided by quality assurance is twofold—internally to management and externally to customers, government agencies, regulators, certifiers, and third parties.
What is Type 1 borosilicate glass?
TYPE I GLASS / TYPE 1 Also known as “neutral,” type 1 is a borosilicate glass with good chemical resistance. It is used for pharmaceuticals requiring the least reactive containers. Typical Type I products. tubular glass vials. pre-fillable syringes.
What are 3 types of glass?
soda-lime glass, lead glass and borosilicate glass. These three types of glass make up around 95 percent of the cullet glass used in the production process. The remaining 5 percent of glass is special-purpose glass.
What is example of glass?
Glass is defined as a hard substance made by heating and then quickly cooling sicilates with soda or potash or lime, or something made of this substance. An example of a glass is a container used for drinking wine.
Which glass is used in pharmaceutical industry?
Glass used for pharmaceutical containers is either borosilicate (neutral) glass or soda-lime-silica glass. Borosilicate glass contains significant amounts of boric oxide, aluminum oxide and alkali and/or alkaline earth oxides. Glass is also classified as Type I, II or III based on intended use.
What is pharmaceutical glass?
Glass used for pharmaceutical containers is either a borosilicate (neutral) glass or soda-lime glass. … Borosilicate glass contains a significant amount of boric oxide, aluminum oxide and alkali and/or alkaline earth oxides.
What is glass grain test?
▪ The Glass Grains Test indicates the alkali content of the glass. container, while the Surface Glass Test provides information on the inner. surface durability of the glass container. The Surface Etching Test provides.
What is neutral glass?
Neutral glass is a borosilicate glass containing significant amounts of boric oxide, aluminium oxide alkali and/or alkaline earth oxides. Due to its composition neutral glass has a high hydrolytic resistance and a high thermal shock resistance.
What is glass alkalinity?
The alkalinity of a solution is usually made up of carbonate, bicarbonate, and hydroxides. Similar to acidity, the higher the alkalinity is, the more neutralizing agent is needed to counteract it.
Treatment of unstable Glass:
- Unstable glass formulations can be treated by different ways.
How do you test packaging materials?
3 Testing Methods for Packaging Materials1 Compression Test. Compression testing of packaging materials is done to determine the compression strength of materials such as corrugated box, paper boards, and cans. … 2 Tensile Test. … 3 Vibration Test. … 4 Drop Test. … 5 Impact Test. … 6 Heat Seal Integrity.Oct 31, 2018
What are the 6 types of glass?
6 popular types of glass and their uses explainedFloat glass. Float glass is made using a ‘floating technique’ to create a uniform thickness and superior even appearance. … Toughened glass. … Painted glass. … Patterned glass. … Solar control glass. … Laminated glass.Jan 26, 2017
Which glass is used for non parenteral?
Type III Glass Containers This type of glass container is used for packaging non-parenteral preparations and for packaging certain parenteral products.
What is water attack test?
The principle involved in the water attack test is to determine whether the alkali leached form the surface of a container is within the specified limits or not. Since the inner surface is under test entire container (ampoule) has to be used.
Which type of glass does not give water attack test?
Titrate immediately with 0.02N sulphuric acid using methyl red as an indicator and record the volume. Water Attack Test:– This is only for treated soda lime glass containers under the controlled humidity conditions which neutralize the surface alkali and glass will become chemically more resistant.
What is the importance of conducting tests for containers?
Both primary (consumer) packages and shipping containers have a risk of being dropped or being impacted by other items. Package integrity and product protection are important packaging functions. Tests are conducted to measure the resistance of packages and products to controlled laboratory shock and impact.
What are the 4 types of glass?
There are four main types or strengths of glass:1) Annealed Glass. Annealed glass is a basic product formed from the annealing stage of the float process. … 2) Heat Strengthened Glass. Heat Strengthened Glass is semi tempered or semi toughened glass. … 3) Tempered or Toughened Glass. … 4) Laminated Glass.
What is the difference between glass and Pyrex?
The difference between Pyrex and glass is that Pyrex is tempered glass and used for cook wares whereas glass is mostly used for architecture and furniture. … Pyrex is made by the low coefficient expansion of borosilicate glass whereas glass is blown and pressed to prepare it for the molding process.
How many types of glasses are used in pharma industry?
Glass containers are classified into Type I glass, Type II glass, Type III glass and Type IV glass based on their degree of chemical/hydrolytic resistance to water attack.
