Viewing the Complete Chemical Glass Function with Functions, Types and Constituents
YOGYAKARTA - Chemical glassware (beaker glass) is the most commonly used laboratory tool for research or laboratory activities. This tool is made of heat-resistant borosilicate glass, and does not affect the sample solution, or materials in most chemical reactions. So, what is the function of chemical glassware?
In research activities in the laboratory, the main function of a chemical glass or beaker is to accommodate, mix, and heat liquids. Let's see the complete explanation in the article below.
What is a Chemical Glass?According to the Medilab Exporrats website, a chemical glass is a cylindrical container made of glass or plastic, has a flat base and a small spout for pouring liquids.
Unlike a gourd, a chemical glass has straight sides so it is ideal for mixing, stirring, and heating liquids or solutions.
Chemical glassware is available in various sizes, ranging from 50 mL, 100 mL, to 2 L.
Functions of Chemical GlassesReferring to the e-book entitled Feed Quality Analysis Methods by Prof. Dr. Ir. Hartutik, MP, beakers or chemical glasses have many functions. Some of them are:
Tools for measuring the volume of a solution, especially those that do not require a high level of accuracy. Solution containers to accommodate chemicals To heat liquids Dissolve chemicals. Type of Chemical GlassIn addition to multifunctionality, chemical glasses also have many types, including:
Standard Chemical Glass (Griffin)
Standard chemical glassware has a height of about 40 percent of its diameter. This relatively short chemical glassware model was first designed by John Joseph Griffin, so it is often known as the Griffin cup glassware. In laboratory practice, standard chemical glassware is used to prepare solutions, perform simple chemical reactions, separate liquids through the process of decanting the supernatant, and as a temporary container before the liquid is discarded.
High Chemical Glass (Berzelius)
Unlike standard chemical glassware, high-end chemical glassware has a more towering shape with a height about twice its diameter. This type is known as the Beaker Berzelius and is commonly used in titration processes because of its shape that supports accuracy when adding solutions.
Flat Chemical Glass
The next type of chemical glass is a flat chemical glass which is often referred to as a crystallization glass. This glass is not equipped with a measuring scale like the chemical glass in general. As the name implies, the crystallization chemical glass is used for the process of crystal formation or as a container in the heating method.
Philips Chemical Glass
The last type is the Philips chemical glass which has a shape resembling a Griffin glass. The difference lies in the top which is narrower so that it resembles a funnel or cone. In terms of function, the Philips chemical glass is used for purposes that are almost the same as the Griffin chemical glass in laboratory activities.
Chemical Glass CompositionReferring to the Grainger website, chemical glassware is made from several types of materials with different characteristics, among others as follows.
Glass
Most chemical glassware is made of glass, specifically borosilicate glass. This type of glass contains boron trioxide which makes it able to face drastic changes in temperature. Thanks to these properties, chemical glassware from borosilicate has high durability and can be used at hot temperatures up to around 400 °C.
Plastic
In addition to glass, chemical glassware is also available in plastic materials. Some common types of plastics used include:
Low Density Polyethylene (LDPE) which can survive at temperatures between -100°C to 80°C High Density Polyethylene (HDPE) with temperature resistance of around -100°C to 120°C Polypropylene (PP) which can be used in the temperature range of 0°C to 135°C Polymethylpentene (PMP) which is resistant to temperatures of 20°C to 175°C Polytetrafluoroethylene (PTFE) which has very wide temperature resistance, namely -100°C to 260°CEach type of plastic has a different level of temperature resistance and compatibility with chemicals. Therefore, each requires appropriate treatment and care.
Metal
Metal chemical glassware is generally made from aluminum or stainless steel. The main advantage of this material is that it is not easily broken. Aluminum chemical glassware is able to withstand heat up to 340 ° C, while stainless steel chemical glassware can be safely used at higher temperatures, namely up to 550 ° C.
