(B) A tall-form or Berzelius beaker (C) A flat beaker or crystallizer Philips beaker which can be swirled like a conical flask. Standard or "low-form" (A) beakers typically have a height about 1.4 times the diameter. [3] The common low form with a spout was devised by John Joseph Griffin and is therefore sometimes called a Griffin beaker.
Laboratory drying rack can contain and dry up various types of laboratory glassware such as beaker, Erlenmeyer flask, volumetric flask, and graduated cylinder. Laboratory drying rack is usually used to dry up the tube in the laboratory; for example, it can help in drying test tube , boiling tube , and Thiele tube .
A shaker is a piece of laboratory equipment used to mix, blend, or agitate substances in a tube or flask by shaking them. It is mainly used in the fields of chemistry and biology . A shaker contains an oscillating board that is used to place the flasks, beakers , or test tubes.
When using the triple beam balance, it is recommended to start with the lowest level of precision (e.g. 100 gram increments) and then work your way down. For example, if your object weighs 327 grams the 100 gram pointer will drop below the fixed mark on the 4th notch (400g), so you will then need to move this back to the third notch (300g).
A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...
The parts of triple beam balance are identified as the following. [3]Weighing pan - The area in which an object is placed in order to be weighed.; Base - The base rests underneath the weighing pan and can usually be customized to fit on a workbench or set up with tripod legs.
Preparation of microbiological samples in a laminar chamber. A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples, semiconductor wafer, or any particle-sensitive materials.
Laboratory funnels are funnels that have been made for use in the chemical laboratory. There are many different kinds of funnels that have been adapted for these ...
