Vicat softening temperature or Vicat hardness is the determination of the softening point for materials that have no definite melting point, such as plastics. It is taken as the temperature at which the specimen is penetrated to a depth of 1 mm by a flat-ended needle with a 1 mm 2 circular or square cross-section.

Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period. [1] [2] [3] Before the mid-nineteenth century such tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a ...
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.
The Thiele tube, named after the German chemist Johannes Thiele, is a laboratory glassware designed to contain and heat an oil bath. Such a setup is commonly used in the determination of the melting point or boiling point of a substance. The apparatus resembles a glass test tube with an attached handle.
Instrument Uses Autoclave: used for sterilization of glass ware and media Auto-destruct syringes: specimen collection Bijou bottle: a cylindrical small glass bottle with a screw cap used as a culture medium holder
Tissue bath or organ bath or Dale's apparatus: used in full tissue experiments, for example using guinea pig ileum mainly used in pharmacology for application of drugs to these tissues. Sahli Haemoglobinometer: an old but rapid and simple method of hemoglobin estimation in the laboratories.
Note the hose barb pointing right for attaching a vacuum source. A Büchner flask , also known as a vacuum flask , [ 1 ] filter flask, suction flask, side-arm flask, or Bunsen flask , is a thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck.
