used as a portable autoclave Biological and chemical indicators: Used to ascertain if a certain process has been completed, e.g. spores used in an autoclave are killed if autoclaving is properly done Filters: •Candle filter: used as household water filters and as filters for large particles in the laboratories
a cylindrical small glass bottle with a screw cap used as a culture medium holder Vaccine bath: used to heat vaccine containing medium gently to around 45-55 degrees Celsius during vaccine production Vacuum pump: to draw out the air from any closed chamber before pumping back CO 2, O 2 or N 2, usually for anaerobiosis: VDRL rotator: for VDRL test
In laboratory equipment, a beaker is generally a cylindrical container with a flat bottom. [1] Most also have a small spout (or "beak") to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one milliliter up to several liters. A beaker is distinguished from a flask by having straight rather than sloping ...
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 ...
Presently used in some places where sophisticated optical instruments are not available Haemocytometer: a microscope associated apparatus used for manual counting of cells in body fluids like blood, etc. including for sperm count: Wintrobe's tube: used for ESR (Wintrobe's method), PCV, haematocrit, etc. Westergren's tube and ESR stand
Round-bottom flasks are often used to contain chemical reactions run by chemists, especially for reflux set-ups and laboratory-scale synthesis. [3] Boiling chips are added in distilling flasks for distillations or boiling chemical reactions to allow a nucleation site for gradual boiling. This nucleation avoids a sudden boiling surge where the ...
