(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.
Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass.
Beaker (glassware) Many of these flasks can be wrapped in a protective outer layer of glass, leaving a gap between the inner and outer walls. These are called jacketed flasks; they are often used in a reaction using a cooling fluid.
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 RCA clean is a standard set of wafer cleaning steps which need to be performed before high-temperature processing steps (oxidation, diffusion, CVD) of silicon wafers in semiconductor manufacturing.
A microscope slide prepared in 1855 containing reference specimens from the inner mucosa of the small intestine of a cholera victim.. The origin of the concept was pieces of ivory or bone, containing specimens held between disks of transparent mica, that would slide into the gap between the stage and the objective. [1]
Rhoticity – GA is rhotic while RP is non-rhotic; that is, the phoneme /r/ is only pronounced in RP when it is immediately followed by a vowel sound. [5] Where GA pronounces /r/ before a consonant and at the end of an utterance, RP either has no consonant (if the preceding vowel is /ɔː/, /ɜ:/ or /ɑː/, as in bore, burr and bar) or has a schwa instead (the resulting sequences being ...
A utility clamp is a laboratory apparatus resembling a pair of scissors.The screw in the middle works as the wide adjustment of 2-prong. [1] It is composed of 3 parts: 2-prong adjust, metal rod, and clamp down (the clamp is attached to the ring stand for adjusting the height).
