An Erlenmeyer flask (also called conical flask) is a type of laboratory glassware which consists of an inverted conical base with a cylindrical neck.
However the main difference is that conical flasks may be stoppered using rubber bungs, so as the contents of the flask may be mixed or transported safely.
Conical Flasks are usually graduated for general reference but these meaurements are merely approximates.

 Spectrophotometry - Wikipedia, the free encyclopedia
A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light.
Spectroradiometers, which operate almost like the visible region spectrophotometers, are designed to measure the spectral power distributions of illuminants in order to evaluate and categorize lighting for sales by the manufacturer, or for the customers to confirm the lamp they decided to purchase is within their specifications.
After the sample, the intensity of the remaining light is measured with a photodiode or other light sensor, and the transmittance for this wavelength is then calculated.

 Measuring avocado firmness: Assessment of various methods
The aim of this study was to identify the most appropriate method of measuring ‘Hass’ avocado firmness at both the firm (at harvest) and soft (eating ripe) stages.
This ensured that measurements on the flat side of the fruit were not constantly associated with one type of test.
These instrumental measurements were able to discriminate differences between very hard fruit that tactile assessment was unable to perceive, but hand assessment was able to discriminate differences between soft fruit when the instrumental measurements were unable to measure differences.

Around an antibiotic disc there will be a clear area in which bacterial growth is inhibited; the diameter of this area can be measured to find out whether that bacterial strain is resistant to the antibiotic.
One way to prepare a lawn is to use a 0.5 McFarland suspension of bacteria in saline (this means the saline is made just slightly turbid.) A sterile swab is dipped into this suspension, then it is moved from side to side down the whole agar plate so all the area is covered.

 Conical Compression Springs - Specifications and Spring Design
The solid height of conical compression springs are defined as the length of the spring when under sufficient load to bring all coils into contact with the adjacent coils and additional load causes not further deflection.
Variable pitches in a conical spring are occasionally specified so that all active coils bottom simultaneously, but this is seldom achieved.
There are several methods of analyzing the complex stresses in conical compression springs depending upon the type of pitch, angular relationship of the coils, constant slope, currving contours, and other factors.

 Calorimeter Summary
A calorimeter is a scientific instrument used to measure the heat generated or absorbed in a chemical reaction or physical process.
To measure the amount of heat generated by this process, Count Rumford placed the warm cannon into a tub of water and measured the increase in the water's temperature.
It permits the simultaneous measurement of heat effects that are reversible and not reversible at the timescale of the oscillation (reversing and non-reversing heat flow, respectively).

Obha (1978) proved that the closure of the range of a measure of bounded variation on a sigma-algebra, with values in a Fréchet space with the Radom-Nikodym property, is compact and, if the measure has no atoms, also convex.
If mu is an atomless finite-dimensional vector measure (not necessary finite), then the range of mu is convex, the closure of the range does not contain a line and each compact extreme face of the closure of the range is contained in the range.
