Microscale chemistry (often referred to as small-scale chemistry, in German: Chemie im Mikromaßstab) is an analytical method and also a teaching method widely used at school and at university levels, working with small quantities of chemical substances. While much of traditional chemistry teaching centers on multi-gramme preparations ...
Microscale thermophoresis (MST) is a technology for the biophysical analysis of interactions between biomolecules. Microscale thermophoresis is based on the detection of a temperature-induced change in fluorescence of a target as a function of the concentration of a non-fluorescent ligand.
Pasteur pipettes can also be used for microscale distillation. [13] The liquid to be distilled is placed into a small reaction tube along with a boiling chip and heated to reflux one-half to two-thirds of the way up the inside of the tube. After squeezing the bulb to expel air, a pasteur pipette is inserted into the tube just below the level of ...
An ordinary glovebox, showing the two gloves for manipulation, with airlock on the right. The most straightforward type of air-free technique is the use of a glovebox.A "glove bag" uses the same idea, but is usually a poorer substitute because it is more difficult to purge, and less well sealed.
Surface chemistry cannot be ignored in microfluidics as the interfacial tension becomes a major consideration among microscale droplets. [30] Linas Mazutis and Andrew D. Griffiths presented a method that used surfactants to achieve a selective and highly controllable coalescence without external manipulation. [34]
The initial rate experiment is the simplest to perform and analyze, being relatively free from complications such as back-reaction and enzyme degradation. It is therefore by far the most commonly used type of experiment in enzyme kinetics. Progress curve experiments. In these experiments, the kinetic parameters are determined from expressions ...
The isolation of trimyristin from powdered nutmeg is a common introductory-level college organic chemistry experiment. [8] [9] It is an uncommonly simple natural product extraction because nutmeg oil generally consists of over eighty percent trimyristin. Trimyristin makes up between 20-25% of the overall mass of dried, ground nutmeg.
Microscale Chemistry Experiments (MCE) have additional advantages: · More safety · Suitable from early childhood education [2] [3] up to higher education · Lower costs for chemical substances and equipment · Smaller storage area · Reduced reliance on intensive ventilation systems · Pleasant working atmosphere: “Armchair Chemistry” [4].
