Distillation is a physical method of assorting mixtures depending upon the difference in the boiling point of the component substances. In simple words, the working principle of distillation is to heat a mixture at a specific temperature, collect the hot vapors, and condense to separate the component substance.

During ultrasonication, power is transmitted into the liquid. This leads to turbulences and friction between the layers of liquid. This is the reason why there is a generation of heat. Effective cooling is used for the reduction of heat. Smaller samples can be cooled by keeping them in an ice bath.

Feb 10, 2022 The samples were exposed to the X-ray beam at 2θ angles ranging from 2 to 60 running at 45 kV and 40 mA, employing Cu Kα radiation (λ = 1.541 ) at a rate of 2 min –1. To evaluate the relative crystallinity degree (RCD), the total curve area ( I t ) and the area under the peaks ( I p ) were determined using the software offered by ...

Incubate samples 30 sec on wet ice between pulses. Optimal conditions required for complete lysis of nuclei can be determined by observing nuclei under light microscope before and after sonication. HeLa nuclei were completely lysed after 3 sets of 20-sec pulses using a VirTis Virsonic 100 Ultrasonic Homogenizer/Sonicator set at setting 6 with a ...

May 21, 2020 Studying isolated pieces of DNA is nearly impossible. Large amounts of a sample of DNA are necessary for molecular and genetic analyses. Sometimes called molecular photocopying, conventional polymerase chain reaction (PCR) is a technique used to amplify (replicate) trace amounts of DNA and RNA from a sample.

Oct 06, 2020 A full-Brix scale digital refractometer, the IC-300058 is designed to measure aqueous samples on its scratchproof sapphire lens. It can distinguish Brix percentage concentrations between 0 to 95%. In addition to the Brix scale, you can measure and display readings from the refractive index, temperature, dextran, fructose, glucose, lactose, and ...

Rotary evaporators, commonly known as rotavapors, rotavaps or rotovaps, are extremely valuable to a number of downstream applications requiring efficient distillation & solvent removal.Often combined with a vacuum pump, rotary evaporators are used to remove solvents from samples through evaporation. During this process, rotary evaporators reduce the pressure within the …

Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum; indeed, historically, spectroscopy originated as the study of the wavelength …
