An evaporative cooler is also known as a swamp cooler. Water is held in a tray at the bottom of the device and pumped up to the distributor. It then trickles down across the cooler media pad to create an evaporative effect. A fan motor then turns a turbine that blows across and through the media pad to send cool air out.
Apr 11, 2016 If your vapor temperature is high enough, you can simply use water. You can use a recirculating chiller to cool the water or you can simply connect the condenser to a tap. Don't forget the Rule of 20 - you want the coolant to be at least 20C cooler than your vapor temperature. If you need your coolant to be near or below 0C you cannot use ...

Feb 03, 2016 Rotary evaporators, which chemists fondly refer to as rotovaps, are used to swirl a sample in a round-bottom flask like a wine connoisseur swirls an expensive glass of Bordeaux. But instead of trying to draw out the bouquet and taste as a connoisseur would for wine, chemists use rotovaps to remove solvents from a completed organic reaction, leaving the desired …
In close cooperation with users, we developed the Hei-VAP series of rotary evaporators with an emphasis on the essentials: well thought-out details with a focus on features and functions to facilitate everyday laboratory work. Versatile combinations with glassware and extensive accessories offer the right configuration for every application.
Jul 10, 2021 A rotary evaporator is used to remove the unnecessary solvents and eliminate solvent bumping. The centrifuge works by lowering the pressure of the chamber, which also decreases the boiling point of the samples. This causes the solvents to be evaporated, concentrating the particles to be separated. Types of centrifugation. 1. Analytical ...

May 16, 2017 The filtrate which obtained as dark blue solution was tested with three heaped spatula of SnCl2 and two layers of yellow solution were formed. This indicates an extra ferrocene left in the filtrate and they were later brought to rotary evaporation to remove the solvent. The crude ferrocene obtained was later assembled and sublimed.
mixture for 45 min. Cool down to room temperature. Filter and transfer the filtrate to a 250-mL round-bottomed flask. Repeat the extraction one more time. Combine the filtrates. Evaporate the combined filtrates to dryness at reduced pressure in a rotary evaporator. Dissolve the residue in ethanol (50%). Transfer the extract to a 10-mL ...

R-1050 rotary evaporator’s rotary bottle maximum capacity is 50L, receiving bottle’s maximum capacity is 30L, rotate speed is 0-90r.p.m, motor power is 250W. RE-5003 rotary evaporator (evaporating bottle volume＞10L) is equipped with double condenser (main and vice condenser), which has better condensation effect and higher recovery rate.
Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.
