Mr Atomizer XXL 50L Rotary Evaporator with Dual Condenser & Flasks
Our new Mr. Atomizer XXL 50L series rotary evaporators is now ETL tested to UL/CSA standards, this certification is required by many municipalities, and it also provides a higher standard of equipment safety and lifespan.
SolventVap comes standard with vertical glassware and digital temperature/rotation control, while its optimized bath volume allows for rapid heat-up times. The condenser unit has specially designed glass tubes that utilize surface area extremely efficiently. That’s why our SolventVap evaporators consistently deliver reliable and reproducible process results that are usually reserved for more costly systems. Another important aspect of the SolventVap is the safety features, which includes dry-run protection, water bath over-temperature shut-off protection, and fuse protection.
Rotary evaporator features a specially designed motor and worm gear, which provides constant rotation at speeds from 10 to 180 rpm. As the flask containing the solvent is rotated, it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation, which is caused by the gentle heating from the water bath. The rotating system is fitted with a special seal that allows the apparatus to be placed under vacuum, effectively reducing the boiling point of the solvents and removing the vapor phase, making the process much more efficient. Each unit is also equipped with an easy-to-use vacuum release and a continuous feed system, which allows solvent to be constantly drawn into the rotating flask without needing to stop the operation.
Digital water bath operates from ambient temperature to 99°C (210°F) with PID temperature control stepping at 0.1°C increments. Heating coils are located directly inside the pan for the most efficient heating possible. A built-in overheat protector will shut down power, should the controller fail.
Standard Glassware Set includes 13.2 gallon (50 liters) round-bottomed evaporating flask, 5.28 gallon (20 liters) round-bottomed receiving flask, and vertical condenser. Rotary evaporators with vertical glass condenser are great for distillation of solvents with higher boiling points.
Features
UL 61010-1 and CSA C22.2 certified (optional)
New swivel casters can be adjusted for rotovap to stand securely on uneven floor.
Come standard with a stainless steel 50L evaporating flask carrier with silicone cushions, custom made for XXL 50L series rotary evaporators. This carrier can be placed on top of our 50L SolventVap’s water bath for easy loading and unloading, or used as a flask stand.
Solvent-resistant tefl, PTFE and fluorine double seal gaskets, patent technology ensuring high vacuum.
Continuous receiving system (Auto Shift Valve) allows no drop in vacuum during discharge.
Downward-condensing vacuum connection design ensures safe vacuum operation.
Motorized electric lift water bath for precise control.
Additional manual water bath lift provides you peace of mind in case of power failure.
Easy, straight-forward visual operation with digital speed and temperature display.
PID temperature controller ensures accurate temperature control is maintained.
One year warranty on rotary evaporator except glassware and all sealing gaskets.
Your safety is important to us! Please use caution when operating. Users of glass reaction equipment must take all necessary precautions to avoid contact with rotating parts, particularly entanglement of loose clothing, hair, necklaces, or other jewelry. Under these circumstances, the winding action of the rotating parts can draw the user(s) into the apparatus, resulting in breakage of glassware, burns, and/or chemical exposure. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.

- Ukrainian President Volodymyr Zelensky will meet US President Joe Biden and Vice President Kamala Harris in Washington on Thursday. Leon Neal/Getty Images
CNN
—
Ukrainian President Volodymyr Zelensky’s visit to the White House on Thursday could be his final chance to convince a receptive American president of his country’s war aims.
<a href=https://megaweb-17at.com>megaweb14.com</a>
The precise details of the “victory plan” Zelensky plans to present in separate meetings to President Joe Biden and Vice President Kamala Harris are unknown, having been closely held until they are presented to the American leaders.
But according to people briefed on its broad contours, the plan reflects the Ukrainian leader’s urgent appeals for more immediate help countering Russia’s invasion. Zelensky is also poised to push for long-term security guarantees that could withstand changes in American leadership ahead of what is widely expected to be a close presidential election between Harris and former President Donald Trump.
The plan, people familiar with it said, acts as Zelensky’s response to growing war weariness even among his staunchest of western allies. It will make the case that Ukraine can still win — and does not need to cede Russian-seized territory for the fighting to end — if enough assistance is rushed in.
That includes again asking permission to fire Western provided long-range weapons deeper into Russian territory, a line Biden once was loathe to cross but which he’s recently appeared more open to as he has come under growing pressure to relent.
Even if Biden decides to allow the long-range fires, it’s unclear whether the change in policy would be announced publicly.
Biden is usually apt to take his time making decisions about providing Ukraine new capabilities. But with November’s election potentially portending a major change in American approach to the war if Trump were to win, Ukrainian officials — and many American ones — believe there is little time to waste.

Trump has claimed he will be able to “settle” the war upon taking office and has suggested he’ll end US support for Kyiv’s war effort.
“Those cities are gone, they’re gone, and we continue to give billions of dollars to a man who refused to make a deal, Zelensky. There was no deal that he could have made that wouldn’t have been better than the situation you have right now. You have a country that has been obliterated, not possible to be rebuilt,” Trump said during a campaign speech in Mint Hill, North Carolina, on Wednesday.
Comments like those have lent new weight to Thursday’s Oval Office talks, according to American and European officials, who have described an imperative to surge assistance to Ukraine while Biden is still in office.
As part of Zelensky’s visit, the US is expected to announce a major new security package, thought it will likely delay the shipping of the equipment due to inventory shortages, CNN previously reported according to two US officials. On Wednesday, the US announced a package of $375 million.
The president previewed Zelensky’s visit to the White House a day beforehand, declaring on the margins of the United Nations General Assembly his administration was “determined to ensure that Ukraine has what it needs to prevail in fight for survival.”

“Tomorrow, I will announce a series of actions to accelerate support for Ukraine’s military – but we know Ukraine’s future victory is about more than what happens on the battlefield, it’s also about what Ukrainians do make the most of a free and independent future, which so many have sacrificed so much for,” he said.AlvinBoymngoogle - Ukrainian President Volodymyr Zelensky will meet US President Joe Biden and Vice President Kamala Harris in Washington on Thursday.
