產品介紹∣CondenSyn Waterless Condenser USA

CondenSyn的性能相當於使用自來水的Leibig型冷凝器。
沒有漏水和潛在氾濫的問題
以不使用水來減少對環境的影響和用水的成本。
清晰可見的回流和易於清潔的設置
適合在真空下使用
每個美國CondenSyn無水空氣冷凝器都是單獨手工製作的
CondenSyn的設計提供了適合的配件來整合到多個系統和應用程序中。
CondenSyn不會因為成本比其他可用系統來的少而讓您失望！
獨特的Asynt CondenSyn概念受歐洲聯盟註冊設計的保護。

在這些測試中，稱過重的內容物會在規定溫度下攪拌一定的時間來測試內容物在冷卻至室溫後，會耗損多少溶劑。

在教學過程中，溫度會被設置為高於研究實驗室所建議的數值，因為學生通常會將加熱元件的溫度設置得高過於溶劑/反應混合物在快速加熱和劇烈沸騰時所需的溫度。
*測量得到的較高水損失是由於其高表面張力導致水滴黏在冷凝器的內部，而不是像其他溶劑那樣全部流回RBF。**建議在使用沸點低於 60°C的溶劑時，將溫差保持在10°C以下來防止發生穿透。而在使用乙醚時，溫度不應超過4°C。

節約金錢和用水

冷凝器的平均用水量為每分鐘2L；該比例已被英國一家主要研究機構確認為其設施中每個冷凝器的平均測量使用量。下表使用的水費是每立方米*1.22英鎊，相較下每立方米浪費1.56英鎊，相當於每公升0.28便士**，一年下來可為您節省不少金錢。

*此商業費率成本來自英國的供水商Anglian Water於2020年3月。

有多種皆適合美國“A”型連接器的尺寸和配件可供選擇：

GB-C-200-A14 200 mm 帶 14/20 插座 (CondenSyn MINI)
GB-C-350-A14 350 mm 帶 14/20 插座
GB-C-350-A24 350 mm 帶 24/40 插座

一所領先的英國大學進行了基於有效長度350mm的CondenSy、帶有約150mL溶劑的250mL圓底燒瓶的獨立測試來評估的研究和教學實驗室的安全使用性能。

可在美國當地購買或直接從Asynt購買。

Performance of the CondenSyn is equivalent to a Leibig type condenser being used with tap water.
No issues with water leakage, and potential flooding
By not using water the environmental impact is reduced as is the costs of water usage.
A tidy setup, clear visibility of reflux and easy to clean
Suitable for use under vacuum
Each CondenSyn Waterless Air Condenser USA is individually handmade
CondenSyn is designed to integrate into multiple systems and applications, with fittings to suit.
CondenSyn is considerably less costly than other available systems, but don’t let that put you off!
The unique Asynt CondenSyn concept is protected by European Community Registered Designs

In these tests the weighed contents were stirred at the given temperature for the stated time to test the loss of solvent, i.e. how much solvent would be lost once the contents have cooled to room temperature.

In a teaching environment the temperature of the heating element is often set higher by students than necessary to ensure a fast heating and vigorous, i.e. clearly visible, boiling of the solvent / reaction mixture. Thus, the temperatures were set to higher values than recommended in research labs for e.g. stills.
*The higher loss of water measured is due to its high surface tension that resulted in droplets of water sticking to the inside of the entire length of the condenser, rather than all running back to the RBF as was observed for all other solvents. **It is recommended that to prevent breakthrough when using solvents below 60 oC boiling point that a temperature differential is kept below 10 oC. With Diethyl Ether then this should be no more than 4 oC.

Saving money and water:

The average rate of water used in a condenser is 2 litres per minute; this rate was confirmed by a major UK research institution as the average measured use per water condenser in their facility. The water costs used below are at $1.22 per cubic metre supply and $1.56 per cubic metre waste which is equivalent to $0.28 per litre.
This commercial rate cost is from a water supplier in the USA, Cal Water in March 2020.

Available in a wide range of sizes and fittings, designed to suit USA “A” type connectors:

GB-C-200-A14 200 mm with 14/20 socket (CondenSyn MINI)
GB-C-350-A14 350 mm with 14/20 socket
GB-C-350-A24 350 mm with 24/40 socket
GB-C-450-A24 450 mm with 24/40 socket

Independent tests were performed by a leading UK University to evaluate the performance for safe use in their research and teaching laboratories. Evaluations were based upon a basic 350 mm effective length CondenSyn, a 250 mL round bottom flask with 150 mL of solvent.

Available to purchase locally in the USA or direct from Asynt.
