    Bar type ultra low temperature cold trap DW-100-BT

    產品名稱:Bar type ultra low temperature cold trap DW-100-BT

    所屬類別:冷阱

    型號範圍:CBE-9ALHC至CBE-72ALHC

    PRODUCT FEATURES 產品特征:

    Cold traps are specially designed Heat Exchangers designed to trap the condensate. The trap is cooled below a specific temperature range in order to condense valuable or dangerous chemicals. The cold trap works by condensing vapors into a liquid on the traps surface area which is collected in the base of the trap. The colder you get the trap the more stuff can be condensed and trapped. Cold traps are attached to a vacuum system between the vacuum pump and the vacuum chamber in order to prevent solvents and other corrosive compounds from reaching the pump.

    冷阱是專門設計的用於捕集凝結水的熱交換器。陷阱被冷卻到一個特定的溫度範圍以下,以便濃縮有價值或危險的化學物質。冷阱的工作原理是將蒸汽凝結成陷阱表麵積上的液體,然後收集在陷阱的底部。你得到的陷阱越冷,就會有更多的東西被濃縮和捕獲。在真空泵和真空室之間的真空係統上裝有冷阱,以防止溶劑和其他腐蝕性化合物到達真空泵。

    Methods for Cooling

    Ice (water): Ice melts at around 32 degrees which makes it especially well suited for trapping alcohol or other high boiling point compounds. Ice is not cold enough to freeze water in the trap or condense low boiling solvents like Butane. This combined with the availability of ice makes it an attractive option when used to keep contamination out of the pump. Ice keeps the trap cold enough that anything with a boiling point above 50C will be collected in the trap keeping the vacuum pump clean.

    冷卻冰()的方法:冰在32度左右融化,這使得它特別適合捕捉酒精或其他高沸點化合物。冰是不夠冷,以凍結水在陷阱或濃縮低沸點溶劑,如丁烷。這與冰的可用性相結合,使它成為一個有吸引力的選擇,當使用時,以防止汙染的泵。冰保持陷阱足夠冷,任何沸點超過50C的東西都會被收集在保持真空泵清潔的陷阱中。

    Dry ICE: Dry ice is frozen CO2 and does not melt due to CO2’s vapor pressure. Instead frozen CO2 turns directly from a solid to a gas as it sublimates which is why it is called “dry” ice. CO2 sublimates at a much lower temperature than water melts, -109.2 degrees fahrenheit to be precise. However Heat transfer is never 100% efficient and when using pelletized dry ice alone the trap gets down to about -40 fahrenheit. At this temperature highly volatile molecules such as terpenes will collect in the trap along with dangerous solvents such as butane. In High vacuum systems the constantly reducing pressure leads to product loss from the trap, the colder you keep the trap the less that happens. Dry ice Can be used around the outside of the cold trap to keep the terpenes and other valuable components trapped during your vac down process .

    幹冰:幹冰是凍結的二氧化碳,不融化,因為二氧化碳的蒸汽壓力。相反,凍結的二氧化碳在升華時直接從固體轉化為氣體,這就是為什麽它被稱為“幹冰”的原因。二氧化碳以比水的溫度低得多的溫度升華,準確地說是華氏-109.2度。然而,傳熱從來沒有100%的效率,當使用顆粒幹冰時,陷阱下降到-40華氏度左右。在此溫度下,諸如萜烯等高度易揮發的分子將與諸如丁烷等危險溶劑一起聚集在陷阱中。在高真空係統中,不斷降低的壓力會導致從陷阱中產生的產品損失,你保持這個陷阱的溫度越低,發生的情況就越少。幹冰可以在冷阱周圍使用,以保存萜烯和其他有價值的化合物。

    Dry ICE with IPA(isopropyl alcohol): Dry ice is extremely cold, but it’s hard to use dry ice to cool something else that cold. This is because the dry ice has limited surface area and air is a poor conductor of thermal energy. In order to increase the efficency and “cool” faster a liquid media such as Isopropyl alcohol or anti freeze can be used. Heat(thermal energy) is transferred through water almost 20 times faster than air making it especially good for heating or cooling. When using an isopropyl bath the cold trap can get down to -67 or below which is more than aduaquate to trap terpenes of all kinds. The trap is so cold that water will collect in significant quantities and freeze covering the surface area of the trap. The reduced surface area also reduces the traps overall efficiency.

    IPA幹冰(異丙醇):幹冰非常冷,但很難用幹冰來冷卻其他寒冷的東西。這是因為幹冰的表麵積有限,空氣是熱能的劣質導體。為了提高效率和“冷卻”更快,可以使用液體介質,如異丙醇或防凍劑。熱量(熱能)通過水傳遞的速度幾乎是空氣的20倍,這使得它特別適合加熱或冷卻。當使用異丙基浴時,冷阱可降至-67或以下,這比阿杜奎特更能捕獲各種萜類化合物。這個陷阱太冷了,所以水會大量聚集,並凍結在陷阱的表麵積上。減小的比表麵積也降低了陷阱的整體效率。

    Liquid Nitrogen: Liquid nitrogen is the ultimate extreme cold, boiling at -320.4°F Liquid Nitrogen is cold enough to Freeze gasses such as butane or propane. Nothing gets through a liquid Nitrogen cold trap because almost everything condenses at -300 degrees. Liquid nitrogen cold traps are used in ULTRA high vacuum applications in order to increase pumping efficency. Liquid Nitrogen is so cold that Liquid oxygen can form creating a potentially dangerous situations. Extra precautions must be taken in order to purge oxygen from the system in order to make it safe to use. Liquid Nitrogen is so cold that its used in ultra high vacuum applications to keep ALL contaminants from reaching the pumping system. It is also important to note the trap is so cold that water will collect in significant quantities and freeze covering the surface area of the trap. The reduced surface area also reduces the traps overall efficiency.

    液氮:液氮是極冷的,在-320.4度的溫度下沸騰,液氮的溫度足以凍結氣體,如丁烷或丙烷。沒有任何東西能通過液氮冷阱,因為幾乎所有的東西都在-300度時凝結。液氮冷阱用於超高真空,以提高抽運效率。液氮太冷了,液氧會形成潛在的危險環境。必須采取額外的預防措施,以便清除係統中的氧氣,使其安全使用。液氮是如此的冷,以至於它被用於超高真空應用,以防止所有汙染物到達抽吸係統。同樣重要的是要注意到陷阱是如此的寒冷,以至於水會聚集在重要的地方。
