The Edgewood Chemical Biological Laboratory (ECBC) recently acquired a new machine that improves the efficiency and safety in processing orders of dilute chemical agents used for research and testing.
埃奇伍德化學(xué)生物實(shí)驗(yàn)室（ECBC）最近獲得了一種新機(jī)器，可以提高用于研究和測(cè)試的稀釋化學(xué)制劑處理訂單的效率和安全性。
 
Brandon Bruey, chemist at ECBC’s Chemical Transfer Facility (CTF), said the dilute samples contain a high-purity sample of chemical agent dissolved in solvent that has been analyzed and certified so that other research labs know what concentration with which they are working.
ECBC化學(xué)轉(zhuǎn)移設(shè)施（CTF）的化學(xué)家布蘭登·布魯伊（Brandon Bruey）說，稀釋樣品中含有溶解在溶劑中的高純度化學(xué)試劑樣品，這些樣品已經(jīng)過分析和認(rèn)證，以便其他研究實(shí)驗(yàn)室知道它們的工作濃度。
 
He added that most customers utilize the dilute agent solutions as standards to ensure they can identify and quantify chemical agent material on analytical instrumentation.
他補(bǔ)充說，大多數(shù)客戶使用稀釋劑溶液作為標(biāo)準(zhǔn)，以確保他們能夠識(shí)別和量化分析儀器上的化學(xué)試劑材料。
 
After dilute solutions are certified by ECBC, they must be injected into open-ended glass ampules, which are heat-sealed closed for safe transport and handling. Until recently, each ampule had to be sealed using a hand torch and glass rod, which, according to Bruey, was a time-consuming and labor intensive process.
稀釋溶液經(jīng)ECBC認(rèn)證后，必須注入開放式玻璃安瓿中，瓶口玻璃瓶蓋應(yīng)熱封，以確保安全運(yùn)輸和搬運(yùn)。直到最近，每個(gè)安瓿都必須用火焰噴槍和玻璃棒密封，據(jù)布魯伊說，這是一個(gè)耗時(shí)費(fèi)力的過程。
 
ECBC’s CTF will now use a new bench-scale ampule sealer that automatically closes each vial. First, the ampules are loaded onto a circular carousel, which individually pass in front of a fixed torch. The machine then evenly melts glass seals without the issues seen with hand- sealing, such as glass bubbles or leaky vials.
ECBC的CTF現(xiàn)在將使用一種新的臺(tái)式安瓿封口機(jī)，自動(dòng)熔封每個(gè)小瓶。首先，安瓿被裝載到一個(gè)圓形樣品載具上，旋轉(zhuǎn)載具盤在一個(gè)固定的火焰噴頭前面輪換傳遞小瓶。然后機(jī)器均勻地熔化玻璃密封件，而不會(huì)出現(xiàn)手工密封時(shí)出現(xiàn)的問題，例如玻璃氣泡或玻璃瓶泄漏。
 
“This gives every one of our vials a uniform seal and speeds up the process immensely,” Bruey said.
布魯伊說：“這使我們的每一個(gè)小瓶都有一個(gè)統(tǒng)一的密封，大大加快了這個(gè)過程。”。
 
According to ECBC, the new machine provides consistent heating with a gas mixture of oxygen and propane that is control to ensure the best flame temperature.
根據(jù)ECBC的說法，這臺(tái)新機(jī)器提供持續(xù)加熱的氧氣和丙烷混合氣體，這是控制，以確保最佳火焰溫度。
 
“Once the flame temperature and weld times are set, the ampule sealer will produce a more uniform seal for all ampules,” Bruey said. “It takes human error out of the equation.”
布魯伊說：“一旦火焰溫度和焊接時(shí)間設(shè)定好，安瓿封口機(jī)將為所有安瓿生產(chǎn)更均勻的密封。”。“它將人為錯(cuò)誤排除在等式之外。”
 
While the machine does ensure a safer process, it still takes a team of four to complete a production run — one to fill ampules, one to operate the ampule sealer, one to ensure vials are fully sealed, and one to correctly label each ampule.
雖然這臺(tái)機(jī)器確實(shí)確保了一個(gè)更安全的過程，但仍然需要一個(gè)四人小組來完成生產(chǎn)運(yùn)行——一個(gè)負(fù)責(zé)灌裝安瓿，一個(gè)操作安瓿封口機(jī)，一個(gè)確保小瓶完全密封，一個(gè)負(fù)責(zé)正確標(biāo)記每個(gè)安瓿。
