簡介(jie)


Q-Box AQUA采用(yong)間歇(xie)流動呼吸(xi)法,測(ce)量水生動物(脊(ji)椎(chui)動(dong)物和無脊椎動物(wu)均(jun)可)的(de)代謝(xie)速率。即(ji)將水生(sheng)動物放置在一個呼(hu)吸室(shi)中,通(tong)過(guo)溶解氧的減(jian)少(shao)來(lai)衡(heng)量代(dai)謝速(su)率(lv)。耗氧率(VO2)通過軟件(jian)進(jin)行(xing)計(ji)算,原始(shi)溶(rong)解氧數據經(jing)鹽(yan)度(du)、溫(wen)度(du)和壓力校正(zheng),計算(suan)結(jie)果(guo)顯示並保(bao)存在(zai)軟件中(zhong)。

優(you)點(dian)


l 間(jian)歇流動呼吸法(fa)無(wu)需將(jiang)動物從(cong)試驗(yan)箱(xiang)中取(qu)出,測量依(yi)次(ci)進行,兩次測量(liang)之間用淡水衝(chong)洗試(shi)     驗(yan)箱,避(bi)免(mian)了傳(chuan)統(tong)   密(mi)閉式(shi)測量方法導致的呼吸時內產生缺氧狀(zhuang)態。

l 數(shu)據(ju)準(zhun)確(que),讀(du)數穩定,維護簡(jian)單(dan);·

l 能長(zhang)期(qi)地(di)自動測量;·

l 有(you)不同(tong)大小(xiao)呼吸室可以(yi)選擇(ze),適(shi)宜(yi)於(yu)各種體積(ji)的水生動物測量

l 所(suo)有部(bu)件統一(yi)安(an)裝在堅(jian)固(gu)的運(yun)輸箱中,便於攜(xie)帶和存(cun)放。




測量方(fang)式


在實驗過程(cheng)中,水通過液流泵在動物室和帶(dai)光學(xue)溶解(jie)氧(yang)探針(zhen)的流通容(rong)器(qi)中循環。由(you)數字(zi)控(kong)製單元(yuan)(DCU)控製(zhi)三(san)通閥(fa),軟(ruan)件控製設定(ding)係(xi)統的循(xun)環(huan)或(huo)衝洗(xi)模(mo)式。

在循環模式下進行呼吸測量,在衝洗模式下用水(shui)浴中的含(han)氧水衝洗動物室。循環-衝洗-循環,重(zhong)複(fu)運行,直到(dao)實驗結束。衝洗和循環階(jie)段的時(shi)間由用戶(hu)在軟件中選(xuan)擇。

用於小樣(yang)本(ben)的mini-AQUA


對(dui)於小型(xing)魚類和昆蟲幼蟲(chong)(~1g)的水生呼吸測量,Qubit提(ti)供(gong)了mini-AQUA套(tao)裝(zhuang)。改(gai)良(liang)版的Q-Box Aqua帶有小型水生呼吸室(9ml)和(he)用於更(geng)小係統體(ti)積的組件。還包括一個微(wei)型室(體積為(wei)1.23ml),用於測量小於0.5g的幼(you)蟲、卵(luan)和幼魚(yu)等非(fei)常(chang)小的樣品的耗(hao)氧率VO2。在測量期間,微型室采用間歇停(ting)止(zhi)流(liu)動模式,並(bing)將溶解氧探針直接(jie)放(fang)置在該(gai)室中,從而(er)提高係統的靈(ling)敏(min)度和分(fen)辨(bian)率。

客(ke)戶評(ping)價(jia)


“We have been using the Q-Box AQUA respirometry package for a year and have been impressed with the quality and versatility of the system. Although designed for teaching, we have found it to be more than adequate for basic research applications on both fish and cephalopods. The mechanical systems are well designed and easily serviced and the software is intuitive and flexible enough for use in diverse applications. The technicians at Qubit are outstanding; they were able to modify the system to suit our particular needs and they have always been quick to respond when technical support was required. The fact that Qubit ships the system in a protective case was also a big plus for field work!”
