IITC 鉗式測(cè)痛儀是根據(jù) Randall-Selitto 理論設(shè)計(jì)是進(jìn)行炎癥足加壓實(shí)驗(yàn)的經(jīng)典儀器。
型號(hào)2450型
根據(jù) Randall-Selitto 法將藥物添加在小實(shí)驗(yàn)動(dòng)物的炎癥足上。Randall-Selitto 測(cè)痛儀測(cè)量單元具有壓力傳感器并通過(guò)液晶屏實(shí)時(shí)顯示測(cè)量參數(shù)。壓力施加器一端為彈性的尖形探頭另一端平坦。使用時(shí)將動(dòng)物足部放入壓力施加器中間對(duì)準(zhǔn)探頭施加壓力。逐步提高作用于動(dòng)物爪子上的機(jī)械壓力逼近動(dòng)物的疼痛閾限當(dāng)動(dòng)物出現(xiàn)縮足反應(yīng)時(shí)儀器自動(dòng)測(cè)量并記錄大壓力信號(hào)以g為單位。
與熱痛不同該儀器用于機(jī)械壓痛和鈍痛的痛覺(jué)測(cè)量常用于辨別左右爪不同的痛覺(jué)反應(yīng)。
鉗式測(cè)痛儀的產(chǎn)品特點(diǎn)
適用于大鼠和小鼠精確度為0.01克
大壓力400克數(shù)字顯示功能實(shí)時(shí)壓力、大值單位為g
配置腳踏控制器控制啟動(dòng)下次實(shí)驗(yàn)解放雙手提高實(shí)驗(yàn)效率可選的動(dòng)物固定支架可輕松固定動(dòng)物
方便操作測(cè)量誤差小于0.5%不需校準(zhǔn)采用RS-232輸出方式
鉗式測(cè)痛儀 Rodent Pincher Analgesia Meter
Rodent Pincher allows researchers to measure and test pain threshold in a simple, accurate method when measuring pain nociception.
The system can be used on mice or rats and will measure and display in grams the amount of force that has been applied to the animals paw.
Accuracy is .01 grams, no calibration needed.
One year warranty, CE certified
