IITC 鉗式測痛儀是根據(jù) Randall-Selitto 理論設(shè)計是進行炎癥足加壓實驗的經(jīng)典儀器。

型號2450型

根據(jù) Randall-Selitto 法將藥物添加在小實驗動物的炎癥足上。Randall-Selitto 測痛儀測量單元具有壓力傳感器并通過液晶屏實時顯示測量參數(shù)。壓力施加器一端為彈性的尖形探頭另一端平坦。使用時將動物足部放入壓力施加器中間對準探頭施加壓力。逐步提高作用于動物爪子上的機械壓力逼近動物的疼痛閾限當動物出現(xiàn)縮足反應(yīng)時儀器自動測量并記錄大壓力信號以g為單位。

與熱痛不同該儀器用于機械壓痛和鈍痛的痛覺測量常用于辨別左右爪不同的痛覺反應(yīng)。

鉗式測痛儀的產(chǎn)品特點

大壓力400克數(shù)字顯示功能實時壓力、大值單位為g
配置腳踏控制器控制啟動下次實驗解放雙手提高實驗效率可選的動物固定支架可輕松固定動物
方便操作測量誤差小于0.5%不需校準采用RS-232輸出方式

鉗式測痛儀 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
