IITC 鉗式測痛儀是根據 Randall-Selitto 理論設計，是進行炎癥足加壓實驗的經典儀器。
型號2450型
根據 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。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，當動物出現縮足反應時，儀器自動測量并記錄壓力信號，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。
鉗式測痛儀的產品特點
適用于大鼠和小鼠精確度為0.01克
壓力400克數字顯示功能，實時壓力、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
