三合一痛觉测痛系统包含electronic von frey,randall selitto,plethysmometer三套电子痛觉测痛仪,用三种方法完成对大鼠小鼠等动物的痛觉测量,欢迎来电咨询。


  • electronic von frey anesthesiometer 电子von frey测痛仪

  • randall selitto test paw pressure test meter 鼠爪压力测量仪

  • plethysmometer, paw volume meter or paw edema meter鼠爪肿胀测量仪


电子触觉阈疼痛阈测量仪机械痛阈测量仪von frey系统,简单易用。用来替代传统的von frey hairs纤毛机械刺激针von frey hairs.不仅可以von frey test测试机械痛阈或触觉阈测量,还可以测试疼痛阈值。它使研究者可以自动记录机械痛阈和触觉阈测量。操作简单,精确,设计紧凑。

电子von frey测痛仪的主要特点:

ø 适用mri探针

ø 单体内可插入三个探针

ø lcd 显示屏 (floating or last max. & minimum) 

ø 硬枪头能达 800 gr. 

ø “supertips™” 15 65gr. 

ø 适用1k探针

ø 电子微处理器0.1gr插入式探针

ø 可选的模拟输出线

ø 吸头可根据情况定制

ø 具有测量、存储和显示功能,免除了手算的繁琐。

ø 可以预设和选择最大限额,能精确到1g当到预设的限额时,警示灯会通知使用人员

ø 实验简便:选择合适的原件放在探针上,插进实验对象,根据实验对象的反应,仪器就能快速的显示出结果并储存。

ø 作为核心原件的内置传感器固定在元件上,并和电子系统相连,以便记录数据。所有的电子测痛仪已在出厂前校准完毕,不再需要购买任何的校准设备。

鼠爪压力测痛仪 randall&selitto测试,通过逐步提高作用于动物爪子上的机械压力,逼近动物的疼痛阈限,测量并记录动物产生逃避反应时的瞬间最大压力,以测定动物机械钝痛的痛觉阈限。



ø 适用于大鼠和小鼠

ø 精确度为0.1克,最大压力400

ø 数字显示功能

ø 配置脚踏控制器

ø rs-232输出




ø 无需润湿液,可消除由于重复浸入发生导电性的改变而产生的体积误差 

ø 配备90°角的全透明亚克力操作支架,可进行清晰方便

ø 维护方便,不需要特殊的护理液

ø 数据准确,不需要每次使用校准,每年仅需校正一次

ø 具有内置电源,实现停电不间断操作

ø 带lcd显示器,读书方便

ø 体积精确度:0.01ml(大鼠)0.001ml(小鼠)

order any one of the test systems complete and the only additional item(s) needed are the individual modules to perform each test.

electronics has up to three inputs allowing users to perform three very different tests with one electronic system when studies call for doing so.

all data is stored and displayed in the electronics supplied.

part# 2650 stand and sling sold separately



order any one of the 2390 series electronic von frey systems; add on either or both the digital paw pressure applicator only and/or the glass stand setup only and you have a system that is complete for all three individual tests.


a wonderful addition to any laboratory facility studying analgesic compounds in research.

stand and animal sling for randall selitto test sold separately.
