• 可透過連接電腦輸出數據成純文字文件與Excel數據表格

拉力測試儀主要用於測量大、小鼠前肢抓力，評估藥物、毒素、肌肉鬆弛劑、疾病、衰老及神經損傷等對肌肉力量的影響。將受試動物置於實驗臺上，頭前方為裝有力感測器的抓杆，抓杆高度可調。 當實驗人員拖動動物的尾巴時，該動物會為了阻止非本意的向後運動而本能的抓住前方的抓杆，直到實驗人員的拉力超過它的最大抓力。當動物鬆開抓杆時，儀器會自動記錄最大力值，並顯示在液晶屏上。

此外，通過可選附件網狀抓杆，可用於測量四肢或後肢的抓力。設備配備軟體，方便紀錄實驗資料。

The Ugo Basile Grip-Strength Meter automatically measures grip-strength (i.e. peak force and time resistance) of forelimbs and - via the optional grid - hindlimbs in rats and mice. The effects of drugs, toxins, muscle relaxants, disease, ageing or neural damage on muscle strength may be assessed.

The Grip Strength test is a perfect complement to the gold standard Ugo Basile Rota-Rod device for motor coordination and motor function experiments. The effects of drugs, toxins, muscle relaxants, disease, ageing or neural damage on muscle strength may be assessed.

Our device is sold with full optional, including all available grasping tools and grasping grids, and the software.

The animal is placed over a base plate, in front of a grasping bar (either T-shaped or trapeze-shaped, or the optinoal grid), whose height is adjustable. The grasping tool is fitted to a force sensor connected to the Peak Amplifier, which guarantees a reliable and automated detection of the animal response. The force transducer has a maximum applicable force of 1500g, with a resolution 0.1g.

The device can be used as a standalone or connected to a PC via the USB port, for monitoring and data recording: in fact, our GSM comes standard with both a control unit with internal memory where a number of data can be saved, and the new DCA software for signal monitoring, data transfer and analysis. Once saved, data can be browsed on the control unit and/or trasferred to a PC in proprietary , plus Excel (.xlps) or text (.txt) format, to be managed by most statistical analysis packages available on the market.

The Ratemeter (controller) and Slope (software) features, help the researcher to verify that the desired force is applied at a consistent rate. 

The transducer incorporates a proprietary memory chip to store all calibration parameters, so that no calibration is required for normal use; moreover, the controller will prompt to auto-zeroing routine at every measurement to automatically adjust any offset.

In alternative to the standard plastic grasping grids, a metal grid 13x11cm is also available as optional, Cat. No. 47200-327.

When pulled by the tail, rodents instinctively grab anything they can, to try to stop this involuntary backward movement, until the pulling force overcomes their grip strength. when positioned in front of the GSM bar, or trapeze, or grid, the animal grasps at it.

After the animal loses its grip on the grasping bar, the peak amplifier automatically records and stores the peak pull-force achieved by the limbs and shows it on the display.
