简单介绍:
美国Sutter公司微电极拉制器可分为垂直式拉制仪和水平式拉制仪 .垂直式的微电极拉制器是利用金属丝(钨丝或铂丝绕成螺管状)通过大电流使玻璃管加热到熔点,利用重力拉断.水平微电极拉制器则是利用弹力或电动力作单次或多次拉制.这后一种拉制仪可用于拉制胞内电极,通常是采用微处理器控制其拉制过程,也有用激光工艺进行拉制的,因而可以拉制石英玻璃管.
详情介绍:
微电极拉制器P-2000是美国sutter公司*新推出的高精度微电极拉制仪,主要特点是是可以拉制熔点很高的石英玻璃。由于石英玻璃有着优异的低噪声电学性能,同时电极坚硬,因此适合于脑片膜片钳记录.

特点:
 
P-2000微电极拉制器可编写100个拉制程序。拉制稳定,可靠的尖端小于0.03微米。
P-2000微电极拉制器P-2000微电极拉制器采用科学先进的方式拉制出玻璃、光纤、石英等材质的微电极。P-2000微电极拉制器与传统的拉制仪相比,P-2000微电极拉制器增加了CO2激光加热源,使之拥有更为强大的功能。
P-2000微电极拉制器可选用毛细管范围:*大外径:玻璃管:1.5mm石英管:1.8mm*小外经:玻璃管:0.125mm石英管:0.6mmP-2000微电极拉制器微电极尖端直径:5µm~10µm

玻璃微电极是膜片钳系统通过探头直接与细胞膜封接的部件,微电极主要是用不同的玻璃毛坯管,通过控制微电极拉制仪的温度,拉力,拉制时间等参数拉制而成.一般拉制仪可分为垂直式和水平式.垂直式的拉制仪是利用金属丝(钨丝或铂丝绕成螺管状)通过大电流使玻璃管加热到熔点,利用重力拉断.水平拉制仪则是利用弹力或电动力作单次或多次拉制.这后一种拉制仪可用于拉制胞内电极,通常是采用微处理器控制其拉制过程,也有用激光工艺进行拉制的,因而可以拉制石英玻璃管.

美国Sutter公司的P-2000激光微电极拉制仪适用于各种玻璃微电极,特别是石英微电极的拉制制作,作为在电生理及电化学实验中常用的石英,硅硼及其它玻璃微电极,P-2000均可拉制。其拉制的电极尖端*小可达0.03um。而且其拉制的电极重复性非常好。因此在电生理,电化学等方面被广泛使用。.

性能指标: 
                    
1. 可用于拉制石英,硅硼及其它玻璃 微电极。
2. 全部微电脑自动控制
3. 写保护锁和日期封印
4. 每次拉制都产生两个对称的电极
5. 仪器内部的CO2分子激光器可正常工作十年以上。
6. 优化的速度检测回路有*大的敏感度和重复性
7. 能拉制稳定、可靠的尖端小于0.03微米的电极
8. 拉制温度不拉受限制。可满足多种 需求。
9. 质量控制:电镜检测电极尖端变化小于0.1微米,一般大约为0.06微米
