885450 ——Homogenisers, DUALL 和 885500——Potter-Elvehjem with All-Glass的区别  
二者都能连接马达使用，玻璃管都有磨砂内面。
885450有两种杵，1、玻璃材质结构的杵适合匀浆肌肉、心脏、肺；PTFE材质结构的适合肺和脑的匀浆。885500是也有两种杵，玻璃杵适合结缔组织，PTFE杵适合软组织（soft tissues)。
885450研磨面比885500大，所以研磨效率更高；

杵与圆锥和圆柱表面紧密地配合使组织减少产生一个均匀的匀浆。使用此装置使磨削效率大大提高。

·  圆形玻璃结构处理结缔组织，比如肌肉、心脏和肺，很理想。

·  机构很坚固足以承受杵被电机马达驱动。

·  杵被设计能与货号788000的适配器配合使用。

·  所有组件单独可购买，并且完全可以互换。

·  杵和管之间的间隙是0.004英寸,0.006英寸。

·  由膨胀系数33的低溶出硼硅玻璃制成。符合USP type I标准和ASTM E438, type I标准，A级。

Combines both conical ａnd cylindrical surfaces to effectively reduce tissue ａnd produce a uniform homogenate. Grinding efficiency is greatly improved when this tube is used.

· This ground glass model is ideal for connective tissue such as muscle, heart ａnd lung

· Construction is strong enough to allow the pestle to be motor-driven

· Pestles are designed to be used with 788000 stirrer adapters

· Replacement components are available ａnd completely interchangeable

· Clearance between pestles ａnd tubes is 0.004” to 0.006”

· Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I ａnd ASTM E438,
Type I, Class A requirements
