震盪組織切片機

產品型號: Model 7000smz-2
廠牌名稱:
7000smz-2型震盪組織切片機為Campden Instruments 生產最高階的震盪切片設備,目前世界上最頂尖的神經科學研究中心皆有這部切片機的身影,相較於基本款的5100型,7000型擁有更高的震盪頻率、更有彈性的刀片控制、以及更強大的自動排程切片功能,大大降低切片造成的人為誤差。5100型中為選配功能的Z軸偏差校正功能於7000型中為標準配備,此外您可選配2倍放大鏡與冷光光源搭配使用。

產品特點

Our top of the range high precision, vibrating microtome (vibrotome for short), this is the finest tissue slicer in the world for preparations for visual patch clamping or high resolution imaging. The 7000smz series Vibrating microtome has been the instrument of choice for many labs for 10 years - over 450 labs and counting!

Using our microtomes, research detailing sectioning for visual patching of neurological tissue, heart, lung, and tissue scaffolds have all been published. The 7000smz-2 microtome represents significant advances with higher precision at a lower cost.

The vibrating mechanism of the 7000smz-2 microtome delivers unprecedented accuracy with nearly silent operation. Every machine is tested before dispatch by our in-house measurement devices and each machine is supplied with its own z-axis calibration checker.

The effect of excessive Z-axis deflection on the health and viability of the tissue preparation has been much discussed since the publication of Geiger et al (2003) and the Campden 7000smz-2 tissue slicer, with ≤ 1µm Z-axis deflection across a wide range of vibration speeds and amplitudes, delivers healthy viable sections every time.

The user interface is easy and versatile (with no foot switch unlike previous models) and offers simple operation at the push of a button or a range of changeable parameters for the expert user. The Campden 7000smz-2 also provides longevity of performance, as not only does the slicer give ≤ 1 µm performance out of the box, but the advance vibrating mechanism does not contain bearings and other elements subject to wear. Thus it will retain the ≤ 1 µm z-ad performance for years to come, giving you consistency in your biological preparation, without the need for expensive servicing.

Holding the tissue close to 4° C must continue throughout the slicing procedure. This can be done with passive cooling where a known amount of ice is used to maintain the cooled a.c.s.f. or with an electronically controlled thermo-electric Tissue Bath Cooler (7610A).

We have developed both ceramic and stainless steel microtome blades, alongside the machine, so that the grinding and honing facets for the blade edge are matched to the blade downward angle of orientation to the tissue. The ceramic blades have a particular advantage when slicing brain tissue older than 30 days. These ceramic microtome blades also have a second advantage in that unlike stainless blades, these do not have to be replaced after each tissue sample.

Other options include an LED cold light and magnifier or scope for clear observation whilst slicing. Shown with optional Slice incubation chamber and temperature controller.

Highlighted Accessory: Tissue Slice Recovery Chamber

Shown alongside the tissue slicer above, the Model 7470 Temperature-controlled Slice Holding Chamber was developed as an optional accessory to the Campden Instruments range of tissue slicers. They are designed to hold and maintain tissue slices in six sub-chambers at physiological temperatures with an aeration supply to allow recovery from slicing as well as incubation during the experimental day.
