Overview of the Leica VT1000 S Vibrating Blade Microtome



Welcome to New Life scientific My name is Steve. Today I'm going to be talking about the Leica VT 1000s vibrating microtone. We've sold several of these. This is one of our more complete units. We did have to do some work to make it complete. We wanted to show you those features with a lot of the other machines we see on the market are without them. And I had trouble finding images of how this thing works and looks. Most of them come with the magnifying glass. A lot of them aren't coming with the trapeze to hold the or knife blade. Once it's unscrewed, you can easily mount your blade in there. That Allen key will tighten that up into place. These are often not in the system when you get them. Also we see a lot of these without the tray. 

The sample tray probably best called a stage. This one also has the specimen mount. We did substitute a standard screw on this one. When you unscrew that screw, it releases the stage for removal. We had to manufacture this tool, which is basically it's a fancy Allen handle. Goes into a receiver. You push it down. It gives you the ability then to by turning the in the manual, it says you can place that opening any place you want on that stage, except where that screw is or where those ears are. Once you have that, it's able to be pulled up and you can release your sample. You adhere a sample onto your specimen disc that requires a particular glue, which is mentioned in the listing and in the manual. Just by putting that on there now. It holds well into place. 

You drop the unit into place. You drop the stage into place, the sample turn it to wherever you want it fastened, tighten the screw down. The stage is now locked into place. You can raise your magnet and now it releases. Install your blade unit's. 

Ready to rock. 

I did forget to mention this cavity is removable. There's a lever there. And that will come out. It can be lifted out when you don't have the blade in place. That's why that is a removable blade. And because it's removable, that's why it's often missing when we get them on the controls. You do can set the frequency of the vibration and the speed at which it advances the blade. Of course, you have your forward and reverse buttons and your up and down, which will raise and lower your stage. Once you've set your feed and frequency and everything that you want, you can press the start button and it'll go ahead and start. You can also do a continuous feed, which is the second push of the button. And then it will keep cutting that sample each time raising the sample up to meet the new cutting surface. Simple press of the button and it starts. 

You can see we have that set at a fairly high speed. When it's set at your lower speeds, you almost don't see it move. It'll come to the end, retract the blade and then raise the stage and start again. Each time it will be cutting a section, or I should say trim for you until you get into the place to the area that you want to save. Then you can be capturing your samples. There is an emergency stop, and so you can take a look at how well your cut is. You have the magnifying glass. 

There are light options available for these. This unit does not include one, but they are available on the market. You do have emergency stop over here. 

In case for some reason you needed to stop it right away, you can stop it. And that's the Leica VT 1000. In this particular case of what we're selling, it does include the tools to install the stage. And there you go. Thank you very much and stop back and see us again sometime. Bye.
