Re: Four videos of Proper Techniques for Permanent Slide Making of Whole Mount Insects

To Charles: Your post did not mention your location, but in the USA ( where I live) you can purchase Xylene in large 3.8L (1 gallon) containers advertised as a "stronger than paint thinner" solvent from large hardware stores. As I stated in the video, Xylene is a known toxic solvent so I use an acti...

Four videos of Proper Techniques for Permanent Slide Making of Whole Mount Insects

This is my second attempt at creating a "How to" video to demonstrate the proper technique for permanent slide preparation of whole mount insects. I created four ten minute videos. Technical difficulties with my IPhone prevented a smooth presentation but I think I got the important information acros...

Re: Dating a vintage microscope?

This microscope was manufactured in Japan circa 1960. The Japanese microscope manufacturer, the name has escaped me at the moment, produced several inexpensive amateur models that were all standard, with little variation but branded to appear made by different manufactureres. An example of the above...

My collection, continued

Since I exceeded the amount of pictures I could post I thought a second posting would do. The 1500x at twice the price was considered a semi-pro microscope, having better optics than either the 900x or 1200x The 900x only had three eyepieces (5x,10x and 15x) to the 1200x with four eyepieces (5x,10x,...
