Vernier scales can be used on microscopes, stereotaxic frames and micromanipulators. The vernier scale was invented by French mathematician Pierre Vernier in 1631 as an upgrade on Pedro Nunes' measurement system for precision astrolobes. With a main scale and a sliding secondary scale, a vernier is used for making precise measurements. 

How a Vernier Scale Works

The vernier scale is marked with divisions slightly smaller than the divisions of the main scale. For example, a vernier scale could have 11 markings for every 10 on the main scale. That's 10 divisions on the vernier scale for every 9 on the main scale. This means that the vernier divisions are each 90% of the main scale divisions. In this case, the 0-line and the 10-line...more

Gas anesthesia with Isoflurane is quickly becoming the standard method of general anesthesia for rats and mice in biomedical research. The advantages of using gas anesthesia for in-vivo examinations include:

• Fewer complications than injectable agents
• Allows for longer exam duration
• Easier administration and control
• Readily incorporated into existing procedures
• Level plane of anesthesia
• Minimal animal handling/Less stress
• No controlled substances required
• Quick recovery time
• Economical and versatile

These are designed to tightly and flexibly fit on various size rodents. The optically clear masks are designed to provide access to the eyes and head of the rodent. These masks provide stability of the animal for examinations and surgery. And, they may be trimmed for custom applications...more

You can use the PZMIV stereo microscope with a stereotaxic frame as shown in the image below. This setup shows a PZMIV-BS. The U-frame Base Plate (502045) is shown, but most stereotaxic frames can be used in this way. Choose a stereo microscope objective that allows you plenty of room to work. For example, the 0.5X objective has 187mm working distance, or the 0.32X objective has 296mm working distance. You could also add a Z-LITE-Z186 illuminator. If necessary, use a 5 to 10 lb.counter weight on the boom stand base to prevent the microscope from tipping.
