The 900A is designed to measure hydrostatic pressure in small vessels and cells. Pressure ranges of -200 to +400 millimeters of mercury can be measured with stability and accuracy. The system's sensing element is an electrolyte-filled glass microelectrode with a tip diameter range of 2 to 5 microns. Pressures of electrolyte solutions are measured by maintaining a salt concentration gradient at the tip of the sensing electrode in dynamic equilibrium by applying an equal air pressure inside the microelectrode. The pressure reading appears on the front panel display and via the BNC recorder output. Because the piezo electric pressure controller uses external pressure and vacuum sources, pressures lower than -200 to greater than +400 mm Hg can be quickly and accurately measured at the microelectrode tip.

The PSMB5N Surgical Microscope has a motorized focusing system that allows for hands free operation. It is lightweight, compact and easy to maneuver. Dual bulbs prevent illumination failure during surgery. It has an optional video adapter and five magnification steps. This video shows you how to assemble your microscope.
Safety is a primary concern when setting up equipment. Here are a few pointers.
- This setup requires open space to work in.
- Be sure to remove the packing materials as soon as you unpack your boxes.
- Watch your hands when you are using a box cutter.
- The articulating arm is spring loaded. Be sure to release the tension on it in a controlled manner.
- Be sure to remove all parts from the boxes before you throw the...more
