44401 Microscope Calibration Slide by Celestron

Ensure accurate readings from your microscope with the help of Celestron's Microscope Calibration Slide. Also known as a stage micrometer, the Celestron Microscope Calibration Slide is a standard 1" x 3" glass microscope slide that features an etched scale that is 1mm in total length and subdivided into 100 equal divisions.

The stage micrometer fits on your microscope's stage, allowing you to ensure your specimen measurements are correct. If you have a digital microscope and or a traditional microscope with a digital imager attachment, a stage micrometer is essential for calibrating the microscope's software settings. You can also use the stage micrometer to manually measure specimens that are 1/100th of a millimeter or larger, such as microfibers. If you have a non-digital microscope (e.g., Celestron Labs), you can use the stage micrometer to calibrate the microscope's eyepiece reticles and determine the field of view of different objective lens and eyepiece pairings. If you find yourself changing objectives and eyepiece reticles often, using your calibration slide regularly will help you maintain measuring accuracy.

Compatible Microscopes

The stage micrometer works with a wide range of Celestron microscopes and imagers to measure specimens or determine your microscope's field of view.

• Precise stage micrometer glass slide for calibrating your microscope's camera or imager
• 1mm ruler with 100 subdivisions to accurately measure specimens as small as 0.01mm
• Standard 1"x3" slide fits easily on a traditional microscope stage

BU5009-P Buffer, pH 9.00, 500mL by AquaPhoenix

• ± 0.02 at 25°C

pH Buffer should be used regularly, typically every day the meter is used to calibrate your pH meters. Pour buffer into a clean separate container and never return used or unused buffer back into the container. Always keep tightly capped and adhere to the expiration date which is printed on the label.

LSM Cap Kit, Tapped Cap & 1" PVC Fitting by Agrowtek

Two-part system for mounting SXL liquid level sensors from the top of a tank providing secure mounting, adjustable sensor heights, and easy installation and removal. Top mounting also avoids holes on the sides of the container to reduce chances of leaks.

Part 1: Cap Kit

Mount SXL optical liquid level sensors on the end of a 1" PVC pipe. Kit includes a tapped PVC cap with o-ring seal and PVC pipe fitting. Provide 1" schedule 40 or 80 PVC pipe to length.

Part 2: Flange Kit

Securely mount sensor pipes to the tank. Kit includes hardware and custom flange with locking set screw for clamping the pipe at the desired location. All stainless hardware is designed for easy service without tools after installation.

Flange can be removed from the tank by quickly removing the wing nuts. Studs remain bolted to the tank while the sensor can be pulled up and removed for cleaning and maintenance.
