All buffers are guaranteed accurate to within +/- 0.01 pH units @ 25 deg C. Available sizes include pints(473mL), quarts(946mL) and gallons(3.786L). Buffer labels include pH vs. temperature information for precise calibration. Custom buffers are also available on an OEM basis. Please contact Sensorex regarding your requirements.

Electrode storage solution is available in pint and gallon sizes. This is the same solution that is shipped with all pH electrodes and ensures electrodes are ready for immediate use. Storage solution is recommended for long-term electrode storage since it is not color-coded and will not impart any color to the electrode's reference junction.

94306 PowerSeeker Accessory Kit by Celestron

• This economical seven-piece accessory kit enhances the performance of your Celestron PowerSeeker, or most any other telescope.
• Includes two full-size 1.25" eyepieces, three eyepiece filters, a cleaning cloth, and a case.
• One medium power & one high power eyepiece give you a new perspective on celestial objects.
• A Moon filter helps block out some moonlight so you can see more lunar detail, and the two color filters (Red & Blue) highlight features on Mars, Jupiter, and Saturn.
• A hard plastic carry case keeps everything safe in the foam-lined interior.

The Celestron PowerSeeker Accessory Kit is a great way to expand the enjoyment of your telescope. Inside the plastic, foam-lined carry case you'll find these accessories:

• 15 mm Kellner Eyepiece - 1.25"
• 9 mm Kellner Eyepiece - 1.25"
• #80A Blue Filter - 1.25"
• #25 Red Filter - 1.25"
• Moon Filter - 1.25"
• Microfiber Cleaning Cloth

Eyepieces - The 15 mm and 9 mm eyepieces can be used in any telescope with a 1.25" focuser. Each eyepiece is fully coated to improve light transmission and protect the optics. The 15 mm Kellner eyepiece offers a nice medium magnification view in most telescopes, and the 9 mm provides high magnifications, great for the Moon and planets, especially when seeing conditions are good.

Filters - Colored filters can be used to bring out certain details on a planet's surface or its cloud structure. Both planetary filters, as well as the Moon filter, can be used on any 1.25" eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.

• The #80A is a medium-blue filter that enhances the contrast of the cloud belts on Jupiter and the polar ice caps on Saturn. It also can be used to increase contrast on the Moon if you don't mind the color shift.
• The #25 filter is a deep red color and is a good choice when you want to define the polar ice caps on Mars. It's also fun to use this filter when observing Jupiter. The #25 Red filter blocks quite a bit of light coming through your telescope, however, so it is best used on bright objects with larger aperture telescopes.
• The Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it helps you see which phase she's in.

Cleaning Cloth & Case - Keep the microfiber cleaning cloth stashed in your PowerSeeker Accessory Kit case so that it will always be handy. It's better to use a microfiber cloth on your optics than wipes or tissue, as it will not leave a residue, and can be reused. Remember to blow or brush any dust particles off of your optics before rubbing them with the cloth.

The black plastic carry case has die-cut foam inside to protect and cushion your accessories. Keep each one in its appointed place when not in use and you ll keep them looking and performing like new.
