93431 Luminos 10mm Eyepiece by Celestron

The Luminos series eyepieces offer a wide 82° field of view in both high power and low power models, allowing you to make the most of your telescope, whether you own a short, fast refractor or a Celestron EdgeHD telescope. The optical set consists of six or seven elements (depending on the model) and is fully multi-coated for crisp, sharp views. All six Luminos eyepieces are parfocal, which means you can switch out eyepieces during observing sessions with little or no additional focusing required.

The Luminos eyepiece body is made of polished and anodized aluminum. A rubber grip runs around the equator of the eyepiece, giving you a secure grip and an easy method for raising and lowering the retractable eyecup. Simply twist the rubber grip to adjust the height of the eyecup. The insert barrel is threaded to accept filters.

• Enjoy wide 82° views with Celestron Luminos Eyepieces.
• Retractable eyecup pops up when you need it, drops down when you don't.
• Sturdy anodized aluminum barrels are threaded for filters.
• A rubber grip keeps the eyepiece securely in your hands, even when it's cold or you have gloves on.
• Other eyepieces in the Celestron Luminos Series include: 7mm - 1.25", 15mm - 1.25", 19mm - 2", 23mm - 2", 31mm - 2"

93529 X-Cel LX 1.25" 2x Barlow Lens by Celestron

When inserted between the eyepiece and telescope, this X-Cel 2X Barlow lens doubles the magnification of all your 1.25" eyepieces. The premium apochromatic optics yield high contrast, sharp images, virtually free of false color.

The black anodized housing with orange highlights matches the eyepieces in the Celestron X-Cel LX line. A centralized rubber grip helps to keep your hands securely on the barrel, even when your fingers are cold or you are wearing gloves. A brass compression ring just inside the top of the X-Cel Barlow grabs your eyepiece gently but firmly when you turn the thumbscrew. Once the thumbscrew has been secured in place, the brass ring keeps your eyepiece in the Barlow instead of relying on the tip of the thumbscrew itself, offering a better grip and protecting the barrel from scratches.

The barrel of the Celestron X-Cel LX 2x Barlow is threaded to accept 1.25" filters, allowing you to change eyepieces without removing and re-attaching the filter from each eyepiece barrel.

• Quality X-Cel LX 2x Barlow doubles the magnification of any 1.25" eyepiece.
• 3-element apochromatic, fully multi-coated optics offer up bright, sharp images.
• A rubber grip helps to avoid accidental drops
• Barrel is threaded to accept standard 1.25" filters.
• A brass compression ring holds the eyepiece firmly in place.

AI3109 LabSen 831 Glass-body pH Electrode for Strong Acid Samples and HF (Hydrofluoric) Acid by Apera

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 831 HF pH Electrode is designed for professional pH measurement of solutions containing HF (Hydrofluoric) acid, and other strong acidic solutions.

LabSen HF glass membrane - designed for accurate measurement in strong acid samples, and is resistant to hydrofluoric corrosion, good for 1000 times of measurement (measurement time<1 minute, and HF concentration should be less than 0.1mol/L or 0.2% wt%)

Built tough - The hemispherical glass membrane is 10 times stronger than traditional glass membranes, and highly resistant to general impact, saving the electrode from accidental damage.

Silver Ion Trap Reference System - On top of the Long-Life reference system, a silver ion trap is added to further prevent junction clogs.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera MP500) to enable ATC or manually input temperature to realize temperature compensation.

• Proprietary pH sensor technology and premium materials from Switzerland
• LabSen HF glass membrane designed for accurate measurement in strong acid samples, and is resistant to hydrofluoric corrosion
• Silver Ion Trap Reference System
• LabSen's sturdy glass membrane is 10 times stronger than traditional glass membranes
