LabSen 331 POM-body pH Electrode for Wastewater Treatment by Apera

Backed by proprietary Swiss sensor technology and materials, the LabSen® 331 POM Combination pH Electrode is designed for testing wastewater, emulsion, suspension, and samples containing protein and sulfide.

LabSen unique blue hemispherical glass membrane - faster response time, better repeatability, and built tough, highly resistant to general impact (totally differentiates from the traditional fragile glass bulb membrane).

Polymer Electrolyte - The solid polymer electrolyte is in direct contact with test samples. The anti-pressure capacity can reach up to 6 bars, making it ideal for testing suspension and wastewater. No more frustrating clogged junctions.

Long-Life Reference System - The LabSen 331 pH electrode adopts a long-life reference system, which is composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of reference electrode and extends the service life of the electrode.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors, such as Apera Instruments MP511, PH850, PH8500, PH700, PH910, PH950, PH820 and PC820. The temperature sensor is not built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to realize temperature compensation.

The electrode is backed up with a 6-month warranty by Apera Instruments.

• Proprietary pH sensor technology and materials from Switzerland
• Unique LabSen® blue glass membrane, faster response rate, better repeatability, and impact-resistant
• Polymer Electrolyte, ideal for testing wastewater and suspension. No more clogged junction
• Long-Life Reference System, improving the stability of reference electrode and prolong the service life of the electrode
• POM housing, highly resistant to corrosions

K-1520A Ammonia HR CHEMets® Test Kit (25-250 ppm) by AquaPhoenix

The K-1520A Ammonia HR CHEMets® Test Kit (25-250 ppm) comes in a plastic case and contains everything needed to perform 30 tests (except distilled water): 30 HR CHEMets® ampoules, a color comparator, 1.0 mL syringe, 25 mL sample cup, and instructions.

Shelf life: Although the Nessler reagent is stable, its high alkali content attacks the glass ampoule. The resulting precipitate interferes with color comparison. The refill has a 5-month shelf life when stored in the dark and at room temperature. This shelf life can be extended by 18 months if the refill is refrigerated.

93420 X-Cel LX 2.3mm Eyepiece by Celestron

Celestron X-Cel LX series eyepieces offer a 60° apparent field of view, perfect for the Moon, the planets, and a plethora of deep-sky objects. The premium six-element optical set is finished with multiple layers of high-transmission coatings for clear, sharp images. The edges of the optics are blackened for increased contrast. All seven X-Cel LX eyepieces sport 16 mm of comfortable eye relief, and are parfocal, which means you can switch out eyepieces within the series during observing sessions and little or no additional focusing will be required.

The X-Cel LX eyepiece body is made of black-anodized aluminum. The pop-up eyecups make it easy to adjust the height for different users. Turn them in one direction to extend the length, and the other direction to provide a flat surface, preferable to most eyeglass wearers. A treaded rubber grip around the center of the eyepiece barrel offers secure handling, even in moist conditions or with heavy gloves on. The 1.25" insert barrel is threaded to accept filters.

• X-Cel LX eyepieces, optimized for planetary viewing, offer a 60° field of view through a six-element fully multi-coated lens system.
