The Eppendorf Combitips have been completely redesigned and optimized to meet the increased requirements of a modern laboratory to a greater extent than ever before. The result is the Combitips advanced®. As they offer a wide variety of advantages in comparison with the Combitips plus, we talk about the 360° Evolution! Features Combitips advanced are the ideal system components for all Eppendorf Repeaters The 9 volume sizes (0.1 mL–50 mL) offer a maximum range of dispensing volumes with increments as low as 100 nanoliters depending on the Combitip used Elongated Combitips in volumes 2.5 mL, 5.0 mL and 10 mL make it possible to reach the bottom of the most common laboratory vessels An individual color coding facilitates the quick identification of the desired Combitips The unique funnel geometry ensures comfortable handling while preventing damage to gloves Combitips advanced are offered in 5 different purity grades to support a range of applications The appropriate purity grade for each application: Eppendorf Quality™, Sterile, PCR Clean, Forensic DNA Grade or Biopur® Applications Positive displacement principle (comparable to a syringe) High-precision dispensing regardless of the physical properties of the liquid (e.g., viscosity, volatility, density, temperature...) Prevents aerosol contamination with hermetically sealed piston for secure dispensing Provides protection from radioactive and toxic substances Quick dispensing of long series with precise, repeated dispensing of identical volumes (with Repeater hand dispensers) Assortment Pack 1 of each of the 9 tip volumes and one adapter for the 25 and 50 mL tips

Ammonia CHEMets® Refill, 0-1 & 1-10 ppm
Item #:

CHEMetrics Part No. R-1501
Low-level ammonia nitrogen may be naturally present in water as a result of the biological decay of plant and animal matter. Higher concentrations in surface waters can indicate contamination from waste treatment facilities, raw sewage, industrial effluents (particularly from petroleum refineries), or fertilizer runoff. Excessive ammonia concentrations are toxic to aquatic life. The Direct Nesslerization Method Reference: ASTM D 1426-08, Ammonia Nitrogen in Water, Test Method A. APHA Standard Methods, 18th ed., Method 4500-NH3 C - 1988. The test kits employing the well-established Nessler reagent* to determine ammonia concentrations are applicable to drinking water, clean surface water, good-quality nitrified wastewater effluent, and seawater. In some waters, calcium and magnesium concentrations can cause cloudiness of the reagent. Adding a few drops of stabilizer solution (Rochelle Salt) will prevent this cloudiness. References recommend distilling samples prior to analysis. Results are expressed as ppm (mg/L) ammonia-nitrogen, NH3-N. Shelf-life: although the Nessler reagent is stable, its high alkali content attacks the glass ampoule. The resulting precipitate interferes with color comparison. We recommend stocking quantities of CHEMets® and VACUettes® ampoules that will be used within five months. A two-month supply of Vacu-vials ampoules is suggested. Refrigeration will dramatically extend the shelf-life of these products. Kit comes in a plastic case and contains everything needed to perform 30 tests: Refill, Low and High Range Comparators, Stabilizer Solutions, 25 mL sample cup, 1.0 mL syringe, and instructions.
