Description:
<p>LaMotte Turbidity Standards 10.0 NTU (2020WE) are essential calibration solutions designed for precise turbidity measurement in water testing. These standards ensure accurate and reliable calibration for turbidity meters, supporting water quality professionals and educators in maintaining optimal water clarity testing.</p>
Description:
Estimate stream quality as it relates to solids in the water.<BR><BR>This Turbidity Tube is made from 1-<sup>3</sup>/<sub>4</sub>" (4.4 cm) clear polycarbonate tubing and is marked with easy to read black numbers on a white tape; tape is marked in centimeters. A drain tube with a crimp are supplied so the sample can be drained off until the Secchi pattern on the bottom just appears. The height of the water column is then recorded. Overall length of the tube is 24" (61 cm).<BR><BR>The optional Transparency Tube (item #67311-46) allow you to measure turbidity in streams where a secchi disk can't be used--simply fill the tube with water and look down. Each clear polycarbonate tube features a centimeter scale on one side and a secchi disk design, 2" (4.5 cm) in diameter, on the bottom. The secchi design is screwed to a rubber stopper that removes for cleaning. Drain the tube with the drain hose and attached finger crimp. Ideal for the GLOBE program!

Description:
The 1100RS Visible Spectrophotometer features an accurate 10nm bandpass model and is designed for use with <sup>1</sup>/<sub>2</sub>" (13 mm) round tubes or 10mm square cuvettes and is perfect for most laboratory/classroom applications. An adapter is supplied at no additional charge for 10 mm square optical glass cuvettes. The high quality silicon photodiode detector and 1200 lines/mm grating assures high performance. Auto zero function, one-touch blanking and built-in, automatic filters allow for easy operation. The large digital display allows for quick and easy readings. This visible spectrophotometer works with optional Windows® based software for easy data collection and application expansion to Standard Curve and Kinetics, Abs. and %T and Concentration, etc. Data can be easily exported to Microsoft Excel® for further processing and analysis. The software is designed for Windows based PCs using Windows® 2000, ME, or XP. A USB and RS-232 port is available on this spectrophotometer as well as Absorbance, Transmittance, Concentration (C) and Factor (F) modes. Each mode can be quickly selected with the touch of a button.

Description:
The Universal Specific Gravity Kit is designed to be used with any electronic scale with a minimum capacity of 15 grams and a tare (re-zeroing) function to easily measure the specific gravity of gemstones and minerals.<BR>Just weigh the stone "in air" on the integrated weighing platform of the scale, then without changing the setup, weigh the stone in water by placing it in the underwater weighing pan of the gem holder suspended above the platform. Plug the two values into the specific gravity equation and obtain the specific gravity of your stone.<BR><BR>Includes: lightweight gem holder support and underwater weighing pan, independent, spill-resistant, adjustable beaker support, beaker for filling with water - 100ml capacity, aluminum test weight, stainless steel tweezers, instructions, reproducible Specific Gravity worksheet, table of 300 common minerals/gems sorted by SG, with 6 other properties, including refractive index.<BR><BR><B>Note: shown with Boreal Balance - not included.</B>
