These options ensure a more modern and smarter student experience, increasing accuracy and efficiency. Other Standard Features and Equipment Transport lock, stainless steel weighing pan, menu and adjustment lockout switch, software and mechanical overload/underload protection, stability indicator, auto tare, low battery indicator, auto power off user selectable print options and communication settings. Applications Weighing: allows you to calculate the weight of the samples in the selected unit of measure. Density determination: calculation of the density of solids or liquids. With the built-in weigh below hook, you can test for the specific gravity of objects that cannot be placed on the weighing pan. Molar Concentration: Calculate the mass of a sample and automatically convert to the molar concentration. MODELS AVAILABLE: Applications Weighing, determination of density, weighing of moles Screen Liquid crystal display (LCD) with backlight Operation AC adapter (included) or 4 AA batteries (not included) Communication RS232, USB host, USB device, Ethernet or Bluetooth™ (available as an accessory) Construction ABS housing, stainless steel bowl, ABS draft shield (1 mg model only), bottom weigh hook, transport lock, manual calibration lock switch, security slot Project features Stability indicator, stackable design with storage lid included (excluding 1 mg model), mechanical and software over/underload protection, low battery indicator, auto power off, auto tare, span calibration mass included in models with capacity up to 620 g NO MORE BROKEN SCALES! The excellent overload protection of the Scout balance consists of a weighing pan made of high-strength stainless steel and a pan support made of impact-resistant plastic. The system allows the balance to safely support loads up to 10 times its rated capacity, withstanding use in even the most demanding educational environments. In addition, the integrated transport lock protects the load cell from damage during transport, stacking and storage.

The Waters 2487 Dual Absorbance Detector is a two-channel, tunable, ultraviolet/visible detector des (more)igned for high-performance liquid chromatography applications. The detector uses newly designed optics with an enhanced illumination system for improved performance. These design features increase the optical throughput and sensitivity, and reduce bandwidth. This results in an overall increase in signal-to-noise ratio and improved linearity. The Waters 2487 Dual λ Absorbance Detector has the following capabilities: Stand-alone programmability – Stores up to 10 user-defined programs (or methods) consisting of up to 16 programmable timed events and 2 threshold events each. Single or dual wavelength – Monitors absorbance at one or two discrete wavelengths. Wavelength verification reference – Ensures wavelength accuracy. Automatic second order filter – Automatically engaged for wavelengths 370 nm and greater and removed for wavelengths 369 nm or less. Spectrum scan and storage – Supports spectrum scan, display, subtraction, storage, and playback, in addition to standard tunable absorbance and UV/Vis functionality. Cuvette qualification – Facilitates qualification of the detector by insertion of a standard in a cuvette without breaking any fluidic connections. This feature also allows you to use the 2487 Detector as a benchtop spectrophotometer. Cuvette sample analysis – Allows the spectrum of any sample placed in the cuvette to be recorded. Method editing and storage – Supports basic method programming, storage, and retrieval from the front panel. Full diagnostic capability – Supports built-in diagnostic tools to optimize functionality and performance. Backward compatibility – Operates as a 486 Detector with PowerLine, Millennium32 software versions lower than 3.0, and other Waters products connected via the LAC/E interface using the IEEE-488 bus. Two contact closure outputs – The 2487 Detector has two configurable switches, each of which can accommodate a maximum of +30 Vdc, 1.2 A current carry, and 0.5 A current switching. The switches (SW1 and SW2) can trigger fraction collectors and other external devices, as well as activate based on time, absorbance threshold, or ratio criteria.
