EW-39459-14 光度计
Laxco MicroSpek DSM-Dual Cell Density Meter/Photometer; Micro, Tubes, or Cuvettes
Simple and easy to use—dedicated to measuring cell densities in suspension at 600 nm No computer required to operate — fully integrated controls Small footprint allows use inside fume hoods, incubation chambers, anaerobic compartments, biosafety cabinets, or other environmentally controlled areas Store up to 1000 data points with the internal memory and display the results in graphical or tabular format — export to a spreadsheet using the optional software ( 39459-40 ) Data may also be recorded and displayed in time lapse format over seconds, minutes, or even hours The dual photometer accepts direct sample volumes as low as 20µL, or use with standard-sized 10-mm cuvettes (of varying capacities) or 14- to 17-mm round tubes Use a pipette to place your 20 µL sample directly onto the platform — wipe clean with a KimWipe after analyzing Use these portable, lightweight cell density photometers to measure the growth rates of E. coli, yeast cells and other biological agents in suspension at the 600 nm wavelength of light. Photometers measure % transmission (% T), logarithmic transmission absorption (Abs), and McFarland units — plus feature an intervalometer for time-lapse recording. The 600 nm LED light focuses on the sample through fiber optic cables to obtain the readings quickly—no warm up time required. A simple touch panel provides eight separate functions and is easily wiped down in the event of spills. The fully recharged battery assembly provides 30 hours of operation; recharge time is 12 hours when the instrument is turned off and the universal AC power adapter is included. You can easily extract data for further analysis then download results directly to a PC via USB port and software. For added convenience, purchase the Spectralax™ data collection software ( sold separately as part number 39459-14 ) to save data in Excel™ format. This easy-to-use software will automatically prompt you through set up and use.
