UNICO Reflectance Measurement Attachment

Manufacturer: COLE-PARMER Brand: Cole-Parmer

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 SpectralaxTM data collection software (sold separately as part number 39459-14) to save data in ExcelTM format. This easy-to-use software will automatically prompt you through set up and use. 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

Manufacturer: Thermo Scientific Brand: UV-Vis Model: 222-265700

The Thermo Scientific Spectronic 200 single-beam visible spectrophotometer has a spectral bandwidth of up to 4nm, 340 to 1000nm wavelength range, and a tungsten halogen lamp, and is used in teaching laboratories to provide students with hands-on experience with the principles and methods involved in spectrophotometry. The instrument performs automatic zero %T at startup to ensure accuracy. It has a live display of ABS and %T, and performs quantitative (Beer's Law) and OD600 cell-growth analysis. The adjustable tilt screen can be set at preferred viewing angle and folds away for storage. The wavelength setting can be adjusted in 10nm or 1nm increments using the coarse/fine adjustment knob. The built-in cuvette and test tub rack accepts 10mm square cuvettes and test tube cuvettes up to 25mm diameter. The sample compartment holds up to 250mL of spilled liquid and is removable to ease cleaning. Plastic construction resists acid solutions, and the lid covers the control panel and screen to protect against samples during loading and unloading procedures. The keypad is sealed to prevent spilled liquids from damaging the instrument. All exterior surfaces are sloped to shed spilled liquids. The instrument has two USB ports for connection to a PC (sold separately).
