Polystyrene (VIS) and Methacrylate (UV-VIS)

Optically superior designs specifically for fluorimetry make this an excellent choice for nephelometry and spectrophotometry. A negligible variation in absorbance between the 4 optical sides allows readings from any side.

The polystyrene cuvettes are accurate in the 340nm to 750nm visible spectral range. The methacrylate cuvettes are accurate throughout the 285nm to 750nm UV-VIS spectral range.

Unico 2150UV Spectrophotometer

wavelength=200-1000nm,4nm bp

This new series of fully digital spectrophotometers are as simple and easy-to-use as they appear! The precise, 1200lines/mm grating monochromator will be welcomed by environmental, quality control, research and university teaching laboratories. A membrane keyboard logically positioned next to the large, two-line, 9-LED display allows the user to control the wavelength, set Zero Abs (100%T) automatically, and select the operation mode of either %T, Abs, or Concentration. The sample compartment accepts square cuvettes from 5mm to 100mm in length (cylindrical or rectangular) and test tubes from 10 to 25mm in diameter. The standard holder is a 4-position linear stage for 10mm path cuvettes. Optional accessories include convenient packages for long path cuvettes, test tubes, micro cuvettes, temperature control (Peltier or water bath), and automated peristaltic pumps for flowcells (with or without temperature control).

The narrow 5nm bandpass is a perfect match for the high stability and accuracy required in the wavelength ranges of either 325 to 1000nm (Model 2100), or 200 to 1000nm (Model 2100-UV). The operator has the option of controlling the instrument through our UNICO Application Software (p/n 2100-401) for PC's. This low-cost package allows for the data collection for %T/Abs/Concentration, Kinetic applications and Standard Curve with 5 different curve fits (Least Squares, Linear Thru Zero, 2nd Order, Segmented or Slope/Intercept). Personal computer not included.

Spectrophotometer Model 1100RS

VIS, Single Beam, w/RS232,

This robustly built spectrophotometer combines a surprisingly high level of performance with a budget price. Wavelength is set from a simple rotary control and the instrument is ready within just a few minutes from switch-on. A membrane keyboard positioned next to the large, clear LCD display allows the operator to rapidly switch between %T and Absorbance and to set Zero Abs/100%T. The 20nm bandpass and wavelength range of 335 to 1000nm provides the accuracy required for vast applications in quality control and teaching laboratories.

Model 1100RS

This spectrophotometer shares the basics of the Model 1100, but with better accuracy and precision. The membrane keyboard positioned next to the large, clear LCD display allows the operator to rapidly switch between %T, Abs, and Concentration modes, and to automatically set Zero Abs. (100%T). The narrow 10nm bandpass is ideally matched to the wavelength range of 335 to 1000nm. Standard output includes an RS-232C for connection to a computer and the optional UNICO Application Software for Window's 9x. This low-cost program expands the capabilities to include Kinetics and Standard Curve with up to 5 calibration curve fits.

The sample compartment of the 1100 Series accepts either 10mm rectangular cuvettes, including disposable semi-micro cuvettes, or test tubes (standard). Optional holders expand the capability for COD vials or test tubes up to 1 inch in diameter. Both models are great for environmental, quality control, and teaching laboratories.

OD600 DiluPhotometer

The OD600 DiluPhotometer™ is a small, easy to use instrument that is dedicated to measuring samples near the 600 nm wavelength. It is suitable for measuring growth rates of several cell types including E. coli and yeast. Use of the OD600 DiluPhotometer™ with Implen's DiluCell™ 10 or DiluCell™ 20 facilitates the measurement of low volume samples (volume requirement of 200 µl and 100 µl respectively). The two different available DiluCell™ 10 or DiluCell™ 20  versions allow for automatic 1/10 and 1/20 dilutions. With a bandwidth of 40 nm, the OD600 is also suitable for protein quantification assays like Bradford (595 nm). The small size and portable nature of the OD600 DiluPhotometer™ make it convenient for use in incubation cabinets and under anaerobic conditions.

The OD600 DiluPhotometer™ has been designed for the spectrophotometric analysis of bacterial and yeast growth rates and the quantification of proteins at a wavelength nearby 600 nm (e.g. Bradford). The instrument is battery operated and can be easily transported for usage in incubation cabinets and under anaerobic conditions. The batteries last for almost 1 month when fully charged. A 600nm LED source in combination with a fiber optic is used to obtain the optical density measurement. Spills can be easily wiped from the surface, and the cell compartment area can be rinsed with, formaldehyde or ethylene oxide to sterilize it.

 

Lambert-Beer-Law

The Lambert-Beer-Law, also known as Beers Law, empirically relates the absorption of light to the properties of the sample. This law states that there is a logarithmic relationship between the transmission of light through a specific sample (T = I/Io with I = outgoing light and Io = incoming light), the molar extinction coefficient for a specific compound (), the concentration of the absorbing species in the material (c) and the distance the light travels (d). By leaving all conditions constant but changing the pathlength (distance the light travels), you can bend the Beer-Law to get an automatic dilution of your sample. This principle is realized within the OD600 DiluPhotometer with DiluCell.

 

Automatic Sample Dilution

Previously it was necessary to use standard cuvettes with a volume of at least 1 ml and additionally to dilute the sample manually. DiluCell from Implen allows for lower sample volume requirements and provides automatic virtual sample dilution. Due to the unique design of DiluCell cuvettes, the light-path is reduced from the standard 10 mm to 0.5 mm (DC 20) or 1.0 mm (DC 10). According to the Lambert Beer Law this shortened pathlength results in an automatic sample dilution by factor 20 (DC 20) or 10 (DC 10). Automatic dilution with DiluCell saves time and excludes dilution errors and cross contaminations.

 

Measuring Cell Density

The stage of growth of a bacterial culture needs to be monitored to ensure that the cells are harvested at the optimum point (towards the end of log phase) for the greatest density of live cells. The optical density of the sample indicates when this point has been reached. This value varies dependent on the cells being grown. Routinely cells are grown until the absorbance at 600 nm, also known as OD600, reaches approximately 0.4 prior to induction or harvesting. A linear relationship exists between cell number (density) and OD 600 up to approx. 0.6.
