Compact and low maintainance

The Biochrom WPA Lightwave combines ease of use with flexibility, and the novel optics require no lid or moving parts  and use a Xenon source for high energy performance with longer lamp lifetime. Compact footprint saves valuable bench space. This instrument has a 2 year warranty and the Xenon lamp has a 3 year warranty. The Lightwave II+ is a higher resolution 3nm bandwidth version. 

Powerful and flexible

The instrument includes a large wide view display and in-built software providing flash scan, fixed wavelength measurements, kinetics and concentration with comprehensive graphics capability plus the ability to store up to 90 methods. On peak confirmation is also a feature of the flexible software. Concentration may be measured using either a factor, singlepoint calibration, multi-standard curves or alternatively there is a multi-wavelength mode where equations using absorbance values may be used for ratio calculations. Samples may be measured in 10, 20 or 40mm pathlength cells (glass, quartz or disposable).

Flexible data export options

Results may be printed to an optional integrated high quality graphical printer for a permanent record or exported via a USB connection to a suitable PC running Print Via Computer (PVC) software for advanced reporting and data storage or the optional wireless Bluetooth® accessory. Alternatively the optional SD card accessory allows laboratories to export to standard SD or SDHC memory cards. This will be particularly useful to laboratories wishing to clone methods and folders between instruments. Please note that only one optional accessory can be fitted to the instrument.

Pre-programmed methodologies for nucleic acid quantification (DNA, RNA and oligionucleotides), protein assays (BCA, Biuret, Bradford and Lowry) and for cell culture density measurements. The visualision of the nucleic acid scan is particularly useful, especially for RNA samples where impurities may be present in the 230 nm region, yet not have an adverse effect on the A260/A280 ratio. The system is compatible with disposable low volume UV cuvettes

In kinetics mode, the basic plot of absorbance against time may be supplemented with the result for äA/min plus the correlation coefficient is also calculated for the duration of the assay. This slope may be multiplied automatically by a factor to convert it directly to rate of reaction.

Flexible Data Export Options

Results may be printed to an optional integrated high quality graphical printer for a permanent record Alternatively results can be exported via a USB cable connection to a suitable PC running  Print Via Computer (PVC) software or wireless Bluetooth^®accessory (optional).

The Biochrom WPA CO8000 is a robust, easy to use instrument dedicated to the measuring of the density of cells in suspension such as E.coli, yeast, cells and other cell cultures. This hand held instrument has an integral battery allowing it to be taken to where the cell cultures are growing e.g. in incubation cabinets, under anaerobic conditions or even in a fume hood or safety cabinets.

This robust instrument will accept a variety of cuvettes and tubes- including 10, 12, and 16mm diameter test tubes meaning it can be used with Erlenmeyer side arm flasks. With no warm up time, just switch it on and it’s ready to use giving you results that are comparable to larger, more expensive spectrophotometers. The cell density of the cultures can be measured and the results stored in the memory. The results are given in Absorbance Units (OD). Once all measurements are taken, the up to 99 sample results can be viewed on the easy to read screen or the instrument can be connected to a PC or printer and the results downloaded.

This low maintenance instrument uses an indefinite life LED with fibre optics and no filters. The rechargable battery automatically recharges when connected to the mains and allows up to 1 month's normal use (under normal conditions) on a single charge. It is easily cleaned with ethanol or sterilized with formaldehyde or ethylene oxide.

It is important to note that cell cultures are turbid samples , so the Absorbance (OD) measured is due to light scattering, and not due to molecular absorption. Clumping together of cells will also affect readings, so the medium they are suspended in will also make a difference. This means that the actual reading obtained is very dependent on the collecting area of the detector after the sample and the optical geometry of the system. These vary depending on the make and model of instrument, so differences in readings between types of instruments are to be expected.

Key features

• Single beam LED cell density meter measures OD at 600nm
• Small, portable with rechargeable battery
• Long lifetime LED source with little maintenance needed
• Easy to use, clean and sterilise
• Stores up to 99 results to download later
