Excellent results with high level of repeatability and accuracy.
Application Area: Formaldehyde Determination
"Quantitative analysis of formaldehyde in water was achieved with a high level of repeatability, and accuracy and with rapid acquisition of spectra. The use of test kits allows for fast and simple analysis, avoiding mixing and weighing of hazardous chemicals, and enables the concentration of formaldehyde to be determined without a calibration curve and by multiplying the measured absorbance at 565 nm by a known factor. Quantitative analysis using UV Lab software provides immediate results."

Severe Issues with the filter sets in daily use environments
Application Area:Fluorescent Antibody Conjugates
"These instruments have severe issues. In particular, they have issues over time with discontinuities in the signal reported. Basically the signal jumps up and down when the device changes to certain filters. According to the repair tech who did the repair, in higher use environments the intense lamp light will actually burn the filters and cause them to degrade which results in the signal issues we were seeing. He showed us on the filter wheel the burn marks on the filters. This was the most common issue I have seen (common across all four instruments at three different locations) but was certainly not the only one; a stepper motor died twice as well. If memory serves me correctly, we had to call between 5+ times a year per instrument. Combine this with issues in significant variance on day to day runs and we ended up getting rid of these instruments at the last place I worked, replacing them with a competing plate reader instrument which allowed us to reduce variance by an order of magnitude."

"Our lab purchased the Perkin Elmer Lambda 25 for use in two applications, where the measurement of only one wavelength is needed. The software does have extensive capabilities for collecting scan and kinetics data, so I will be using it to explore other analysis methods for our laboratory. The software contains wizards to enable the easy setup of new applications. Applications support is available from Perkin Elmer, one just needs to call and describe their needs. It is not clear to me what accessory I need to enable the use of our 10 cm cells, but I will contact Perkin Elmer to address this. "

"This is an easy to use product with many different features. It has software that can produce method variability and advanced results. It also has very good product support because it can be supported by a PerkinElmer technician that will come out and do preventative maintenance on it. We have been using it for 2 years and have not had a problem with the system as of yet. It is easy to calibrate and easy to use overall. I would recommend this product to anyone who is looking for a UV/Vis."

"The instrument did not come with any training instead they installed a manual on the computer. There are two possible programs to use and the older and newer program do not give the same results. I don't know which one to trust. I am disappointed with this purchase but perhaps it would be fine if it included training that has been included with every other instrument purchase I have ever encountered."

"This instrument at times can be difficult to use because it freezes and when zeroing and it glitches at times. But when working properly it is a great instrument to use and is accurate. I like how the program displays more than one trail. Very simple to put in cuvette the right way and has two slots for the cuvette. Once sample is in and zeroed correctly the UV-Vis is simple to use. At times it is difficult to find the right tools to display the graph."
