LAMBDA 25, 35, & 45 UV/Vis Spectrophotometers by PerkinElmer, Inc.

"Perkin-Elmer Lambda 25 is one of the good UV-Vis spectrophotometer. It can measure a wide range of wavelength and the software is easy to use. One drawback noticed - data is not saved by itself unless saved manually. "

"This is user-friendly and has two wavelengths that can be used. It has an easy extraction of data and method set up. It is a high quality instrument and fast. We have had a lot of support from the company, pre- and post- instrument set-up. "

"We use this PE Lambda 25 UV/Vis Spectrophotometer to analyze UV254. This is a fast, reliable, easy to understand and use instrument. We will continue to use this product when and if the need ever rises to replace the current one. "

"This is a reliable instrument. We have owned Lambda series for more than 18 years and will continue to use them. It is very reliable and easy to use."

"LAMBDA 25 from Perkin Elmer is very convenient to use. The software enable data analysis very easy."

"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. "

"The instrument is very easy to use. I have never needed to use the after sales service and as such I don't actually know how the service is but the product itself gets five stars for ease of use and the fact that it is robust enough that technical assistance has not been necessary. I could definitely recommend this product."

"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."

"This product although somewhat difficult to use at times is very good.  The time in which it takes to obtain a spectra is short and detailed, showing high resolution of peaks.  When malfunctioning the support staff and manual are very helpful.  When it was necessary to require a technician to come in it was done in a timely manner. Highly recommend this product."

"The lambda 35 instrument is very rugged and very user friendly as far as ease of maintenance and calibration. The only complaint I have is with the operating software, it runs very slowly at times and the service technician has not been able to explain why."

"It was simple to use and reliable over time. Problems have been minimal and results have been accurate. The value of the product for the price was acceptable."

"These products are very important for our lab. In our laboratory, we have synthesized and characterized some drug and metal complexes. For the synthesis and characterization, we must to use ultra violet spectroscopy, infrared spectroscopy, mass spectroscopy, nuclear magnetic resonance spectroscopy; thermal analysis system, magnetic susceptibility measurements, elemental analysis (C, N, H, S)."

"This lab equipment was easy to use and it was easy to load samples. Adding extra samples to the run was easy, although viewing multiple results on one graph was sometimes confusing."

"This UV/Vis is an extremely easy to use instrument and is also very affordable; I would definitely recommend it to a colleague. Its data acquisition times are very fast and the spectra obtained can be easily read and maximum absorption values can be determined with the click of a button. Overall, this is a great instrument for easy data acquisition and a great starting instrument for a novice analytical chemist to learn from."

"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."

"An easy to use software interface with instrument. Data retrieval and analysis made easier with Lambda UV/VIS."

"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."

"This product is used in most chemistry classes because it is a fast and easy.  It gives an accurate reading that is necessary to complete undergraduate labs. This is the only type of spectrometer I have used, but after analyzing the outcome of the data, results can be concluded that allow the data to be verified."

"I have the Lambda 35. Easy and simple to use. Service center is very helpful with issues. Software is user friendly."

"Scanning the background is simple and self explanatory but can take a while. The software is easy to use allowing for a range of UV-Vis analysis. Noise from the instrument is relatively low if correct techniques are followed and performed well."

"I use the Lambda 25, it is a very nice instrument with which we use to measure the absorbance of any kind of materials that work in the UV range. It is a very useful instrument especially working with fluorescence and dyes. The scanning rate is very fast and it gives the spectrum within seconds."

"Can measure small sample volumes, down to 3mL. The sample can be heated and cooled. The scan rate is fast."

"The spectrophotometer provides a stable signal with good signal to noise levels."

"The user interface of this product is not intuitive for undergraduates, however the built-in tutorial is good."
