2015 UV-Vis Spectrophotometer Survey Results

Ultraviolet-visible (UV-Vis) spectrophotometry is arguably the most common as well as one of the oldest forms of absorption-based analysis. UV and visible regions of the electromagnetic spectrum are contiguous: UV wavelengths range from 10 to 4000 angstroms; they are visible from 4000 to 7000 angstroms.

Top 5 Questions You Should Ask When Buying a UV-VIS Spectrophotometer

  1. For what applications will you be using the instrument for? This will help you determine the detection range you require. Don’t forget to consider future applications that may require a broader range.
  2. What range of stray light performance are you comfortable with for your application and budget?
  3. Consider what sort of samples you’ll be working with in order to determine what absorbance range you will need in your UV-Vis spectrophotometer. For example, if it is a turbid or concentrated liquid or a solid sample that is optically thick, you may require a working absorbance range between 5 Å and 8 Å or higher.
  4. What level of throughput and reliability do you need?
  5. How much will the instrument cost? Don’t forget to factor in the cost of maintenance, etc. along with the cost of acquisition.

Remote Control

Over the past few years that we’ve covered laboratory gadgets and apps, we’ve continued to see this area grow and become more accepted in the lab. While this year’s releases have added even more benefits to those working in the lab, the most recent trend has been all about helping laboratory professionals even when they are outside the lab.

Secrets of a Successful Start-Up Lab

Many labs start out as entrepreneurial ventures to develop new technology. As such, a start-up lab has entrepreneurial requirements that must be met in order for it to successfully develop into a full-fledged business.

Selecting a SaaS LIMS

Okay, let’s jump straight to the point. You’ve performed your due diligence and have decided that to remain viable your laboratory absolutely must transition to a laboratory information management system (LIMS). That is an important step, but perhaps one of the simplest.
