Top 5 Questions You Should Ask When Buying a Freeze Dryer

  1. What solvents are you using? A temperature differential between the sample’s eutectic temperature and collector temperature of 15–20 degrees is required. If solvents such as acetonitrile are used, a cascade freeze dryer is required.
  2. How much sample in liters will you run? When choosing a freeze dryer, vendors recommend loading 1/2 of the listed capacity. For example, a 6L freeze dryer will hold 3L during the run.
  3. Do you want to freeze dry in flasks, tubes, or bulk? Many drying accessories are available. On a manifold or drying chamber, flasks can be placed on each port. Test tubes and serum vials can be placed inside of the flasks for multiple samples per container. If samples are bulk, a tray dryer would be a good choice.
  4. Do you need to stopper under vacuum? Accessories can allow you to stopper under vacuum or nitrogen without using compressed gas.
  5. Is this a shared freeze dryer? A hybrid pump is recommended to prevent damage to the pump.

Run Your Lab Like A Business

When looking at best practices for running a lab, things as seemingly diverse as staff development and retention, inventory management, procurement, and efficient use of training spends, need to be looked at together. After all, equipment is only as good as the staff who uses it and your staff is only as good as their training.

Halting Hackers

With headlines screaming about hacking, of the latest James Bond movie Skyfall most recently, of national and nuclear weapons laboratories not so long ago, and of businesses and individuals almost on a daily basis, it’s no surprise that worldwide information technology (IT) security spending is set to hit $77 billion in 2015—almost 8 percent more than this year’s $71 billion, according to IT researcher Gartner, Inc. 

Transporting Samples

When we think of labs and how they operate, we’re mostly focused on testing and subsequent results—the technicians’ abilities and conditions inside the facility where sample research and measurements take place. It’s less often that we focus on how the samples arrive at the facility. However, sample transport is an important part of a successful laboratory operation. A healthy and timely sample is vital to accurate analysis.
