2013 Centrifuge Product Survey Results

By Lab Manager

When it comes to common technology in a laboratory, centrifuges rise toward the top of the list. Centrifuges separate particles and structures suspended in liquid by applying thousands of gravitational force equivalents to the sample through spinning and play a role in a wide range of workflows and applications.

Top 5 Questions You Should Ask When Buying a Centrifuge

1. What is the maximum g-force the centrifuge can generate?

2. How does the company’s centrifuge differ from other ones that can do the same speed & capacity?

3. What kind of warranty comes with the centrifuge & what does it cover?

4. If the company discontinues the product, for how many years do they provide accessories and parts for the centrifuge?

5. Ask about cost of the purchase— not just the price of the product being installed but the total cost of ownership including price, service expectations, warranty, etc.

The typical way labs train staff in centrifuge operation:

On-the-job training by fellow worker 89%
Vendors 4%
Have to learn it on our own 4%
Videos, books, etc. 2%
Off-site training courses 1%

The following hazards exist relating to the centrifuge(s) in readers’ labs:

Physical hazards: Mechanical stress, metal fatigue, and corrosion of the rotor over time 40%
Exposure hazards: Aerosolization of biological, chemical, or radioactive materials 38%
Don’t know 30%
Other 6%

Completed Surveys: 243

Quit Micromanaging!

The slogan of the micromanager may well be “If you want something done right, do it yourself.” However, “Micromanagement stifles initiative and kills motivation,” according to a very successful manager, World War II General George S. Patton. Despite this, many of us have worked for micromanagers and some of us (this author included) have even been micromanagers. Why do people micromanage? How can micromanagers change their ways?

Optimizing Laboratory Exhaust Systems

The creation of sustainable, high-performance and efficient buildings is growing in importance for companies and governments around the world for both economic and environmental reasons. In particular, laboratories are the focus of many of these reduction efforts as they are some of the largest consumers of energy due to the specialized equipment and ventilation systems required for safety and compliance.
