With so many material options, density variances, absorbency capacities and more, selecting the right swab for your application can be a challenge. Here, Berkshire breaks down some of their most commonly asked questions about swab construction.

  1. What does PPI mean? A standard measure of foam density, the PPI of a swab refers to the number of cells per cubic inch in the foam membrane.
  2. What are reticulated or open cell foam swabs? The cell windows in these structures have been removed by either chemical or thermal means. These swabs typically exhibit excellent particle entrapment and liquid retention capabilities.
  3. What are non-reticulated or closed cell foam swabs? Entirely sealed with cell windows intact, non-reticulated or closed cell foam swabs feature higher density and durability, yet a lower absorption capacity than open cell foams.
  4. What are knitted polyester swabs? Engineered for chemical resistance, knitted polyester cleanroom swabs offer exceptional purity, durability and absorbency with low ionic contamination levels.
  5. What are non-woven polyester swabs? Compatible with most solvents, these swabs are absorbent and non-abrasive with low contamination and NVR levels.

Luxo’s Most Common Questions: Part 2

by Michelle R. on April 14, 2014

In this exclusive three-part blog series, we’ve asked the magnification experts at Luxo to reveal some of their most commonly asked questions. For our second installment we’ll focus on the Luxo trinocular microscope. What should you do if the camera won’t work?  

First, be sure the camera’s USB cord is connected to both the camera itself as well as to the PC. If you’re working with a stereo zoom Luxo trinocular system, locate the knob on the rear of the body. Try pushing it in or pulling it out. If the camera still isn’t working, check the software to ensure it has been properly installed and is recognized by the PC. If all these measures fail or if you are working with a different trinocular system, contact Luxo directly for additional support at (800) 222-5896.
