Lab Armor® Beads

- Watch the video in the link above to learn more! 

Lab Armor Beads are dry metallic beads that replace water/ice/oil/sand in baths, giving old equipment a cool, shiny, state-of-the-art upgrade. Eliminates water bath contamination, harmful germicides, and unpleasant maintenance. 

Beads are dry and naturally more resistant to microbial growth than water, and therefore, are less likely to harbor and contribute to transmitting microorganisms in the laboratory. 
  

Lab Armor Beads will help you save time and money. No more hassling with emptying, cleaning, and refilling water baths.

The bath stays on so there is no need to plan around warm-up times. Lab Armor Beads eliminate the worry about low water burnout because there is no water to evaporate.
 

Other Benefits of Lab Armor® Beads: 

• Cleaner working environment.
• Greater organization capabilities as samples are held in place without racks or other accessories.
• Environmentally friendly. 

Why Choose Lab Armor Beads?
 

Any Vessel, Any Angle

Lab Armor Beads prevent distorted data and dangers resulting from inaccurate temperatures, evaporated lab water baths, and water-exposed contaminated samples. The Beads are designed to decrease microbial contamination that can ruin experiments or lead to safety issues in the laboratory.

Organized and Secure

Lab Armor Beads flow fluidly and can conform to all sizes and shapes of vessels placed within the bath. Vessels that are prone to tipping over or floating away no longer require racks, floats, or bottleneck weights to secure them in place. Sample vessels can be conveniently buried into the beads to avoid temperature gradients associated with exposure to room temperature air. Bottles will rest on the surface and conical tubes will stay firmly in place in less than 1/2 inch of Beads.

Specifications

• Temperature range: -80°C to 180°C
• High thermal conductivity
• Non-toxic, non-vaporizing, antimicrobial
• No daily requirement for biocides, germicides, or other cleaners
• No gray water
• Smooth rounded shape allows fluidity and will conform to many sizes and shapes of vessels
• No racks, floats or weights required to hold items in place
• Recyclable*
• Weight 4 Lbs. (1.81 kg) per Liter 

*Must follow biohazard disposal protocols if beads have been used in biohazardous work.
