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.

Labcon Tip Top™ Dispenser Caps
- Convenient and Easy: Just tilt the tube and squeeze Tip Top® slightly to dispense one drop onto a slide.
- Safe Dispensing: You don't need to open the tube preventing spillage and exposure to infectious agents.
- Very Low Evaporation: A flexible cap is available to cover the Tip Top® so you can store samples longer.
- Medical Grade Resins: USP Class medical grade resins and packaging.
Safe Dispensing of Blood Samples
Tip Top® Dispenser Caps A safe and cost-effective way of dispensing samples in your lab. The Tip Top® is a disposable cone shaped cap that fits all standard 13 or 16 mm blood collection tubes. A small opening allows you to dispense a sample without removing the Tip Top cap so you can prepare smears on slides or dispense into reagent wells or microcentrifuge tubes safely. Inside the tip of the Tip Top® is an integral porous filter that removes fibrin from the blood sample allowing for a perfect smear.
Tip Top® is a convenient alternative to pipetting from an open blood tube, just tilt the tube and squeeze to dispense one drop. And Tip Top® is safe you don't need to open the tube and pipet out of the tube so spillage is reduced along with potential exposure to infectious disease. Just carefully remove the stopper and replace with Tip Top®.
The Tip Top® dispenser cap can be used with almost any liquid. Made from chemically resistant polyethylene they can dispense serum, reagents, plasma, whole blood and CSF. The integral porous polyethylene filter efficiently separates serum and can also be used a a reagent blender.
Fits standard 13 x 100 and 16 x 100 collection tubes.

Labcon Security Cups for Urine or Specimen Collection
- 100 mL Cups
- Sample spouts may be cut with scissors or pierced with a syringe
- Impact and pressure resistant seal
These security containers are designed to provide secure and reliable tamper-proof seals for specimens in transit or storage. After specimen collection the screw cap is tightened first by hand, then by the special wrench, which engages teeth on the lids rim to create a locked and leak-proof seal. To access the specimen for testing procedures, large or small sample spouts may be cut with scissors or pierced with a syringe. Spouts can be resealed with the large or small plugs and returned to storage for further testing. The impact-resistant, durably constructed, and pressure-resistant seal offers excellent protection during handling and transport. Made of non-reactive polyethylene resin.

Labcon LTS Style Low Binding Tips - Bulk Lid
SuperSlik® Low Retention tips have a proprietary modified polypropylene surface that limits the adhesion of cells, rDNA, proteins, and other viscous materials. Their accuracy and precision is up to 10 times better with viscous samples than standard non-wettable polypropylene. SuperSlik® tips are made from our own proprietary resin formulation that uses no additives or coatings that migrate into your samples. Unlike low retention tips from many others, SuperSlik® tips use no restricted chemicals and meet RoHS regulations. The resin helps increase the contact angle of fluids and lets you dispense the maximum amount of sticky DNA molecules. These tips were developed in our own laboratory and have been found to be ideal for viscous samples. Low retention tips are best suited for pipetting thick or sticky fluids and may not be appropriate for all uses.
