Overview

The BeadBath Duo series are the first laboratory baths designed for precision temperature control when used with water, or with (the increasingly popular) Lab Armor® thermal beads. Unlike any other laboratory bath, they feature a “MODE” button that can be used to toggle between “Bead” or “Water” mode. Choosing the correct mode will automatically adjust the operation and balance of the multiple internal heating and sensing elements to ensure optimal performance. The result is one combination bath that is suitable for accurate, and uniform temperature control in either condition.

While the majority of research laboratories today are using water baths, many prefer the convenience of bead baths due to the advantages listed below. With the BeadBath Duo, the lab gets the best of both worlds, allowing conversion from one bath type to the other, with the simple press of a button.

Features:

  • Two separate modes for BEADS or WATER
  • Quik-Cal™, simple in-lab calibration function
  • Offers all of the advantages of a “Bead Bath”
    • Eliminates constant refills (Burn-out protection)
    • Easy (accessory free) securing of tubes and bottles
    • Allows angled incubations
    • Runs constant (no wait for heat-up)

Good enough
Color: Oak, Size: 24" W x 7" D x 1.5" H (2 pieces)
It’s a cheap shelf but it works for a starter apartment

Easy and good looking.
Color: Black, Size: 24" W x 7" D x 1.5" H (2 pieces)
Installation is pretty straight forward. Small level is included to make sure they are put up correctly. They look good up on the wall.

Shelf wobbles and sits at an inclined angle after mounted.
Color: Oak, Size: 28" W x 7" D x 1.5" H (2 pieces)
While the shelf looks nice, it didn't work as it should. I anchored and screwed in the black metal bracket pretty well, and it stays perpendicular to the wall and doesn't wiggle or wobble one bit. But as soon as I slide in the wooden shelf, the whole shelf wiggles and settles at an inclined angle. Putting in the two screws down on the shelf did nothing to help with the wobbliness. I may have to glue down certain big decoration in fear of it sliding down the shelf, though that may be a bit overcautious and exaggerating.
