Float Rack
Product Code : EL-TT-10143
Quick answer: This is a compact, autoclavable polypropylene rack designed to float on the surface of a water bath, holding 16 microcentrifuge tubes of 1.5 ml each upright for incubation. A raised alphanumeric grid on the surface identifies each tube position, and a central rod handle makes it easy to lift the loaded rack in and out of the bath.
Why a Floating Rack for Water Bath Incubation
Incubating microcentrifuge tubes directly in a water bath without support risks tubes tipping, floating away individually, or taking on water if they are not fully sealed. A floating rack holds a full set of 16 tubes upright and together at a consistent depth in the water, which keeps incubation conditions even across the batch and makes it simple to lift the whole set out at once rather than fishing for individual tubes. This is routine in microbiology and immunology work, where multiple samples often need identical incubation time and temperature. The raised alphanumeric grid lets a user record and find a specific tube's position at a glance, which matters when tracking multiple samples through a single incubation run, and the central rod handle keeps hands away from the warm water surface when loading or retrieving the rack.
Frequently Asked Questions
How many tubes does this rack hold?
It holds 16 microcentrifuge tubes of 1.5 ml each, arranged for even spacing and stable flotation in a water bath.
Can this rack be autoclaved?
Yes, it is autoclavable, allowing it to be sterilised between uses along with other polypropylene labware in the same cycle.
How does the alphanumeric grid help during use?
The raised alphanumeric index on the rack surface lets users identify and record each tube's exact position, which is useful for tracking multiple samples through the same incubation run.
