Floating Microtube Rack
Product Code : EL-BLS-10963
Last updated: 6 October 2026
Quick answer: A polypropylene floating rack holding 16 filled 1.5 mL microcentrifuge tubes in a 4 x 4 inch array for water or ice bath incubation, with temperature resistance from -70 to 100 degrees C and a moulded-in handle.
A floating rack solves the problem of incubating tubes in a water bath without clamping anything: it sits on the surface with the tubes held below the lip so the conical ends are immersed while the caps stay dry. This rack is stated to float with a full load of filled tubes, which is the part cheaper racks get wrong.
The temperature resistance is the standout figure, -70 to 100 degrees C, which covers a heat-shock step at one end and freezer storage at the other, so the same rack follows the sample through a transformation protocol. Capacity is 16 filled 1.5 mL tubes in a 4 by 4 inch array. A moulded-in handle allows transport, agitation and removal from the bath without tongs, and on the bench the rack legs keep the tube bottoms off the surface.
Note that this family lists a second product under the same name with different specifications, a 20-tube version sized for a 1 litre beaker. Quote the capacity and temperature range you need, not just the product name, when ordering.
Note: a second, different product is listed under this same name in the catalogue, holding 20 tubes and sized for a 1 litre beaker. Specify the capacity and temperature range you require when ordering, as the name alone does not identify which rack you will receive.
