Description
Interchangeable block for centrifuge tubes is a modular accessory for block thermostats, configured for 12 centrifuge tubes of 15 ml in Falcon® format. It allows laboratories to heat or cool conical centrifuge tubes in a dedicated multi-position block without changing the base instrument. The layout supports parallel sample handling for incubations, thawing, conditioning or other temperature-controlled steps common in molecular biology, cell culture support and analytical sample preparation. Supplied as 1 pc and weighing 1,000 kg, the block offers a stable seat for 15 ml Falcon® centrifuge tubes and promotes uniform contact with the thermostat surface. This interchangeable block from manufacturer Labnet International is intended for labware and laboratory appliance setups centred on block thermostats. Swapping to this 12 × 15 ml configuration helps match vessel geometry to the protocol while keeping sample positions clearly organised on the bench. It suits research, teaching and routine laboratories that standardise workflows around Falcon® 15 ml centrifuge tubes and interchangeable heating blocks for flexible temperature control.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Interchangeable blocks f. centrif. tubes, for 12 centrifuge tubes 15 ml, Falcon®
What is this article?
Interchangeable blocks f. centrif. tubes, for 12 centrifuge tubes 15 ml, Falcon® is the article on this page. Luminix Health distributes Labnet International for laboratory use. It sits in Centrifuge tubes (conical), inside Tubes & vials, in Matériel de laboratoire.
A centrifuge tube is conical so a pellet collects at the tip, and it is rated for a relative centrifugal force. A 15 mL tube and a 50 mL tube are different rotors. Polypropylene is the ordinary plastic. The cap has to survive the same force as the tube.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
