Description
Interchangeable block for test tubes, 12 × Ø 18 mm, is a modular heating-block insert designed for secure seating of standard laboratory tubes during controlled thermal work. The layout accommodates twelve positions with an 18 mm opening diameter, supporting parallel sample handling in routine incubation, warming, and temperature-equilibration workflows on compatible block thermostats. Supplied as a single piece with a stated weight of 0,752 kg, the unit is straightforward to exchange when protocols change tube formats, helping laboratories keep one base instrument flexible across methods. This accessory from manufacturer Thermo Scientific fits within labware setups for block thermostats where reproducible contact between tube walls and the heated block matters for consistent sample temperature. It is intended for general laboratory use in research, quality control, and analytical environments that rely on interchangeable blocks rather than fixed single-format heaters. Clear tube-count and diameter designation simplify selection against existing tube inventories and thermostat platforms. The compact one-piece format supports tidy storage beside the instrument and quick swap-over between runs, reducing downtime when switching from one tube geometry to another in multi-user or multi-method laboratories.
This article is part of Heating & cooling (other), in Heating, drying & cooling.

Questions about Interchangeable block for test tubes, 12 x Ø 18 mm, 1 unit(s)
What is this article?
Interchangeable block for test tubes, 12 x Ø 18 mm, 1 unit(s) is the article on this page. Luminix Health distributes THERMO SCIENTIFIC for laboratory use. It sits in Heating & cooling (other), inside Heating, drying & cooling, in Lab instruments.
This shelf holds heating and cooling equipment that is not a furnace, a mantle, a bath, an oven or an incubator. The question is still the range, the stability and what the heat actually touches.
Temperature equipment either holds a set point or drives a sample toward one. An oven dries. A furnace reaches the temperatures of ashing and melting. A bath surrounds a vessel with water or oil. A circulator moves that fluid. An incubator holds the mild warmth of a culture. An autoclave uses steam under pressure to sterilise. The number that matters is the temperature the article actually reaches, not the number painted on the dial. Temperature is part of the international system kept by the BIPM and compared by EURAMET.
