Description
Changing block for 6 test tubes is a laboratory accessory designed to hold six 50 ml tubes with a diameter of Ø 30 mm in an organised, stable arrangement. This interchangeable block supports efficient tube handling during sample preparation, incubation workflows, and routine bench work where consistent positioning of conical or similar 50 ml vessels is required. Supplied as a single unit, the block weighs 0,740 kg and provides a compact footprint suited to thermal shakers, dry baths, or related modular heating and mixing platforms that accept dedicated tube inserts. Its six-position layout helps laboratories process multiple samples in parallel while reducing the risk of tip-over or mix-ups on crowded benches. Manufactured by THERMO SCIENTIFIC, the changing block integrates into existing modular systems that rely on quick-swap inserts for different vessel formats. Ideal for life-science, analytical, and general laboratory environments that routinely work with 50 ml tubes, it offers a practical way to adapt equipment to this common vessel size without redesigning the main instrument. Clear dimensional matching to Ø 30 mm tubes supports reliable seating and heat or motion transfer where the host device is designed for such blocks.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Changing block for 6 test tubes, 50 ml (Ø 30 mm), 1 unit(s)
What is this article?
Changing block for 6 test tubes, 50 ml (Ø 30 mm), 1 unit(s) is the article on this page. Luminix Health distributes THERMO SCIENTIFIC for laboratory use. It sits in Centrifuge tubes (conical), inside Tubes & vials, in Labware.
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.
