Description
Screw-cap tubes with PP closure and flat bottom (Ø 20 x 150 mm) are borosilicate glass laboratory tubes designed for sample collection, storage and general laboratory processing. They carry a 15-415 screw thread and are fitted with a neutral polypropylene closure with PTFE seal for dependable sealing against many laboratory chemicals. Manufacturer information also lists an alternative black phenolic resin cap with silicone seal, so users can match the closure to their application. The larger 20 mm diameter provides greater working volume than narrower formats while the flat bottom ensures stable placement on benches and in tube racks. Borosilicate glass delivers the thermal and chemical durability expected in everyday lab work, and the tubes are autoclavable for standard sterilisation cycles. Supplied by manufacturer Labbox in packs of 100 pieces, these tubes suit chemistry, life-science and QC environments that need robust screw-cap glassware with consistent geometry for aliquoting, incubation and short- to medium-term sample holding.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Test tubes with PP screw cap, flat bottom, Ø20 x 150, 100 pcs
What is this article?
Test tubes with PP screw cap, flat bottom, Ø20 x 150, 100 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Labware.
A flat-bottom flask stands on the bench without a cork ring, which a round-bottom flask will not do. It is for heating on a plate and for simple setups. It is a poorer shape than a round bottom for even boiling under vacuum.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
