Test tubes

Introduction to Test tubes

Test tubes are cylindrical labware with round or self-standing bottoms, commonly used in laboratories for containing samples, mixing solutions, heating, performing chemical reactions, or culturing microorganisms. Depending on analytical requirements, users can choose between glass test tubes (such as borosilicate or soda-lime glass) and PP plastic test tubes.

When selecting products, buyers should consider the material, diameter and length dimensions, capacity, and rim style, such as beaded rim, straight rim, or GL screw cap. For specialized applications, factors such as graduations, sterility, self-standing bases, or centrifugal resistance are also criteria to evaluate. Hoa Viet currently distributes test tubes from manufacturers including Aptaca (Italy), Assistent (Germany), Duran (Germany), and Kimble-DWK (USA).

Should I choose glass test tubes or PP plastic test tubes?

Glass test tubes are suitable for direct heating, synthetic chemical analysis, or reusable culture applications. Conversely, PP plastic test tubes are ideal for sampling procedures requiring tight caps, volume graduations, impact resistance, or centrifugation.

What is the difference between rimmed and rimless test tubes during use?

Rimmed test tubes enhance mechanical strength around the rim, facilitating secure gripping with clamps and easier liquid pouring. Rimless test tubes are typically preferred when used with rubber stoppers, laboratory cap closures, or when loaded into specialized racks.

Can Aptaca plastic test tubes be autoclaved and centrifuged?

The Aptaca PP plastic test tube line can be autoclaved at +121 °C. In addition, the products can withstand maximum centrifugal forces up to 6.000 g.
