Manufactured and designed using only high-quality borosilicate glass 3.3, our stoppered test tubes undergo rigorous class A conformance testing. This type of glass is well known for its thermal and chemical resistance. Each tube comes with a pair of snug borosilicate or polyethylene (optional) stoppers which guarantee sample integrity by preventing contamination or evaporation.

While serving controlled storage, sample transport, or reaction containment, the glass test tubes with stoppers also come in various capacities from 5ml to 50ml. In experiments, the high clarity and uniform wall thickness of the glass avoid ambiguity and guarantee reproducibility.

Features Of Stoppered Test Tubes

● Prevents ingress of air and leakage with tight sealing stoppers due to ground and flat rims

● Made using autoclavable, reusable, and borosilicate glass 3.3 construction which is can withstand sudden temperature changes

● Stoppers in glass and plastic provided optionally according to requirements for different chemical compatibility

● For OEM/ODM projects, custom logo and volume markings are available

● Smooth, defect free inner surface to reduce adhesion of sample

Our test tubes maintain precision, durability, and long-term cost effectiveness in highly demanding environments.

Applications Of  Stoppered Medicinal Test Tubes

● Diagnostic pathology

Safe retrieval and storage of biopsy fluids or small-volume samples Long-term retention of fixed specimens.

● Chemistry & physics labs

Preservation of volatile or light-sensitive substances Severely controlled reactions-heat or pressure

● Biotechnology and microbiology

Incubation or transport of culture media samples Cultivation of anaerobic bacteria

● Clinical Medical laboratories storage

Performs temporary sealing of blood serum, plasma, or mixture of reagents Seals off specimens to sensitive diagnostics without contamination.

Their usefulness in science makes them invaluable in almost every discipline of laboratory science.

FAQ

Which stopper materials do you provide for your stoppered test tubes?

We provide glass stoppers for chemical compatibility and polyethylene (PE) stoppers for light weight and economical sealing. Custom shapes, colors, and other stopper design features can be made upon request.

Your stoppered glass test tubes can be autoclaved, correct?

Indeed, all of our borosilicate glass test tubes are autoclavable at 121 degrees Celsius which makes them handy for biologically sensitive material storage and biological materials sterile handling.

Do you have branding options for your test tubes aside from personalization?

Of course. As a manufacturer, we do provide OEM & ODM services which includes branding, packaging, and label free glass test tubes under the name of the customer.
