Push Cap Green 16mm for 10-12 ml Tube

What Are Plastic Test Tubes?

Plastic test tubes are cylindrical laboratory containers designed for storing, mixing, heating, or temporarily holding liquids. These versatile tools are essential for modern laboratories in biology, chemistry, and medical research. Properly manufactured plastic test tubes ensure reliable results while maintaining safety during experiments with various substances.

Main Functions of Plastic Test Tubes

Plastic test tubes with caps serve a wide range of laboratory tasks:

• Conducting chemical reactions — controlled environment for experiments

• Sample collection and analysis — collection of urine, blood, saliva, or other biological materials with sterile surfaces for accurate testing

• Centrifugation — round-bottom plastic test tubes can withstand high-speed rotations for separating liquids

• Temporary storage of reagents or media — short-term containment of active substances

• Educational experiments — used in schools and universities to safely demonstrate chemical processes

Many plastic test tubes are available with a cap system, including the reliable Push Cap Green 16mm or Push Cap Green options. These Push Cap for Tube designs simplify sealing and reduce contamination risk, making them ideal for clinical or research settings.

Types of Plastic Test Tubes

When selecting plastic test tubes, several factors should be considered:

By material:

• Polypropylene (PP) — chemically resistant, disposable

• Polystyrene (PS) — clear and lightweight, suitable for non-reactive samples

By volume:

• 5 ml — small-volume applications, commonly used in labs

• 10 ml — standard size for general testing

• 15 ml — medium-volume experiments

• 50 ml — large liquid volumes

By cap type:

• Screw caps — tight and secure

• Snap caps — quick closure

• Push Cap for Tube — convenient, fast, and reliable, including Push Cap Green 16mm

• Open top — for experiments without storage

By bottom shape:

• Flat bottom — stable when placed

• Round bottom — optimized for centrifugation

By sterility:

• Sterile — individually packaged

• Non-sterile — for general lab use

By graduation:

• With measuring marks for precise dosing

• Without marks for simple applications
