Therapeutic Indications

The empty 2 milliliter perforable cap tube is mainly used for the collection, transport and storage of biological samples such as blood, plasma, serum and other solutions used for diagnostic, analytical or research purposes. It can be used in numerous areas, such as medical analysis laboratories for carrying out hematological, serological, microbiological or toxicological tests. The particular shape of the cap, which allows perforation by needle, also makes it suitable for procedures that require frequent sampling of sample portions without the need to reopen the test tube, limiting the risk of environmental contamination or exposure to potentially dangerous pathogens for the operator.

This tube is ideal for inclusion in the automated workflows of modern analysis instruments, ensuring compatibility and uniformity in procedures. Furthermore, it is also widely used in the collection of samples for mass screening, environmental monitoring programs or in the industrial sector when it is necessary to test the quality of solutions, reagents or product samples. Thanks to its small volume, it is particularly suitable when it is essential to reduce the waste of materials and contents that can be removed.

It is also recommended for the transport of samples between different locations, maintaining the hermetic seal even in the presence of temperature changes. The tube can be integrated into cold chain circuits for biobanks, guaranteeing the integrity and safety of the stored samples. It does not contain additives, therefore, it is suitable for both biological liquids and different types of chemical reagents.

Composition

Construction of the test tube: The empty 2 milliliter perforable cap test tube is made of high purity plastic materials, often in medical polypropylene or other polymeric material suitable for contact with substances intended for laboratory analysis. The body of the test tube is transparent, resistant to impact and mechanical stress, to guarantee maximum safety during transport or centrifugation. 

Cap: The perforable cap is generally made of a soft polymer of different colour, capable of maintaining an airtight closure even after repeated perforations and resistant to attack by chemical or biological agents. The closing system is designed to offer ease of use and excellent sealing. The internal sealing ring prevents accidental leaks and maintains pressure even in critical conditions.

There are no additives, preservatives, anticoagulants or chemical reagents inside the test tube, ensuring maximum flexibility of use for every laboratory need, from the collection of pure liquids, to biological mixtures, to solvents of different nature.

Contraindications

There are no known specific contraindications to the use of the empty 2 milliliter perforable cap test tube in a laboratory setting, provided that it is used exclusively for the intended use for which it was designed. The tube is not suitable for human use as a container for the administration of drugs, infusion liquids or solutions intended directly for patients. It is important not to use the test tube with substances or mixtures incompatible with the plastic manufacturing material, such as aggressive organic solvents, concentrated acids or strongly oxidizing agents not tested for compatibility, in order to avoid risks of deterioration or unwanted chemical reactions, which could compromise the integrity of the sample and the safety of the operators.

Do not use the tube for storage at temperatures higher than those recommended by the manufacturer of the plastic materials or for applications requiring sterility, if the product is supplied as non-sterile. Avoid reusing the tube to avoid cross-contamination or loss of safety and sealing characteristics.

Safety of the drug for the species

The safety of the empty 2 milliliter perforable cap test tube is guaranteed by the selection of biocompatible and non-toxic materials, free of phthalates, BPA or other harmful compounds normally regulated in the production of laboratory devices. The cap, if used correctly, minimizes the risk of exposure to blood-borne or biological pathogens, offering a protective barrier for both samples and operators when withdrawing liquids via needle or pipette. The product is tested to resist mechanical pressures generated during the centrifugation phase and withstands typical storage temperatures in the refrigerator and freezer.

The integrity of the test tube is fundamental for the safety of the laboratory, therefore any specimens that are damaged, deformed or have lost their hermetic sealing capacity must be discarded. The absence of additives or internal fragments reduces the probability of altering the results of sample analyses.

Precautions

Pay attention to the correct handling of the tube during all phases of collection, transport and analysis. It is important to wear personal protective equipment such as gloves, goggles, and biohazard devices according to your laboratory's protocols. Open the cap only when strictly necessary, preferably using perforation with suitable needles to avoid aerosolization of infected contents.

Do not use the tube for storing substances in conditions that are not recommended for the plastic material used (e.g. temperatures below zero without compatibility, or on direct heat sources). Store the tube in a clean, dry place away from sources of cross-contamination. Keep out of the reach of children and do not use the test tube for uses other than strictly laboratory ones.

Method of administration

The sample must be collected using a pipette, syringe or other suitable instrument, inserting the liquid into the internal part of the test tube without exceeding the maximum capacity of 2 milliliters to avoid the risk of spillage. The perforable cap allows for controlled sampling, either with a needle or a pipette, without removing the cap: simply insert the needle through the membrane and aspirate the desired quantity of sample. The test tube must then be placed in a vertical position in the suitable rack or transported according to the regulations in force for biological or chemical substances, making sure that the closure is secure. After use, dispose of the tube following laboratory waste collection protocols.

Treatment program

Not being a therapeutic product, the empty 2 milliliter perforable cap tube does not provide actual treatment programs. However, it is possible to implement precise protocols for the collection, storage and transport of samples, customizing the operating methods based on laboratory guidelines. For example, routines can be established for serial collection of samples, monitoring parameters over time, or defining regular collection and handling intervals in clinical or epidemiological research studies. The tubes can be inserted into automated workflows to facilitate traceability, sampling and timely recording of the analyzes conducted.

In case of prolonged storage, it is possible to adopt storage protocols in the freezer or refrigerator, always taking into account the compatibility of the plastic materials with the expected temperatures and proceed with a visual inspection of the tubes before use. Always follow the laboratory's internal instructions for handling tubes, including correct labeling, post-use disposal and checking for any residue or encrustations that may interfere with the analysis.

Target species

The empty 2 milliliter perforable cap test tube is intended for laboratory use for the collection, conservation and analysis of biological, chemical or other samples. It can be used without distinction of species, as its use is aimed at anyone who needs to treat liquids in small volumes for scientific, clinical, veterinary, environmental or industrial purposes. The analyzes of samples of human, animal and environmental origin are therefore included, in compliance with current regulations regarding safety, quality and management of laboratory devices.
