The Iwaki 2752-015 Conical Bottom Microcentrifuge Tube is a small, disposable tube used to hold, mix, store, and spin small-volume samples in the laboratory. Each pack contains 50 tubes. Microcentrifuge tubes are among the most basic items in molecular biology, biochemistry, microbiology, and clinical laboratories. Almost every stage of routine work depends on these small containers, from sample preparation and enzyme reactions to storing aliquots.
The conical bottom is the main feature of this tube. During centrifugation, sediments such as cell pellets, DNA, or protein collect in the tapered tip. This lets the analyst draw off the supernatant with a pipette without disturbing the pellet. The same shape also helps when recovering very small amounts of remaining liquid. Microcentrifuge tubes are generally made of plastic that resists many aqueous solutions and common laboratory solvents. Iwaki is a well-known laboratory ware brand, which gives users confidence that tube dimensions are consistent and fit microcentrifuge rotors.
In Indonesia, this tube suits university research laboratories, diagnostic laboratories, and food and pharmaceutical quality control laboratories. It also fits teaching laboratories where students learn basic sample handling and centrifugation. The 50-piece pack is a practical quantity for routine bench work, small projects, and laboratories that want to keep a steady supply of reliable single-use tubes for daily sample preparation and storage.
- Pelleting cells and precipitates: the conical bottom collects cell pellets, DNA, or protein in the tip during centrifugation, so the supernatant can be removed cleanly.
- Nucleic acid and protein preparation: the tube holds small sample volumes through mixing, spinning, and washing steps common in molecular biology and biochemistry workflows.
- Enzyme reactions: the small disposable format works well for setting up enzyme reactions with small reagent volumes and keeps samples separate to avoid cross-contamination.
- Aliquot storage: dividing reagents or samples into single-use tubes reduces repeated handling of the stock, and the tubes stay organized in standard racks.
- Recovering small residual volumes: the tapered tip draws the last drops of liquid together, so analysts can recover very small volumes with a micropipette.

Keep unused tubes in their original packaging or in a closed, clean container. Store them in a dry place away from dust, direct sunlight, and heat sources, so they stay clean and keep their shape. Handle the tubes with clean gloves to limit contamination of the samples. Before using a new solvent or a demanding centrifugation setting, check that it is compatible with the tube and follow the centrifuge manufacturer's guidance on balancing and speed limits. Always close caps securely before spinning. These tubes are single-use. Dispose of used tubes according to your laboratory's waste procedures, especially if they contained biological or hazardous materials.
