Disposable plastic consumables are commonly used in laboratories for a variety of applications, including sample collection, preparation, processing, and storage. These consumables are typically single-use, which helps prevent cross-contamination between different experiments, ensuring that each experiment's results are not affected by residues or microorganisms from previous trials. Here’s a classification of common disposable plastic consumables used in modern laboratories from Cotaus.

1. Pipette Tips

Materials: Commonly made from polypropylene (PP) or low-binding variants for reducing sample loss in molecular biology applications.
Applications: PCR, ELISA, cell culture, DNA/RNA handling, and general liquid dispensing.

2. Centrifuge Tubes

Function: Used for spinning samples in a centrifuge to separate components based on their densities.
Materials: Often made from clear polypropylene (PP) for its chemical resistance and strength.
Common Volumes: 1.5 mL, 2 mL, 15 mL, 50 mL. (Cotaus Centrifuge Tubes 0.5 mL to 50mL)
Applications: Sample storage, cell fractionation, DNA/RNA extraction.

3. Petri Dishes

Function: Shallow, flat dishes used for growing cultures of bacteria, fungi, or cells.
Materials: Typically made from polystyrene (PS) for clarity, but some are made of polyethylene terephthalate (PET) or other polymers.
Applications: Microbial culture, tissue culture, and cell growth experiments.

9. Transfer Pipettes (Disposable)

Function: Used for transferring small volumes of liquid or reagents.
Materials: Low-density polyethylene (LDPE) or polystyrene (PS).
Applications: General laboratory work, reagent transfers, and liquid handling.

10. Cell Culture Plates (Multi-Well Plates)

Function: Used in cell biology to culture cells in a controlled environment, with multiple wells for parallel experiments.
Materials: Polystyrene (PS), sometimes treated for enhanced cell attachment.
Applications: Cell culture, high-throughput screening, and assays.
Cotaus Cell Culture Plates Specifications: 6 well, 12 well, 24 well, 48 well, 96 well
