Lab Consumables

Here’s a concise introduction to common laboratory consumables :

---

### **1. Pipette Tips**  

**Function**: Attach to pipettes for precise liquid handling (0.1–1000 µL).  

**Uses**: Transferring samples, reagents, or buffers in molecular biology, diagnostics, and cell culture.  

**Key Features**: Disposable, sterile (filter tips prevent aerosol contamination), and compatible with specific pipette brands.  

---

### **2. Centrifuge Tubes**  

**Function**: Hold samples during high-speed centrifugation to separate components by density.  

**Uses**: DNA/RNA extraction, cell pelleting, or protein purification.  

**Key Features**: Made of durable polypropylene (PP), available in volumes (0.5–50 mL), with conical or flat-bottom designs. Autoclavable and chemical-resistant.  

---

### **3. Deep-Well Plates**  

**Function**: High-capacity microplates with large-volume wells (1–2 mL per well).  

**Uses**: PCR setup, sample storage, or compound screening in high-throughput workflows.  

**Key Features**: 96- or 384-well formats; made of PP or polycarbonate (PC). Compatible with automated liquid handlers.  

---

### **4. Serological Pipettes**  

**Function**: Graduated pipettes for accurate dispensing of larger liquid volumes (1–50 mL).  

**Uses**: Media preparation, cell culture, or transferring sera/buffers.  

**Key Features**: Sterile, disposable, and used with manual or electronic pipette controllers. Available in polystyrene (PS) or polyethylene (PE).

### **Shared Characteristics**:  

- **Sterility**: Critical for contamination-sensitive applications (e.g., cell culture).  

- **Material Compatibility**: Resistant to chemicals, heat, or freezing (e.g., PP for extreme conditions).  

- **Standardization**: Sizes/designs align with lab equipment (e.g., pipettors, centrifuges).  

These consumables are essential for accuracy, efficiency, and reproducibility in research, clinical, and industrial labs.
