what is the name of the gray pipette

The "gray pipette" typically refers to a specific type of pipette used in laboratory settings, often identified by its color coding, which is common in adjustable-volume pipettes like those from brands such as Eppendorf or Thermo Fisher.

1. **Name of the Gray Pipette**: Often, a gray pipette may refer to a pipette that accommodates a specific volume range, particularly 10-100 µL. However, the exact name can vary by manufacturer.

2. **Range of Pipette Volume**: The volume range of pipettes can vary significantly based on the type and model. For standard single-channel pipettes:
- P2: 0.2 - 2 µL
- P10: 1 - 10 µL
- P20: 2 - 20 µL
- P100: 10 - 100 µL (often the gray pipette)
- P200: 20 - 200 µL
- P1000: 100 - 1,000 µL

3. **Maximum Pipette Volume**: The maximum volume for a pipette can vary. For example, a P1000 pipette has a maximum volume of 1,000 µL (or 1 mL). Larger capacity pipettes may go up to 10,000 µL (10 mL) or more, depending on the specific model designed for higher volume liquid handling.

To provide more precise information, it would help to know the specific pipette model or manufacturer you're referring to.
