Do you mean is a meniscus always concave? If so, then no. For example, the meniscus of Mercury is convex.
Oil forms a concave meniscus when in a glass container due to its low adhesive forces with the container surface.
A meniscus occurs due to the adhesive and cohesive forces between a liquid and a solid surface. The curvature of the meniscus is caused by the differing surface tensions at the interface of the liquid and solid.
Oil is considered to be concave when placed between two surfaces, such as in a meniscus. This is due to oil having cohesive forces that cause the liquid to curve downward between the surfaces.
The meniscus of mercury curves in opposite directions depending on the container it is in due to the difference in adhesive and cohesive forces. In a glass container, adhesive forces dominate causing a concave meniscus, while in a steel container, cohesive forces dominate causing a convex meniscus. The direction of the curvature is determined by the balance of these forces.
The curved surface at the top of a liquid is called the meniscus. It forms due to surface tension, causing the liquid to either curve upwards (concave meniscus) or downwards (convex meniscus) at the edges where it meets the container.
The two types of meniscus shape are concave and convex. Concave meniscus has a curved surface where the edges dip below the center, like in a test tube. Convex meniscus has a curved surface where the edges rise above the center, like in a droplet of water on a surface.

Meniscus.
A meniscus, but whether it has a positive curve or a negative one depends on whether it wets the glass.
A meniscus is used in measuring liquids in a graduated cylinder. The bottom of the meniscus is the point that should be read to get an accurate measurement. The curve of the meniscus is caused by surface tension.
A synonym for the science word "meniscus" is "concave surface," which refers to the curved shape of a liquid in a container due to surface tension.
Meniscus is the curved surface of a liquid in a container; to measure correctly the volume in a graduated cylinder it is necessary to take into account the meniscus type, convex or concave.

mEniscus is the curve or crescent of the surface on a liquid or substance and can be concave or convex. The meniscus should be taking in to account when a readings made to make precise measurements.
A concave meniscus forms in a graduated cylinder with water due to adhesive forces between the water molecules and the walls of the cylinder. This causes the water to cling to the walls, resulting in a concave shape.
The surface is concave if the liquid is attracted to the container walls and convex if it is not
Yes, a flask can have a meniscus. The meniscus refers to the curvature of the liquid surface in response to the container's shape. A flask with a narrow neck can exhibit a concave or convex meniscus, depending on the liquid it contains.
