Meetbekers

Meetbekers are measuring beakers, cylindrical containers used to hold and approximate the volume of liquids in laboratory and educational settings. They typically have a flat bottom, a spout for pouring, and volume graduations printed or etched on the side. While they are useful for rough measurements and mixing, they are not designed for high-precision volumetry.

Most meetbekers are made from glass or plastic. Common glass options include borosilicate varieties that resist thermal shock and chemical attack, while plastics such as polypropylene and polymethylpentene offer impact resistance and light weight. They come in a range of nominal volumes, from small (about 10 mL) to large (up to 2 L or more). Standard forms include the low-form beaker with straight sides and a wide mouth, and occasionally tall-form versions with taller, narrower profiles.

Accuracy and use: meetbekers provide approximate volumes and are typically used for pouring, decanting, heating, and mixing liquids. Their tolerances are less strict than those of volumetric flasks or graduated cylinders. In many laboratories, Class A beakers offer tighter tolerances than Class B, but all are primarily suited for non-critical measurements. Temperature changes can affect readings, so measurements may be adjusted or noted accordingly.

Care and safety: glass meetbekers are fragile and should be handled gently, especially when hot. Plastic beakers may be compatible with certain chemicals but can absorb solvents or stain. Cleaning should follow material recommendations, and beakers should not be subjected to abrupt temperature changes to minimize breakage.
