What is an Analytical Balance?

Analytical balances are highly sensitive lab instruments used to measure mass accurately. These scales have a readability range of between 0.1mg to 0.01mg. They also feature a weighing chamber or draft shield to prevent air currents from affecting very small samples. They detect very fine increments in mass. Because of their sensitivity, a slight breeze or vibration can affect the readings. Therefore, they’re best suited for dedicated rooms with minimal disturbances.

Due to their sensitive scale, analytical balances must also be carefully monitored and calibrated regularly. Most laboratory analytical balances feature automatic internal motorized calibration and calibration using external weights.

Analytical balances typically come equipped with several functions and features. Most of them feature counting and check-counting applications which are useful when counting ingredients, pills, or tiny pieces.

Other analytical balances feature dynamic weighing, allowing lab professionals to weigh unstable samples such as small animals, liquids, and insects. Other balances also feature percentage weighing, allowing more efficient and quicker formulation in pharmaceutical and chemistry applications.

什么是分析天平？

分析天平是用于精确测量质量的高灵敏度实验室仪器。这些天平的可读性范围在 0.1 毫克到 0.01 毫克之间。它们还配有称量室或通风罩，以防止气流影响非常小的样品。它们能检测到非常微小的质量增量。由于其灵敏度高，轻微的微风或振动都会影响读数。因此，它们最适合用于干扰最小的专用房间。

由于天平的灵敏度较高，因此还必须定期对其进行仔细监测和校准。大多数实验室分析天平都具有自动内部机动校准和使用外部砝码校准的功能。

分析天平通常具有多种功能和特性。大多数分析天平都具有计数和校验计数功能，这在计数成分、药丸或小碎片时非常有用。

其他分析天平具有动态称量功能，使实验室专业人员能够对小动物、液体和昆虫等不稳定样品进行称量。其他天平还具有百分比称量功能，可在制药和化学应用中更有效、更快速地进行配方配制。
