Using an Anti-vibration Table
Accuracy is essential for any weighing process, especially if you use sophisticated laboratory balances to creatine medicines and supplements. Equipment that is inaccurate or precise can lead to negative outcomes, from poor texture and taste in food products to ineffective or harmful substances in supplements and medicines.
The right weighing equipment ensures product consistency, quality and safety. This blog post explains the importance of an anti-vibration table when using sensitive high-precision balances.
What is an anti-vibration table?
An anti-vibration table significantly reduce vibrations and disturbance whilst using highly sensitive laboratory balances. Tables are constructed out of shock-resistant materials such as granite, steel and rubber, and are typically used when conducting precise weighing experiments, testing and scientific analysis in laboratory environments.
What does an anti-vibration table do?
Anti-vibration tables negate vibrations and movement caused by passing vehicles, nearby construction work and drafts. Anti-vibration tables can greatly improve the accuracy of the balance.
Who uses an anti-vibration table?
Anti-vibration tables are used in any laboratory-based environment where precision and accuracy are important:
Professional medical institutions and chemists use these tables with approved balances for accurately measuring chemicals in order to create medicines and supplements.
University science laboratories use anti-vibration equipment with balances for sensitive scientific research, density determination and chemical analysis.
Food testing facilities require highly-precise laboratory balances and anti-vibration equipment in order to accurately determine the optimum weight of food samples.
Types of balance that require an anti-vibration table
Precision balances offer up to 0.01g readabilities and are considered more resilient than higher-precision analytical models. In most cases these balances can be used without an anti-vibration table, but tables are recommended for professional precision balances that offer class I, II and III medical approvals.
An analytical balance features a higher level of precision than standard precision models with up to 0.001g readability. These balances typically come with draft excluders or draft shields. Analytical balances often are used to weigh chemicals, medicines and food samples.
The semi-micro balance offers up to 0.0001g readability and us used for highly sensitive weighing in medical institutions and science labs. Anti-vibration tables are strongly recommended for balances of this calibre.
With up to six decimal place (0.00001g) readability, the micro balance is considered the pinnacle of precision. Micro balances are extremely sensitive, used when high levels of precision and accuracy are critical. An anti-vibration table helps optimise weighing performance when using a microbalance.
