Study Notes
Centrifuge Load Unbalance
- An uneven distribution of weight within a centrifuge can lead to vibrations, noise, and potentially damage to the instrument.
Purpose of Balancing a Centrifuge Load
- To ensure the smooth and safe operation of the centrifuge, preventing damage and ensuring accurate separation of samples.
Use of 'Balance' Tubes in Laboratories
- 'Balance' tubes are empty tubes used to balance the centrifuge load when the number of samples is uneven.
Newer Centrifuges and Load Distribution
- Newer centrifuges are equipped with safety mechanisms that can detect an unbalanced load and automatically stop the rotation to prevent harm.
Filter Material in Paper Filtration
- Filter paper, typically made from cellulose fibers, is commonly used for filtering solutions in laboratories.
Reasons for Reduced Use of Paper Filtration
- Modern laboratory environments often utilize more efficient and precise filtration techniques, such as membrane filtration, reducing the reliance on paper filters.
Preparation of Filter Paper for Use
- Traditionally, filter paper was folded into a cone shape and placed within a funnel to facilitate filtration.
