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.
