Types of balance Analytical balances are designed to measure small masses from around 320g to sub-milligram. They are very sensitive pieces of equipment so need to be treated with care. The main types of laboratory balance are (masses stated are general values only): • Top-pan balance (200g – 0.001g) • Analytical balance (320g – 0.0001g)

different pumps that can be used to fill the product, and the type of pump used depends upon the type of product being filled. The types of pumps include: gravity (solids and liquids) piston (liquids and gases) peristaltic (liquids and gases) The product is generally filled into glass vials; however, different types of containers can be filled
