Pipettes are used to transfer or measure set volumes of liquid, ranging from 0.1 µL to 10 mL. Start by choosing a displacement method: Air-displacement pipettes are often recommended for aqueous samples since there is always an air cushion (dead volume) between the sample and the piston. Samples that are viscous, radioactive, corrosive, or volatile tend to require a positive-displacement pipette, which has a disposable piston and direct piston–sample contact. No air cushion means more accurate pipetting of high-density samples. Next, choose manual versus electronic operation. Manual pipettors tend to be very durable and easily maintained, while electronic pipettors have the advantage of increased accuracy, reduced force, and a lower risk of repetitive stress injuries. Repeating electronic pipets are useful in biochemistry, microbiology, and immunology. Single-channel pipettes are workhorses in liquid handling; multichannel pipettes are common in PCR and ELISA applications, with the number of channels ranging from 4 to 64.

Osmometers are used to measure the osmolality of aqueous samples. The freezing point depression method is the most commonly used method in laboratories around the world.

Laboratory incubators and ovens find extensive application in hospitals, and in biology and microbiology labs. Incubators are used for culturing, heating, and incubation of reagents, samples and media where warming and steady temperature are required. Incubators are broadly used for a number of applications such as bacteriology, diagnostic protocols for water, food and beverage testing, clinical, pharmaceutical and biotech testing, and so on. Ovens are used for dry heat sterilization, polymerizing plastics, evaporation, product age acceleration, annealing, and for drying glassware and samples. They are available in different models with power ratings of 230 V and 115 V.
