Move the pipette to the receiving vessel and dispense the liquid by gently pressing the pipette knob to the first stop. After about one second, keep on pressing pipette knob to the second stop. This action will completely empty the tip from the liquid. Afterwards withdraw the tip from the liquid and release the pipette to the ready position.
Photograph of a BioTek MultiFlo FX bulk reagent dispenser. A bulk reagent dispenser (BRD) is a type of commercially available laboratory equipment that dispenses liquid reagents in an automated fashion into microplates, multiwell plates, or microplate-like reservoirs, and specifically have the ability to transfer liquid from a "bulk" (i.e. >1L) source reservoir, but still dispense a ...
Syringe pump. A media dispenser or a culture media dispenser is a device for repeatedly delivering small fixed volumes (typically between 1 ml and 50 ml) of liquid such as a laboratory growth medium like molten agar or caustic or volatile solvents like toluene into a series of receptacles (Petri dishes, test tubes, Fernbach flasks, etc.).
For example, a motorized pipette controller can aid liquid aspiration or dispensing using volumetric pipettes or graduated pipettes; [13] a tablet can interact in real-time with the pipette and guide a user through a protocol; [14] and a pipette station can help to control the pipette tip immersion depth and improve ergonomics.

Reverse pipetting is a technique to dispense a measured quantity of liquid by means of air displacement pipette.The technique is mainly recommended for solutions with a high viscosity or a tendency to foam: [1] as it reduces the risk of splashing, foam or bubble formation.
Positive displacement pipettes are a type of pipette that operates via piston-driven displacement. [1] [2] Unlike an air displacement pipette, which dispenses liquid using an air cushion in the pipette tip, the piston in a positive displacement pipette makes direct contact with the sample, allowing the aspiration force to remain constant.
The thin wrapping portion of the pod which contains the liquid detergent is made from PVA, a dissolvable form of plastic also known as polyvinyl alcohol. This same PVA coating is also used in ...
A burette (also spelled as buret) [1] is a graduated glass tube with a tap at one end, for delivering known volumes of a liquid, especially in titrations. It is a long, graduated glass tube, with a stopcock at its lower end and a tapered capillary tube at the stopcock's outlet. The flow of liquid from the tube to the burette tip is controlled ...
