The serological pipette is frequently used in the laboratory for transferring milliliter volumes of liquid, from less than 1 ml to up to 50 ml. The pipettes can be sterile, plastic, and disposable or sterilizable, glass and reusable. Both kinds of pipettes use a pipet-aid, for the aspiration and dispensation of liquids. Different sizes of pipettes can be used with the same pipet-aid for a variety of experimental assays. For example, serological pipettes are useful for mixing chemical solutions...

Odorant-induced Responses Recorded from Olfactory Receptor Neurons using the Suction Pipette Technique

Cited by 13 •
2012
Olfactory receptor neurons (ORNs) convert odor signals first into a receptor current that in turn triggers action potentials that are conveyed to second order neurons in the olfactory bulb. Here we describe the suction pipette technique to record simultaneously the odorant-induced receptor current and action potentials from mouse ORNs.
FAQs
Tip size helps balance stimulation localization against tissue impact. A tip pulled to the required size supports a localized electric field while helping limit tissue damage. The appropriate configuration therefore contributes to both experimental control and tissue preservation, which is important when stimulating individual neurons or defined regions of neural tissue.
The conductive solution provides the pathway through which applied current travels inside the glass pipette. When the pipette is connected to a stimulator, this current produces the intended localized electric field near the neural target. Consistent filling is therefore part of maintaining controlled electrical delivery during recordings and stimulation experiments.
Preparation quality influences whether stimulation remains stable and whether unwanted electrical artifacts interfere with recordings. Appropriate tip formation, conductive filling, and connection to the stimulator help keep current delivery controlled. Reducing such artifacts makes recorded responses easier to interpret when examining synaptic transmission, neuronal excitability, or circuit connectivity.
The workflow includes pulling a glass micropipette to the required tip size, filling it with a conductive solution, and connecting it to a stimulator. These steps establish the physical route for current delivery and prepare the pipette for localized stimulation. Careful preparation also supports stable operation and helps limit tissue damage.
Researchers use this approach when they need to apply controlled electrical input to neural tissue or an individual neuron. It supports experiments examining synaptic transmission, circuit connectivity, and neuronal excitability. The method is also relevant when investigators study how neural systems respond to patterned electrical input in brain slices or other preparations.
A well-prepared pipette can help investigators relate applied electrical stimulation to responses associated with synaptic transmission, circuit connectivity, and neuronal excitability. In brain slices and other experimental preparations, it also supports studies of patterned input. Stable stimulation and reduced recording artifacts improve the interpretability of these neural responses.
