Laboratory forceps are small tools used to pick up objects that are too small to be easily manipulated by human fingers. Most likely, the word is derived from forceps, forceps or scissor pliers that have been used to grab or hold hot objects since the beginning of recorded history.

In a scientific or medical context, they are usually referred to as forceps. The grippers use two third-class levers connected at one fixed end (the fulcrum of each lever), with the grippers at the others. People usually use forceps mainly for tasks such as plucking hair from the face or eyebrows, often with the term eyebrow forceps.

Other uses that are normally given to laboratory forceps are used as a utensil to handle tiny objects, including, for example, small electronic parts, especially surface-mounted, and tiny mechanical parts for prototypes and exact mechanisms.

Stamp collectors use forceps (stamp forceps) to manipulate postage stamps that, while large enough to pick up by hand, could be damaged by handling; the jaws of the stamp tweezers are smooth.

An example of a specialized use is the selection of gold flakes in the collection of gold. The tongs are used in the kitchen to present food to remove the bones to the fish meat in a process called as boning.

Tweezers come in a variety of tip shapes and sizes. Blunt-tipped tweezers have a rounded end that can be used when a pointed object can get tangled, when handling cotton swabs, for example. The flat-tipped tweezers, illustrated on the right, have an angled tip that can be used to remove splinters. Some tweezers have a long needle-shaped tip that can be useful for reaching small cracks.

Triangular-tipped tweezers have larger and wider tips, useful for grasping larger objects. There are also tweezers with curved tips, sometimes called bent tweezers. Microtweezers have an extremely small, pointed tip used to manipulate tiny electronic components and the like.

There are two common forms of construction for tweezers: two angled or fused pieces of metal, or one piece of metal bent in half. The bent caliper is cheaper to manufacture, but provides a weaker grip. The fused caliper is more expensive, but allows for a stronger grip. The width between the tips of the tweezers when no force is applied also affects the power of the grip.

Cross-locking tweezers (also known as reverse action tweezers or self-closing tweezers) work in the opposite way to normal tweezers. The cross-locking clamps open when tightened and close when released, gripping the item without any effort from the user's fingers.

The original forceps for mechanical gripping have given rise to a series of tools with a similar purpose or action but not dependent on mechanical pressure-

The optical forceps

They use light to control microscopic objects as tiny as a single atom. The transfer of momentum from a focused laser beam is capable of trapping small particles. In the biological sciences, these instruments have been used to apply forces in the Newton peak range and to measure displacements in the nm range of objects ranging in size from 10 nm to more than 100 mm.

Magnetic forceps

They use magnetic forces to manipulate individual molecules (such as DNA) through paramagnetic interactions. In practice, it is a series of magnetic traps designed to manipulate individual biomolecules and measure the ultra-small forces that affect their behavior.

The electric forceps

They emit an electrical signal through the tip, designed for hair removal by damaging the hair roots to prevent new hair from growing from the same root.

The vacuum forceps

They use differences in atmospheric pressure to grab items from 100 micrometers in size to parts weighing several pounds. The unique tips for vacuum tweezers are designed to handle a wide variety of objects, such as:
* Stamps.
* Coins.
* Surface mount electronics.
* Biological material.
* Optics.

They can be used to handle parts that are so small that conventional mechanical tweezers (forceps) can damage or drop the parts.

The molecular tweezers

They are non-cyclic host molecules that have two arms capable of joining host molecules by a non-covalent bond.

Hot or soldering tweezers

They combine the compressive action of mechanical tweezers with heating to grip small surface-mounted electronic devices while at the same time heating them for soldering or desoldering.

The tweezers probes

They are a pair of electrical test probes fixed to a clamp mechanism to measure voltages or other parameters of electronic circuits between pins very close to each other.

Integrated tweezers with an electronic measuring device

Used for the evaluation of electrical parameters of small electronic components.

The carbon nano-tweezers

They have been manufactured by depositing MWNT beams on insulated electrodes deposited on tempered glass micropipettes. Those nanotube packages can be manipulated mechanically by electricity and can be used to manipulate and transfer micro and nanostructures. The nanotube beams used for the tweezers have a diameter of about 50 nm and a length of 2 µm. Under electrical polarization, two close sets of bundles are attracted and can be used as nanoscale tweezers.

Other uses of the same principle are called tweezers; although such terms are not necessarily used broadly, their meaning is clear to people in the relevant field.
