Scalpels, Fixed

Quick Answer: Fixed blade scalpels are one-piece dissecting knives in which the blade and handle are made together, with no detachable blade. They are used in school and college dissection sets for cutting soft tissue and plant material.

Specifications

One-Piece Scalpels versus Detachable Blades

In a fixed scalpel the cutting blade and handle form one piece, usually with a short curved edge. Because nothing detaches, students never have to fit or remove a blade, and there are no loose blades to count at the end of a practical. This is the traditional scalpel found in many student dissecting sets.

The trade-off is sharpness. A detachable blade is replaced the moment it dulls, whereas a fixed scalpel has to be resharpened on a fine oilstone. Teachers who look after their sets keep the edges honed, and for most school dissection of flowers, fruits and preserved specimens a well-kept fixed scalpel is entirely adequate.

For finer or high-volume work, stainless steel handles with replaceable blades may be more practical. The listing does not specify the blade shape or length of these fixed scalpels.

Applications

• Longitudinal sections of flowers and fruits in botany practicals
• Cutting through the body wall of preserved specimens in zoology dissection
• Preparing potato or carrot pieces used as supports for section cutting
• Replacing lost or worn scalpels in existing student dissecting sets

Care & Handling

• Wash and dry the fixed scalpel after each class; one-piece steel instruments rust at the blade root if stored damp.
• Hone the edge on a fine oilstone with light, even strokes at a consistent angle.
• Store with a blade guard or in a slotted case so the edge does not strike other instruments.
• Carry the scalpel with the blade pointing down and pass it handle first.

Why Choose LabEquip

Schools most often buy fixed scalpels to complete or replace items in a student dissecting set, since they match the one-piece instruments already in those kits. LabEquip lists them in the Biology Lab Products range; send your quantity via the contact page.

Frequently Asked Questions

What is the advantage of a fixed scalpel over a detachable blade?

There is no blade to fit, remove or lose, which makes it simpler and safer for younger students. It also suits kits that are issued and collected every lesson.

How do I sharpen a fixed scalpel?

Use a fine oilstone with a few drops of oil. Hold the blade at a low, constant angle and draw it along the stone, working both sides evenly, then wipe it clean and test on paper.

Is a fixed scalpel as sharp as a disposable blade?

A new disposable blade is usually sharper. A fixed scalpel kept honed is sharp enough for school dissection of plants and preserved specimens.

Can fixed scalpels be sterilised?

All-steel fixed scalpels can generally be steam sterilised or disinfected like other steel instruments. Check the handle material first if it is not metal.

Why do dissecting sets still include fixed scalpels?

They are sturdy, have no small parts, and can be resharpened many times. For a set issued to many students, that simplicity is useful.

What should I do if the tip of a fixed scalpel breaks?

A broken tip can sometimes be reground on a stone into a new point. If the blade is cracked or bent, withdraw the scalpel, because it can snap during use.
