Quick Answer: Stainless steel scalpel handles are reusable metal holders for detachable scalpel blades. They are used for dissection in biology labs and for incision practice in medical and nursing skills labs, and can be cleaned and sterilised between uses.
No. 3, No. 4 and Longer Handle Patterns
A stainless steel scalpel handle is the permanent half of a two-part scalpel: the blade is replaced when blunt, while the handle is washed and used again. Handles are identified by number. A No. 3 handle takes the small blades, No. 10 to 15, and is the usual choice for dissection. A No. 4 handle has a larger fitting for blades No. 20 to 25 and suits larger specimens. Longer, slimmer versions such as the No. 7 carry small blades deep into a specimen.
Most handles have a flat, textured grip section, and some carry a millimetre scale etched along one side for measuring structures. The listing does not specify handle numbers, so state them when ordering.
Stainless steel is chosen because it tolerates repeated washing, chemical disinfection and steam sterilisation. That makes these handles suitable for microbiology, surgical skills teaching and any work where instruments must be reprocessed.

Applications
- Dissection of preserved specimens and plant material in school and college biology
- Incision and suturing practice on skin pads and suture arms in medical and nursing skills labs
- Cutting tissue samples in histology and pathology teaching
- Trimming specimen blocks before sectioning
Care & Handling
- Always remove the blade before washing a stainless steel scalpel handle; wash by hand or in an ultrasonic cleaner and dry fully.
- Check the blade slot for burrs or bending; a loose fit lets the blade wobble during a cut.
- Autoclave handles without blades attached and store them in a tray or instrument roll.
Why Choose LabEquip
Colleges, medical and nursing schools buy steel handles once and reorder scalpel blades as needed, which suits departments that run the same practicals every year. For large classes or contaminated work, disposable plastic handles are an alternative. LabEquip lists both in the Biology Lab Products range; send handle numbers and quantities through the contact page.
Frequently Asked Questions
What is the difference between a No. 3 and a No. 4 scalpel handle?
The fitting size. A No. 3 handle takes the smaller blades No. 10 to 15, and a No. 4 takes the larger blades No. 20 to 25. Choose the handle to match the blades you use.
Can stainless steel scalpel handles be autoclaved?
Yes, stainless steel instruments are routinely steam-sterilised. Remove the blade first, clean off all tissue, and dry the handles after the cycle to prevent spotting.
Which handle suits student dissection?
A No. 3 handle with a No. 10 or No. 11 blade covers most school and college dissection. It is light and gives good control for fine cuts.
Why do some handles have a scale on them?
An etched millimetre scale lets the user measure an incision or a structure without picking up a ruler. It is useful in dissection records and skills-lab assessment.
How do I fit a blade to a steel handle?
Hold the blade with a needle holder, line up its slot with the groove on the handle and slide it on until it clicks into place. Remove it the same way, lifting the heel slightly first.
Can the same handle be used for dissection and microbiology?
Yes, provided it is cleaned and sterilised between uses. Many labs mark separate handles for microbiology to keep contaminated and clean work apart.
