Our vannas scissors are specialized spring scissors designed for precision cutting and often used by scientific researchers. They are named after the Swedish scientist Gunnar Vannas who invented them in the 1940s. Compared with other spring scissors, vannas scissors are distinguished by their delicate, thin, sharp tips. The slender, pointed tips allows for precise cutting with minimal damage to surrounding tissues. Manufactured with surgical grade stainless steel, these scissors are durable and resistant to corrosion.

Details

WPI's Vannas Spring Scissors are precision spring-action micro-dissection scissors, 8cm long with 5mm blades and 0.1mm tips built for fine, repetitive cutting with minimal tissue damage in neuroscience, cell biology, and microsurgery. These 8cm scissors have 5mm blades and 0.1mm tips, available in straight, curved, or angled configurations, each in standard or German surgical-grade stainless steel. The spring-action handle returns the blades to open position automatically after every cut, and the slender, pointed tips allow precise cutting with minimal damage to surrounding tissue.

Features

8cm (3.5") overall length
5mm blades, 0.1mm tips
Spring-action handle returns the blades to open position automatically after every cut
Surgical-grade stainless steel, standard or German grade
Straight, curved, or angled tip configurations

Applications

Vannas scissors are a popular choice for researchers in fields that require precision cutting, such as biology, neuroscience, and microsurgery. Common applications include:

Microdissection of small organisms, such as insects or embryos
Preparation of small tissue samples for histological analysis
Cutting thin sections of cells/tissues for viewing under a microscope
Preparation of brain slices for electrophysiological studies
Dissection of small neural circuits
Preparation of brain tissue for imaging or analysis

Options

Order code	Tip shape	Details
14003	Straight, Standard
14003-G	Straight, German
14122	Curved, Standard
14122-G	Curved, German
500260	Angled, Standard	45° angled to side
500260-G	Angled, German	45° angled to side
501790	Angled up, Standard	Angled up

Which variant do I need?

Straight (14003/14003-G): General microdissection, cutting in a straight line under direct view
Curved (14122/14122-G): Improved visibility around the cutting point, which is useful when you need to see past the blade tip
Angled to the side, 45° (500260/500260-G): Reaching tissue at an angle without repositioning the instrument.
Angled up (501790): Cutting upward or away from the viewing axis in confined surgical fields.

Standard vs. German Stainless Steel

German steel is regarded as a harder, more wear-resistant grade, suitable for labs doing high-frequency repeated microdissection. Standard stainless steel is the typical option for general use.

Standard Stainless Steel	German Stainless Steel
Good for general use	Harder edge, holds up under repeated use
General or occasional microdissection	High-frequency, repeated micro-dissection

FAQs

What are Vannas spring scissors used for?

Precision microdissection in neuroscience, cell biology, and microsurgery, including dissecting small organisms (insects, embryos), preparing tissue samples for histology, cutting thin cell/tissue sections, preparing brain slices for electrophysiology, and dissecting small neural circuits.

What's the difference between straight, curved, and angled Vannas scissors?

Straight is best for general dissection under direct view. Curved improves visibility around the cutting point. Angled (side or up) lets you reach tissue without repositioning the instrument. See the selection guide above for the full breakdown.

Is German steel worth the price difference over standard stainless?

German steel is generally regarded as a harder, more wear-resistant grade, making it the better fit for labs doing high-frequency, repeated microdissection. Standard stainless steel is the typical option for general or lower-frequency use.
