Flower Cutter

Quick Answer: A flower cutter is a small hand-held cutting tool with two short blades closed by squeezing the handles, used to cut flower stems, leaves and soft green shoots cleanly. In a biology lab the flower cutter is used to collect fresh plant material for dissection, mounting and transpiration experiments.

Clean Cuts on Soft Plant Material

The blades of a flower cutter are short, so the tool closes right where the stem is held, which gives far more control than ordinary scissors when working among leaves and buds. Most cutters of this kind use a bypass action, in which one curved blade slides past the other and leaves a clean slice rather than a crushed end. Anvil-type cutters, where one blade presses onto a flat jaw, are stronger on dry woody stems but tend to bruise soft tissue. The blade pattern of this model can be confirmed before ordering.

A clean cut matters in biology practicals. When a leafy shoot is prepared for a potometer, the stem is cut under water so that no air enters the xylem; a ragged or crushed end takes up water poorly and the bubble in the capillary tube barely moves. Flowers taken for the study of floral parts, such as hibiscus or mustard, also keep their shape better when the stalk is cut rather than torn.

The cutter is sized for green material. Thick woody branches, wire and hard plastic ties spread the blades and blunt the edge; wire belongs to a side cutting plier, and branches to loppers or a pruning saw.

Specifications

Applications

• Collecting fresh flowers for dissecting and labelling sepals, petals, stamens and carpels
• Cutting leafy shoots under water for potometer and transpiration-rate experiments
• Gathering leaves and small twigs for herbarium sheets and identification keys
• Trimming plants in a school garden, greenhouse or plant-growth investigation

Care & Handling

• Wipe sap off the blades after use; dried sap makes the blades stick and traps dirt.
• In disease or growth studies, wipe the blades with an alcohol swab between plants so infection is not carried from pot to pot.
• Put a drop of light oil on the pivot now and then, and keep the catch closed when the cutter is stored or carried.
• Pass the cutter to students handles first with the blades closed.

Why Choose LabEquip

Frequently Asked Questions

What is the difference between bypass and anvil blades?

Bypass blades pass each other like scissors and give a clean slice that suits living stems. Anvil blades press a single edge onto a flat jaw; they cut dry, woody material with less effort but crush soft stems. For fresh flowers and green shoots, bypass cutting is preferred.

Why should the shoot be cut under water for a potometer?

Cutting in air lets air enter the open xylem vessels, and the air lock stops water being drawn up the stem. Cutting under water and fitting the shoot into the potometer while still submerged keeps the water column continuous, so the bubble moves at a measurable rate.

Can this cutter handle woody branches?

Only thin, soft twigs. Thicker branches and hard dry wood force the blades apart and dull the edge. Use loppers or a pruning saw for those.

How do I clean sticky sap off the blades?

Wipe the blades straight after use with a damp cloth, then with a little alcohol if sap has dried on. Dry the blades and oil the pivot lightly so it keeps moving freely.

Can the cutter spread plant disease between samples?

Yes. Sap left on the blades can carry fungal spores, bacteria or viruses to the next plant. In growth or disease studies, wipe the blades with an alcohol swab between plants or treatment groups.

Is the cutter suitable for school students?

With supervision, yes. Students should close the catch when not cutting, keep the fingers of the holding hand away from the blades and cut away from the body. Stems for younger pupils can be cut by the teacher.
