Tape dispensers are available in a number of formats, including formats that can accommodate multiple rolls of tape and formats with writing platforms. A variety of tape sizes can be accommodated. Hand-held tape dispensers are available.

Tape dispensers make it easier to cut label tape and to add information to the tape to properly identify laboratory tubes and containers and their contents.

The proper labeling of containers and vessels, solutions, and other materials is key to good laboratory practice. Unlabeled or improperly labeled containers can result in misuse, ruin experiments, and create hazards for users.

Tape dispensers are available in several varieties depending on their intended use.

• Handheld tape dispensers are portable, have a cutting edge, and typically hold a single roll of label or sealing tape.
• Benchtop tape dispensers may be weighted to allow the tape to be more easily pulled with one hand.
• Single- or multiple-roll benchtop tape dispensers may include a flat writing surface to make it easier to write on the tape.
• Dual- or multiple-roll benchtop tape dispensers hold more than one roll or color of tape. These are useful when color-coded labels are used.

Label and sealing tapes have a range of inside (core) and outside diameters, and some tape dispensers can accommodate more than one size of tape width and roll size.

Tape dispensers may be plastic, metal, or made from a combination of materials.
