"Bag" - what is it, definition of the term
A sack is a flexible enclosure, typically fabricated from cloth, leather, polymer or woven fibres, designed to hold objects or substances; it features an opening sealed by drawstrings, zippers, or seams, and may be shaped to conform to the contents, providing containment, transport, and protection. In entomological practice, such enclosures are employed to collect, store, or transport small arthropods such as ticks, bugs, lice, and fleas, allowing specimens to remain isolated while preserving their integrity.
Detailed information
A durable, sealable pouch provides an effective solution for collecting and transporting arthropod specimens such as ticks, bedbugs, lice, and fleas. Polypropylene or nylon fabrics resist puncture and moisture, preventing escape and degradation of specimens during fieldwork or laboratory analysis.
Key characteristics of an optimal container include:
- Secure closure – zip-lock, Velcro, or heat-sealed seams eliminate gaps that could allow insects to exit.
- Transparent panels – allow visual inspection without opening the enclosure, reducing handling risk.
- Chemical resistance – compatibility with ethanol, formalin, or other preservative solutions ensures specimen integrity.
- Size variety – small sachets for individual insects, larger sacks for bulk collections, accommodate different sample volumes.
When deploying the device in the field, follow these steps:
- Wear disposable gloves to avoid cross‑contamination.
- Capture the target arthropod with forceps or a fine mesh net.
- Transfer the specimen directly into the pouch, avoiding contact with the interior surface.
- Seal the enclosure immediately, then label with species, date, location, and collector name.
For long‑term storage, keep sealed containers in a cool, dark environment. Refrigeration slows degradation, while a temperature‑controlled cabinet prevents condensation that could compromise the seal. Periodic inspection confirms that the closure remains intact and that no moisture has accumulated.
Disposal procedures require decontamination to prevent accidental release. Submerge sealed pouches in a 10 % bleach solution for at least 30 minutes, then incinerate or discard according to institutional biosafety guidelines. Documentation of the disposal process satisfies regulatory compliance and ensures traceability.
Overall, a robust, resealable sack enhances safety, preserves specimen quality, and streamlines workflow for researchers handling tick, bug, louse, and flea samples.
