Product Description

1. Overview

Cotton wool and protective aids are basic lab consumables. Degreased cotton is boiled in alkali, rinsed and bleached, which markedly raises its absorbency and wicking action, so it is used for packing, filter backing, absorbing spills and wiping; gauze is soft and breathable, used for padding, covering and basic protection.

The absorbency of degreased cotton comes from the surface treatment: with the waxes and oils removed, water spreads quickly along the fibres for good capillary uptake. Gauze is a loose weave of cotton yarn, breathable and soft, and can be cut to the size needed.

Selection comes down to use and form. Packing and absorbing favour cotton rolls or balls; backing and covering favour gauze rolls or squares. In the lab, keep the packaging clean and dry and reseal after taking what is needed to avoid damp and contamination.

🔬 Types & Features:
Absorbs fast — degreased fibres take up spills quickly.
Clean fibres — sheds little, suited to wiping and backing.
Soft and breathable — loose gauze for covering and padding.
Many forms — cotton rolls, balls, gauze rolls and squares.

2. Key Parameters

Material: degreased cotton wool (pure cotton)
Treatment: alkali boil, degreasing and bleaching
Forms: cotton roll, cotton ball, gauze roll, gauze square
Absorbency: high once degreased
Sizes: 500 g cotton roll, 5 m gauze roll and more
Use: packing, backing, absorbing, wiping, basic protection

3. Material & Workmanship

Degreased cotton is made from natural cotton fibre that is boiled in alkali, rinsed and bleached to remove surface waxes and oils, which markedly raises absorbency. Gauze is woven from cotton yarn and is soft and breathable.

Handling tip: reseal after taking what is needed to keep the packaging clean and dry, and when backing a filter check the cut edges for loose fibres, wrapping in gauze if necessary.

Operation & Maintenance

Operation Guide

The key points with cotton and gauze are keeping them clean and using separate material for separate jobs. Typical steps follow.

Before Use

Choose cotton roll, ball or gauze form to suit the use
Check the packaging is intact and not damp
Prepare a clean work surface
Cut gauze to the size needed
Take cleaning and protective material separately

Procedure

Check the packaging and the labelling before opening
Take only as much cotton or gauze as needed
When packing a vessel, fill it loosely rather than densely
When backing a filter, lay the gauze flat inside the funnel
When absorbing, work from the edge of the spill inward
Reseal promptly so the remainder does not take up moisture
Store cleaning and protective material apart

Cleaning & Care

Seal leftover cotton and gauze and store dry
Keep away from chemicals to avoid odour or contamination
Do not use damp or damaged stock for clean tasks
Use clean scissors when cutting gauze
Dispose of out-of-date stock as general waste

💡 Lab veteran tips: Check before taking — confirm packaging and cleanliness first.
Take only what you need — less waste and less exposure.
Do not pack tight — dense packing slows venting and filtration.
Store apart — keep cleaning and protective material separate.
