Diamond Marker
Diamond Marker (Product Code: SLE/CL/57) is a pencil-style glass-writing tool whose diamond tip scratches a permanent identification mark onto plain, non-frosted microscope slides. Laboratories at every level, from a basic health-centre lab to a reference centre, use it to number slides before staining, and it is standard lab equipment for college histology and microbiology practicals in India. Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures it in Ambala, India.

Typical Use
Before a smear is spread, write the sample or patient number near one end of the slide with light, steady pressure, as you would with an ordinary pencil. Because the mark is cut into the glass rather than written in ink, it survives staining, alcohol fixation, xylene and immersion oil, and the slide can still be traced months later when it is pulled from storage for review or teaching.
Put the marker away after each session so the tip is not knocked against hard surfaces, and wipe away the fine glass dust after writing so it does not end up under the cover glass. It sits in the slide-preparation drawer alongside other small biology lab equipment in India, such as spreaders, forceps and cover glasses.
Manufacturer
Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer trading as ScienceLab, makes this marker along with the slide-handling and staining items that clinical and teaching labs use every day. See our company profile for more about the company.

Frequently Asked Questions
What comes in one order unit?
The marker is listed as 3 pencils of the same size. Handles may be wood, plastic or aluminium; tell us if you prefer one type and we will confirm what is available.
Will it write on frosted-end slides?
It is intended for non-frosted glass slides. Frosted ends are normally labelled with a lead pencil instead.
Does the mark wash off during staining?
No. The diamond tip scratches the glass surface, so the mark is not removed by stains, alcohol or clearing agents.
Can it be used to cut glass?
It is sold as a marking tool for slide identification, not as a glass cutter.
How should I look after the tip?
Avoid dropping the marker or pressing hard on the glass; store it in a case or drawer where the tip cannot strike other tools.
Can colleges order it in larger quantities?
Yes. We quote for class sets and laboratory stock across India and international markets; send the number of units needed through our contact page.
