There are many places where markers and writing instruments are required to stand up to the highest demands. This is particularly true when it comes to labelling and marking in laboratories, where custom-designed products are needed to meet the specific requirements of practical applications. That’s why edding has teamed up with Clariant - the world-renowned chemical company based in Switzerland - to develop its new laboratory markers.  Where other companies have found the challenge too great, the specialists at edding have demonstrated their ability to step up to the mark. The result are two new specialist markers for precise marking on almost any material (especially glass and plastic). Containing ink that won’t rub off, these markers are also TÜV-approved.

Bespoke products for labelling in the laboratory

Whether it be on labels, labware, reaction vessels or microscope slides made of glass or plastic, writing and marking is all part and parcel of the daily routine in all kinds of laboratory. Whether for medical or industrial purposes, the standard of marking demanded by laboratories is very high and requires top-quality, custom products. The new markers developed by edding have exactly the right properties required: the winning feature of the edding 8014 and 8015F laboratory markers is the permanent ink that will not rub off all smooth, transparent materials such as glass or plastic. What’s more, the low-odour ink is also waterproof, non-fade and totally smudge-proof after just three seconds. Markings can be removed from glass surfaces later on using conventional solvents, without leaving any residue.

Two different nibs are available, allowing fine or extra fine writing in black ink that is clearly legible. The stroke width of the edding 8014 laboratory marker is approx. 1 mm. The edding 8015F laboratory marker has a stroke width of 0.75 mm. The ultra-fine nib of the edding 8015F makes marking and labelling possible even when working with a microscope.

The product development team at edding has also taken practical details into consideration: the cap features a special clip which attaches easily to a lab coat pocket so that the markers are always immediately to hand.

Proven quality – a winning formula

Users of these new edding laboratory markers can feel safe in the knowledge that they have been approved by TÜV, the German technical inspection organisation. What’s more, thanks to their excellent performance during practical testing in laboratories, they have been awarded the seal of approval by TÜV Saarland. This certifies that the marker ink is not only highly resistant to wear and abrasion, but can also withstand extremes of temperature. Tests have confirmed heat resistance of up to 500 °C on aluminium and up to 100 °C on other materials. In addition, the writing is still clearly legible even after immersion in liquid nitrogen.

Clariant Masterbatches GmbH, a devision of chemical company Clariant, has already had a chance to test the new laboratory markers extensively in practice. Staff working in its laboratory have reported positive feedback: “Here at Clariant, we use edding laboratory markers to mark samples permanently and accurately – and we are very impressed with the results.”
