Description
Glass marker pen black is a laboratory writing instrument intended for permanent-style identification of glassware and laboratory apparatus. The black marking medium is suited to glass surfaces and withstands temperatures up to +250 °C, allowing labelled items to remain readable when exposed to elevated process conditions. The ink is waterproof but not wipe-proof, so markings should be shielded from vigorous mechanical wiping if extended durability is needed. Supplied in a pack of 12 pieces, the pens are practical for everyday bench use across research, quality-control and production environments. From manufacturer Witeg, these glass markers support clear assignment of flasks, bottles, fittings and sample vessels during multi-step procedures. The sales unit has a net weight of 0,3 kg and is straightforward to store or share between workstations. Reliable black-on-glass labelling helps maintain sample identity, reduces handling errors and contributes to orderly laboratory documentation and workflow control.
