Frequently asked questions
Is the ink resistant to harsh laboratory chemicals?
Yes, the VWR Resistant Marker features a specialized, professional-grade ink formula designed to be chemical-resistant. It is specifically tested to remain permanent and legible even when exposed to:
- Formalin
- Xylene
- Water (it is completely waterproof)
- Smear-causing environmental conditions
Can I use this for labeling histology slides?
Absolutely. This marker is engineered specifically for histology and pathology laboratory workflows. It is optimized for marking frosted microscope slides and standard tissue embedding cassettes, ensuring your sample identifiers remain intact throughout the processing and staining stages.
Does it provide precise control for small labels?
Yes, the marker is equipped with an ultrafine tip, which allows for high-precision, clear, and legible writing. This is critical for laboratory professionals who need to include accurate, detailed information on small surfaces like tissue cassettes.
Is this ink permanent on all surfaces?
It is important to note that this marker is formulated for porous or frosted surfaces only. For the best performance and permanence, it should be used on:
- Frosted microscope slides
- Tissue embedding cassettes
Note: It is not suitable for writing on smooth, non-absorbent, or glass-like surfaces.
Is the ink scent distracting for daily use?
No, the marker is designed for clinical and research environments, so the ink formula is odorless, making it comfortable for extended use in laboratory settings.
Will the markings smear during tissue processing?
The ink is explicitly smearproof. Once applied to the appropriate frosted surface, it is designed to withstand the rigorous demands of histology processing, ensuring your diagnostic records remain professional and accurate.
How do I keep the tip from drying out?
To ensure the longevity of the ultrafine tip and the quality of the ink flow, this marker comes with a secure Tip Cap. We recommend keeping the cap firmly closed when the marker is not in active use to maintain the integrity of the ink.
Is this a professional-grade laboratory tool?
Yes, this is a VWR International product, specifically built for high-reliability applications in clinical research, pathology departments, and diagnostic facilities.
Does the ink color fade over time?
The ink is designed for permanence. Because it is resistant to chemicals like formalin and xylene, it maintains its deep black color, ensuring that critical specimen labels do not fade or degrade during long-term storage or processing.
Are there any specific surface requirements?
For optimal results, apply the marker only to frosted or porous surfaces. Using the marker on smooth or non-absorbent surfaces will prevent the ink from adhering correctly, potentially resulting in smearing or lack of permanence.
