    Description

    UltraCruz® Fine Tip Lab Markers can be used for a wide variety of laboratory marking, labeling, or addressing tasks. Markers are suitable for industrial, biomedical, research, and educational laboratories for marking small lab samples, slides, beakers, sample bags, freezer boxes, and more. Lab Markers can be used to write on glass, film, plastic, metal, porcelain, wood, rubber, and paper. Markers contain permanent ink that is water resistant (all markers) and alcohol resistant (sc-553351 and sc-553352 only). The durable fine tip and generous ink supply provide a long product life. Markers are available in green or black ink that dries quickly for immediate handling of labware. An airtight cap prevents the marker from drying out. UltraCruz® Lab Markers are comparable to Sharpie® Marker Pens.

    Is the marker alcohol resistant?

    Asked by: Laport
    Thank you for your question. These markers contain permanent ink that is water resistant but not alcohol resistant.

    Rated 1 out of 5 by from They're different nowNo longer ethanol resistant. Big downgrade in quality. They were great years ago.

    Rated 5 out of 5 by from Ethanol resistantGood for cell culture work, ethanol resistant. The tip is not very fine (not good if you need to write a lot in eppendorf tubes), but it is good for plates and falcon tubes.

    Rated 5 out of 5 by from Bang for your buckThese are the cheapest markers that are alcohol resistant i've been able to find across the internet. The black ones work perfectly fine but decided to try the red ones and was not disappointed. Most other places sell 4-6 pens for the price you pay for 10 of these.

    Rated 5 out of 5 by from Works as described!Was one of the best ethanol resistance marker we bought for the lab in a while.

    Rated 4 out of 5 by from Good markerBought these to label microscope slides - the color does tend to run off when staining slides (mostly from solvent fixing solutions) but enough color stays to identify the slide.

    Rated 4 out of 5 by from Great lab markers!Finer point than standard permanent markers which is nice for writing on small areas. Fades a bit in fixing solution for slides (alcohols), but stays on the slide enough to still be able to read it.
