We believe that scientists should spend their time analyzing results,
not doing repetitive tissue cutting and slide cataloging.
The HistoWiz platform combines
cutting-edge technology, optimized workflows and a dedicated, expert team
to bring you the most efficient histology service for experimental
pathology specimens. From the moment we receive your samples to the
instant you can view your results online, we have one goal: to get you
the highest quality results in the shortest time at the most competitive
Our website allows instant remote access, collaboration, and analysis of
virtual slides on any PC, Mac or mobile device without the need to
download additional software or gigabyte-sized files. Try it out—explore

Fedex/UPS Ground (preferred method of shipment for NY, NJ, CT, MA, PA, MD, DE):
Send tissues either in 10% Neutral Buffered Formalin (NBF) or 70% ethanol
Fedex/UPS Express (domestic and international):
Send tissues in 10% NBF
For IHC, fix tissues in 10% NBF for 24-48 hrs at room temperature and then
directly transfer to 70% ethanol before shipping. Storage in 70% alcohol
more than 1-2 days is not recommended.
For H&E staining, samples can be stored in 10% NBF up to several months
at room temperature.
The volume of fixative must be 20x over the sample volume and the tissue must
be completely immersed in the solution. It is recommended to cut large tissues
into thinner slices of 2-5mm to allow better fixation.
If samples are stored in 10% NBF for an extended period, check the clarity
of the formalin solution regularly. If it becomes cloudy, change to fresh 10% NBF.
Sample Harvest and Shipping
After necropsy, submerge each wet tissue specimen in a 15ml or 50ml Falcon
tube filled with 10% NBF, seal cap tightly, put tubes into a zip-lock bag
and ship in a durable box.
The tissues should be shipped at room temperature.
Tubes or cassettes must be labeled with pencil or laboratory grade markers/labels
(resistant to formalin, ethanol, isopropanol and xylene).
Glass slides for scanning can be stored in a slide box and shipped in a padded
envelope or box.
Samples can be shipped in bulk all at once and stored at HistoWiz until the
study is completed.
You can order pre-filled histology containers with 10% NBF from
These preservatives are exempt and not regulated by Department of Transportation.
DO NOT use the "Dangerous Goods in Excepted Quantities" statement on
any shipping documents.
The primary container (tube, specimen vial) must not be more than
90% full. Secondary packaging (i.e. zip-lock bag) must be leak proof.
No other hazardous material is present, and specimens do not contain
any infectious materials.
Outer packaging must be wood, fiber board, styrofoam or other equally
