The exact buffer concentration for HT511128 is not stated on the website and is considered confidential. The classic textbook formulation for 10% Neutral Buffered Formalin is as follows:
100 ml Formaldehyde, 37-40%
900 ml distilled water
4.0 grams sodium phosphate, monobasic
6.5 grams sodium phosphate, dibasic (anhydrous)
The Specification Sheet states the pH range must be between 6.90 to 7.10. The temperature at which the pH is not measured but should be either 20° or 25°C.
Helpful?
Neutral buffered formalin solutions are particularly sensitive to ambient light. Long term exposure to UV light may result in degradation. This product is packaged in natural opaque plastic. Note that solutions should be tightly closed during storage.
Helpful?
Yes, this product contains Methanol which is included in the formaldehyde starting material. The concentration of methanol in this product is 1.0 - 1.5%.
Helpful?
Is this product HT501128-4L is RNase/nuclease free?
Currently, none of the formalin solutions are nuclease free. Products that are exo or endo nuclease free are typically labeled as suitable for "molecular" use. If no testing is shown as being performed, the products are not claimed to be nuclease free.
Helpful?
Can the product HT501128-4L, Formalin solution, neutral buffered, 10%, be used for immunofluorescence staining?
It is generally expected that if tissues are left in 10% Neutral Buffered Formalin for extended periods, the tissue may not be suitable for immunofluorescence. However, if the tissue spends only a short time in the 10% NBF, it might still be usable for immunofluorescence.
Helpful?
Is there a 10% neutralized buffered formalin stating the osmolality?
None of the formalin solutions are tested for osmolality. Osmolality is significant for live cells, as cells struggle to survive when their surroundings are vastly different from their own, on the other hand formalin is only a fixative solution. Formaldehyde solutions are buffered to prevent the formation of formalin pigment or acid hematin that forms when tissues are fixed at low pH.

What are the differences between products 1004960700 and HT501128?
Products 1004960700 (Formaldehyde solution, 4% buffered) and HT501128 (10% Neutral Buffered formalin) do not have a substantial difference. With HT501128, the formaldehyde used for dilution has a formaldehyde content of 37 to 40%. When the product is diluted 1 to 10 with water, it is referred to as 10% formalin, which has a formaldehyde content of 4% formaldehyde. Both products have the same concentration of formaldehyde in solution.
