  • Powder turns red when it comes in contact with acid 
  • Amphomag® turns blue on contact with a base
  • Safely neutralized chemical spills turn green/yellow 

Amphomag® efficiently handles all your spill control needs due to its unique ability to neutralize acids and bases. Amphomag® contains an innovative multi-range pH indicator that further simplifies spill response. When applied to the spill, Amphomagâs® color turns to red for acids and blue for bases. As Amphomag® neutralizes the spill, the color gradually changes to yellow or green. Free liquids in the released materials can easily be controlled and the neutralized material can typically be landfilled. For instance, sulfuric acid is safely rendered to harmless Epson Salt after neutralization.

Some common spill clean up instructions:

How to Clean-Up a Formaldehyde Spill

Formaldehyde is a common chemical used in a variety of products. It can cause respiratory irritation if inhaled, such as coughing, wheezing, and chest pains, and can affect people with asthma, allergies, or other breathing issues more acutely. If formaldehyde comes in contact with the skin, it can cause irritations like dermatitis or even burns. People with frequent exposure to formaldehyde, like some lab techs, become more sensitive to these negative effects. 

If you encounter a formaldehyde spill, first check to see if any has gotten onto you or anyone else around you. Thoroughly wash any formaldehyde off skin with soapy water. Then proceed to clean up the spill using the following directions.

Step 1: Supplies

  • Mask
  • Goggles
  • Gloves
  • Broom
  • Plastic Dustpan
  • Amphomag®
While you may be able to clean the spill without protection if none is available, it again may be better to call in a team to avoid exposure depending on your level of training.

Step 2: Clean Up

  1. Ventilate the area by opening any windows and doors or using a fan.
  1. Put on protective clothing and gear if available before getting near to the spill.
  1. Pour an ample amount of Amphomag® onto the formaldehyde.

Continue to slowly add Amphomag® until it completely absorbs the spill, reducing the harmful vapors and smell in the area.

Step 3: Disposal

The formaldehyde spill is now ready to be disposed of in accordance to your local and state regulations. Use a broom and plastic dust pan to sweep up the Amphomag® and dispose.

How to Clean Up a Hydrochloric Acid Spill

Use extreme care in handling this extremely corrosive, poisonous acid, which can cause severe damage to all body tissues. If a small amount of the acid is spilled, it should immediately be contained and neutralized to prevent harm to anyone or damage to whatever it was spilled on.

When using hydrochloric acid, always wear protective clothing and gear, such as eye goggles and gloves.

Your Chemical Spill Response

Amphomag® is ideal to have in your safety and spill response supplies to neutralize small amounts of chemical spills like hydrochloric acid.
  • Use quickly and safely to treat spills
  • No dangerous side effects
  • No dangerous gas, heating, or splashing

Amphomag® Beats the Competition

Compared to other spill clean-up products, Amphomag® is a one-stop hazardous spill neutralizer. Some spill absorbents, such as OIL-DRI, cannot absorb hydrochloric acid. Amphomag® can, with its unique pH indicator to identify and neutralize most hazardous spills.  
Most chemical spill response steps for laboratories need at least 5 steps in their instructions for use before you can apply a neutralizing agent. Even then, you have to find the right neutralizing agent.

Contain and neutralize any spill quicker with Amphomag® â it is the right product for chemical spills.

Step 2: Clean Up

Follow these 3 easy steps to cleaning up a hydrochloric acid spill using Amphomag®.

  1. Pour Amphomag® slowly and directly onto the hydrochloric acid spill to contain and neutralize.
  2. The Amphomag® will initially turn reddish/pink to indicate that it is an acid and when fully neutralized will turn to a yellow/green color.
  3. If there is any hydrochloric acid remaining anywhere, repeat step 2 until all hydrochloric acid is gone.

Step 3: Disposal

The contained and neutralized spill is now ready to be disposed of as a non-hazardous material.  Use a broom and plastic dust pan to sweep up the Amphomag®.

ION Biosciences IPG-4 AM

Yellow-green fluorescent, potassium (K+) indicator, membrane permeable.
 
Higher K+ affinity than IPG-1 and IPG-2
 
ION Potassium Green – 4 (IPG-4) is a yellow-green fluorescent, intracellular potassium (K+) indicator with Ex/Em: 525 nm/545 nm and a high-sensitivity to detect small changes in K+ concentration. IPG-4 has the highest affinity (Kd = 7 mM) among IPG analogues – IPG-2 (Kd = 18 mM) and IPG-1 (Kd = 50 mM).
ION Biosciences BAPTA AM
 
Non-fluorescent calcium (Ca²+) chelator, membrane permeable.
 
BAPTA AM is a highly selective, intracellular calcium (Ca²+) chelator that is less sensitive to pH fluctuations than EGTA and EDTA. Can be used to modulate the level of intracellular Ca²+.
SBFI K+ SALT
 
Ratiometric sodium (Na+) indicator, membrane impermeable.
 
SBFI is a UV-excitable, ratiometric green indicator for intracellular sodium (Na+) measurements. Ex/Em: 340/505 nm can be used to measure Na+-bound SBFI, and Ex/Em: 380/505 nm can be used to detect Na+-free SBFI. It is ~18X more selective for Na+ over K+. Ratiometry is optimal for imaging applications where quantification of intracellular Na+ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.
SBFI K+ salt is a membrane impermeable form of SBFI that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
