Nuclease-free Water (not DEPC-treated) has been deionized, filtered into the final bottle, and autoclaved. It is ready to use and requires no preparation, mixing, or autoclaving. This nuclease-free water is rigorously tested for contaminating nonspecific endonuclease

A supersaturated solution contains more solute at a given temperature than is needed to form a saturated solution. Increased temperature usually increases the solubility of solids in liquids. For example, the solubility of glucose at 25 °C is 91 g/100 mL of water. The solubility at 50 °C is 244 g/100 mL of water.

In media with 15% or more salt, the agar may be slow to dissolve. The media may look cloudy, or you may see small, translucent lens-like objects floating in it. Continue boiling until the media is completely clear; this may take longer than 15 minutes

Clear adhesive seals are available for sample visibility and are also provided in opaque colors for light-sensitive materials. Heat seals offer broader chemical and temperature compatibility. Flexible films including paraffin-based Parafilm ® and polyethylene-based DuraSeal ® films can be stretched across vessels of various shapes to prevent evaporation.

Fill the rest of the flask with water. The water will sink to the bottom under the oil and look like little, clear blobs. Add a few drops of food coloring; your choice of color. The food coloring is water-based, so it will also sink and color the water that is now at the bottom of the flask. Break an alka-seltzer tablet into a

The storm glass or chemical weather glass is an instrument proposed as a method for predicting weather. It consists of a special liquid placed inside a sealed transparent glass. The state of crystallization within the liquid was believed to be related to the weather. The inventor is unknown but the device became popular in the 1860s after

8/4/2021 · Empty the bottle and rinse it out a few times to remove all of the soap. When the bottle is clean, dump the water into the sink and refill it with clean water. Dump it again and rinse again. Do this 2 or 3 more times to ensure that the soap is gone.

While adding water to a super water-absorbing polymer and watching it solidify is fascinating, it is not a science fair project — yet. You can create a polymer-themed science fair project by identifying a variable, or something that you can change, in an experiment.
