  • When should I use DietGels®?

    DietGel® products are soft diet formulation with carbohydrate, fat protein, and fortified with a mineral and vitamin mix (with the exception of DietGel Recovery, which only contains mineral mix). They are a superior alternative to mash diets, that can be used as the sole source of nutrition for up to 7 days. reducing time and labor costs.  However, customers have used the product as a sole source of nutrition for up to 3 months with no issues. Please consult with your nutritionist for long term use. DietGel products are designed to provide compromised rodents a palatable source of hydration and energy and are an excellent solution for supplemental hydration for:

    • Breeding and weaning of pups 
    • Post-surgical support 
    • Neurologically compromised rodents 
    • EAE models, Transgenic Mice 
    • Shipping
  • What is the best way to store DietGel products?

    Unopened DietGel can be stored at room temperature and does not require special handling. Shelf life for unopened DietGel is 18 months.

    Once opened (provided the gel has not been contaminated) ClearH2O products can be stored either at room temperature or at 4°C in a sealed bag/container to prevent the product from drying out for approximately 2 weeks

  • Why does DietGel sometimes have white or brown specs?

    Non-soluble ingredients are sometimes visible in DietGel, showing up as white to brown specs or clumps. The non-soluble ingredients do not affect the nutritional integrity of the product, making it 100% safe to use for your research animal.

  • Why does the color of DietGel vary from case to case?

    Color variation occurs during our sterilization process. When DietGel products are produced the color is a milky white. The product is then sterilized. The irradiation process changes the product color from a milky white to a caramel color. Product position within the sterilization chamber results in color variation. All of the product is 100% sterile and safe to use.

  • What is the difference between DietGel 76A, DietGel 31M and DietGel Recovery?

    DietGel 31M is a nutritionally complete soft diet combining both nutrition and hydration.  It is modeled on the NIH 31 maintenance formula. Made with purified ingredients, including sunflower seeds, the soft texture is ideal for compromised animals.

    DietGel 76A is a soft diet with a full complement of carbohydrate, fat and protein. It is fortified with both AIN mineral and vitamin mix. A superior alternative to mash diet, DietGel 76A can be used as the sole source of nutrition and hydration for long periods of time, reducing time and labor costs. Carbohydrates, fat and smaller amounts of protein provide the source of calories in 76A.

    DietGel Recovery is a nutrient fortified hydration gel designed to provide compromised rodents a palatable source of hydration and energy and is an excellent solution for:

    • Breeding and weaning of pups
    • Post-surgical support
    • Neurologically compromised rodents
    • EAE models
    • Transgenic Mice
    • Shipping

    Because the formula does not contain vitamins and has lower levels of protein than standard diets, it is not recommended as a sole source of nutrition for long periods of time.
