FAQ

  • What is the minimum order quantity (MOQ)? How about the price?

    ·MOQ: For standard products, our bagged MOQ is usually 500 kilograms. For customized specifications or high-purity agarose, the MOQ may be higher.
    ·Price: The price is affected by many factors, including the strength grade of gel, source of raw materials, purity (food grade/medium grade/agarose), purchase quantity, packaging specification, and international freight/exchange rate fluctuations. For example, the price of high-strength cauliflower agar is usually higher than that of ordinary Gracilaria agar. Please let us know your specific needs and applications, and we will provide you with the most competitive quotation.

  • What is the solution temperature and gel temperature of the product?

     These are the key process parameters for agar.
    ·Dissolving temperature: It needs to be heated to 90-100 ℃ and maintained for several minutes to fully dissolve in water.
    ·Gel temperature: gel is formed when the solution is cooled to 35-42 ℃. This "temperature lag" (that is, the sol temperature is much higher than the gel temperature) is its unique advantage, which makes it stable at room temperature.
    ·(Note: The specific temperature point may vary slightly depending on the product model and solution system, and we will provide a product specific data sheet (TDS).

  • What is the gel strength of agar? What units are usually used to represent?

    The strength of gel is the core index of our products, and the unit is g/cm2. It usually refers to the maximum weight of gel formed at 1.5% concentration and 20 ℃, whose surface can withstand without puncture under standard conditions. We offer products of different strength levels, such as:
    ·Low strength: 300-500 g/cm ⊃2; (suitable for foods that require a soft texture, such as pudding)
    ·Medium strength: 600-800 g/cm ⊃2; (universal grade, suitable for jelly, candy, dairy products)
    ·High strength: 900-1200 g/cm ⊃2; or higher (suitable for microbial culture media, high-end lamb soup, special industrial applications)
    ·(Please provide specific range based on actual product parameters)

  • What is the source of your agar? (For example: Gracilaria, Caryophylla, Gracilaria?)

    We mainly supply agar made from Gracilaria and Caryophyllum as raw materials. Gracilaria agar has a high yield and cost-effectiveness, making it suitable for most food and industrial applications; The strength and transparency of the gel of cauliflower agar are better, and it is suitable for high-end food and microbial culture media with higher quality requirements. We can recommend the most economical and efficient types of raw materials based on your specific application.

  • What is the shortest delivery time for custom-specification agar?

    Relying on our automated production line with an annual capacity of over 10,000 tons, regular custom orders can be completed within 7 working days.  With our global logistics network covering 50 countries, urgent orders can be delivered within 48 hours via air freight.

  • Does clumping during agar storage affect its quality?

    Slight clumping is a normal physical phenomenon. Because our product has a moisture content of ≤8%, it can be stored for 24 months under sealed conditions in a dry environment. Sieving before use will restore uniform particles.

  • How to deal with blurred bands in agar gel electrophoresis?

    Our molecular biology-grade agarose undergoes nano-level purification treatment, achieving a gel pore size uniformity of 98%. We recommend using a standard buffer solution and controlling the electrophoresis voltage within the range of 100-150V.

  • What could be the reason for microbial contamination in laboratory culture media agar?

    Our products are ISO 22000 and FDA certified, and packaged using sterile production lines.  Moisture-proof and antibacterial composite film is used during transportation. If contamination occurs, please check your laboratory operating environment or storage conditions.

  • How to solve the problem of insufficient dissolution of agar in food processing?

    We recommend using 80-90℃ hot water and stirring thoroughly to dissolve it. Our high-purity agar has fewer impurities, resulting in a 30% faster dissolution rate compared to ordinary products, thus avoiding clumping.
