Biskanten ^TM 纯化琼脂（Purified Agar）

琼脂,学名琼胶,英文名（agar）,又名洋菜(agar-agar),冻粉,燕菜精,洋粉,寒天，是由海藻中提取的多糖体，是目前世界上用途最广泛的海藻胶之一。琼脂为亲水性胶体，外观为浅黄色或类似白色的粉状或条状产品。它不溶于冷水而溶于沸水，在1.5%时为澄清的液体，冷却到34~43℃时形成较坚硬的凝胶，再加热到85℃以下时不融化。所以它是配制固体培养基的最好凝固剂。用琼脂配制的固体培养基，可用以进行高温培养而不熔化，在凝固之前接种时，也不致将培养物烫死。因此，琼脂是制备各种生物培养基中应用最广泛的一种凝固剂。常用于微生物培养，组织培养，生物膜材料等。本公司生产的琼脂糖凝胶强度高、弹性好、硫酸根低、透明度高等优点。琼脂经过纯化处理，可以制备纯化琼脂。具有更好的透明度和很低的电渗。可用于高端微生物培养，组织培养。

参考指标：

Agar is polysaccharide extracted from seaweed, which is one of the worlds most widely used seaweed gel. Agar is hydrophilic colloid, white or similar white powder or strip products. It is insoluble in cold water and soluble in boiling water which is clear liquid, when cooled to 34 to 43 ℃ to form a solid gel, and it cannot melt when heated below 85 ℃. So it is one of the best curing agent for solid medium. Agar solid culture medium, can be used for high temperature culture without melting, vaccination after solidification, also from cultures burned to death. Therefore, Agar is the most widely used in the preparation of various biological medium，it also used in mold material. The agar produced in our company has high gel strength, good elasticity, low sulfate, low EEO and high transparency. Purified agar has Low sulphate, used for high-end Tissue culture.
