A simple, inexpensive acrylate polymer which has a capacity to absorb 170 ml of water per g has been developed. It can be used to concentrate dilute solutions of macromolecules such as proteins, nucleic acids, and carbohydrates. The polymer absorbs only low-molecular-weight substances such as glucose, sucrose, and inorganic salts. It can replace the various conventional concentration methods. No special device or electricity is needed for the concentration. The inexpensive polymer, molded in the form of rods, can be very conveniently used as "disposable concentration sticks."
一种简单且价格低廉的丙烯酸酯聚合物已被研发出来，它每克能够吸收170毫升水。它可用于浓缩蛋白质、核酸和碳水化合物等大分子的稀溶液。该聚合物仅吸收葡萄糖、蔗糖和无机盐等低分子量物质。它能够取代各种传统的浓缩方法。浓缩过程无需特殊装置或电力。这种价格低廉的聚合物被制成棒状，可非常方便地用作“一次性浓缩棒”。
