Tokyo Garasu Kikai Centrifugal Concentrator Vivaspin Tuebo15 (Vivaspin Turbo 15) 355-23-39-78 30,000 MWCO, 48 pieces VS15T22 New, unused I purchased this but no longer need it, so I am selling it. Immediate purchase is OK, but I am also listing it elsewhere, so I may remove it depending on the timing. 【About Shipping】 * Shipping usually takes 2-3 days. If you are in a hurry, please consult with me in advance. Centrifugal Concentrator Significantly reduces filtration time with a membrane that produces high flow rates and a multi-channel device structure. Dead-stop structure prevents buffer depletion due to over-centrifugation. Polycarbonate container that withstands high-speed centrifugation further reduces filtration time. Graduations allow you to check the concentration state.
