NH-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are joined together at a secondary amine. Terminal alkynes are reactive towards azides in copper (I) click chemistry to form stable triazoles with the target compound. The secondary amine joining the two arms can be used as a nucleophile such as in alkylation via reductive amination or in forming amides with carboxylic acids or activated NHS esters. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

Key features： 1. High-definition LCD touch screen, simultaneously displaying operational parameters: speed, temperature, vacuum, and running time. 2. Delayed start: after reaching a fixed speed, Start the vacuum pump to effectively prevent sample mixing. 3. Fully automatic vacuum control system, vacuum setting range0.1~1000mbar, Control accuracy0.1mbar. 4. 1.5/2ml Rotor stacking for simultaneous use; rotor replacement without tools. 5. Programmable with temperature and pressure settings; capable of storing 36 programs 6. Compatible with various rotor heads; transparent glass window for easy observation. 7. Magnetic drive: maintenance-free, non-contact drive, fully sealed. 8. Safety in use: inductive electric self-suction door lock ensures the centrifugal concentrator can only start when the door cover is fully closed and locked. 9. Can be used in conjunction with freeze-drying systems Model: SD-25/SD-25C
