N-(t-butyl ester-PEG4)-N-bis(PEG4-Propargyl) is a trifunctional PEG linker that combines a t-butyl ester with two terminal alkynes. The alkynes can be applied in copper-click chemistry with azides to form stable triazole linkages with a target molecule, while the t-butyl ester can be deprotected and reacted with amines or alcohols to form amides or esters.

Freezer Dryer, 3kgs-6kgs water capturer
Model:
ST7003,ST7006,ST9006
Brand:
Yingtai
Character
Yingtai pilot-type freeze dryer completely simulates the technical requirements of the industrial freeze dryer,with a compact and reasonable design,a large redundancy range,and conforms to GMP and FDA standards.The ice condensation capacity is 4~18kg,and the WRL controller and liquid temperature control shelf are adopted,so that the process of pre-freezing and freeze-drying can be precisely controlled on the main machine,and the process results are quite comparable with the production machine.In addition to supporting the eutectic point test system,pressure rise and pressure comparison method to determine the freeze-drying end point and freeze-drying curve recording software,hallan pilot-type freeze dryer can also be equipped with engineering WRL control software to directly Graphical computer control the freeze-drying process.It can be configured with H202 sterilization and high-pressure steam sterilization orintegrated glove box system, which can be used for clean room operation through the wall.The cold trap and freeze-drying chamber are all designed with 316L stainless steel to ensure the cleanliness of the chamber and good ultimate vacuum and vacuum leakage rate to the greatest extent.
