Vacuum stirrer

Introduction

Tianjin  Sai Terui Technology Development Co., Ltd. based on Nankai University  strong chemical disciplines and personnel, is committed to fine chemical  products, experimental equipment research and development. Is to special to the institutions of higher learning, research  institutes and production enterprises launched the company developed the  multi-functional STR series of multi-functional vacuum mixer.
       
Currently  the world has a more popular mixing device, but the price is very high,  the company's STR series of multi-functional vacuum mixer is superior  to the similar products, with a very clear price advantage. STR series of multi-functional vacuum mixer has the following characteristics:
    
1, with universal joints, large freedom of space, easy to install,  and in the work of rotation under a stable, less prone to accidents.
    
2, the master of the blender on the gas nozzle for ventilation and  access to gas use, can constitute a vacuum system and ventilation under  the conditions of the synthesis system to meet the difficult  experimental requirements.
    
3, stirrer equipped with different standards and supporting the  mouth of the mixing rod, stirring pieces, accessories can be any  interchangeable, can be directly connected to the 50ml-20000ml reactor.
    
4, stirrer standard mouth of the top of a large nut in its large  screw on the rotation, if the agitator and the reactor is not easy to  separate, just spin the big nut can stirrer and reactor separation.
    
5,  the mixer is equipped with a special lubricant sealant can ensure that  the system in the normal rotation of the agitator to obtain sufficient  vacuum.

The vacuum stirrer is configured as follows:



Catalogue Number

Standard mouth and materialReactor volume
STR-BM stainless steel type19#,24#,29#Stainless steel standard port, with the top of the nut; additional 24 # glass standard portThe three  stirrers are suitable for 50-2000ml reactors, suitable for  semi-micro-synthesis, constant synthesis and amplification experiments
STR-BG glass type19#,24#,29#Glass standard port; additional 24 # stainless steel standard port
STR-BF PTFE type19#,24#,29#Teflon standard port, with the top of the nut; additional 24 # glass or stainless steel standard port

STR series of  multi-functional vacuum mixer comprehensive superior performance  indicators, chemical, chemical, pharmaceutical synthesis and many fields  of scientific research personnel rare handy experimental equipment.



Instructions for use

one. Installation and use
1. First, adjust the rotation direction of the electric motor to the clockwise direction by adjusting the outside line. Connect the universal joint to the motor without leaving the power supply.
2.  Apply 1-2 drops of lubricating sealant to the bevel of the agitator  spindle and insert it into the rotary sleeve of the agitator so that the  inclined surfaces of the two are in close contact and rotate the  spindle to achieve the lubrication and sealing effect. The small spring and the metal ring in order to set in the rotating spindle, the cover tightened. The  stainless steel or polytetrafluoroethylene standard port with a large  nut is screwed to the rotary sleeve of the stirrer. A silicone rubber  gasket shall be placed between the two, so as to ensure the vacuum  degree. If the lower part of the mixer to access the standard glass port, you  should be in the silicone rubber gasket and the glass standard port  rotation between the nylon connector, and the nylon connector and glass  standard port also have silicone rubber gaskets.
3, the stirring rod joint or stirring rod sleeve connected to the rotating spindle on the mixer.
4,  the stirring plate placed in the lower end of the stirring rod,  according to the volume of the reaction bottle and the stirring plate in  the reaction bottle position, within a certain range of stirring rod in  the stirring rod sleeve into or pull out to determine the position , You can stir the top of the lower end of the mixing rod screw rod in the top of a stirring vortex.
5, for the volume of 50ml and 100ml of the reaction bottle, short and short mixing rod can be used, just screwed to install.
6,  the above process can be completed only 5 minutes, simply put the mouth  and the standard mouth of the mixer can be connected to the power  rotation mixing. If you use the Teflon standard mouth agitator, you do not have to  apply a vacuum grease between the mouth of the bottle and the standard  mouth of the stirrer, but apply a stainless steel standard port or a  glass standard mouth agitator for vacuuming.
two. maintain
1, pay attention to the standard mouth of the blender not to metal  parts or other hard objects with each other bumps, so as to avoid  mechanical damage.
2,  generally 24 hours a day in the use of the case, the top of the blender  can be the main part of the closure cap spin, the rotating spindle out,  with a cotton cloth or soft paper dip toluene to wipe the spindle and  sleeve ,  Then 1-2 drops of lubricating sealant evenly applied to the rotating  spindle on the cone surface, the slant below the thin rod, there is no  need to smear.
