Help finding blender

Karo_lina

Hi,
I want to buy a blender to make emulsions in the lab. My standard batch is from 1 to 10 L. I am considering this two blenders: Here is their  technical data:

1.
Power supply (Volt / Hz) 230/5060
Power (Kwatt / Hp) 0.25
A mm ø75
B mm 285
Speed rpm 2500 - max 15000
Weight (Kg) 2,3

The length of the arm: mixing and knife :270 mm

 2.

Power supply (Volt / Hz) 230
Power (Kwatt / Hp) 0.4
A mm ø100
B mm 350
Speed rpm 2000 - max 9000
Weight (Kg) 2,4

The length of the arm: mixing and knife : 400 mm

Which is better? Or should I find something else?

Of course the one with 0.4Hp is better. 

But the best thing is to purchase an emulsifier head. Not just a mixer. 

There was a post a few days ago about it.
