• Silverson L5M vs L5M-A

    Posted by PharmaSpain on May 9, 2016 at 3:51 pm

    Hi, I am deciding what homogenizer to buy 🙂 

    I decided to buy a Silverson becasuse of his quality/good comments in the forum.
    As I will start with a laboratory model, I thought to buy the L5M model. Now the spanish distributor informed me that it arrived a new model (presented as USA stadard model): L5M-A wich cost is about 700€ more (taxes not inc) 
    The difference are: 750w insted of 250w, and usb connection to use a Datalogger program (350€ more to purchase the program)

    I do not plan to use it to manufacture very viscous forms. My budget is quite limited but I could afford it if it really worth it / is really going to help.

    My question is:

    Does this model worth the extra price?

    Is so important in a practical way the datalogger program? (i attach picture)

    Thanks for your advice!

    This is really about your future needs. The 1hp (750W) motor is 3 times as powerful as the 250W motor. You may not need that extra power now, but it’s possible you will in the future. Also, the more powerful motor will not only allow you to move more viscous material, it will also allow you to move larger volumes of material. And, all things being equal, a larger motor with more power working at a lower percentage of its capacity is usually much more reliable than a smaller motor with less power working at a high percentage of its capacity - that should translate into a greatly increased lifespan for the L5M-A.

    Finally, it looks like Silverson no longer makes the L5M model at all, so if you buy one, you’d be buying a discontinued model, which I wouldn’t recommend, even if it is cheaper.

    Thanks @Bobzchemist 🙂 
     I did not know that Silverson was thinking about discontinuing the 250W model ! What do you think about the datalogger program?

    From their website, it looks like they’ve already discontinued the 250W model.

    The data logger program would be quite valuable if you are going to scale up in an advanced facility that has engineers capable of interpreting the results and applying them to their larger-scale machinery. It would also be helpful if you were making pharmaceuticals of any kind, since regulators love documentation. Otherwise, I’d consider it a very expensive toy.

    Ok, I see now why I did not notice they where going to discontinue it… They did not update the Spanish website version. I will buy A model but not the datalogger (yet). Thanks!
