So you haven’t noticed our plastic totes for biopharmaceutical labs? There’s a good reason why.

June 16, 2017 By Melissa Leave a Comment

 

Example of a biocontainer

In Biopharmaceutical labs, researchers use biocontainers (large, see-thru plastic bags) to store liquids like process solutions and Active Pharmaceutical Ingredients (API’s). These bags can be any size and range from small, 20ml, all the way up to 2000 L. The larger the bags, the more need for rigid storage, like a rectangular or cylindrical plastic tote to fill and transport the liquids.

Plastic Concepts designs and manufactures the best totes (a.k.a rigid biocontainers) on the market, but I bet you didn’t notice…. and there’s a good reason why.

There is a popular quote in the design world:

“Good design is in all the things you notice. Great design is in all the things you don’t.”

poor design

For example, have you ever pushed on a door that was meant to be pulled? It’s because of the design of the door. It probably had a handle on the push side rather than a flat plate or push bar. Doors that work like they are supposed to, go completely unnoticed.

Just like our totes.

When you use our totes, you will think about other things entirely. 

Here’s why our tote design is utterly and completely unnoticeable:

  1. Strong material and stronger seams: Our totes are fabricated with heavy-duty, thick gauge Polypropylene*, which is practically indestructible. If you read our previous post on welds, you’ll know that our welds are designed to make the integrity of the structure stronger. So you won’t be wondering if your tote will be sturdy enough to hold and transport 500 liters of a solution without cracking or breaking at the seams.
  2. Access Panel: With the much larger totes, an access panel is required so that the user can reach in toward the bottom of the tote. Our access panels slide out easily and won’t crack like ones made from thinner plastic. Also, the locking mechanisms are made of heavy gauge plastic or metal so they slide easily. You can be sure that they will open when you want and close when you want without it snapping off. 
  3. Built-in casters and handle: Some other totes on the market require a separate metal cart. We can make totes with wheels and a push-handle built right in. So, you can save all the aggravation you’d have from trying to lift the tote onto a moving cart for when you’re stuck in the traffic on the way home from work.
  4. Designed for lifting with a forklift: The openings on the bottom are built into the design so you can rest assured that the tote will lift and not tip.
  5. Designed to fit ANY bag/biocontainer from ANY manufacturer: Often times, the totes you purchase will only fit the bags from the same manufacturer. We know that you like to have choices and we can design our totes to fit bags from multiple manufacturers. So, you can buy the bags that make the most sense for your budget and the ones that will get to your lab when you need it.
Our totes go unnoticed every day at these great laboratories:

Genzyme, Lonza, Biogen, Fuji, Bristol-Meyers Squibb, ASI, ThermoFisher, Novo, Regeneron, and Abramson Research Center, just to name a few.

(And, as an aside, if you’re anything like me and get jazzed about all things design you might be interested to read the Ten Principles for Good Design written by Dieter Rams, a well known industrial designer. (I would like to note that our totes have each of these 10 things *pats self on back*).

Or if you’re into podcasts, you’ll love 99% Invisible which talks about the unnoticed architecture and design that shape our world. Or read “The Design of Everyday Things” by Donald A. Norman.)

*Materials we use are USP Class VI and stainless steel

Ducted vs. Ductless Hoods – what’s the best choice?

May 24, 2017 By Melissa Leave a Comment

ChoicesIf you read our previous post about the preconceptions of ductless fume hoods, and why that’s changed, you will likely find yourself asking – “What is the right choice for my lab?”

Here are some things to ask yourself when choosing between ducted and ductless hoods… 

  1. What chemicals are you using?

    Before you purchase your ductless hood, be sure to collaborate with the vendor of the filters so they can ensure that the chemicals you’ll be using in the hood are suitable for filtration and that you’ll use the correct filter(s).

  2. How often will you have to replace the filters?

    Although ductless hoods save a lot of money on heating and cooling costs for your building, the price of replacement filters is something to consider. If your usage will require constant replacement of the filters, you’ll want to make sure this is in your budget. (Your filter vendor should be able to help you determine this). Our partner, Erlab creates filters that typically require replacement in 12 to 18 months.

  3. Are you renovating a lab in an existing building?

    If you are in need of a renovation but your building space won’t allow for HVAC alterations, then ductless hoods are the way to go. They can go anywhere in your lab where there is an electrical outlet.

  4. Are you trying to create a greener lab?

    If so, consider Erlab’s ductless hoods. Erlab’s hoods are installed in many LEED-certified labs in the U.S. and can “green-up” your lab because: the used filters are completely recyclable, filtering lab air means the energy used to heat and cool the building decreases tremendously, and lastly, if you’re filtering the chemicals rather than exhausting them into the atmosphere, you’re decreasing the amount of pollutants in the air.

In summary:

Ducted Fume Hoods

PROS

  • Can handle most chemical applications and larger volumes

CONS

  • Installation cost is very high
  • Timely to install, typical delays
  • Multiple trade coordination

Ductless Fume Hoods

PROS

  • Mobile
  • Quick and easy installation

CONS

  • Can only be  used with specific applications
  • Annual maintenance reviews are required

Plastic Concepts has many hood options as part of our catalog and we’d be happy to help you determine which is the best fit for your lab.

Plastic vs. Metal – Which is best for your project?

May 5, 2017 By Melissa Leave a Comment

Most of what we fabricate here at Plastic Concepts with Polypropylene and other plastics can also be fabricated with metal/stainless steel. Often times, plastic is a great replacement for metal, but sometimes, it really isn’t the best way to go.

So, which material is best for your project?

Our list of pros and cons below will give you a good general comparison of polypropylene vs stainless steel. There are variations within each material and each will have their own characteristics, so for this conversation – we’ll keep it general.

If, by the end of the article, you’re still unsure – give us a call and we’ll be happy to talk you through it.

Plastic

Pros:

  • Machinability – It is easy to cut through and its low melting point and high malleability make it conducive to fabricating more complex shapes.
  • Perfect for use in Environmental labs where metal can be an issue.
  • Does not ding or dent like stainless steel can.
  • Chemical resistance- Plastics are less likely to become damaged due to chemicals or chemical reactions whereas metals can oxidize or rust.
  • Since it is easier to machine than metal, it is easier to meet demanding timelines.
  • Custom applications are affordable and quick.
  • Field modifications are easy.
  • The life span of polypropylene is longer than metals in most applications.

Cons:

  • Polypropylene can degrade when exposed to extreme temperatures.
  • If there is no UV inhibitor in the plastic, it is not suitable for prolonged outdoor use as the UV exposure can cause polypropylene to become discolored or crack.

Stainless Steel

Pros:

  • More heat-resistant – metals tend to have a higher melting point than plastics.
  • Operating temperature – metal can be used in extreme hot and cold temperatures
  • Metal has a higher tensile strength than plastic.
  • Stainless steel is durable and easy to clean.

Cons:

  • More likely to require post-fabrication finishing like de-burring and painting which could add time and cost to the project.
  • More difficult to machine/fabricate.
  • Custom applications can be costly and have a long production time.

Contact us with your questions and we’ll always point you in the right direction (even if that means it’s toward metals). And if you’re local, please come by for a tour of our shop. We love talking plastics to new people!

Not All Welds Are Created Equal

April 12, 2017 By Melissa Leave a Comment

If you’re reading this post, you probably already know that Plastic Concepts can make just about anything out of plastic, but focuses on creating products for laboratories: tanks of any size or shape, cabinets, carts, rolling carts, totes, pass thru’s for cleanrooms, fume hoods, changing stations and lockers… you name it, we can probably do it. 

Fabricating with plastic is a lot like working with wood or metal — you measure, cut, mill, and put pieces together. One main difference here (other than the material) is the Plastic Weld. 

I’m sure you thought welding was just for metals, right? It is a similar process, although, while welding with metal requires an electrical arc to adhere the surfaces together, the plastic welding process uses hot air and gases to heat and seal the plastic together. 

So, the plastic weld, at first impression, seems simple. You have a gun that heats air or nitrogen, and the plastic welding material is fed through and adheres to whatever you’re working on. 

But it’s much more than that – not all plastic welds are created equally. It takes experience, patience, a steady hand and focus, to get it right. And getting is right is what sets Plastic Concepts apart!

Understanding the material you’re working with*, the correct temperature and air pressure, the manner in which you feed the welding material through the gun, the gas that you use and the rate at which you do it all can make or break the fabrication. It takes at least a year to get good at it.

Example of a chamfer if adhering the white piece to the black piece.

Some projects, like our large chemical storage tanks, for example, require stronger welds, and therefore a deeper chamfer. What’s a chamfer, you ask? The best way to describe it, is that it’s a 45-degree “gutter” that is cut along the edge of the plastic material. It’s cut onto the edge that will be affixed to the other piece, which is just a flat edge.

The larger the chamfer, the more welding material you use, and therefore the stronger the weld — each weld actually becomes stronger than the material itself. The chamfers that we cut for storage tanks (and certain other applications) are deep –  we take out 2/3’s of the material so that we have the space to fill it in with welding material. 

We lay down about 8-10 welding strips in each chamfer compared to the standard 2 or 3 strips and the more welds, the stronger the adhesion — and strong welds are everything! Especially in laboratories. Our tanks hold some awful chemicals and we are confident that when the tanks leave our shop they are ready for the job. 

More about finishing, standard welds, the tri-tip weld, temperature and gas in future blog posts.
