Temperature Control For Distinguished Lab Managers, Pt. III: Polycarbonate Vs. Stainless-Steel Tanks

In our last post, we discussed the differences between open bath circulators and closed, highly dynamic temperature control systems. As a lab manager, knowing those distinctions between open- and closed-loop systems – and which process flow works best for your applications – is critical.

But there’s another important distinction to be aware of: polycarbonate bath tanks vs. stainless-steel bath tanks. And this is what we’ll look at today.

When deciding between a polycarbonate & stainless-steel tank, ask yourself four questions.

  1. Do you need sample visibility? A polycarbonate tank allows you to view samples during incubation for temperatures up to 100°C. Browse Transparent Bath Tanks
  2. Do your applications require temperatures >100°C? If so, then you’ll need a stainless-steel tank. See What Stainless Steel Has To Offer
  3. Do you need to drain your bath tank frequently? If the bath fluid (particularly water) needs frequent changing, then you’ll do best with a stainless-steel tank. Polycarbonate tanks do not have a drain, and must be tipped or siphoned to remove bath fluid. JULABO Stainless-Steel Bath Tanks – (except for the B5 model) incorporate a drain port to facilitate fluid removal.
  4. Do you need depth variation for your internal samples? For internal applications with varying sample depths, it’s best to use a stainless-steel bath tank with an immersion-height adjustable platform. Check Out Immersion Adjustable Platforms

As a stellar lab manager knows, materials matter. So, whether your application demands perfect sample visibility or a higher temperature range, drain port and height-adjustable platform, make sure your bath tank meets all the requirements for smooth and safe operation.

Stay tuned for the last installment in our “distinguished lab managers” series for some elucidation on yet another crucial distinction: internal circulators vs. external circulators.
