The hidden costs that come with replacing your lab bath too late

Your current baths are old or you have improvised heating solutions (the stories we’ve heard!), and there are certainly frustrations. 
Those frustrations may feel small at first but can lead to significant consequences for everyone in the lab.



Lab directors feel the pressure of wasted resources.

  • Unplanned costs eat into your budget. Constant repairs or lost samples can force you to redirect funds from other critical initiatives.

  • Reputation on the line. If inaccurate results or delays impact research or compliance audits, it’s not just the lab’s reputation at risk. It’s yours.

  • Missed opportunities for innovation. Time spent patching old methods or dealing with errors could have gone toward activities that advance your lab’s status.



Lab managers face relentless operational headaches.  

  • Workflows grind to a halt. Rework and inconsistent results cause bottlenecks, throwing off schedules and forcing managers to scramble for fixes.

  • Team morale takes a hit. Technicians get frustrated with unreliable setups, leaving you to manage not just the workflow but also the team’s stress.

  • Budget priorities shift painfully. Repair costs or inefficiencies may force cuts in other areas, like training or new equipment purchases.



Lab technicians feel the strain firsthand.  

  • Long days solving the same problems. When manual heating setups fail, technicians often bear the brunt, spending extra time troubleshooting instead of focusing on meaningful work.

  • The stress of errors weighs heavy. Inconsistent temperatures mean failed experiments, wasted samples, and the constant worry of explaining errors to management.

  • Burnout creeps in. Extended shifts to re-run tests or fix problems leave technicians feeling undervalued and overworked.
