Bath Fluid Testing
A simple fluid analysis through JULABO Crystal can reveal a lot about your JULABO temperature control equipment. The presence of certain minerals and elements in your fluid could indicate deteriorating parts or expired fluid. Before you face a potential maintenance or service issue, let us take a look into your fluid and see what it’s telling us.

Extended Warranty
JULABO Shield extends the outstanding coverage of your 2-year JULABO warranty up to 4 additional years. It’s available for any unit purchased new within the last six years and can be added even if your original warranty has already expired!

Installation Operator Training
Let us deliver a product expert along with your new JULABO equipment. We will install, fill, calibrate and test your new equipment for optimal performance and then provide in-depth training so you can become an expert yourself!

JULABO Subscription®
The JULABO Subscription® model allows you to pay for our highly advanced PRESTO® temperature control units in fixed monthly installments.

NRTL Certification
Need UL or CSA inspections or certifications for a JULABO unit that’s not already NRTL-marked? We’ve got you covered. JULABO can conduct the necessary safety testing and certification to keep you in compliance with OSHA’s standards. Add an NRTL certification to your product purchase, and we’ll complete it prior to shipping.
