When you're shopping for spectroscopy analysis detection equipment, you sometimes face two very different options at very different prices. The Roche 07341920190 Cobas Liat Analyzer is listed as new and sealed for $239.40. The GE Sievers TOC 900 LAB Portable TOC Analyzer is priced at $999.99. The real decision isn't just about price-it's about whether you need a ready-to-run analyzer for molecular testing or a total organic carbon analyzer that may need repair.
Quick verdict: If your lab needs rapid molecular testing for biological or microbiological applications, the Roche Cobas Liat is the clear choice: it's new, unused, and priced far lower than the GE. If you specifically need a TOC analyzer and are prepared to tackle repairs, the GE Sievers TOC 900 matches that application, but it comes with serious risk because it's sold as-is.
| Product | Listed Price | Condition | What It Does | Price Bar |
|---|---|---|---|---|
| Roche 07341920190 Cobas Liat Analyzer | $239.40 | New sealed | Molecular diagnostics for biological and microbiological labs | |
| GE Sievers TOC 900 LAB Portable TOC Analyzer | $999.99 | For parts or not working | Portable total organic carbon (TOC) analysis |
Where each product wins:
- The Roche Cobas Liat wins if you want a low-risk, ready-to-use analyzer and don't want to worry about previous lab wear.
- The GE Sievers TOC 900 wins if your work is specifically about total organic carbon analysis and you're comfortable restoring a unit.
Roche 07341920190 Cobas Liat Analyzer
The Roche Cobas Liat Analyzer is an unused analyzer from Switzerland, designed for biological and microbiological laboratories. It performs rapid molecular testing and includes integrated software to help streamline diagnostic workflows. The power supply is included, and the seller provides a 30-day guarantee on the entire inventory. The main limitation is that this is not a general-purpose spectroscopy or TOC instrument; it's built specifically for molecular testing. Also, while the analyzer is unused, the outer packaging shows some shelf wear, including tape on the top flaps and minor corner creasing. If your lab's testing needs align with molecular diagnostics, this is a low-risk choice. If you need TOC analysis, you'd need a different instrument.
GE Sievers TOC 900 LAB Portable TOC Analyzer
The GE Sievers TOC 900 is a portable total organic carbon analyzer made in the United States. It comes with a power cable and is described as having been tested to power on, which is useful if you're evaluating whether the unit can be brought back to service. That said, it's listed as "for parts or not working" and sold as-is, so you should expect to troubleshoot it. It's also priced well above the Roche analyzer, even though it's not in working condition. This only makes sense if your lab specifically needs TOC analysis and you have the ability to repair or refurbish this kind of equipment. Because it's sold for parts, there's no guarantee it will perform to spec after repair. If you're looking for a turnkey analyzer, this is not the one.
Final choice by use case:
Choose the Roche Cobas Liat Analyzer if you need a new, unused molecular testing analyzer and want to minimize risk. Choose the GE Sievers TOC 900 only if you have a specific TOC application and are ready to take on a repair project. For most buyers in the spectroscopy analysis detection space, the Roche is the sensible first pick.
