Choosing a lab balance usually comes down to a trade-off: how fine a reading you need versus how much material you need to weigh. The Citizen CX 220 and Ohaus SPX2202 illustrate that trade-off clearly. One is built for analytical-level precision on small samples; the other is built for larger workloads at a more modest price.
Quick Verdict
If you're weighing small samples that demand high resolution, the Citizen CX 220 is the better match. If you need a balance for routine, higher-volume work and want to keep costs down, the Ohaus SPX2202 is the sensible pick.

Where Each Product Wins
Citizen CX 220: The better fit for micro-sample analysis where every decimal place matters. Its analytical design supports careful, precise weighing.
Ohaus SPX2202: The better fit for labs that routinely handle larger loads and want to keep equipment costs in check.
Product Notes
Citizen CX 220 Analytical Balance
The Citizen CX 220 delivers the fine resolution many analytical workflows demand, reading to 0.1 mg. Its glass draft enclosure helps protect small samples from air currents, and the included power adapter makes it ready to set up. The unit powers on, zeros to 0.0000 g, and responds to weight, as verified. Choose it when your samples are small and you need four-decimal-place accuracy. The trade-off is capacity: at 220 g maximum, it won't handle bulkier loads. The used unit shows normal cosmetic wear from previous lab use, and at $699.99 it is the more expensive of the two.
Ohaus SPX2202 Precision Balance
The Ohaus SPX2202 is the capacity specialist here, weighing up to 2200 g while still reading to 0.01 g. It comes from a research lab that kept it on an annual calibration schedule, and it has been tested and works as expected. The LCD display and fast stabilization make it convenient for routine weighing in a medical laboratory. The limitation is its coarser readability: if you need 0.1 mg resolution, this balance isn't the one. Priced at $206.15, it also offers a more approachable entry point for labs that don't need analytical-level precision. Remember that the calibration certification is no longer current, so you may need to recalibrate before critical work.
Final Choice by Use Case
Pick the Citizen CX 220 for small-sample precision. Pick the Ohaus SPX2202 for heavier workloads or tighter budgets.
