Choosing between lab balances scales often comes down to what you weigh most. If you're working with tiny quantities that demand fine resolution, you need a scale that can detect very small changes. If you regularly place larger containers or heavier samples, you need a higher capacity. The A&D FX-300iN and Ohaus SPX2202 approach these needs differently, and each has its own trade-offs.
Quick Verdict
The A&D FX-300iN is the pick for analytical work with small samples, thanks to its fine readability and legal-for-trade status. The Ohaus SPX2202 is the better fit for higher-capacity weighing, with a more approachable price.
At a Glance
| Feature | A&D FX-300iN | Ohaus SPX2202 |
|---|---|---|
| Price | $330.00 | $206.15 |
| Capacity | 320 g | 2200 g |
| Readability | 0.001 g | 0.01 g |
| Condition | New - Open box | Used |
Where Each Product Wins
A&D FX-300iN shines when:
- You need very fine readability for detecting tiny differences in weight.
- Your application requires a legal-for-trade scale.
- You prefer a new, open-box unit over previously used lab equipment.
Ohaus SPX2202 shines when:
- You need a much larger 2200 g capacity for heavier or bulkier samples.
- You want to keep costs down, with the price difference between the two at $123.85.
- A tested working scale with a history of regular calibration fits your workflow.
Product Notes
A&D Electronic Precision Balance Scale Model FX300iN
This A&D FX300iN arrives as an open-box unit, so it's new but the original packaging and paper directions aren't included. You'll need to download the manual from A&D's website. A company asset tag is attached to the bottom of the scale. The balance itself is a legal-for-trade, high-resolution precision model with 0.001 g readability and a 320 g capacity, making it well suited for biological laboratory work. It also offers a fast 1-second stabilization time, so you can take readings without long waits. If you need ultra-fine resolution for small samples, this scale gives you that capability in a new-condition unit. The missing box and manual are the main drawbacks.
Ohaus SPX2202 Precision Balance 2200g x 0.01g Tested Working Lab Scale
This Ohaus balance is a used unit that previously served in a research laboratory, with regular annual calibration throughout its service life. It's been tested and remains in excellent working condition. The scale offers a 2200 g capacity and 0.01 g readability, which is a step down in resolution from the A&D but a significant boost in capacity-enough for larger samples and containers. The balance was retired from active lab use during the lab's final calibration cycle, so the most recent calibration date is from late 2024, but the certification is no longer current since the unit has been out of service. No known operational issues are cited. For medical laboratory weighing tasks that need more capacity, this is a solid choice, provided you're comfortable with used equipment.
Final Choice by Use Case
If your work revolves around tiny samples and you need high resolution, the A&D FX-300iN at $330.00 is the one to get. If you're weighing larger quantities or want more capacity for less money, the Ohaus SPX2202 at $206.15 is the practical choice.
