Choosing a lab balance for precision weighing usually comes down to how fine a measurement you need and how much you want to spend. Add a used instrument with visible damage into the mix, and the decision becomes even more practical: are you buying a balance to use today, or a balance to repair?
Quick verdict
For most labs, the practical pick is clear. The Uimoso Analytical Lab Scale is listed at USD 254.14 and gives you a ready-to-run analytical balance for everyday weighing. The Mettler Toledo MS105 NewClassic MF is listed at USD 789.00, steps up to finer readability, but this particular unit is used and sold as-is / needs repair. Unless you specifically need that finer weighing increment and are ready to take on repair work, the Uimoso is the balance that will get you weighing sooner.

Where the Uimoso Analytical Lab Scale wins
- It carries the lower of the two listed prices, leaving more money for lab supplies.
- It is new, so you are not inheriting a repair backlog.
- A 200 g calibration weight is included for routine verification.
Where the Mettler Toledo MS105 wins
- The MS105 offers a finer reading increment, moving you into precision territory that standard analytical balances do not cover.
- The electronics and internal mechanics function, so the core weighing components may be sound even though the housing is damaged.
- For a lab with repair skills, this is a way to put a finer balance on the bench at a specific price point.
Product notes
Mettler Toledo MS105 NewClassic MF
This balance is worth considering when your weighing task demands more than standard analytical resolution. The 0.01 mg readability is its strongest feature, and the 120 g capacity tells you it is meant for smaller samples. The unit is used, sold as-is / needs repair, and has a cracked draft shield housing, so you are taking on a repair project rather than a turnkey instrument. The electronics and internal mechanics are said to function, which may matter if you can source or fabricate a replacement draft shield and recalibrate the balance. Around its listed price, you are paying for the finer precision and accepting physical repair risk. Choose it only when you specifically need that precision and are ready to handle the work.
Uimoso Analytical Lab Scale (EA224)
This is the more straightforward choice for a lab that wants a working analytical balance without a side project. The Uimoso EA224 comes as a new unit and includes a 200 g calibration weight. Its 0.0001 g electromagnetic sensor sits behind a protective glass draft shield, and the integrated leveling bubble makes setup easier. The 220 g capacity gives you more room than the MS105's limit, and you can switch between grams, ounces, carats, and milligrams with one touch. The trade-off is that it does not reach the finer readability of the Mettler Toledo, so it is not a semi-micro balance. For standard analytical weighing, the lower listed price and new condition make it a dependable daily tool.
Final choice by use case
- Choose the Uimoso Analytical Lab Scale if you want a ready-to-use analytical balance for everyday lab weighing and want to stay at the lower end of the price range.
- Choose the Mettler Toledo MS105 only if your work genuinely requires semi-micro readability and you have the ability to repair a balance that needs work.
- For most standard weighing tasks, the Uimoso is the balance that will get you weighing sooner and with less risk.
