Choosing a lab balance scale for your lab means deciding between used and new instruments, between price and readability, and between a working unit and a repair project. The four analytical balances here span $150 to $789, so the real question is which trade-off fits your work.
Quick Take
If you need the lowest possible entry price and can handle calibration, the used Mettler AE 100 is the budget pick. If you prefer not to buy used equipment, the Prime Scales PS-203 gives you a 200 g capacity. For a ready-to-use used balance with fine readability, the Citizen CX 220 is a strong choice. The Mettler Toledo MS105 offers very fine resolution but comes with physical draft shield damage and is sold as-is for repair.

Decision Matrix
- Budget-first buyer: Mettler AE 100, provided you can calibrate it.
- Avoids used gear: Prime Scales PS-203 for a new balance with 1 mg readability.
- Precision buyer: Citizen CX 220 for 0.1 mg readability and a tested working balance.
- Repair-tolerant buyer: Mettler Toledo MS105 if you can repair or replace the draft shield.
Product Notes
Mettler AE 100 Analytical Balance with Draft Shield
This used Mettler analytical balance is the most affordable way into this group at $150. Its glass draft shield suits Physical Laboratory weighing, and the unit is described as functional despite scuffs and blemishes. If you already own calibration weights and are comfortable verifying accuracy, this is a low-cost way to add a full analytical balance to your bench. The tradeoff is that it does not include calibration weights and would need calibration before you can trust its readings. That makes it a project, not a plug-and-play scale, and it is better for an experienced user than for someone who needs accurate results immediately.
Prime Scales PS-203 New 200g Analytical Balance Digital Laboratory Scale with Draft Shield
The Prime Scales PS-203 is the only new analytical balance in this comparison at $389.99. It offers 200 g capacity, 0.001 g readability, a glass draft shield, high-contrast LCD, stainless steel weighing pan, tare and zero functions, multiple weighing units, and adjustable leveling feet. That feature set makes it a straightforward choice for general lab weighing, research, education, pharmacy, and quality control. The limitation is precision: 1 mg readability is less fine than the Citizen or Mettler Toledo models, so it is not suited to very small sample masses. The new condition removes the wear and tear questions that come with the used balances here.
Citizen CX 220 Analytical Balance Precision Laboratory Scale
The Citizen CX 220 at $699.99 provides 220 g capacity and 0.1 mg readability, making it the highest-capacity precision balance in this group. It is a used Biological Laboratory balance that is tested and working: it powers on, zeros to 0.0000 g, and responds to weight. The display, controls, weighing pan, glass draft enclosure, and power adapter are included. That makes it the most ready-to-use option for someone who needs a fine-resolution analytical balance without repair work. The limitation is visible cosmetic wear, including light marks and discoloration from age, so it may not look pristine on a lab bench. You are paying a higher price for the extra decimal place and the tested working state.
Mettler Toledo MS105 NewClassic MF Semi-Micro Analytical Balance
The Mettler Toledo MS105 NewClassic MF is the most expensive balance here at $789.00 and the only semi-micro model, with 120 g capacity and 0.01 mg readability. That resolution is attractive for very fine measurements. However, the unit has physical damage to the draft shield housing and is sold as-is for parts or repair, even though the electronics and internal mechanics function. If you can repair or replace the draft shield, this is a way to bring semi-micro capability into your lab. The limitation is the unknown scope of repair and the risk that it may not be reliable for accurate weighing until the shield issue is resolved.
Final Recommendation by Use Case
For most labs that need a working analytical balance today, the Citizen CX 220 gives the most practical combination of tested condition and fine readability. If you prefer a new instrument, the Prime Scales PS-203 is the one to buy. The Mettler AE 100 is the cost-conscious pick for someone with calibration experience, while the Mettler Toledo MS105 is a repair candidate for someone chasing semi-micro precision.
