Cubis II Micro Balance

The Sartorius Cubis II micro balance range reads from 1 µg (0.001 mg) to 10 µg across capacities from 1.1 g up to 111 g. Standard micro modules (10.6S, 6.6S and the dual-range 3.6P) and high-capacity micro modules (36S, 36P, 66S, 66P and 116S) share one modular premium platform: you choose the display (MCA 7-inch colour touchscreen or MCE touchscreen), the draft shield and the software. Automatic internal adjustment (isoCAL) and built-in data integrity controls make it ready for demanding research, pharma and quality control weighing.

Overview

The Sartorius Cubis II Micro Balances are modular premium balances for work where microgram readability matters: weighing small samples and filters, preparing standards, gravimetric and particulate analysis and low-dose pharmaceutical testing. One platform covers a wide range of capacities, from 1.1 g to 111 g, with readability from 1 µg (0.001 mg) to 10 µg depending on the weighing module.

Standard micro modules (pan Ø 30 mm, filter pan Ø 50 mm)

10.6S: 10.1 g with 0.001 mg readability.
6.6S: 6.1 g with 0.001 mg readability.
3.6P (dual-range): 1.1 g / 2.1 g / 3.1 g with 0.001 mg / 0.002 mg / 0.005 mg readability.

High-capacity micro modules (pan Ø 50 mm)

36S: 32 g with 0.001 mg readability.
36P: 10.1 g with 0.001 mg, or 32 g with 0.01 mg.
66S: 61 g with 0.001 mg readability.
66P: 12 g with 0.001 mg, or 61 g with 0.01 mg.
116S: 111 g with 0.002 mg readability.

Choose your display and software

The MCA has a 7-inch colour touch display with an intuitive interface, basic weighing applications and optional licensable QApp packages. The MCE has a touchscreen for routine weighing with the factory-installed basic applications and no licensable packages.

Draft shields and accessories

Micro balances are offered with an automatic, motorized round glass draft shield (M) that learns your preferred way of working, or a manual stainless steel draft shield (F) made for weighing filters with diameters up to 50 mm. For the F draft shield, titanium filter weighing pans (52 mm and 75 mm) and a safe-lock tube holder for reaction tubes up to 2 mL are available as accessories. Which draft shield suits each module is confirmed when you order.

Built for stable, traceable results

Monolithic weighing system with typical stabilization of 2.5 to 5 seconds, depending on the module.
Automatic internal adjustment (isoCAL) and automated motorized levelling.
Conductive-coated glass draft shields against electrostatic effects.
Technical controls for 21 CFR Part 11 compliance, an integrated audit trail and user management on the balance.

Exact values differ from module to module, so the table on this page shows ranges for the whole line. Tell our team what you weigh and how much, and we will recommend the right module, display and draft shield and share the exact figures from the datasheet.

Key features

1 µg micro readability Eight weighing modules cover 1.1 g to 111 g, with readability from 1 µg (0.001 mg) up to 10 µg depending on the module.
Dual-range (P) modules The 3.6P, 36P and 66P modules give a finer readability at low load and a coarser one over the full capacity in a single balance.
Modular premium platform Choose the MCA 7-inch colour touchscreen with optional QApp software, or the MCE touchscreen for routine weighing, plus the draft shield that suits your samples.
Automatic internal adjustment (isoCAL) The balance adjusts itself after a temperature change of 1.5 K or after 12 hours, so results stay reliable without manual routines.
Data integrity built in Integrated audit trail, user management and technical controls for 21 CFR Part 11 compliance, directly on the balance.

Key advantages

One platform, many capacities Pick the module that fits your sample size today, from 1.1 g up to 111 g, on the same premium platform.
Fast, stable weighing Typical stabilization time is 2.5 to 5 seconds and typical measurement time is 6 to 10 seconds, depending on the module.
Protection from charged samples Conductive-coated glass draft shields reduce the effect of electrostatic charges on the result.
