How It Works

How Benchtop Metering & Mixing Works

The MB-50-X meters two silicone components from a 20 oz Semco cartridge at a fixed 1:1 ratio, then mixes and dispenses them through a static mixer by the stroke rather than continuous flow — well matched to the shorter runs typical of formulation work. As a compact biologics dispenser, it's sized to sit on a standard bench without dedicated infrastructure, drawing only compressed air to operate.

MonoBiologics manufactures the MB-50-X in-house as part of a complete LSR metering, mixing and molding platform. Because it uses the same fixed 1:1 ratio as the Production LSR Metering & Mixing System, formulations developed here transfer directly to production scale without re-validation, and pair with the 8-Ton LSR Molding Press to complete the molding cell.

Why Benchtop

Precise 1:1 mixing at bench scale

The entry point into our LSR machine platform, sized for development, not production.

⚖

Bench-to-production consistency

Same fixed 1:1 ratio principle as the MB-600-X production system.

📏

Compact footprint

12 in. x 30 in., ~50 lbs, fits on a standard bench.

⚡

Fast changeover

Cartridge-fed with minimal setup between formulations.

🎯

Precise ratio control

No dosing drift across cycles.

🏥

Industrial & medical grades

Match specification to application from day one.

💰

Low investment

The most economical way onto the platform.

Where the benchtop system is used

Formulation development & screening

Bench-scale trials before committing to production volumes.

Low-volume production runs

Cost-effective dispensing for small batch sizes.

Medical device R&D

Medical-grade dispensing for early-stage device development.

Process scale-up validation

Prove the process before moving to the production system.

Academic & contract labs

Compact footprint for shared lab environments.

Bioprocess component prototyping

Early-stage components for single-use assemblies.

Scaling beyond the bench?

The Production LSR Metering & Mixing System handles up to 600 cc/min at the same fixed 1:1 ratio. Pair either system with the 8-Ton LSR Molding Press for a complete cure cycle.

FAQ

Benchtop LSR System FAQ

What viscosity range can the benchtop system handle?

50,000 to 2,000,000 cps.

What is the mixing ratio?

Fixed 1:1, two-component.

How is the system fed?

A 20 oz Semco cartridge.

What is the output pressure range?

0 – 3,000 psi.

What are the weight and footprint?

~50 lbs, on a 12 in. x 30 in. footprint.

Is it available in medical grade?

Yes, industrial and medical grades are both available.

Can formulations scale to production?

Yes, the production system uses the same fixed 1:1 ratio principle.

Does it require compressed air?

Yes, the system is fully pneumatic.

What's the difference versus the production system?

Output volume and feed method: the benchtop system is cartridge-fed up to 50 cc/stroke, the production system is pail-fed up to 600 cc/min.

Do I need a separate molding press?

Yes, pair the meter/mix system with the 8-Ton LSR Molding Press for molding and curing.
