Compact Dual-Station Laboratory Spin Coater for Pulp Molded Prototype Development
Product Overview
The Compact Dual-Station Laboratory Spin Coater is a space-efficient, user-friendly benchtop coating system designed specifically for research laboratories, university pulp molding programs, product development centers, and small-scale prototype shops. This compact system prioritizes rapid prototyping and iterative experimentation, enabling fast sample-to-sample optimization of new coating formulations for molded pulp food containers, protective packaging, electronics inserts, and compostable tableware prototypes.
The dual-station design, controlled through a single intuitive touchscreen, allows operators to load two samples and run them sequentially or simultaneously, significantly accelerating the R&D cycle compared to single-station machines. Each spin head can be programmed independently—supporting different substrates, coating types, or parameters within the same run—while the compact footprint occupies minimal laboratory bench space.

Frequently Asked Questions
What types of 3D-shaped pulp molded products can be coated on this system?
With custom fixtures, the system can accommodate a wide range of 3D shapes including bowls, plates, trays, cups, food containers, electronics packaging inserts, and specialty molded products. Typical size limit approximately 100 mm footprint with 50 mm height.
Can this system handle both thin-film coatings and thicker barrier coatings?
Yes. The broad speed range (300-8,000 RPM, extendable to 10,000 RPM) combined with programmable acceleration profiles allows processing of low-viscosity solutions for thin films as well as higher-viscosity dispersions for thicker barrier layers.
Is the system easy to clean between different coating types?
Yes. The removable collection bowls are interchangeable, and each chamber can be cleaned independently. Detailed cleaning protocols are provided for common coating chemistries to avoid cross-contamination.
Does the system require a dedicated compressed air supply?
No. The system operates on standard AC power only, with an integrated vacuum pump for substrate holding. No compressed air is required.
What safety features are included?
Each station has lid interlocks, emergency stop buttons, overcurrent protection, and vacuum loss safety interlocks. Exhaust ports connect to facility fume extraction. All electrical components are CE-certified.
Can this system be used for student training and multi-user lab environments?
Yes. The intuitive touchscreen interface, lockable recipe storage, and straightforward cleaning protocol make it ideal for multi-user academic and industrial lab environments.
