Single-layer and double-layer selection
Standard model designation: ORSSHA344-25, -45, -60, -150, -180 and -200 indicate the main model capacity class.
S model designation: ORSSHA344-25S, -45S, -60S, -150S, -180S and -200S are used for the corresponding S / double-layer configuration.
Platform number: the table includes both 1-platform and 2-platform configurations for the same capacity family.
2000 ml Erlenmeyer flask reference
Application-oriented reference: 2000 ml flask positions are added as practical capacity guidance.
Example: where the platform supports 15 × 1000 ml flasks, the comparable 2000 ml configuration may be approximately 7 × 2000 ml.
Final confirmation: flask geometry, clamps, platform configuration and available working height must be verified before final quotation.
Capacity values are prepared according to the supplied model table. The 2000 ml Erlenmeyer flask line is included as an application-oriented configuration reference and should be checked against final platform accessory configuration.

🖼️ Visuals, Platform Accessories and Support
Platform accessory note
Flask clamp configuration: final capacity depends on selected clamps, flask diameter and platform layout.
Working height: double-layer operation and large 2000 ml Erlenmeyer flasks require confirmation of available working height.
Quotation requirement: specify flask volume, number of flasks, single-layer or double-layer setup and expected shaking speed range.
