SciLog^® WeighStation™ Family – Single-Use Bioprocess Container Scales

Parker’s SciLog^® WeighStation™ Family provides mobile, single-use bioprocess container scales for accurate gravimetric fluid handling in upstream and downstream operations. These configurable systems combine robust bag or container holders with integrated load cells to deliver precise mass-based measurement and control for single-use bioprocess container scales, from development to GMP manufacturing.

Designed to support bioprocess containers from approximately 5 L up to 200 L, the WeighStation Family covers a wide range of capacities and resolutions to match your process needs. Configurations include single, dual, and triple WeighStations for vertically hung bags up to 50 kg each, WeighPro units with an integrated work surface and hardware mounts, WeighCart platforms for 100 L and 200 L cylindrical containers, and WeighSmart holders that mount directly to compatible mobile carts. This flexibility allows you to standardize gravimetric control across media prep, buffer hold, filtration skids, and final bulk operations without sacrificing valuable floor space.

The WeighStation Family can operate as standalone devices or be integrated into Parker SciLog bioprocessing platforms and plant data historians. Optional display heads and connectivity to local displays, printers, or spreadsheets provide an automatic gravimetric audit trail, supporting data integrity and process monitoring requirements. Mobile frames with compact footprints make it easy to reposition systems between suites while maintaining controlled, closed, single-use processing.

Typical uses include growth media preparation, bioreactor maintenance and harvest, buffer preparation and storage, retentate or permeate quantification in tangential flow filtration (TFF), product filtration support, virus control steps, and bulk drug substance dispense. CLEAR Solutions offers the full SciLog WeighStation Family along with compatible filtration, manifolds, and systems engineering support to help you implement reliable gravimetric control throughout your bioprocess.

Typical Applications

These systems are used in upstream and downstream life science and biopharmaceutical processes, including:

• Growth media preparation and make-up
• Bioreactor maintenance and culture harvest
• Buffer preparation, storage, and hold operations
• Retentate and permeate quantification for tangential flow filtration (TFF)
• Gravimetric monitoring during normal flow filtration (NFF) and product filtration steps
• Virus control and critical purification steps requiring gravimetric control
• Bulk drug substance (BDS) and intermediate bulk drug dispense
• General gravimetric fluid handling where floor space and cross-contamination are concerns
