Description

The PolyVISC is a fully automated, benchtop capillary viscometer with an 11 position sample handler for unattended processing and testing of of dilute solution viscosity of polymers in organic solvents and aqueous solutions. A special coating permits testing with highly aggressive solvents, including concentrated sulfuric acid. Both transparent and opaque samples can be measured with the accuracy required by ASTM D 2857 and many other application-specific methods.

The ultra-stable thermostatic air chamber provides temperature control from 20°C to 135°C within ±0.01 °C (with available options). Because both the sample carousel and the viscometer are completely contained in the thermostatic air chamber, only the first sample requires a delay for thermal equilibrium.Built-in thermoelectric cooling enables testing below 40°C without the need for an external chiller.

The semi-automated Solution Preparation System (SPS) uses gravimetric (weight-to-weight) rather than volumetric methodology to prepare polymer solutions for relative viscosity measurement.

Features & Benefits

Designed to meet specific polymer industry needs

  • Meets methods ASTM D789, D1243, D1601, D1795, D2857, D3591, D4243, D4603, D5336, ISO 1628-1, 1628-3, 1628-5 and ISO 5351
  • Standard unit is compatible with organic solvents and aqueous solutions. Upgrade to PVDF/PTFE components permits testing with highly aggressive solvents.
  • On-board software with specialized polymer calculations determines relative, inherent, reduced and intrinsic viscosity
  • Ultra-stable thermostatic air chamber with AIRBATH® technology provides excellent temperature control (±0.01 °C) from 20 °C to 100 °C (high temperature bath option provides range to 135 °C)
  • Kinematic viscosity range: 0.3 mm2/s (cSt) to 20,000 mm2/s (cSt) in 100-fold increments.  Special ranges available.

Fully automated bench-top testing

  • User-friendly software controls the instrument and facilitates tasks such as sampling, measurement and viscometer tube washing.
  • 11 position sample handler allows for unattended operation
  • Automated processing reduces operator to operator variability

Compact, robust design

  • Bench-top design conserves valuable lab space
  • Built-in thermoelectric cooling requires no external chiller

Simplified maintenance & test versatility

  • Accurately measures viscosity of opague and transparent samples. Standard infrared sensors available for transparent samples and some opague samples.
  • AIRBATH® chamber allows for rapid temperature and viscometer changes
  • Uses either a modified Atlantic compound viscometer tube (applicable for most samples) or a modified Ubbelohde tube (for volatile samples)
  • Volatile sample testing option provides protection from solvent evaporation to enhance test precision and reduce the presence of toxic or corrosive vapors in the AIRBATH® chamber
