The qVisc 4320AX successfully adapts our patented
tube design to a fully autosampled instrument. Married to a large 200 plus capacity
autosampler with a very flexible sample configuration and an optional pre-heated sample
rack, and recently updated with a new layout using less
plumbing, less sample and faster throughput, the qVisc is the answer for large labs who need unattended viscosity measurements
for large numbers of samples. Using less then 4.5ml of sample the qVisc measures
viscosity at two temperatures (typically 40°C and 100°C), or the qVisc can be configured for
single temperature operation using less than 2.5ml of sample.

brochure as well as a comprehensive white
paper on the
unique benefits of our patented tube design.

Features
| Totally automated, unattended viscosity determination at one or two temperatures from one sample. |
| Two baths, two temperatures, and eight tubes delivers up to 47 samples per hour at two temperatures and up to 64 samples per hour at one temperature. The autosampler can hold over 200 samples. Heated sample racks available for even higher throughput, especially on samples over 350 cSt. |
| Covers the range for almost any lubricating fluid viscosity and temperature with no tube selection or splitting samples. Heated sample racks extend the range with the same tubes. |
| Only 13 cents per sample at two temperatures. That's only $128 per thousand samples. |
| Compact floor stand design requires no compressed gases, fume hoods, or special venting requirements. Solvent vapors do not escape. |
| Advanced solvent additives and fully automated glass cleaning, work together to keep the instrument soot and build up free. Roll out instrument platform and strategically placed doors and pop off panels allow easy access for maintenance. |
| Advanced Windows based software controls the instrument and has flexible reporting options including managed daily log files, transfer to LIMS over serial or TCP/IP network links, save and restore sample information files, visually select sample locations, VI computations, and much more. |
| Only 80ml of solvent is used for a two temperature measurement and 50ml for a single temperature. |
| Patented tube design verifies ASTM D445 method applies by measuring how Newtonian the samples are, and also rejects inaccurate measurements in ways no other instrument can (see our white paper for more information). High speed optical meniscus detection is immune to changes in fluid darkness. |
| Advanced computer software automatically runs QC checks, and constantly checks the system for proper operation. At the first sign that a tube is not functioning correctly, or may be returning inaccurate results, the tube is automatically taken offline while functioning tubes remain working. |
| Smart controllers shut down if unable to maintain steady temperature. Separate over temperature detectors remove power if bath fluid too low or any other over temperature event occurs. At no time is solvent placed under pressure, all cleaning is done by simply drawing up solvent under vacuum. In the unlikely event of a leak, the solvent runs back into its container. |
