Lab Unlimited UK

The Carl Stuart Group was founded in 1984 by Stuart and Gillian Smith. From a small beginning our business has grown to encompass many services and products, covering different market sectors and geographical regions. The focus of our business, however, remains the same. We are a customer orientated company and strive to meet and exceed your expectations in everything we do.

As our portfolio grew we decided to present and promote our product and technical service offerings under distinct brands.  The Laboratory instrumentation, consumables and technical & integration services are promoted under Lab Unlimited.

The Lab Unlimited product portfolio offers laboratory/analytical products from more than four hundred leading manufacturers. A substantial part of this offering is published on this very site. We also produce a printed catalogue that can be requested by emailing us.

  1. Brookfield Ametek 500 cP Viscosity Standard at 25C 500 CPS - Viscosity Standard

    Brookfield Ametek 500 cP Viscosity Standard at 25C 500 CPS - Viscosity Standard
    General purpose silicone fluids are the most commonly used standard for verifying calibration of your Brookfield Ametek Viscometer/Rheometer. Silicone Standards are Newtonian fluids which are accurate to ±1% of viscosity value. Silicone fluids provide excellent temperature stability and are less temperature sensitive than oil viscosity standards. Brookfield Ametek Viscosity Standards are certified by methods traceable to the United States National Institute of Standards and Technology (NIST). The selection of one or two fluids will normally provide sufficient measurement points to verify calibration of your instrument. All fluids are supplied in ½ liter (1 pint) containers complete with a certificate of calibration. Main Benefits Accuracy: ±1% of viscosity value Excellent temperature stability Recommended for use with Brookfield Ametek and most other rotational viscometers Most economical Special viscosity values and temperature calibrations available upon request.
