Viscometers Configured to Solve Your Testing Problem

Viscometers from Lamy Rheology Instruments are unlike any other. Each model can be configured to almost any specification with the right spindles, temperature control and software. 

The Lamy Viscometers and Rheometers do not use springs or torsion rods that require frequent recalibration. They incorporate an integrated calculator for processing viscosity test results. All Lamy instruments feature a 7” touchscreen and come with a stylus. This easy-to-use screen lets you see all measurement parameters at the same time.

All Lamy Viscometers and Rheometers can connect to a computer via USB port for data transfer. All except the B-One Plus also offer an RS232 port, as well as printer connection capability via USB Host Port or Compatible PCL/5. 

What makes these viscometers unique?

  • Operates effectively without a spring, so all measurement ranges (low, regular and high viscosity) can be tested with one instrument.
  • Provides instant readings because the instrument doesn't need to take extra time to stabilize. 
  • Easier spindle attachment with bayonet fittings. 

Basic

B-One Plus Viscometer

BOne Plus

 

The B-One Plus Viscometer offers a viscosity measurement range of 33 to 240,000,000 mPa·s depending on what spindles are used (LR version 1 - 22,000,000 mPa·s.). This basic instrument allows you to conduct one-step viscosity tests on your samples. 

Features of the B-One Plus:

  • Wide speed and torque range - one instrument for most levels of viscosity.
  • Set measuring times for thixotropic products.
  • Unlimited number of speeds between 0.3 and 250 rpm
  • A set of spindles is included. (Choice of L1-L4 set, R2-R7 set, or KU 1-10 spindle.)
  • This viscometer is also compatible with MS-BV, MS-VANE, MS-SV, and MS-ULV spindles. (Not included with purchase.)
  • Option to add temperature probe for monitoring product temperature during testing.

First Plus Viscometer

FirstPlus

For your ultra-sensitive measurements, the First Plus Viscometer features a torque range of 0.05 to 13 mNm (or 0.005 to 0.8 mNm for LR). The spring-less design makes the First Plus a robust instrument for measuring dynamic viscosities. 

The instrument can be controlled externally with the optional Rheotex software.

The First Plus has:

  • A digital readout of the viscosity test conditions and results.
  • The capability to send results to a printer or computer.
  • A PT 100 temperature sensor (which indicates temperatures between -50 °C to +300 °C) to monitor the temperature of the sample.

The First Plus can measure viscosity within the range of 8 to 240,000,000 mPa·s, depending on the spindle used. (LR range 1 - 22,000,000 mPa·s.)

First Pro Viscometer

FirstPro ViscometerA step between the First Plus Viscometer and the RM 100 Plus Viscometer, the new First Pro Viscometer offers an economical option that compares to the Brookfield DV2. 

The First Pro Viscometer can measure viscosity within the range of 8 to 240,000,000 mPa·s, depending on the spindle used. (LR range 1 - 22,000,000 mPa·s.)

Features of the First Pro Viscometer:

  • Same speed range and spindle compatibility as the First Plus Viscometer.
  • Program and save one-step tests like the RM 100 Plus Viscometer.
  • A PT 100 temperature sensor (which indicates temperatures between -50 °C to +300 °C) to monitor the temperature of the sample.
  • Optional Rheotex software allows for external control and programming multi-step tests.

Advanced

RM 100 Plus Viscometer

RM100Plus

With the RM 100 Plus Viscometer, you can program your measurement methods directly using the touch screen, and save your data for export and analysis. It has a viscosity range of 1 - 780,000,000 mPa·s (depending on the spindles used). 

The RM 100 Plus has an integrated temperature probe that may be used to monitor temperature with or without the temperature control system.  

Features of the RM 100 Plus:

  • May be used to satisfy many ASTM, DIN, BS, EN, IOCCC, and ISO standards (see RM 100 Plus page for more information).
  • UD display available with use of MS-R spindles.
  • Able to connect to and directly control temperature control systems
  • Save one-step testing parameters on the instrument for future use. Test results may also be saved on the instrument. 
  • Optional Rheotex software allows for external control and programming multi-step tests.

Rheometer

RM 200 Plus Rheometer

RM200Plus

The RM 200 Plus can generate and fit flow curves without using a computer. It also has ports to connect to a computer or printer. It has a torque range of 0.05-30 mNm. 

The RM 200 Plus is a special rotating rheometer useful for research and development, as well as in a quality control production environment. 

Special features include:

  • Free selection of speed from 0.3-1500 rpm. 
  • Able to connect to and directly control temperature control systems. 
  • Can fit flow curves for Plastic viscosity, flow limit, Thixotropy, Regression model according to Newton, Bingham, Casson, and Ostwald.
  • Can have computer control of the entire test process with optional Rheotex software.

DSR-500 Plus Rheometer

DSR500RheometerThe DSR 500 Plus Rheometer provides same rheological features of the RM 200 Plus, and also gives you the option to direct curves and control shear stress directly on the instrument.

  • Connect to and directly control temperature control systems. 
  • Fit flow curves for Plastic viscosity, flow limit, Thixotropy, Regression model according to Newton, Bingham, Casson, and Ostwald.

Gel Timer

GT 300 Plus Viscometer

GT300PlusThe GT-300 Plus Gel Timer Viscometer allows you to test the curing time (or gel time) of products such as epoxies, adhesives, sealants, paints, and polymers. 

It's easy to test materials that can turn rock solid as they cure, because every bit of the instrument that could come into direct contact with the sample is disposable - the spindle, the sample cup, and even the temperature probe!

  • Temperature control options include no temperature controlroom temp - 300°C, 15°C - 60°C, or 0°C - 150°C.
  • Temperature probe comes in 5m lengths that can be cut away and disposed of after each test. 
  • Includes Rheotex software, which allows you to see the graph results on your computer screen, control testing through your PC, and save data directly on the computer.

Cone-Plate

Cone-plate measurements are ideal for limited sample quantities, and products that are difficult to clean. All CP models offer a huge measuring range, programming and recording test parameters, an integrated temperature probe, and compatibility with Rheotex software. 

There are two spindle attachment options: bayonet fitting, or the even easier AC265 coupling. (Must purchase AC265 model of the instrument for compatibility with AC265 spindles, and regular model for compatibility with bayonet spindles.)
