Semi-Micro Analytical Balance Simplifies High Resolution Weighing

The LF-225 DR semi-micro balance

The LF-225 DR multi-function dual-range semi-micro analytical balance offered by Tovatech is an ideal solution when highly accurate weighing is required on a regular basis.  This balance is crafted in Japan with exceptional quality workmanship. Researchers, jewelers and others can benefit from the readability of 0.01 mg up to a 92 g capacity or 0.1 mg up to a 220 g capacity.  Linearity in these ranges is ±0.03 and ±0.02 mg; repeatability is ±0.02 and ±0.1 mg respectively.

The USB port on this Windows® compatible balance simplifies transfer of data to a pc or printer.

Featuring a one-key calibration function the LF-225 DR semi-micro balance has internal weigh chamber dimensions of 6 x 6.25 x 9 inches, an unusually tall space. The novel sliding door mechanism permits users to open the right side glass door with the left hand while placing samples on the weighing pan with the right hand (or vice versa).  Doors slide into the scale’s cast aluminum and static-resistant ABS housing instead of protruding into the area behind the balance.

 A Semi-Micro Balance with Multiple Weighing Options

In addition to precision weighing the GLP-compliant LF-225 DR can be programmed to perform the following functions:

  • Statistics
  • Checkweighing
  • Accumulation
  • Counting
  • Percentage calculations
  • Density determination
  • Below balance weighing

Users select weighing units of gram, milligram, carat, ounce, pound, troy ounce, pennyweight, grain and momme.

Special Features Support Accurate Weighing

Users of analytical balances understand that a stable environment is essential to accuracy.  This entails minimum, ideally no exposure to vibration, temperature and humidity changes.   Two special features on the LF-225 dual range semi-micro balance enhance accuracy.

  1. Three levels of adjustable environmental filter settings adjust the balance response to differing environmental conditions  for more controlled results
  2. An anti-buoyancy plate ensures air currents within the weighing chamber do not affect weighing results

Record keeping connectivity options are a supported by a selectable baud rate to data collection devices, and a USB or RS 232 interface with supplied RTS data collection software for Windows.  Options include an SDI remote display, printers, ionizers, aluminum weigh pans and a density kit.

The semi-micro balance is shipped with a comprehensive user manual.

About Rachel Kohn

So how did an MIT Ph.D. end up selling refrigerators? When I figured out that a lot more scientists buy lab refrigerators than innovative leading-edge instruments. I hope that my many years of lab experience will help you find the right equipment for your work. Before co-founding Tovatech I worked in business development and project management at Smiths Detection, Photon-X, Cardinal Health, and Hoechst Celanese. And before that I spent 12 years as an R&D chemist at Hoechst Celanese and Aventis working on advanced drug delivery systems, polymer films and membranes, optical disks, and polysaccharides. Some day, eventually, I’ll make enough money to develop an innovative technology that will change the world. Read More
