Exceptional Sensitivity for High Accuracy Measurements

The TXB621L Precision Scale from Shimadzu presents highly accurate weighing of small samples or particulate matter thanks to its 100 mg sensitivity. Sturdy and constructed for laboratories even for educational institutions, production houses, or industrial facilities, the Shimadzu TXB621L generates reliable and close measurement values, securing high performance weighing for routinary lab tasks, manufacturing procedures, as well as quality control processes. Need other top loading balance options with the same 100 mg readability? Go for the TXB2201L Precision Scale from Shimadzu. But if you want a model having a higher division size, check out the TXB222L Precision Scale from Shimadzu.

Paramount Reproducibility for Efficient Weighing

When it comes to achieving results that can be duplicated for weighing applications done on a daily basis, you can trust the TXB621L Precision Scale from Shimadzu that presents 100 mg repeatability. Even with multi users considered, the unit yields close measurement values all throughout your complete weighing process for valid results, taking into consideration that the similar conditions are carried out. If you need higher repeatability from the same MFG or another globally-recognized brand, you can opt for the TXB422L Precision Scale from Shimadzu instead

Versatile Weighing for Lab, Field, and More

Cover 620 g of a range of samples with this Shimadzu model constructed with a spacious 110 mm weighing pan. Whether working in the lab or field or examining solids, liquids, and other sample types, this scale verifies weighing accuracy and precision through its internal calibration feature. No need to worry in case you move the unit from an area to another because it can re-calibrate accordingly as required.Dealing with heavier samples? The TXB6201L Precision Scale from Shimadzu or the WLC 6.X2 Precision Balance from Radwag offers a higher capacity but with the same readability as the Shimadzu TXB621L.

Significant Features to Take Into Account

Internal Calibration icon Internal Calibration

This Shimadzu TXB precision scale comes with an internal calibration feat, adjusting as desired while considering changes in temperature, movement, time, and stability. This assures weighing accuracy and precision even if the unit is relocated on a daily basis.

Alphanumeric LCD icon Alpha Numeric LCD

With the Shimadzu TXB621L precision balance, operational efficiency becomes better as weighing results are vividly shown right away through its perfectly sized, robust, and bright Alphanumeric LCD screen. Even if users are in badly lit rooms, clear data readout is still warranted.

Clearcut Operational Excellence

The TXB621L Precision Scale from Shimadzu is key to amplifying laboratory weighing output. Operational efficacy is strengthened because this Shimadzu precision scale also has RS-232 and USB ports, enabling users to transfer data to various computers, devices, and even printers in a shorter period of time.

Menu Operation Key

Easy to operate key layout

Menu navigation keys are separated from weighing operation keys and arranged in a familiar 5-way navigation circle. Up, Down, Right, Left and Enter are the simple operational steps.


Easy Setting

Best fit to weighing application

Quickly adjust the desired ratio of stability and response for every application, even during measurement, with one touch operation.


WindowsDirect Communication Function Only a cable is needed to send weighing data to a computer

Send balance data to Excel or other Windows applications without any data communication software installation required. All you have to add is one RS-232C cable. By combining standard AutoPrint functions with typical spreadsheet functions, even difficult applications can be easily automated.


Can be used anywhere with battery power

Power the TXB series balances by AC adapter or batteries.


Expanded Piece Counting function

Unit weights of up to 5 different samples can be easily entered, stored and recalled for use.


Illuminated display provides comfortable display visibility in all settings.

A liquid crystal indicator with attractive light blue backlight is standard on all models. The TXB series has additional power saving features: the backlight automatically shuts off when idle and lights up again when weighing operations resume.


Comparator function

Compare samples to target values or pass/fail criteria and clearly indicate the results.


RS232C interface

All models include standard RS232C interface for easy integration with other devices and computers


Streamlined design for anti-theft options

Industry-standard Kensington Security Slot accommodates the widest variety of optional anti-theft security devices.


Change among many weighing units and functions with a single touch

In addition to grams (g), weigh in %, number of pieces, ct, kg, mg, lb, oz, TTI, etc. or a custom conversion more than 20 unit in all. Change quickly from display of % or counting to gram weight (g) display.


Durable, high performance aluminum alloy mass sensor UniBlocSince 1987

The TX/TXC series incorporates a one piece aluminum alloy mass sensor technology (UniBloc) first introduced by Shimadzu for precision balances in 1989. It excels in performance, resists deterioration and damage by ordinary impacts. The UniBloc’s compact, uniform structure replaces 70 parts found in a conventional electromagnetic balance sensor assembly and ensures stable temperature characteristics, excellent response time and stable corner-load performance. The UniBloc design permits a consistency of production that assures reliability and a long operational life.


Fine measurements are assured with sliding glass door windbreak system

TXC and TX models with 1mg minimum display feature a sliding glass door type windbreak as standard configuration. The highly transparent system includes semi-transparent corners and maximum door opening capability.


Fast and flexible calibration

Balance display provides prompts for calibration procedure and accepts your choice of external calibration weight.


Many useful functions included

  • Alpha-numeric menu display

  • Up-front level indicator on display panel

  • Door cleaning is simplified

  • Stainless steel pan

  • Choice of weighing modes

  • Zero tracking function and settings

  • Continuous data output function
