Digital colorimeter Simple OD monitor, miniphoto518R


Ideal for simple culture check. Compact size, easy operation.

Main uses

 Microbial turbidity measurement
 Colorimetric sample absorbance measurement
 Other applications requiring absorbance / transmittance measurement


Compact and lightweight for convenient use and transportation

Compact design

It is easy to move because it is small and takes up little space.

High accuracy despite being compact

Stable and highly accurate data is provided by using two silicon photodiodes for the detector. The high brightness LED of the light source can be used semi-permanently.

Easy operation

Zero adjustment of the blank solution is completed simply by pressing the CAL button. When the sample solution is set, the absorbance and transmittance are displayed. Pressing the HOLD button will hold the value, making it ideal for measuring cultures whose value tends to decrease over time.

Measure directly in the test tube used for culture

Sample volume is about 4ml

Use a test tube of Φ16.5 ~ 18mm or L type test tube of Φ18mm, and the measurement can be performed with a liquid volume of about 4ml.

Main Application

Crushing yeast, mold, plant, animal tissue
Crushing bones, teeth and limb of small animals
Crushing coat of electric cable, resin and asbestos samples


Powerful crushing of frozen samples by metal crusher

Tissue samples from organ, fungus and plant are put into container with metal crusher, set inside holder and freeze by using liquid N2, and then undergo crushing using impact of shaking. This method can prevent degrade and denature of material of interest because crushing while freezing. It can also addressed to dangerous samples since it handles samples inside closed container.

Only tens of seconds are needed to crush, effective for small samples as well

It may vary depending on samples but crushing time is generally about tens of seconds. This product doesn’t have freezing function though crushing process may finish before sample thaws. Method of this machine is effective for small samples as well and there is little loss of sample.

Bead beater-type homogenizer Beads crusher µT-12


Both swinging and powerful multi-sample & large-capacity at a reasonable price. High cost performance bead crusher !!

Main uses

 crushed animal cells or tissues
 crushing plant cell or tissue
 disruption of the bacterial cell
 crushed solids, such as tablets


It crushes maultiple samples powerfully

The pendular swing method of max 3,200r/min crushes sample powerfully. Although the maximum speed is slower than µT-01, the swing amplitude is 1.5 times larger than conventional model giving the same power of crush. This mechanism raising the crush power with amplitude rather than speed is reducing the heating of samples by bead friction. If cool holder (TH-0203) or pre-chilled samples are used, it is possible to keep temperature below room temperature even after crushing. Please refer to below table for detail.

Pendular swing method

Easy operation and silent operation

Operation is very easy; select shaking speed and set timer (1-300sec).
Since memory function is equipped, shaking speed and timer with high-frequency is possible to memorize.
In addition, it is very quiet compared with equivalent bead crushers.

Commercial tubes and materials for crushing are usable

Commercial tubes with 1.5/2.0 or 5ml screw cap are used for crushing. Stainless (SUS), zirconia and glass beads are usable. Stainless beads with φ2/3/4/5mm are available.

Loadable 5 ml micro tube

It can load two 5ml screw cap tube for mass processing which cannot be available in 1.5/2.0 ml tubes. For example, minimum 1g can be crushed for animal organs. Although the maximum shaking speed is up to 2500 r/min, it can provide enough power of crush since the amplitude is optimal.
