This aggregation reactor is equipped with a heating function, allowing it to be warmed to around 37°C to promote the aggregation reaction, making it easier to observe the aggregation reaction, which is difficult to see with the naked eye, through transmitted light. By mixing reagents with samples such as blood and eggs, the aggregation reaction can be clearly observed. The glass plate can be detached, making cleaning after measurements easy. Additionally, by preparing multiple glass plates, it is possible to prepare the next sample while measurements are being conducted.

The highly acclaimed check light has been newly upgraded to LED lighting. This device, designed with specially engineered light, makes it easy to observe sedimentation reactions in agar and various immune reactions such as antigen-antibody interactions that were difficult to see with the naked eye. With the transition to LED, it is now possible to adjust the light intensity, allowing for use as various confirmation lighting.

This is a microplate scratch tool for accurately conducting wound healing assays (scratch assays) using cultured cells. It scratches 96 wells at the same width simultaneously and precisely. The pin tips are made of stainless steel, allowing for repeated use under the same conditions. By performing all wells at the same time, it controls the width, length, and duration of the scratches consistently to create accurate comparative samples. Unlike resin or rubber materials like pipette tips, it can create wounds of the same width repeatedly without generating bubbles.

The cell disruption device "Organelle Collector" is designed to disrupt cultured cells and recover undamaged intracellular organelles (organelles). By rapidly suctioning and expelling within a tube without the use of chemicals, it disrupts cells through pressure, allowing for the extraction of each cellular organelle while maintaining their activity. After disruption, the desired organelles are fractionated using centrifugation. The cooling function reduces damage caused by heat during the disruption process.

Even when it is necessary to remove masks during meals or lectures, it prevents droplets from spreading to those around. In face-to-face meetings, there is space available for the exchange of documents and items. Additionally, colored (translucent) partitions are also available for workers, not just for meetings. This helps prevent accidents such as not recognizing the partition and accidentally bumping into or knocking it over.

DLC (Diamond-Like Carbon) is, as the name suggests, "carbon that resembles diamond," and it is very hard, has a smooth surface with a low friction coefficient, and can possess various characteristics. Tokken's ICF coating (which adds various functions to DLC) is highly excellent in antibacterial properties, anti-thrombus, low hemolysis, corrosion resistance, chemical resistance, and body fluid resistance. It is scientifically inert and stable, has no impact on living organisms, and is an environmentally friendly material. Tokken applies DLC coating to scientific instruments, experimental equipment, medical materials, and medical devices.

<Confirmation and Inspection of Agglutination Reactions by Microtiter Method> This device is an observation mirror designed to facilitate the observation of agglutination images visible at the bottom of microplates during the confirmation and inspection of agglutination reactions using microplates. It allows for stable observation of the reaction solution without tilting the plate, eliminating concerns about spilling reagents. By adjusting the angle of the mirror, it can be aligned with the observer's line of sight, making it suitable for long inspection periods and simultaneous observation by large groups (student practicals), as well as for photography.

The gel puncher is a cutting tool used to create gels for sedimentation reactions in agar gel. It eliminates the hassle of gel preparation. Since it can accurately create holes of the same size at equal intervals, precise reactions can be observed.

The check light is a device that allows for easy observation of sedimentation reactions in agar that are difficult to see with the naked eye. Unlike devices that shine light from below, which can cause glare and make it hard to see samples or reactions that are the same color as the light, this device clearly displays them. It can vividly show samples that are not visible in sedimentation reactions within agar gels, allowing for the observation of bacterial cultures and the unevenness of the gel surface. Since it does not shine light directly from below, it makes previously unseen or hard-to-see scratches and imperfections clearly visible. Thanks to its special indirect lighting structure, it can vividly display samples with low contrast. Additionally, unlike transmitted lighting, it provides a light source that is close to dark field illumination, making it very gentle on the eyes and preventing eye fatigue. It evenly illuminates the entire observation surface, allowing for uniform observation without any inconsistencies.

This is a device used to cool cells and other materials by immersing them in liquid nitrogen to keep the sample press section at ultra-low temperatures for coarse grinding.

• Crusher

The "TK-AM5" is a freeze-crushing device that immerses tissue samples such as organs, microbial bodies, and plants in liquid nitrogen to freeze them and then crushes them with impact. This device allows for the handling of samples at extremely low temperatures, enabling crushing while suppressing the decomposition or denaturation of target substances due to heat or chemical reactions. Additionally, by keeping the samples in a sealed state, it prevents contamination by other substances and sample loss. 【Features】 ■ Prevents contamination by other substances and sample loss ■ Enables crushing while suppressing denaturation ■ Ideal for the pre-treatment of protein, DNA, and RNA extraction, as well as for crushing agents and resins *For more details, please refer to the catalog or feel free to contact us.
