New Peristaltic Pumps D-300

May 2024

The 300 series peristaltic pumps are intelligent pumps that combine flow, timing and filling dosing functions.

They can be operated by buttons, or controlled by an external signal or foot switch. The high-definition LCD display shows pump speed, flow rate, operating parameters and other information on the same screen.

It is a multifunctional intelligent product with the advantages of simple operation, stable and reliable performance, long-term continuous operation, and the ability to save input working parameters.

It is suitable for bioengineering, chemistry, pharmaceutical, hospital, food, production and research unit laboratories.

It is an essential product for fluid testing and scientific research.

The variable flow is from 0,002 to 1240ml/min. according to selected pump.

The motor, brushless, rpm is 300 with resolution of 0,1 rpm.

Version with 2 channel MC head with 10 rollers, expandable up to 12 channels, 2 at a time.

New Peristaltic Pumps Multichannel D-25Vplus

Date:  December 2023

Headline: New heads for DINKO Multichannel Peristaltic Pumps

Multichannel Peristaltic Pumps can drive several peristaltic tubes at the same time, which means that all the tubes give the same flow rate.

DINKO Multichannel Peristaltic Pumps are presented in the range modality D-25Vplus that provides the pumps with flow regulation, reverse flow, purge action and quick priming, ramp functions and automatic cyclic dosage, as well as the inclusion of a digital reader, membrane panel for command, external signal input 0-10V, 4-20mA and connection for remote control.

Also are available in the D-300 and D-28 peristaltic top gamme.

One with 2 channels and another with 4 channels  boths with 10 rollers capable of regulating flow rates between 0,01ml/min and 70,0ml/min for each channel.

Using auxiliary MC heads with 2 and 4 channels, pumps with up 12 channles can be mounted next to each other.

Both offer a very uniform cadence.

New peristaltic pump head CFV-4r

Date: December 2023                                                       Low flow

The new easy loading pump head CFV-4r get very minimal flow of 0,002 ml/minute with a maximum of 400 ml / minute.

In addition to the features already known of the D-25Vplus Peristaltic Pumps like to regulation of flow, reverse flow, purge and load fast action, functions of ramp and automatic cyclic dosage as well as the inclusion of a digital reader, membrane board for the command and signal input 0-10V and 4-20mA for remote control, also adds the CFV-4r pump head of four rollers in the D-28 top gamme DINKO Peristaltic pumps.

The 4 rollers of the CFV-4r pump heOad bring to the peristaltic pumps a pumping cadence very uniform.

The extreme rapidity in changing tube makes this pump head essential option in cases necessitating frequent replacement tube for pumping different liquids, or the need to sterilize.

Digital Vacuum Pumps

Digital Vacuum Pumps

Date: July 2022

The DINKO range of membrane vacuum pumps, type D-95, has recently replaced the analog vacuum and pressure gauges with digital models that facilitate a much more comfortable and accurate reading.

This improvement completes the one started in 2021 with the pumps equipped with digital reading controllers that allow the vacuum to be automatically maintained between two selectable limits.

Trichinoscope Model TriquiVisor Automat XY- HD

Dear Sirs

The  DINKO TrichiVisor Automat XY- HD, a new instrument for a sequential, precise  and  quick  exam of  tissue animals specially conceived for the detection of trichinas has recently been improved.

To this end, a new optical system has been incorporated into the TriquiVisor, which provides an illumination on the display screen, which is totally uniform and free from undesirable reflections that could make the user's work difficult.

Although the recommendations of the Order M.P. 17 January 1996 and the Official Bulletin  of the European Community of December of 2005 only prescribe to go from 40 increases of the images to 90, for tests, the new optical system of the TriquiVisor offers a continuous regulation from 35 to a maximum of 160 increases.

In addition, it has been possible to further improve the high definition of image offered by the old optics

The enhanced TriquiVisor Automat XY-HD is available now

Standards McFarland


McFarland Turbidity Standards

Dear Sirs

The Colorimeter DINKO according to McFarland measure the growing turbidity in colonies of bacteria’s in development.

As calibration standards are used precipitates generated by mixing Barium Sulfate, Barium Chloride and Sulfuric Acid, under the conditions set by McFarland (Journal of American Medical Association) and CLSI (Clinical & Laboratory Standards Institute)

DINKO added to manufacturing program Polymeric Standards contrasted with conventional precipitated of Barium Sulfate which give similar bacterial counts and have better consistency and stability
