Product Description:

Chlorophyll A grinder JXFSTPRP-YLS-01 (patented product, counterfeiting must be punished! 2013200394108)

skills requirement:

Equipment use: It should be suitable for the extraction and mixing of chlorophyll in tap water and plant samples. It must meet the relevant requirements of "Determination of Chlorophyll a in Water Quality Spectrophotometry" HJ897-2017. The sample can reach the micron level after 3 minutes of grinding.

It can be matched with most centrifuges on the market. After grinding, the sample does not need to be transferred again to prevent sample loss.

Dual platforms, multi-channels, large number of operations, good effects, adjustable speed, easy operation: built-in program controller, can set the grinding time, rotor vibration frequency and other parameters.

No cross-contamination: The sample tube is in a fully enclosed state during the crushing process, and disposable centrifuge tubes and beads can be used. The sample is kept in the tube completely to avoid cross-contamination between samples and external contamination.

The grinding time is digitally adjustable, 0-9999 minutes.

The program can be set and adjusted according to requirements, and the instrument has its own acceleration, running, and buffering three stages.

The instrument has an independent vibration unit and control unit to avoid resonance.

Professionally designed, the grinding chamber is transparent and visible.

220V 150W DC brushless electric drive.
