Today, our SPEX product line manager received a sample request from the customer. Let's take a look at this amazing instrument with him.

When ~ when ~ this is the SPEX liquid nitrogen freeze grinder 6870D, from the side we can see that it has two pre-cooling chambers and two grinding chambers, while grinding this group of samples can pre-cool the next group of samples , greatly saving your time

This is our grinding tank. Each grinding tank has a magnetically driven ram. This is the only moving part of the whole instrument, which greatly reduces the loss of the instrument.

Pour liquid nitrogen, load the sample, start the experiment and do the experiment. Are the little penguins with great sticks sprouting?

Set the parameters such as pre-cooling time, cycle number and frequency on the color touch panel operation panel, press one button “RUN”, why should you go, or simply take a break~

In a short while our first batch of samples came out.

Professional can opener, easy to open cans, save time and effort

Here is the time to witness the miracle. We made a total of three samples, polymer, silicon carbide and vitamin E capsules. Looking at the comparison chart before and after grinding, is the effect very shocking?

In fact, our SPEX freeze grinder can handle more than this, such as: bones, electronic components, fragile sensitive such as RNA, DNA are not in the words, if you have such sample pre-processing problems, please call the following Pei company The office telephone consultation, we will serve your scientific research with professional instruments and technology!
