Tell us about the common categories of centrifuge tubes

The tubes used for sample collection are generally lyophilized tubes or centrifuge tubes, blood collection tubes are used, plasma samples are collected with anticoagulant, serum samples are not required. Detection of an indicator of the sample should be collected at least 50 microliters, samples collected for short-term storage is placed in -20 ℃ storage conditions (about a month, long-term storage at -80 ℃ storage, remember that the sample is prohibited to repeatedly freeze and thaw.

The common types of laboratory centrifuge centrifuge tubes are as follows.

1, according to the material can be divided: plastic centrifuge tube, glass centrifuge tube and stainless steel centrifuge tube.

2, according to the speed can be divided into: low-speed centrifuge tube and high-speed centrifuge tube.

3, according to the capacity can be divided into: micro centrifuge tubes, small-capacity centrifuge tubes and large-capacity centrifuge tubes. Generally called the capacity of more than 100mL centrifuge tube for the centrifuge bottle.

4, according to the shape of the mouth of the centrifuge tube can be divided into: indented centrifuge tube and straight centrifuge tube.

5, according to the shape of the bottom of the centrifuge tube can be divided into: round bottom centrifuge tubes, conical bottom centrifuge tubes and flat bottom centrifuge tubes.

6, according to the centrifuge tube and the cap joint form can be divided into: press the cap centrifuge tube and screw mouth centrifuge tube.

7, according to the use can be divided into: preparatory centrifuge tubes and analytical centrifuge tubes.
