1, use: freezing tubes are mainly used for freezing and cryopreservation of samples, which can be used to preserve biological samples, such as cells, DNA, RNA, etc., under low temperature conditions. Freezing tubes have good sealing and freeze-resistant performance, suitable for long-term preservation.EP tubes (full name is Eppendorf tubes) are a kind of multifunctional test tubes, widely used for preparing reagents, mixing solutions, centrifugation and other kinds of experimental operations.
2, structure and capacity: the freezing tube is made of polypropylene or polyethylene material, with a round or conical bottom, and the capacity is between 0.5mL and 2mL. The bottom of the freezing tube is usually thicker, which helps the freezing and freezing of samples.EP tubes are made of polypropylene material with round bottom and the capacity is between 0.5mL and 2mL.
3. Labeling and identification: Cryostat tubes have a graduated line and labeling area, which makes it easy to mark information about the sample, such as sample number, date, and so on. The cryotubes are labeled using labels or stickers.EP tubes have a graduated line and a transparent casing, which makes it easy to observe the volume and status of the samples without additional labeling.
