Ceramic Bead Strains Storage Tube
CODE: HBPT001-2
Microorganism lab
often separates some significative bacteria, which need to be stored and
transported for a long time, but so far, the methods of strains store are from
simple to complex, the time to keep is from short to long. For above situation
and simplify the procedures of strains store and recovery, prolong storage
life, our company developed the new generation of ceramic bead strain store
tube.
Ceramic bead consists of freeze tube, ceramic beads and freeze preserving fluid, and is mainly used for strains storage,
recovery and transportation.
Compared with
traditional strains store method, it has following obvious advantages:
1.Easy
to operate: pick fresh pure culture of bacteria, access it into strains storage
tube;
2.Strains
preserving quickly: it contains natural porous ceremic beads and is
conductive to absorption and preserving of bacteria. Freeze preserving fluid make strains
avoid influence of solution and ice crystals. After mixing, suck the fluid out;
3.Small
packing: 1.8ml freeze tubes.
4.Strains
long preservation time: frozen tubes are made of special materials, and have
excellent sealing properties and low temperature resistance. Bacteria can be
stored for 6 months at 2-8 ℃, for 12 months at -20 ℃ and for 24 months at -80
℃.
Strains preservation procedure:
Scrape off the fresh pure culture into strains preservation tubes from the plate cultured for over 18h, preparation of 3-4 McFarland turbidity bacterial suspension.
1.Tighten the tube; emulsify bacteria by shaking upside down a few times.
2.Suck up all liquid in the tube with sterile pipette, properly place aspirate of the liquid.
3.Tighten the tube, quickly place at -20 ℃ or -70 ℃ in the refrigerator.
Strain
recovery procedure:
1. Under sterile conditions, take a small ceramic bead with sterilized needle or forceps.
2. The small ceramic beads are used directly to inoculate
on agar by streaking or a suitable liquid medium.
