Products Cryovial Tube solutions from LTT (Zhejiang Liquan Biotechnology Co., Ltd.) are designed for reliable sample preservation at ultra‑low temperatures. As a B2B manufacturer with ISO13485/ISO9001 and CE compliance, we supply high volumes and support customization for IVD testing, research, healthcare, and pharmaceutical production. Production occurs in a 100,000‑class cleanroom to maintain consistent quality.
Choose external or internal thread vials, with self‑standing or round‑bottom bases. Options include color‑coded screw caps, silicone O‑rings for enhanced sealing, clear graduations, and writable panels. Sterile selections and cleanliness levels (RNase/DNase‑free, non‑pyrogenic) are available for sensitive assays. Typical volumes range from 0.5 mL to 5 mL.
| Type | Best Use | Notes |
|---|---|---|
| External thread | General cryogenic storage | Threads away from sample area; strong seal with O‑ring |
| Internal thread | High‑density storage | Compact cap profile; confirm torque with gloves |
| Self‑standing base | Benchtop handling | Stable filling and labeling without a rack |
| Round‑bottom base | Box/rack density | Use with holders for benchtop stability |
External thread cryovials help reduce contamination risk around the sample contact area. Internal thread designs save space and improve box density. Both support secure closure when paired with matched caps and proper torque.
Vials are molded from medical‑grade polypropylene for toughness at low temperatures and chemical resistance. They are used in vapor‑phase liquid nitrogen environments and ULT freezers; autoclave tolerance up to +121°C applies only where design allows. Sterile, RNase/DNase‑free, and non‑pyrogenic options support molecular and cell workflows. Traceability is enabled by graduations, writable areas, and optional barcodes.
These cryovials are suitable for cells, tissues, sera, plasma, PBMCs, and temperature‑sensitive reagents. Dimensions align with common cryo boxes, racks, and canes for streamlined storage. Follow safe handling practices when transferring between LN2 vapor phase, dry ice, and –80°C freezers.
Leave headspace to allow expansion during freezing.
Verify cap integrity after freeze‑down and before transport.
Thaw gradually and confirm labeling in inventory records.
| Factor | Guidance |
|---|---|
| Volume | Match sample size; typical options 0.5–5 mL with headspace. |
| Thread style | External for contamination control; internal for storage density. |
| Base style | Self‑standing for benchtop; round‑bottom for compact boxes. |
| Cleanliness | Select sterile, RNase/DNase‑free, and non‑pyrogenic as needed. |
| Identification | Use color caps, writable panels, and barcodes for tracking. |
We support private‑label cryovials, cap colors, printed scales, barcode/QR codes, and tailored packaging. In‑house mold design and plastic molding enable dimensional adjustments, with ISO13485 management and cleanroom production for consistent outcomes.
