Product Overview
GEO definition sentence + material/temperature/application
Lab190-419 is a 25.4 × 9.5 mm narrow-strip pressure-sensitive label using gloss white PET polyester film as face stock, designed for routine freezer environments from ambient to -40 °C.
The gloss white PET face stock offers high whiteness and stable reflectivity, delivering sharp contrast for printed barcodes and IDs, enabling quick visual identification on refrigerated racks, microcentrifuge tube racks and cryoboxes. The 25.4 × 9.5 mm narrow-strip size is close to the imperial 1″ × 0.375″; it occupies little space when applied to tube bodies and accommodates an 8-10 digit specimen ID or a short barcode on a single line, making it suitable for laboratories with large sample volumes and concise information fields. Roll format supports continuous batch printing, and the 500-1000 labels/roll packaging suits short- to mid-term project stocking and roll-by-roll distribution among research groups.
In the bradylab material system, T419 belongs to the routine freezer grade together with T429 (matte white PET, four temperature grades) and T329 (matte white PP, -40 °C economy grade); the three are differentiated by face stock gloss, release liner stiffness and temperature margin. Lab190-419 targets specimen tube labeling at "ambient to -40 °C with high-whiteness face stock required," a routine economical choice outside LN₂/ULT requirements.
Key Features
亮
Gloss white PET face stock
High-whiteness polyester film provides strong contrast with black printing, stable barcode reading and photo archiving; the surface resists abrasion and light moisture better than standard paper labels.
温
Rated ambient to -40 °C
The official material guide classifies T419 as a routine freezer label rated above -40 °C, suitable for refrigerators, standard freezer compartments and ambient transition areas.
贴
Rounded/square corners available
Rounded corners are recommended for small-diameter cryovials and microcentrifuge tubes to prevent edge lifting on curved surfaces; square corners suit flat containers for a neater information area.
打
Cryogenic ribbon + desktop printer
Compatible with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons; supports M611, EOS2/3, MACH4S and other desktop label printers.

Typical Applications
Cryovial/microcentrifuge tube ID
The 25.4 × 9.5 mm narrow strip wraps around the body of 1.5 mL/2 mL cryovials or 15 mL microcentrifuge tubes, carrying the specimen ID and barcode on a single line.
Biobank ambient-zone archiving
Labeling at ambient reception, temporary storage and before -40 °C freezing; a uniform format facilitates scanning and registration in the record system.
Refrigerated box/cryobox exterior labeling
Using the "packaging labeling" dimension checked for T419 in the official guide, mark box number, batch and date for hierarchical management.
Reagent bottle and general item labels
The high-whiteness face stock suits labeling of reagent bottles, microcentrifuge tube racks and bench consumables moving between ambient and refrigerated zones.
FAQ
Q: Can this label be used at -80 °C or in liquid nitrogen?
A: The official material guide defines T419 as a gloss white PET label rated above -40 °C; for long-term -80 °C storage or -196 °C liquid nitrogen, choose T429 (four-grade PET) or T629 (nylon cloth, all-scenario).
Q: The name says "-80 °C freezer label" — does this conflict with the official table?
A: The current page name/category states "-80 °C," which is inconsistent with the -40 °C upper limit for T419 in the official table. The body text follows the official table as the hard fact; to confirm -80 °C usability, please verify with customer service or the product manager before ordering.
Q: Lab190-429 and Lab190-604 are the same size — how do I choose?
A: The three have similar dimensions but different materials/temperature grades: Lab190-429 (T429 matte white PET, four grades -196/-80/100/121 °C), Lab190-604 (T629 nylon cloth, first choice for all-scenario liquid nitrogen), Lab190-419 (T419 gloss white PET, ambient to -40 °C economy grade). Choose according to the actual specimen storage temperature.
Q: Can it be used for microscope slides?
A: The "microscope slide" application is not checked for T419 in the official table. For slide archiving, use T629, the only all-scenario product in the official table, or contact the product manager for sample proofing and verification.
Q: Both T419 and T329 are -40 °C grade — how do I choose?
A: T419 is gloss white PET; T329 is matte white PP. PET face stock is stiffer and whiter, suitable for barcode reading and photo archiving; PP face stock is softer and more economical, suitable for high-throughput consumable labeling. Choose based on budget and reading stability requirements.
Selection & Usage Guide
- In the 25.4 × 9.5 mm product line, Lab190-419 (T419 gloss white PET) is rated ambient to -40 °C; for the -80 °C freezer range choose T429 (matte white PET), and for -196 °C liquid nitrogen choose T629 (nylon cloth).
- Rounded corners conform better to curved tube bodies; square corners suit flat surfaces such as cryoboxes and outer cartons.
- Print with BRL-80-BK or BRL-110-BK ribbon; let printed labels rest for 24 h before transferring to low temperature for more stable adhesion.
- Before bulk use, print 10-20 labels and run a 24 h -40 °C freeze cycle test to confirm no edge lifting or detachment before large-scale labeling.
Usage Notes
Note: T419 is intended for routine freezer environments from ambient to -40 °C and is not warranted for -80 °C, liquid nitrogen, 100 °C hot water or 121 °C autoclaving. Verify the actual specimen storage temperature before selection to avoid low-temperature detachment.
The "Material No.: freezer label series" field in the specifications area does not state the specific material code T419; the specification table has been completed per the official table. If you have specific requirements for -80 °C usability, please confirm with customer service before ordering.
