In the modern landscape of high-performance analytics, chromatography, and diagnostics, precision is not just a standard—it is a baseline requirement. The 1.5 mL glass vial (often standardizing around the nominal 2 mL capacity in standard autosamplers) serves as the lifeblood of laboratory diagnostics, biotechnology research, pharmaceutical stability testing, and high-end cosmetic assays. These micro-vials are critical in protecting highly volatile analytes and expensive chemical formulations from external cross-contamination and hydrolytic leaching.
Globally, the market for 1.5 mL vials has transitioned from a basic laboratory commodity to a highly engineered system. Advancements in Type I Borosilicate 3.3 and 5.0 expansion glass have ensured that issues such as chemical leaching, septa degradation, and dimensional deviations are minimized. As diagnostic laboratories implement automated High-Performance Liquid Chromatography (HPLC) and Gas Chromatography-Mass Spectrometry (GC-MS) autosamplers, the demand for vials with uniform dimensions, micro-level structural tolerance, and optimized neck geometry has reached unprecedented levels.
Utilizing premium Class A USP Type I borosilicate glass prevents the alteration of sample pH values, ensuring clean chromatogram readouts and elimination of "ghost peaks."
Offering integrated glass micro-inserts (down to 100 µL usable capacity) directly inside the 1.5 mL footprint for low-volume sample extractions without loss.
Engineered with specialized screw-thread (9-425) or crimp finishes that guarantee seamless sealing and eliminate evaporate-loss failures.
Our manufacturing capacity operates under strict ISO 9001 and ISO 13485 (Medical Device Quality Management System) standards. By merging mechanical automation with digital optical inspection, our production yields reflect the pinnacle of reliability required by tier-one pharmaceutical brands and diagnostic companies.
Lecos Glass (Lecospack) has been dedicated to the glass packaging industry for over 10 years with our innovative wholesale glass bottles and jars for cosmetics, perfume, personal care, essential oils, and candle jar glass packaging. We pride ourselves on being exceptional at offering bespoke glass solutions tailored to our clients’ brand identities.
Basically, we have a large range of glass bottles, jars, and accessories you’ll ever need! Although we have hundreds of products, our collections include Fancy Dropper Bottles, Boston Round Bottles & Accessories, Glass Skincare Packaging, Glass Bottle Tops & Accessories, Glass Perfume Bottles, and Wholesale Candle Jars.
We provide professional glass packaging solutions to worldwide customers. With years of experience in the field, we are capable of providing innovative, stable quality, and cost-effective packaging according to the customer's DNA. The quality of our glass products is strictly controlled, winning the favor of domestic and international customers, and we work directly and indirectly with many leading brands.
At Lecospack, our operation centers around three primary pillars that guarantee business continuity and risk reduction for global procurement managers:
Rigorous dimensional control, stress-resistance checking, and surface inertness audits ensure that every single glass vial is structurally sound and chemically stable.
Through supply chain vertical integration and Factory 4.0 automation, we optimize material waste and pass directly on to our partners the cost efficiency of bulk manufacturing.
A proactive customer support network offering rapid technical consultation, custom-mold planning, sample provisions, and end-to-end logistics tracking.
Our company is built on a solid foundation of deeply held values that set us apart, steer our actions, and infuse every aspect of our corporate culture. These values are not just words; they are the principles that guide how we operate daily. Central to our business practices is our unwavering commitment to social responsibility, adherence to ethical standards, and steadfast support for universal human rights.
We are dedicated to protecting the environment by reducing carbon emissions in glass firing processes, utilizing post-consumer recycled (PCR) glass when requested, and minimizing wastewater output. We support creativity and innovation, celebrating the richness of diversity, and treating our employees with the utmost respect and care. By upholding these values, we ensure that Lecospack remains a responsible, ethical, and inspiring business partner for global enterprises.
The global laboratory and cosmetic supply chain has faced major challenges over the past few years. In response, China's advanced manufacturing hubs have evolved through Factory 4.0 modernization. This transition means integrating high-definition vision systems, intelligent automated raw material mixing, and real-time annealing temperature feedback controls.
For buyers of 1.5 mL glass vials, this translates into unmatched physical uniformity. Autosamplers require micro-vials to have a thread diameter variance of less than 0.1 mm to avoid needle breakage. By shifting away from manual monitoring to AI-assisted infrared scanning of hot-end glass tubing, our production line dynamically recalibrates parameters mid-run. Furthermore, our post-processing capabilities—including frosting, customized silkscreen printing, precision electroplating, and chemical stabilization—give brands the ability to source both standard laboratory consumables and bespoke high-end cosmetic packaging from a single, resilient supply node.

Our prices are subject to change depending on supply, raw material costs, and other market factors. We will send you an updated price list after your company contacts us for further information.
Yes, we require all international orders to have an ongoing minimum order quantity. If you are looking to resell or procure in smaller quantities, please contact our team to check our current inventory stock.
Yes, we can provide most documentation including Certificates of Analysis (COA) / Conformance; Material Safety Data Sheets (MSDS); Insurance; Certificates of Origin, and other export documents where required.
For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment. Lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products. If our lead times do not work with your deadline, please discuss your requirements with your sales representative. We will always try to accommodate your schedule.
You can make the payment to our bank account, Western Union, or PayPal: 30% deposit in advance, and the remaining 70% balance against the copy of the Bill of Lading (B/L).
We warranty our materials and workmanship. Our commitment is to ensure your complete satisfaction. Whether within the official warranty period or after, it is a core value of our company to address and resolve all customer issues to mutual satisfaction.
Yes, we always use high-quality, reinforced export packaging. We also use specialized hazard packing for dangerous goods and validated cold storage shippers for temperature-sensitive items. Custom packaging or non-standard packing requirements may incur an additional charge.
Shipping costs depend on the delivery method you choose. Express shipping is the fastest but also the most expensive. Ocean freight is the most cost-effective solution for large-volume orders. We can provide exact freight rates once we know the details of your order size, total weight, and shipping destination. Please contact us for a detailed freight quote.
