Clear Glass Sample Bottles for Samples

The sample bottle is leaking and the contents are unclear? KANG HUA's transparent model precisely fits the bill.

Addressing industry pain points: Ordinary sample bottles have loose seals, causing liquid leakage, waste, and contamination; the capacity is either too small or too large, and the 30ml - 50ml common capacity range is missing; the bottle's light transmission is poor, making it difficult to distinguish the sample state. These problems make reagent dispensing, sample storage, and sample shipping challenging. KANG HUA's Clear Glass Sample Bottles for Samples precisely resolves these issues. With a 30ml - 50ml golden capacity, a 22mm diameter × 33mm height compact design, combined with a tight sealing structure, it is transparent and leak-proof, durable, and better suited for static storage than small transparent spray bottles. It is also more practical than 5ml clean spray bottles, providing both safety and accuracy in sample storage.

Product Description

KANG HUA This transparent sample bottle is made by a single-blowing process of high borosilicate glass. The bottle body is completely transparent without any impurities, allowing for clear display of the sample color and state, facilitating observation of the remaining volume and purity. It strictly follows the size standard of 22mm diameter × 33mm height, which can be held in the palm and does not occupy storage space. It offers a capacity selection of 30ml - 50ml, perfectly meeting the common needs such as laboratory small samples, beauty product trial packs, and food testing samples. The bottle mouth is equipped with a food-grade PP inner stopper + spiral outer cover, featuring a dual-sealing design. A built-in silicone sealing gasket ensures no leakage when inverted, and it is different from the spray bottle transparent structure, making it more suitable for long-term sample storage to avoid volatilization or contamination. The edge of the bottle body has been finely polished, without burrs that can irritate the hand. The bottle mouth diameter is compatible with regular pipettes and funnels, making it less likely to spill during filling. A flat label area is reserved on the bottle body for easy labeling of sample names, dates, etc.

Technical Specifications

The bottle body is made of high borosilicate glass, with a temperature resistance range of -20℃ - 120℃. It can withstand hot water disinfection and low-temperature refrigeration, and is less likely to crack due to sudden temperature changes; the thickness of the bottle body is ≥ 1.8mm, with 25% stronger anti-drop performance than ordinary glass sample bottles. The sealing performance has passed a 48-hour inverted test without leakage; the capacity error is ≤ ± 0.5ml, and the measurement accuracy meets the sample storage standards. The size is 22mm diameter × 33mm height, which can be stacked without occupying space and is suitable for laboratory sample racks, cosmetic bags, and courier packaging boxes, etc.; the PP outer cover is wear-resistant and odor-free, and the silicone sealing gasket is resistant to acid and alkali corrosion, and does not age when in contact with various samples such as reagents, skin care products, and food. All materials have passed food contact safety certification and laboratory equipment standards certification, with no harmful substances leaching, making use more放心.

Product Features 

High borosilicate transparent glass + dual sealing, preventing leakage and providing clear visibility, making sample observation more convenient and storage more secure than ordinary sample bottles；

30ml - 50ml gold capacity + 22mm × 33mm compact size, suitable for common sample volumes, portable and easy to store, not occupying space when stacked；

Compatible with multiple scenarios, the nozzle design is more suitable for static storage than spray bottle transparent, with a capacity more flexible than 5ml clean spray bottles, suitable for reagents, small samples, and testing samples, etc.

Tips 

When screwing the cap, ensure the inner stopper is fully sealed against the bottle mouth, and the outer cover is tightened properly to avoid a semi-sealed state that may cause leakage or volatilization；

After cleaning, it is necessary to dry thoroughly before use, especially the bottle mouth gap, to prevent residual moisture from affecting sample purity；

Avoid direct contact with sharp objects. Although its anti-drop performance is better than ordinary glass, severe collisions may still cause damage. Store away from the edge position. Application scenario

The laboratory uses it to package reagent samples. The transparent body makes it easy to observe the reaction state, and the sealed design prevents contamination. The 22mm diameter fits standard sample holders. The beauty brand uses it to store small samples of skincare products. The 30ml - 50ml capacity is just right to meet the trial needs, and it is more suitable for膏状 and thick liquid than the small transparent spray bottle. The food testing institution uses it to seal the testing samples. The double sealing ensures that the samples are not contaminated, and the precise capacity is convenient for measurement. The e-commerce sellers use it to send liquid samples. The leak-proof design reduces transportation losses, and the compact size saves shipping costs. In daily life, it can also be used to store essential oils, medicinal alcohol, etc. The transparent body allows you to clearly see the remaining amount, which is more suitable for long-term storage than the spray bottle transparent. Customers' benefits

By choosing this sample bottle from KANG HUA, the double sealing design avoids sample leakage and waste, saving raw material costs; the transparent visibility feature allows you to observe the sample state without opening the cap, reducing the risk of contamination； the 30ml - 50ml capacity is suitable for common scenarios, and you don't need to frequently separate as with 5ml clean spray bottles, improving efficiency. The compact size saves storage and transportation space, reducing warehousing and logistics costs； the borosilicate glass material is durable and reusable, more environmentally friendly and cost-effective than disposable containers. For laboratories, beauty, and testing industries, the precise size and capacity, and reliable sealing performance can ensure sample quality and enhance professional work.

Customer reviews and recommendations

Mr. Chen, a laboratory technician, said： "The previous sample bottles always leaked and contaminated the laboratory table. After changing to this one, the double sealing is extremely tight, and the transparent body allows you to directly observe the sample state. The 22mm diameter fits perfectly into the sample holder, and it is much more practical than the small transparent spray bottle." Ms. Li, a beauty store owner, commented： "Used to store small samples of skincare products, the 30ml capacity just meets the customer's trial needs. The sealing is good and there is no leakage, and it is more popular than 5ml clean spray bottles, with a high customer retention rate." Teacher Wang from the testing institution recommended： "For sealing testing samples, choose this one. The transparent material does not affect observation, the double sealing can ensure sample purity, the regular size is convenient for unified management, and it is more suitable for static storage than the spray bottle transparent. I have recommended it to my colleagues."
