Our history of creating high-quality products

Our first borosilicate glass lab bottles evolved from serum bottles and were available with various Glass Packaging Institute (GPI) threads, such as 33-430 and 38-430. In Germany in 1972, we introduced the wider mouth borosilicate 3.3 glass bottles with metric GL 45 glass threads. Our history of innovation progressed alongside the evolution of the laboratory media bottles, where we introduced square lab bottles, pressure-resistant versions, and the truly wide-mouth GLS 80® bottles.

Today, we offer a wide range of reliable and reusable glass lab bottles with commonly used thread finishes, such as the GPI and German DIN GL thread standards. We mold our DURAN® ORIGINAL, WHEATON®, and KIMBLE® KIMAX® GL lab bottles from high-purity, clear, USP / EP Type I borosilicate 3.3 glass, renowned for its excellent thermal qualities and superior resistance to chemical attack. A combination of high-performance materials, robust ISO 4796-1 design, and reusability provide a long working life. The bottles feature an easy-to-read graduated volume scale and marking field in permanent white enamel.

For convenience, a circular indent on the shoulder line indicates the nominal capacity line on 100mL through 2L sizes. We supply the DURAN®, WHEATON®, and KIMBLE® KIMAX® bottles as bottles only or, if you prefer, complete with the polypropylene linerless caps and drip-free pouring rings. The DURAN® Original GL 25/32/45 bottles feature a permanent Retrace Code on each bottle for manufacturing lot traceability and certification.

Choose the materials option that best suits your application

We provide clear glass, protect+, or KimCote® plastic safety-coated glass, and amber or low actinic RAY-SORB® for light-sensitive applications. Many of the DURAN®, WHEATON®, and KIMBLE® GL lab bottles are available with a clear plastic safety coating (identifiable by the DURAN® protect+ or KimCote® branding) to provide added fortification against impact or mechanical breakage. Adding a fused, external amber or RAY-SORB® layer protects light-sensitive contents from the effects of photodegradation. Rest assured, the protection against ultraviolet (UV) light meets international USP / EP standards and lasts the bottle's lifetime.

The KIMBLE® KIMAX® lab bottles have 33-430 and 38-430 threads. We make them from high-purity, clear, USP / EP Type I borosilicate glass 33, renowned for their excellent thermal performance and high resistance to chemical attack.

Save up to 20% more space and get close and efficient packing compared to traditional round bottles when you use our innovative square DURAN® lab bottles. These bottles are ideal for shipping and storing high-demand materials or reagent supply to instruments where bench space is at a premium.


Note that the design of standard glass lab bottles does not allow them to withstand pressure differentials safely. However, the DURAN® pressure plus+ GL 45 bottles offer a safer option for laboratory vacuum or pressure applications. The bottom line? Whatever the application, DWK Life Sciences can provide a suitable laboratory bottle solution.

Frequently Asked Questions

The brown bottle commonly seen in a chemistry lab is called an amber bottle or an amber glass bottle. Amber-colored glass protects light-sensitive substances from degradation caused by exposure to ultraviolet (UV) light (within the 290 - 450 nm wavelength range). Amber bottles commonly store light-sensitive chemicals that can undergo degradation or photochemical reactions in the presence of UV light.

The capacity markings on the lab bottles indicating capacity have a tolerance level of either ± 5% or ± 10%. The International Organization for Standardization (ISO) number 4796-1:2016 does not state any nominal capacity or graduations tolerance. Because the bottles are not certified or sold as “volumetric measurement devices,” the capacity indicators should only be used as a general guide.

You can identify the nominal value by reading it off the bottle. We’ve marked the total (working/nominal) capacity as a circular indent in the "shoulder ring" of the GL bottle. This arrangement is specified in the ISO standard 4796-1:2000, "Laboratory glassware -- Bottles -- Part 1: Screw-neck bottles".

Laboratory bottles are generally not ideal for use under pressure or vacuum. However, for pressure or vacuum applications that require laboratory bottles, we recommend the DURAN® pressure plus+ protect bottle range, or the DURAN® pressure plus+ amber bottle range. Remember that the plastic coating of laboratory bottles, such as DURAN® protect or KimCote®, does not influence pressure resistance, and safety-coated products are not designed for use under pressure.

No. Only bottles manufactured from polypropylene can be autoclaved.

The maximum permissible operating temperature for a borosilicate glass lab bottle is +500 °C when used for a short time – less than 10 hours. Above a temperature of +525 °C, the glass begins to soften, and above a temperature of +860 °C, the glass changes to a liquid state.

The starting point is a clear borosilicate 3.3 glass bottle. The bottle then undergoes a unique ion diffusion process, creating an amber layer on the glass bottle with good chemical durability.

The amber DURAN® meets the requirements of USP <671> and Eur.Ph. 3.2.1. for protection against ultraviolet (UV) light. KIMBLE® RAY-SORB® meets the requirements of USP <671> EP 3.2.1. and JP 7.01 Section 5 for protection against UV light.

None of the standard plastic or glass laboratory bottles have been designed or tested with a centrifuge. However, the KIMAX® 200mL heavy-duty glass centrifuge bottles made by DWK Life Sciences are suitable for centrifuging.

Glass is much more corrosion-resistant than most materials. Borosilicate glass 3.3 is highly resistant to water, acids, saline solutions, organic substances, and halogens such as chlorine, and bromine. Its resistance to alkali is relatively high. However, only concentrated hydrofluoric acid, phosphoric acid, and strong alkalis at high temperatures (+100 °C) can cause appreciable surface removal of the glass (i.e., glass corrosion).

Both the DURAN® protect, and the KimCote® plastic-coated bottles can be autoclaved or steam-sterilized at 121 °C (20 minutes). In addition, the DURAN® protect bottles can be autoclaved at 134 °C. Dry heat resistance is 110 °C KimCote®, and 135 °C DURAN® protect. Please note that the temperature resistance only applies for short-time exposure of less than 30 minutes.

Recycling suitability depends on the type or chemical composition of the glass. Soda-lime bottles, for example, can be recycled at a standard facility.

However, you should not dispose of borosilicate laboratory glass bottles (DURAN® / WHEATON® /KIMBLE® KIMAX®) in normal bottle banks. This is because their high melting point can create problems when mixed with other glass cullet (soda-lime glass) for recycling. Instead, the customer is responsible for correct disposal, which is with the general household waste (residual waste) following the relevant guidelines and regulations.

Setting up a dedicated recycling system only for borosilicate glass types is not economical. Its market is relatively small, typically consisting of laboratory glassware, some special lighting products, and glass cookware.
