408VK4 Bottle, 100ml, Clear, Graduated, Glass — Global Buyer's Guide [2026]

The 408VK4 Bottle, 100ml, clear, graduated, glass is a 100 ml capacity clear glass laboratory bottle with printed graduations, used for measuring, storing, and dispensing liquids in analytical, environmental, and industrial quality-control laboratories. It is typically manufactured from borosilicate 3.3 glass for thermal and chemical resistance.

What is a 408VK4 Bottle, 100ml, clear, graduated, glass?

A 408VK4 Bottle, 100ml, clear, graduated, glass is a small-volume laboratory container made from clear borosilicate glass, marked with volume graduations up to 100 ml, and sealed with a screw cap. It is designed for reagent preparation, sample transport, and routine volumetric work where visual clarity and chemical inertness matter.

Clear glass is preferred over amber when the contents are light-sensitive only in the short term, or when the analyst needs to inspect fill level, colour, or turbidity. Graduated markings allow approximate volume reading without a separate graduated cylinder, which speeds up bench workflows.

Brands such as CYTIVA WHATMAN and LABEXACT are widely referenced in laboratory consumables for their quality-controlled glass and filtration products, and 3G Electric supplies comparable lab-grade glassware alongside these lines for global customers.

How does a graduated glass bottle work?

The bottle body is moulded or blown from borosilicate glass, then annealed and printed with fired-on enamel graduations. The screw neck accepts a PP or PTFE-lined cap that seals against vapour loss and contamination.

Because the graduations are printed on the outside wall, the user reads volume at eye level against the meniscus. Accuracy is typically ±5% of nominal volume for general-purpose graduated bottles — sufficient for reagent make-up but not for Class A volumetric analysis.

Key specifications to verify

Types and applications in Worldwide markets

Graduated glass bottles are supplied in clear and amber variants, with capacities from 25 ml to 1000 ml. The 100 ml size is the most common bench size for reagent aliquots and QC sampling.

In Worldwide markets, they are used in pharmaceutical QC, environmental water testing, food and beverage analysis, petrochemical sampling, and university teaching labs. Export buyers frequently request borosilicate 3.3 certification and lot traceability for regulated applications.

Related consumables such as CYTIVA WHATMAN 934-AH Glass Microfiber Filter 9 cm and LABEXACT 934-AH Glass Microfiber Filter 4.25 cm are commonly ordered alongside graduated bottles for gravimetric and filtration workflows.

How to select the right graduated glass bottle

1. Confirm capacity and graduation range. A 100 ml bottle should be graduated from at least 20 ml to 100 ml for useful working range.
2. Check glass type. Borosilicate 3.3 is standard for thermal and chemical resistance; soda-lime is cheaper but less durable.
3. Match the closure. PP caps suit general use; PTFE-lined caps are required for aggressive solvents and autoclaving.
4. Verify autoclavability. Confirm both bottle and cap are rated for 121 °C steam sterilisation if required.
5. Consider light sensitivity. Choose amber glass if contents degrade under UV or visible light.
6. Check regulatory documentation. For pharma and food use, request material certificates and lot traceability.
7. Plan for export. Confirm packaging meets international transit requirements and that documentation supports your customs regime.

Product comparison — lab consumables ladder

Step up the ladder when sample volume or particulate loading increases — larger diameter filters handle higher throughput without clogging. For gravimetric work requiring minimal extractables, CYTIVA WHATMAN 934-AH grade is the reference standard.

For pipe identification in fuel-oil systems feeding laboratory boilers, BRADY #2 Fuel Oil Fiberglass Pipe Marker provides compliant labelling for pipes 8 inches and larger.

Frequently asked questions

What is a 408VK4 Bottle, 100ml, clear, graduated, glass used for?
It is used for measuring, storing, and dispensing liquids up to 100 ml in laboratories and industrial QC. Typical applications include reagent preparation, sample collection, water testing, and pharmaceutical analysis where clear visibility and chemical inertness are required.

Is the 408VK4 bottle autoclavable?
Borosilicate 3.3 bottles are typically autoclavable at 121 °C for 20 minutes. However, the cap material determines overall suitability — PP caps may deform, so verify cap rating or use PTFE-lined caps before sterilising.

What is the difference between clear and amber graduated bottles?
Clear glass allows visual inspection of contents and is suitable for most reagents. Amber glass blocks UV and visible light, protecting light-sensitive compounds such as vitamins, dyes, and certain pharmaceuticals. Choose amber when photodegradation is a risk.

How accurate are the graduations on a 100 ml glass bottle?
General-purpose graduated bottles are typically accurate to ±5% of nominal volume. For analytical work requiring higher accuracy, use Class A volumetric glassware instead. Graduated bottles are intended for approximate measurement and reagent preparation.

Can 3G Electric ship 408VK4 bottles worldwide?
Yes. 3G Electric supplies worldwide with export documentation experience, incoterms-neutral options, and support for cross-market requirements. Contact us for lead times, packaging specifications, and customs documentation for your destination.

What related consumables should I order with graduated bottles?
Common companion items include glass microfiber filters for gravimetric analysis, such as CYTIVA WHATMAN 934-AH 9 cm and LABEXACT 934-AH 3.7 cm, plus pipe markers for laboratory fuel systems.
