750ml Brown Reagent Bottle

In every aspect of scientific experimentation, industrial R&D, and fine chemicals, containers for holding, storing, and processing samples are more than just tools; they are the cornerstone for ensuring data accuracy, ensuring experimental safety, and maintaining sample purity. A high-quality brown reagent bottle is a silent yet crucial partner in your experimental process. Today, we solemnly recommend this durable, scientifically designed 750mL brown reagent bottle, which will become a trusted standard in your laboratory workflow.

Target Users and Product Positioning

Core target users:

Research institutes and university laboratories: Our chemical brown reagent bottle is used to store various chemical reagents, standard solutions, biological samples, culture media, buffer solutions, as well as intermediates or samples to be tested produced during the experiment.
Pharmaceutical and biotechnology companies: Used to store raw materials, semi-finished products and active ingredients that need to be kept away from light during drug research and development, quality control and production.
Chemical and food companies: Used for industrial-level sample analysis, quality control, and packaging and short-term storage of small batches of fine chemical products.
Medical and testing institutions: used to store test samples, diagnostic reagents, chemiluminescent liquid, etc.
Independent researchers and serious hobbyists: Providing professional-grade storage solutions for the home lab or small studio.

Product Positioning:

This is a high-standard, general-purpose laboratory glassware for professional use. It balances moderate capacity with ease of use. Its wide-mouth design is particularly suitable for handling solids.

Design material: ingenious craftsmanship creates excellent quality

1. High-Quality Glass Material

The brown reagent bottle is made of borosilicate glass 3.3 (similar to GG-17). This glass resists high heat and sudden temperature changes. It can handle temperature shifts over 200°C. You can safely heat it on a hot plate or dry it in an oven. The glass also resists most acids, bases, and organic solvents. Only hydrofluoric acid and hot concentrated phosphoric acid can damage it. This keeps your samples pure.

2. Easy-to-Use Wide Mouth

The brown reagent bottle mouth is smoothly fire-polished. The wide opening makes it easy to pour or scoop out solid powders. You can clean it thoroughly with a brush. It also allows easy sampling with a spatula or spoon. Large stirring bars fit easily into the bottle.

3. Secure Seal

The bottle neck follows standard thread specifications. It works with common PP/PE plastic caps or phenolic resin caps. When closed, the seal is tight. This prevents evaporation, leaks, and keeps out contaminants. Your samples stay stable for a long time.

4. Eco-Friendly & Reusable

Unlike plastic containers, this glass bottle can be reused. You can clean and sterilize it with steam or dry heat many times. This reduces lab costs and plastic waste. It supports green lab practices.

Function List: Multi-functional integration to cope with various scenarios

Core storage function: safe storage of various chemical liquids, solid powders, crystals, culture media, standard solutions, etc.
Heating and drying treatment: It can withstand high temperatures and can be directly used for water bath heating, electric heating plate heating, or placed in an oven or autoclave for drying and sterilization.
Display and Sampling: The transparent reagent bottle is suitable for sample display. The wide mouth allows for quick and accurate sampling using a variety of tools.

Key Advantages: Why Choose Our 750mL brown reagent bottle?

1. Chemical stability and inertness: The borosilicate glass material ensures that it will not react with the contents, with no dissolution or adsorption, ensuring the absolute purity of the sample and the accuracy of the experimental data. This is a core advantage that plastic containers cannot match.
2. Temperature Resistance and Durability: Able to withstand both high-temperature sterilization and low-temperature freezing, it has an extremely wide application temperature range (approximately -80°C to 500°C). Its high physical strength and long service life offer a one-time investment with long-term benefits, and its cost-effectiveness far exceeds that of disposable products.
3. Operational Convenience: The wide-mouth design is a perfect tool for handling solids and viscous liquids. Whether adding large samples, taking samples with a spatula, or performing thorough cleaning, it becomes exceptionally easy, significantly improving work efficiency and reducing operational hassles.

Preparation Before Use

First Use

Clean the bottle before first use.Use a lab cleaner or mild detergent with a bottle brush.Clean the inside and outside thoroughly.Rinse well with pure water.Let it drain or dry before use.

Sterilization (If Needed)

If sterility is required:Clean the bottle first.Wrap the mouth with kraft paper or foil.Sterilize in dry heat at 160–180°C for 2 hours.Or sterilize with steam at 121°C for 20–30 minutes.Let it cool naturally before use.

Packing and Sealing

Choose the right cap and bottle type (clear/brown) for your sample.Do not fill the bottle completely. Leave space for expansion or mixing.For volatile samples, close the cap quickly after filling.Tighten the cap gently. Too much force can damage the glass.

Storage and Handling

Store in a cool, dry, and ventilated place.Avoid strong impacts. The glass is strong but can break if hit hard.When heating, wear heat-resistant gloves. Make sure the bottle is dry.After use at high or low temperature, let the bottle warm or cool slowly at room temperature. Do not heat or cool it suddenly.
