Polypropylene G Tube Snap Cap Tube by Bio Plas, 500 Pack

Description

Product Overview

The 4049 model from Bio Plas offers a premium polypropylene microcentrifuge tube designed for precision laboratory work. Each tube holds 0.6mL of liquid and features a snap‑cap that securely seals the container without the need for additional locking devices. The interior surface is polished to a high shine, creating a non‑wettable environment that prevents liquids from adhering to the walls, which enhances sample recovery and reduces cross‑contamination risk. The tube walls are engineered for high impact resistance, delivering durability even under rigorous handling and repeated autoclave cycles. Packaged in a convenient bulk quantity of 500, these tubes are available in assorted colors, allowing easy visual identification of different sample types or experimental conditions.

Usage

These tubes are ideally suited for a wide range of laboratory applications, including molecular biology protocols such as PCR, qPCR, and DNA/RNA extraction, as well as protein assays, enzyme reactions, and cell culture sampling. The snap‑cap design enables quick and reliable sealing, which is essential for high‑throughput workflows where time efficiency is critical. Because the tubes are autoclavable, they can be sterilized repeatedly without compromising structural integrity, making them a cost‑effective choice for labs that require strict aseptic conditions. The color‑coded options facilitate organization in multi‑step experiments, allowing researchers to quickly differentiate between reagents, controls, and test samples. Their robust construction also makes them suitable for field work, where samples may be subjected to transport and handling stresses.

Why Choose Us

Bio Plas has a long history of manufacturing high‑quality laboratory consumables, and the 4049 G‑tube reflects that commitment to excellence. The tubes undergo rigorous quality control testing to ensure consistent wall thickness, cap fit, and interior polish across every batch. This attention to detail translates into reliable performance, reducing the likelihood of tube breakage or cap leakage during critical experiments. Additionally, the tubes are produced using medical‑grade polypropylene, which is chemically inert and compatible with a broad spectrum of reagents, solvents, and buffers. Our customers benefit from responsive technical support and a straightforward return policy, reinforcing confidence in the product’s reliability and our dedication to service.

FAQ

What is the maximum temperature for autoclaving these tubes?

The tubes can be autoclaved at standard laboratory conditions of 121°C (250°F) for up to 30 minutes without deformation.

Can the snap‑cap be reused after opening?

Yes, the snap‑cap is designed for multiple uses; it maintains a tight seal after repeated opening and closing.

Are the tubes compatible with standard microcentrifuge rotors?

Absolutely, the 0.6mL size conforms to the dimensions of common microcentrifuge adapters and rotors.

Do the color options affect the chemical resistance of the tube?

No, the color additives are inert and do not alter the polypropylene’s resistance to chemicals or solvents.

What is the recommended storage condition for unopened tubes?

Store in a cool, dry place away from direct sunlight; the tubes remain stable for several years under these conditions.
