Product Features

Dedicated adapter for leaf-cutting equipment : The tube’s outer diameter and height are compatible with mainstream plant leaf‑cutting collectors, allowing cut leaves to drop directly into the tube without the need for secondary sample transfer, thereby reducing contamination.
Made of thickened PP material, it is sturdy and durable. Made from high-toughness polypropylene via one-piece molding, it is drop-resistant, compression‑resistant, and less prone to cracking, ensuring durability during field sampling and transportation.
Standard 2 mL universal volume Suitable for collecting plant leaves, young shoots, and small tissue samples, and compatible with the entire downstream workflow, including nucleic acid extraction and tissue grinding.
Clean production with no nucleic acid contamination Manufactured in a GMP Class 100,000 cleanroom; DNase/RNase‑free and pyrogen‑free; the sterile version is sterilized by irradiation.
The low-adsorption version reduces sample loss. The inner wall has been specially polished and modified to minimize the adsorption of plant nucleic acids and proteins, resulting in a higher recovery rate for trace samples.
Highly transparent tube body with graduations Clear volume markings and excellent light transmission allow for intuitive observation of the leaf sample loading level.
The conical base facilitates grinding and lysis. The conical bottom concentrates the grinding beads, allowing samples to be directly loaded into a bead‑beater for tissue lysis, enabling a one‑step workflow.
Low-temperature resistant and organic-solvent resistant The material is stable and allows for cryopreservation of samples at −80°C; it is compatible with a variety of experimental reagents, including ethanol and lysis buffers.
Multi-attribute versions available Standard, low‑adsorption, sterile‑sterilized, and sterile‑low‑adsorption combinations to meet diverse needs for field sampling and high‑throughput extraction.
Standardized bagged packaging 1,000 units per sealed bag, 5 bags per carton; ideal for bulk laboratory procurement and portioning during field sampling.
Stackable storage saves space. The tubing is neatly and uniformly designed, and the accompanying rack allows for multi‑level stacking, making storage and sample collection much more convenient.
Seamless, splicing-free tube body One-piece injection molding ensures a seamless design, preventing leakage of liquids and plant tissues and eliminating cross-contamination of samples.

2 mL Collection Tube – Frequently Asked Questions

1: What type of polypropylene material is used in this 2 mL collection tube, and in what ways does its durability manifest?

The tube is made from high‑toughness, medical‑grade polypropylene, offering excellent impact resistance and low‑temperature durability, and it remains crack‑resistant even under the intense compression and collisions associated with high‑speed shredding by the blade cutter.

1. Drop-resistant and durable: The cutter remains intact under grinding, high-speed shaking, and centrifugation, with impact resistance improved by 60% compared to standard thin-walled PP tubing.

2. Temperature resistance range: The tubing can withstand temperatures from ultra‑low cryogenic conditions of –80°C up to 121°C under high‑pressure sterilization, and repeated thermal cycling does not cause embrittlement or cracking of the tube walls.

3. Chemical resistance: The standard model is resistant to ethanol and buffer solutions; the H‑enhanced model is compatible with organic extraction reagents such as phenol and chloroform.

Selection Recommendations : For leaf grinding and pure water buffer treatment, choose the standard model; for nucleic acid–based organic extraction experiments, select the H‑corrosion‑resistant version.

2: Are 2 mL polypropylene collection tubes universally compatible with all brands of leaf‑cutting devices, and are there any size‑compatibility restrictions?

The test tubes feature standardized outer diameters and heights, making them fully compatible with mainstream tissue slicers and tissue grinders available on the market—no adapter required.

1. Standardized dimensions: The 2 mL standard tube diameter is compatible with conventional leaf‑cutting metal grinding sleeves, while the round‑bottom design optimally accommodates bead‑type grinding.

2. The self-supporting flat-bottom design does not affect compatibility: only the base is thickened, while the upper portion of the tube retains its original dimensions, allowing it to fit securely into the leaf‑cutting device’s slot.

3. Cap‑type selection guide: For high‑speed grinding of cut leaves, a push‑button cap is recommended; for high‑speed shaking with a screw cap, it is advised to tighten the cap securely to prevent leaks.

3: Can test tubes be repeatedly autoclaved and reused? Will they deform or leak after multiple sterilizations?

1. Sterilization resistance: The virgin PP material is compatible with standard steam sterilization at 121°C and 0.1 MPa, and remains deformation‑free after a single sterilization cycle.

2. Reuse limitations: It is recommended to limit repeated sterilization to no more than five cycles. Frequent exposure to high temperatures can reduce the wall toughness of the tube, making it prone to cracking during leaf cutting and grinding.

3. Note for the Sterile S Model: Once the original factory‑sterilized packaging is opened, subsequent autoclaving will invalidate the sterility indicator; therefore, this product is intended solely for non‑sterile sample experiments.

Attention : For the Z‑containing enzyme‑free coated version, repeated high‑temperature sterilization is not recommended, as heat can degrade the enzyme‑free anti‑adsorption coating and compromise nucleic acid extraction and recovery efficiency.

4: What do the product‑number suffixes S, Z, and H stand for, and how should you choose them for leaf‑cutting plant experiments?

The suffix serves as a functional‑type identifier for test tubes, accommodating the molecular‑experimental needs of different plant species:

1. S (Sterilization) : Gamma-ray irradiation ensures sterility and eliminates exogenous microbial contamination, making it suitable for aseptic sampling of fresh leaves and for collection in plant cell culture applications.

2. Z (enzyme-free) : DNase/RNase‑free, preventing degradation of plant nucleic acids; suitable for RNA/DNA extraction following leaf‑cutting.

3. H (Corrosion-Resistant Reinforced) : Thickened tube wall + formulation resistant to organic solvents, specially designed for cell lysis and extraction with organic reagents.

Combination Example : JS2PP-ZSH = 2 mL polypropylene, enzyme‑free, sterile, and corrosion‑resistant— the preferred specification for high‑throughput leaf‑tissue nucleic acid extraction.

5: What are the storage requirements for unopened vials? How long is the shelf life of the sterile version? Why are the carton‑packing specifications differentiated to include individual packaging?

Unopened vials should be stored at room temperature (10–30°C), in a dry, light‑protected environment. The sterile version has a shelf life of 24 months when unopened. Both packaging options are designed for different application scenarios.

1. Storage precautions: Avoid prolonged stacking at temperatures above 40°C; high temperatures can cause the PP material to soften, leading to deformation of the tube body and rendering it incompatible with the leaf‑cutting device’s slot. Keep away from strong organic solvents.

2. Packaging differences: The large bag containing 500 units is suitable for routine, high‑throughput leaf‑cutting experiments in the laboratory; the individual sterile bags of 50 units are ideal for single‑point sampling in field or outdoor settings, allowing on‑demand use while minimizing the risk of contaminating the entire bag.

3. Storage after opening: Once the sterile bag is opened, it is recommended to use the contents within one month. Any remaining test tubes should be sealed and stored away from light; beyond this period, they are not recommended for use with sterile plant samples.
