High-Frequency FAQ for the Tip Series

1: What’s the difference between the 10 μL extended‑length model (JSXL10 series) and the 39 mm model (JSXM10 series), and how should I choose?

The key difference lies in length and intended applications: the extended version measures 45.8 mm, while the 39-mm version is 39 mm long; both are compatible with 10 µL pipettes, but they are suited to different types of containers.

1. Extended version (45.8 mm): Compatible with deep-well plates (e.g., 96‑well or 384‑well deep-well plates), enabling aspiration to the bottom of the wells and minimizing residual liquid.

2. 39 mm model: Compatible with standard centrifuge tubes, reagent bottles, and other shallow-depth containers; shorter in length for greater operational flexibility.

Selection Recommendations : For high-throughput experiments using deep-well plates, choose the extended-length version; for standard single-tube sampling, opt for the 39 mm version.

2: What do the D, F, and S suffixes in the product codes signify, and what are their respective application scenarios?

The suffix serves as an identifier for the pipette tip’s core functionality; different combinations correspond to distinct experimental requirements.

1. D (Low Adsorption) : The inner wall has been specially treated to minimize the adsorption of biomolecules such as proteins and nucleic acids, making it suitable for sample‑sensitive assays like ELISA and qPCR.

2. F (filter element) : The tip features a built-in filter that prevents aerosols from entering the pipette body, thereby minimizing cross-contamination; it is ideal for applications such as nucleic acid extraction and viral detection.

3. S (Sterilization) : Sterilized by gamma-ray irradiation, achieving a sterility level of 100, suitable for cell culture and sensitive experiments conducted within a sterile workbench.

Combination Example : JSXL10-FDS = 10 μL extended tip + filter + low-binding + sterilized, suitable for nucleic acid extraction in sterile environments.

3: Are the tips in this series compatible with mainstream pipette brands on the market? Do special specifications (such as extended‑length 200 μL tips) require dedicated pipettes?

All pipette tips in the series comply with the ISO universal size standard and are compatible with pipettes from leading brands such as Eppendorf, Thermo, Gilson, Bio-Rad, and Dalong—no special adapters required.

1. Standard specifications (200 μL, 1000 μL): Compatible with single-channel and multi-channel pipettes of the corresponding volume range;

2. Special specifications (extra‑long 200 μL, 39 mm 10 μL): These differ only in length; the interface dimensions are identical to the standard models, and the corresponding‑volume pipettes can still be used without the need to purchase additional specialized equipment.

4: What are the advantages of the low‑adsorption version (with the “D” suffix) compared to the standard version? Can the low‑adsorption version be used in routine experiments?

1. Core Advantages : The low‑adsorption model features a dual‑process inner wall treatment—hydrophilic coating plus polishing—resulting in liquid residue of ≤0.1 μL, compared to approximately 0.5 μL for the standard model, thereby delivering a more pronounced improvement in recovery rates for trace samples (e.g., 2 μL or less).

2. Applicable Scenarios : Recommended for experiments with small sample sizes and low concentrations (e.g., single-cell PCR, rare‑target nucleic acid detection);

3. General experimental compatibility : For routine experiments—such as aliquoting standard reagents or pipetting large volumes—low‑adsorption tips may be used; however, they are slightly more expensive. From a cost‑effectiveness standpoint, it is recommended to select based on specific needs.

Attention : Low‑adsorption models cannot be sterilized at high temperatures (as this will damage the coating). For reusable items, rinse with enzyme‑free water to prevent detergent residue.

5: Can the filter element of the cartridge‑type model (with the “F” suffix) be reused? How long does its protection against aerosol contamination last?

1. How to Use the Filter Cartridge The filter cartridge is designed for single use and should be discarded after each sampling; it must not be disassembled or reused, as reuse may cause blockage or contamination.

2. Pollution prevention effect The filter element can capture aerosol particles ≥0.2 μm; as long as the pipette tip remains intact during the experiment, its anti-contamination performance persists until the tip is discarded.

3. Applicable Scenarios : Particularly well suited for handling high-concentration samples (such as virus-positive specimens), it effectively prevents contamination of the pipette body and avoids cross-contamination in downstream experiments.

6: What is the sterile shelf life of the sterilized version (S‑suffix)? How should unused pipette tips be stored after opening?

When unopened, the sterile shelf life is 24 months (subject to the manufacturing date indicated on the packaging); once opened, it must be stored strictly in accordance with aseptic procedures.

1. Store after opening. : The package must be opened inside a laminar flow hood. Any remaining pipette tips should be returned to their original packaging, sealed, and stored in a clean, dry, light‑protected environment to prevent moisture or dust contamination.

2. Usage period : After opening, it is recommended to use the product within one month. If this time limit is exceeded, re-sterilization is required (only PP material can withstand 121°C autoclaving; after sterilization, the “sterile” label becomes invalid, but the product may still be used for non‑sterile experiments).

7: Are the yellow model (e.g., JSX300KY) and the blue model (e.g., JSX1000B) different only in color, or do they have any other functional differences?

The core functionality of the colored version is identical to that of the transparent version with the same specifications; it only adds a “visual differentiation” feature, with no other performance differences.

1. Yellow style : Primarily designed for 200 μL/300 μL tips (e.g., JSX300KY, JSX200KY), enabling quick identification of medium-capacity pipette tips during experiments.

2. Blue style : Primarily intended for large-volume tips of 1000 μL/1250 μL (e.g., JSX1000B, JSX1250B) to prevent confusion with medium-capacity tips.

Advantageous Scenarios : When using pipette tips of multiple volumes simultaneously (e.g., performing 200 μL aliquoting and 1,000 μL transfers at the same time), color coding can help reduce the likelihood of selecting the wrong tip.

8: Why are small-volume tips (10/200 μL) packaged 20 per box, while large-volume tips (1000/1250 μL) are packaged 5 per box?

Packing specifications are designed based on “usage frequency + weight per bag,” balancing convenience with transportation costs:

1. Small-volume pipette tip : The laboratory has a high usage frequency (e.g., 200 μL for routine pipetting); 20 pouches per box (totaling 20,000 tips) can meet long-term needs, reducing the frequency of reorders.

2. Large-capacity pipette tip : Each tip is heavier (approximately 0.8 g per 1000 μL tip), and the box contains 5 bags, totaling 5,000 tips, which helps keep the overall box weight within a manageable range (about 4 kg), facilitating handling while also preventing tip deformation from prolonged storage.

9: Does the tip length (e.g., a 200 μL tip that’s 89 mm long) affect pipetting accuracy? Can short tips be used for sampling in deep-well plates?

1. The Relationship Between Length and Precision : The tip length does not affect pipetting accuracy (which is determined by the pipette and the smoothness of the tip’s inner wall); it only influences the sampling depth.

2. Limitations of the short-suction nozzle : Short pipette tips (e.g., the standard 200 μL type, 52 mm) cannot reach the bottom of deep-well containers (such as 50 mL centrifuge tubes or deep-well plates), leading to liquid residue and compromising sample recovery rates.

3. Advantages of the long suction nozzle : The extended-length version (e.g., 89 mm) can reach the bottom of deep containers, making it ideal for aspirating viscous liquids or small residual volumes, thereby minimizing waste.

Attention : When using long pipette tips, ensure that the pipette’s stroke is sufficient to prevent the tip from failing to aspirate liquid completely (e.g., using a 100 μL pipette with an 89 mm‑long tip may result in inaccurate volumes due to insufficient stroke).

10: How should unopened pipette tips be stored? Will long-term storage degrade their performance?

Unopened pipette tips should be stored at room temperature (10°C–30°C), in a dry environment (relative humidity ≤60%), and protected from light, avoiding high temperatures, high humidity, or direct sunlight.

1. Performance influencing factors : High temperatures (>40°C) can cause PP material to soften, compromising the tip’s seal; high humidity can lead to moisture on the inner wall of the tip, potentially fostering microbial growth (for non-sterile models).

2. Long-term storage recommendations : Within the shelf life (24 months unopened), provided storage conditions are compliant, the pipette tips will maintain their smoothness, seal integrity, and other performance characteristics. After the expiration date, we recommend performing a precision test first—such as weighing after dispensing—and using only if the results meet the required standards.

Special Attention : Low-adsorption version (D suffix) – Avoid prolonged contact with organic solvents such as ethanol and methanol, as this may damage the low-adsorption coating.
