This nylon membrane can be used for alkaline blotting and fixation, but if fixing methods such as baking and ultraviolet rays are used, higher nucleic acid detection sensitivity can be obtained. Since the nylon membrane is a hydrophilic membrane, it does not need to be immersed in ethanol, methanol and other solutions for activation. This product is only for scientific research by professionals, and must not be used for clinical diagnosis or treatment, or used for food or medicine, and must not be stored in ordinary residences. For your safety and health, please wear lab coats and disposable gloves for operation.

Snap seal vials are less prone to breakage during decapping because more glass is used in the neck of the vial. The snap seal neck finish is compatible with either crimp and/or snap seals and no special tools are required to remove the cap. These vials are recommended for short term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal.

EPA screw vials are a specific type of vial designed to meet the requirements set by the U.S.
Environmental Protection Agency (EPA) for environmental sample analysis.
These vials are commonly used for the collection, storage, and analysis of water, soil, and other environmental samples.

Grey PTFE/Moulded Butyl Septa & Grey PTFE/Pharma-fix Butyl Septa for 20mm crimp vials, Size: 20*3mm, 100pcs/pk

A headspace vial is used in the process of top gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to evaporate them at the top. Since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

Cellulose acetate is a very low protein binding membrane that is ideal for aqueous based samples and biological samples. It is a lower protein binder than either polyethersulphone or PVDF membranes, but has a lower chemical resistance than regenerated cellulose (RC). CA is a strong membrane mechanically and hydrophilic.

2ml Snap Top HPLC Vial is made of Type 1 borosilicate glass. Comparing with 9mm screw vial, this 2ml Snap Top HPLC Vial mouth is wider opening.
