These 2mL clear screw-thread vials (12 x 32mm) meet the diverse needs of various customers. Designed as standard vials for GC and HPLC applications, they feature a narrow opening and an 8-425 standard screw-thread finish. They are suitable for use with autosamplers and for sample storage, and are designed to be paired with 8-425 screw caps and septa.

The proper method for opening these 2mL clear screw-thread vials is as follows:

Check the seal: Before opening the vial, inspect the seal between the cap and the vial opening. Ensure there is no damage or looseness to prevent leakage or contamination.

Prepare tools: You may use your fingers, sterile gloves, or a sterile cotton swab to open the vial. Ensure that any tools used are clean and sterile to prevent sample contamination.

Hold the vial body firmly: Hold the vial body with one hand to keep it steady. This helps prevent the vial from slipping or tilting and provides better control.

Unscrew the cap: Hold the cap with your other hand and rotate it clockwise. Apply moderate force, but do not overtighten or force the rotation, as this could damage the cap or cause a leak.

Inspect the contents: After opening the cap, examine the sample inside. Ensure there are no unusual odors, abnormal colors, or other suspicious characteristics. If any abnormalities are detected, consult a qualified professional or follow laboratory protocols for handling such issues.

Reseal the cap: Promptly reseal the cap after using the sample. Ensure the cap is screwed on tightly to prevent leakage or external contamination.

Please note: Before opening the vial, ensure you are familiar with and adhere to relevant laboratory safety regulations and operating procedures. This includes wearing appropriate personal protective equipment (PPE) and following aseptic handling protocols. Properly opening the vial helps maintain sample quality and purity, ensuring the accuracy of experimental results.
