These jars are traditionally called gas jars in educational settings because they were originally used for collecting and demonstrating gas properties. However, their transparent construction and tight-sealing caps make them equally suitable as specimen jars for preserving biological and geological specimens. The terms are often used interchangeably for this type of cylindrical glass or plastic jar with a tight-fitting cap.
Polystyrene has good compatibility with many aqueous preservative solutions such as formalin (formaldehyde solution) and ethanol at typical preservation concentrations. However, it may not be suitable for strong organic solvents, concentrated acids, or bases. For long-term preservation with specific chemicals, always test a small sample first or consult chemical compatibility charts.
No, these specimen jars are made from polystyrene, which has a relatively low melting point and is not autoclavable. Standard autoclaving temperatures (121°C) would cause deformation and melting. They are designed for ambient temperature storage of preserved specimens. For sterile applications, specimens should be preserved using aseptic techniques before placement in these jars.
The cap is designed to fit tightly by pressing firmly onto the jar rim. Ensure both the jar rim and cap are clean and free from debris before sealing. Press down evenly until the cap is fully seated. The tight fit creates a secure seal that prevents evaporation of preservative fluids and protects specimens from dust and contaminants.
These specimen jars have dimensions of ø 50 mm (diameter) x h150 mm (height). This provides approximately 150 mm of internal height with a 50 mm diameter opening, making them suitable for a wide range of specimen sizes from small insects to moderate-sized biological samples.
Yes, these jars are suitable for wet specimen preservation using appropriate fixatives and preservatives such as formalin or alcohol. The tight-fitting cap helps contain the preservative solution and prevent evaporation. However, ensure the cap is securely sealed and check periodically for any signs of leakage or evaporation, especially with long-term storage.
Polystyrene is generally recognized as safe for food contact, but these jars are specifically designed for laboratory specimen preservation. While they could technically be used for storing dry food items, we recommend using containers specifically manufactured and labeled for food storage to ensure compliance with food safety regulations.
These specimen jars are supplied in packs of 12 pieces (Code 40001), making them economical for educational institutions and laboratories with regular specimen preservation needs.
Yes, labeling is recommended for proper specimen identification. The smooth polystyrene surface accepts most permanent markers and laboratory labels. For best results, use solvent-resistant labels or markers, especially if the jars will be handled frequently or if the preservative solutions might come in contact with the labeling.
