Labcon Security Cups for Urine or Specimen Collection

• 100 mL Cups
• Sample spouts may be cut with scissors or pierced with a syringe
• Impact and pressure resistant seal

These security containers are designed to provide secure and reliable tamper-proof seals for specimens in transit or storage. After specimen collection the screw cap is tightened first by hand, then by the special wrench, which engages teeth on the lids rim to create a locked and leak-proof seal. To access the specimen for testing procedures, large or small sample spouts may be cut with scissors or pierced with a syringe. Spouts can be resealed with the large or small plugs and returned to storage for further testing. The impact-resistant, durably constructed, and pressure-resistant seal offers excellent protection during handling and transport. Made of non-reactive polyethylene resin.

Labcon SuperSpin® Microcentrifuge Tubes

• Ultra-high centrifuging up to 40,000 x G*
• Optically clear resin
• Resin will not interfere with DNA or PCR
• For Phenol/Chloroform vortexing
• Reduced Thumb Force
• Autoclavable (122°C) and freezable (-80°C)
• Packaged in resealable bags
• Tubes have flat pierceable caps and a side writing surface
• Graduated

SuperSpin® microcentrifuge tubes were designed with the ability to extract DNA from samples and then amplify that DNA with reliable results in mind.  They can be trusted to spin at high rates and can be opened and closed easily many times to add or remove agents.  The interior surfaces are ultra-smooth with low retention.  The tubes are clear enough to be use in spectrophotometers and have no extractables at the wavelength ranges you use to detect DNA. SuperSpin® microcentrifuge tubes are more than twice as effective at transmitting light than most brands of micro centrifuge tubes.

*Maximum G-force can be affected by organic solvents, multiple spin cycles, or low temperature storage.

Cytiva 3MM Chr paper is the world's most widely used blotting paper.

This acceptance and usage reflect the high quality, purity and consistency that are relied upon by researchers doing Southern, Northern and Western transfers. 3MM Chr paper is now available in the most widely used sizes. A medium thickness paper (0.34 mm) used extensively for blotting in electrophoresis for lifting of sequencing gels.

GB004
A thick gel blotting paper (1.0 mm), used for wicking purposes only. Provides higher absorbency and more consistent wicking than paper towels. Recommended for applications where fewer layers of gel blotting paper must still ensure a high capacity. Fewer layers of blotting paper reduce the risk of trapping air bubbles. Recommended for capillary blotting of nucleic acids.

GB005
An extra-thick (1.2 mm ), highly absorbent paper recommended for applications where fewer layers of blotting paper must siill ensure a high capacity. Recommended for semi-dry blotting of proteins.

17 Chr
A thick (0.92 mm) and highly absorbent paper.

31 ET
An extremely fast and thick paper (0.5 mm) with a fairly soft surface.

Features and Benefits

• Pure cellulose produced entirely from the highest quality cotton linters with no additives of any kind. Ensures that no contamination will occur during the transfer steps
• Manufactured and tested specifically for chromatographic techniques. This ensures the wicking capability and uniformity of capillary action that is important in obtaining clean and even transfers during blotting
• Cytiva 3MM Chr is considered the industry standard for blotting procedures
• Convenient sizes available in sheets precisely cut to the most popular gel and transfer membrane sizes. Allows "out-of-the-box" usage and eliminates sheet-to-sheet variations

3MW is used widely in nucleic acid and protein research for blotting, wicking, spacers, and gel drying due to its purity, quality and consistent results. Uniform capillary action provides even wicking and enables gel transfers to be lifted RELIABLY from glass supports.
