SPI Supplies Large Locking Gelatin Capsules
Select from this range of empty hard gelatin capsules with a snap-action locking ring built right into its design.
Gelatin capsules are universally known for their applications in the pharmaceutical industry. What is not generally known is that there are wide-ranging applications for empty gelatin capsules in numerous fields outside of the pharmaceutical industry. For general the smaller gelatin capsules are used in microscopy and histology and the larger "jumbo" sizes are used more frequently for packaging purposes.
Empty gelatin capsules have many uses around a microscopy laboratory and are often times perceived as a lower cost alternative to products such as BEEM® capsules.
Use these hard capsules as an embedding mold when very small volumes are being used and/or when light transmission is needed. These gelatin capsules can be used as a low volume embedding mold for embedding resins, something especially valuable for those embedding resins that are on the expensive side of the norm. And of course, they are transparent to both visible and UV light, so that they can be used with resins such as SPI-Chem™ Low Acid GMA, Lowicryl™, and LR White™.
When ready for removal, the embedment can be separated from the gelatin capsule by dissolution. The gelatin capsules featured by SPI are known for their rapid dissolution properties, 90 seconds in water at 37° C/98.6° F.
Storage and shipment of fragile parts:
Empty gelatin capsules are widely used for the shipment and storage of fragile items, and represent a lower cost alternative to the well-known membrane boxes.
Large capsules are packaged in bags of 50.
While these types of capsules are widely used throughout the pharmaceutical industry and are considered "pharmaceutical grade", SPI Supplies is not registered with the US Food and Drug Administration and therefore cannot sell these gelatin capsules for applications involving pharmaceutical or clinical usage. These capsules are not for human consumption.
