Frequently Asked Questions Back to Elizatips Main page “Black Spots” on my tables…how can I resolve this problem?
• If you are noticing “black spots” on your tablets, it may be due to wom or missing dust cups or dust seals. Elizabeth-Hata has several FDA-approved options to help remedy this problem: • Dust seals (strictly for the Hata Tablet Press) • Dust cups (recommended for any type of tablet press) • Dust cups with bellows • European-style dust cups (groove on punches required) • Every tablet press should have some type of seal separating the lubrication areas from the product to prevent “black spots”. • Dust cups are placed at the end of the upper punches to contain any excess lubricant • Elizabeth-Hata’s dust cups are inexpensive, easy to replace, and also are available in FDA red and clear colors. The red colored dust cups are highly visible when using a white product powder. • European-Style dust cups are long-lasting and washable • Bellows add additional containment when used with dust cups.
