The DSA dual-mode verification traps (DMVT)

The DSA dual-mode verification traps (DMVT) have revolutionized the verification procedure – One Trap, in and Done. Each trap is pre-dosed with the perfect amount of Verification A & B; the entire verification process takes about 27 seconds. Are you still wasting sample traps and extra gloves on the verification procedure? Are you still hit with high costs when screeners drop those expensive cans? Does your ETD oversaturate with explosive material from screeners pressing down too hard on the cans? The lower cost, dual-mode trap solves all of these problems.

The L3Harris QS-B220™ requires calibration to ensure accurate detection. DSA Detection produces these and all QS-B220 consumables in small batches, testing each batch, every time, with the highest of standards. The packaging of DSA’s calibration, verification and sample traps has been engineered to fit inside our optional dispensing box for the busiest security checkpoints to ensure the product is free from contamination.

Clean cotton- or Nitrile gloves are required when handling sample, calibration or verification traps to prevent contaminants such as natural oils, dirt and lotions from interfering with the performance of the instrument.

DSA also offers QS-B220 accessories and replacement parts to lower the cost of owning the instrument and to improve efficiencies in any security checkpoint. Trace instruments are affected by even the smallest amount of debris or humidity, which is why frequent replacement of air purification parts such as sieve canisters and the air filter is essential. Checkpoint accessories (screening bins, bowls, carts, isopropyl alcohol, etc.) are also available.
