The question asks for the specific in-process control equipment that checks tablet or capsule weight variation by measuring reflected energy rather than by physically weighing each unit. Each named device can be considered in turn:
- Rotofill: This is a filling and closing machine used mainly in hard gelatin capsule production to dose the fill material and seat the cap on the body. It is a filling device, not a weight-checking instrument, so it does not match the description.
- Vericap-1200: This is a capsule sorting and weight-checking unit that typically works by weighing individual capsules mechanically and rejecting out-of-range units, rather than by using reflected energy as its sensing principle.
- Rotosort: This equipment is used to sort and orient capsules or tablets (for example, arranging them correctly for printing or inspection) rather than to measure their weight variation.
- Rotoweight: This is an online weight-checking device that uses a reflected energy (optical sensing) principle to continuously monitor tablet or capsule weight variation during high-speed production, flagging or rejecting units outside the acceptable weight range.
Only the last device is built specifically for weight-variation monitoring using a reflected-energy sensing method.
Therefore, the correct answer is Rotoweight.

Choose the correct answer from the options given below: - The initial concentration of a drug decomposing according to first order kinetics is28 units/mL. The specific decomposition rate, k, obtained from an Arrhenius plot is 2.09 × 10-5 hr-1 at room temperature, 25°C. Previous experimentation has shown that when the concentration of the drug falls below 15 units/mL it is not sufficiently potent for use and should be removed from the market.
