5.9.2 Prepare two beakers of the same size and label them as a1 & a2 consider it as set 1, these are for 10 ml.
5.9.3 Similarly prepare beakers for 25 ml, 50 ml, 100 ml & 200 ml and label them as b1 & b2, c1 & c2, d1& d2 and e1 & e2 respectively.
5.9.4 Weigh the beakers and note the readings.
5.9.5 Transfer the material to the pass box (Incubator room to LAL test room).
5.9.6 Enter the room according to SOP for entry and exit in microbiology testing area.
5.9.7 Transfer all the material into pass box (LAL test room to Buffer room).
5.9.8 Enter the ‘sterility test area’ as per SOP.
5.9.9 Enter into the buffer room and collect all the material from the pass box (Buffer room to LAL test room) and transfer it into cRABS pass box.
5.9.10 Install the steritest canister in steritest equinox. Pre-wet the membrane filter with 100 ml of filtered purified water and filter the same.
5.9.11 Keep 10 ml purified water vial on to stand. Make sure the bottom plugs of the canisters are closed.

5.9.17 Repeat the procedure from point No. 5.9.11 to 5.9.16 with below mentioned sets.
Vial Quantity
Pump Speed
Pump from canister to beaker set
25 ml
50

50 ml
50
c1 & c2
100 ml
100
d1& d2
200 ml
150
e1 & e2
5.9.18 After completion of the activity transfer all accessories from work chamber of cRAB to the pass box of the cRAB and from pass box of the cRAB to pass box (Autoclave room to Buffer room). Clean the cRAB with the sporicidal agent.
5.9.19 Take care while transport, the liquid should not come out and spill, where it will give erroneous results.
5.9.20 Weigh the beakers with the liquid already transferred and note the readings.
5.9.21 Calculate the % difference with following formula:
% Difference = [1 – C1 / (C1 + C2 / 2)] x 100
C1 = Net weight in grams of the water collected in canister 1 (a1 / b1 / c1 / d1 / e1)
C2 = Net weight in grams of the water collected in canister 2 (a2 / b2 / c2 / d2 / e2)
% Difference = Splitting capacity (difference in percentage compared to average volume)
5.9.22 Acceptance criteria - % Difference must be less than or equal to 10 % of average volume.
5.9.23 Frequency - Once in six months
Note: In case of failure to meet the acceptance criteria, intimate to the Quality Assurance Department to assess the impact and subsequently to service engineer to rectify the problem.
