If you want to use an Object and not have all the members be static you need to reference the non-static member variables using an instance of the class.

Change:

Test_api.getQualWeight(ConStr, bin_Num, lblResults);

To:

Test_api.getQualWeight(Test_api.ConStr, Test_api.bin_Num, Test_api.lblResults);

Because ConStr, bin_Num, and lblResults are instance variables they must be references with an instance of the class - in this case Test_api.

Alternately, you could move those values into a global, static, scope by changing their declarations from:

String ConStr = "SERVER=myservername; Database=mydb; UID=mylogin; PWD=mypassword;encrypt=no;enlist=false";
String bin_Num = "201284-11-000";
Label lblResults;

To this:

static String ConStr = "SERVER=myservername; Database=mydb; UID=mylogin; PWD=mypassword;encrypt=no;enlist=false";
static String bin_Num = "201284-11-000";
static Label lblResults;
