A biological sampling apparatus (10, 110) comprising: a barrel (12, 112) defining a chamber (16, 116) having a first end (14, 114) and a narrow passageway (18, 118) at a second end (17, 117) opposite the first end (14, 114); an absorbent analytical test means (20, 120) located in the chamber; a hydrophilic wick (44, 144) extending through the narrow passageway (18, 118); and a splash filter (42, 142) located in said chamber (16, 116), characterised in that said splash filter (42, 142) is at least in part hydrophobic and is (a) of a frit (40, 140) having a portion constituting the wick (44, 144) which is integral with said splash filter (42, 142), at least a portion of the wick (44, 144) being treated with a wetting agent so as to be hydrophilic; (b) integral and in contact with the hydrophilic wick (44, 144) such that a portion of the splash filter (42, 142) adjacent the wick (44, 144) is hydrophilic and a portion thereof closest said test means (20, 120) is hydrophobic; or (c) is hydrophobic and located in said chamber (16, 116) adjacent said narrow passageway (18, 118), and said wick (44, 144) has a first portion extending through the narrow passageway (18, 118) and a second portion located outside said passageway and outside said barrel, said second portion having a bulbous portion capable of absorbing more fluid sample than said first portion. a barrel (12, 112) defining a chamber (16, 116) having a first end (14, 114) and a narrow passageway (18, 118) at a second end (17, 117) opposite the first end (14, 114); an absorbent analytical test means (20, 120) located in the chamber; a hydrophilic wick (44, 144) extending through the narrow passageway (18, 118); and a splash filter (42, 142) located in said chamber (16, 116), characterised in that said splash filter (42, 142) is at least in part hydrophobic and is (a) of a frit (40, 140) having a portion constituting the wick (44, 144) which is integral with said splash filter (42, 142), at least a portion of the wick (44, 144) being treated with a wetting agent so as to be hydrophilic; (b) integral and in contact with the hydrophilic wick (44, 144) such that a portion of the splash filter (42, 142) adjacent the wick (44, 144) is hydrophilic and a portion thereof closest said test means (20, 120) is hydrophobic; or (c) is hydrophobic and located in said chamber (16, 116) adjacent said narrow passageway (18, 118), and said wick (44, 144) has a first portion extending through the narrow passageway (18, 118) and a second portion located outside said passageway and outside said barrel, said second portion having a bulbous portion capable of absorbing more fluid sample than said first portion. (a) of a frit (40, 140) having a portion constituting the wick (44, 144) which is integral with said splash filter (42, 142), at least a portion of the wick (44, 144) being treated with a wetting agent so as to be hydrophilic; (b) integral and in contact with the hydrophilic wick (44, 144) such that a portion of the splash filter (42, 142) adjacent the wick (44, 144) is hydrophilic and a portion thereof closest said test means (20, 120) is hydrophobic; or (c) is hydrophobic and located in said chamber (16, 116) adjacent said narrow passageway (18, 118), and said wick (44, 144) has a first portion extending through the narrow passageway (18, 118) and a second portion located outside said passageway and outside said barrel, said second portion having a bulbous portion capable of absorbing more fluid sample than said first portion.
