Glass syringes 1–50 mL (all-glass, ground-glass plunger): barrel and plunger — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/glass-syringes/ (CC BY 4.0) Basis: KD Scientific glass syringe datasheet (order codes 78-0871 to 78-0877, the Tomopal glass series; also Tomopal 140-4002 and 140-4550): piston OD, barrel OD D1, barrel collar D2, piston collar D3, length L. Luer cone per ISO 594-1 as given in BD's syringe data sheet. Catalog version: 2026-10-20 Sizes: see table below - Published per size (KDS / Tomopal datasheet), and drawn exactly: plunger (piston) OD, which is the barrel bore of a ground-glass syringe; barrel OD (D1); barrel collar Ø (D2); piston collar Ø (D3); length L. 1 mL Ø4.80 bore / Ø8.30 OD / L 115.00; 2 mL 6.45 / 9.95 / 115.00; 5 mL 12.60 / 15.40 / 105.00; 10 mL 15.15 / 18.35 / 128.50; 20 mL 20.40 / 24.20 / 145.50; 30 mL 22.90 / 27.30 / 163.00; 50 mL 27.45 / 32.35 / 178.00. Every one of these five numbers is verified for every size drawn. - Drawn but not published (my geometry, so the parts are whole): the datasheet does not name L's end points, so L is drawn from the Luer tip end to the top of the barrel collar (the plunger is not in it: 1 and 2 mL share L = 115 while their strokes differ); the tip is a male Luer cone per ISO 594-1 (Ø3.925 at the end, 6 % taper, 7.5 long, Ø1.2 bore at the standard's minimum); the closed end wall is as thick as the barrel wall; both collars are 3 mm thick and round (the real barrel collar has two flats, width not published); the plunger rod is as long as the bore, so the collars meet when the plunger bottoms. The metal Luer-lock collar is not drawn (its outside is not defined by ISO 594-2 and not given in the datasheet). - 3 mL is left out: the series has no 3 mL and I found no other datasheet that gives a 3 mL glass barrel's OD, length and collar. Brands differ: the syringe-pump tables give the Popper (Micro-Mate) glass bores as 1 mL 4.50, 2 mL 8.92, 3 mL 8.99, 5 mL 11.7, 10 mL 14.7, 20 mL 19.6, 30 mL 22.7, 50 mL 29.0 mm (the bores most DIY builds quote); those are listed in the table for reference but not drawn, because no Popper OD, length or collar size is published. - In the existing frames: the plastic-syringe sockets are Ø15.9 (alpha V-twin frame, V block, Ross frame, LTD top plate, tri-clamp syringe head, syringe-cradle-10ml). A glass 5 mL barrel (Ø15.40) goes in with 0.50 mm diametral play (it does not grip: the socket is 0.25 mm per side oversize); a glass 10 mL (Ø18.35) does not go in. syringe-cradle-20ml (Ø21.0) fits no glass size; syringe-cradle-60ml (Ø29.0) takes a glass 30 mL (Ø27.30) with 1.70 play, not a 50 mL (Ø32.35). The syringe-pistons (Ø14.5 / 19.1 / 21.7) are plastic-barrel bores and fit no glass barrel: a glass syringe runs on its own plunger. - Stroke volume per mm = bore² × π / 4: 5 mL 0.125 mL/mm, 10 mL 0.180 mL/mm. The 5 mL is the power piston of the mug LTD and the test-tube marble engine; glass-syringe-plunger-clevis takes the con-rod. size bore_mm barrel_od_mm barrel_collar_mm piston_collar_mm length_mm ml_per_mm popper_bore_mm verified_and_drawn 1 mL 4.8 8.3 14.95 11.5 115.0 0.0181 4.5 bore, OD, collar Ø, piston collar Ø, length 2 mL 6.45 9.95 16.4 12.25 115.0 0.0327 8.92 bore, OD, collar Ø, piston collar Ø, length 3 mL None None None None None None 8.99 not drawn: no published barrel OD / length / collar found 5 mL 12.6 15.4 22.25 17.25 105.0 0.1247 11.7 bore, OD, collar Ø, piston collar Ø, length 10 mL 15.15 18.35 26.2 19.95 128.5 0.1803 14.7 bore, OD, collar Ø, piston collar Ø, length 20 mL 20.4 24.2 33.25 24.65 145.5 0.3269 19.6 bore, OD, collar Ø, piston collar Ø, length 30 mL 22.9 27.3 37.55 27.95 163.0 0.4119 22.7 bore, OD, collar Ø, piston collar Ø, length 50 mL 27.45 32.35 44.0 34.05 178.0 0.5918 29.0 bore, OD, collar Ø, piston collar Ø, length Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - KD Scientific: Full Line of Glass Syringes, rev.
